Studies were conducted to know the damage potential and effect of insecticides on leaf area feeding and larval mortality of the common Mormon butterfly, Papilio polytes Cramer in the homestead garden and germplasm center of the Patuakhali Science and Technology University (PSTU) campus and in the laboratory, Department of Entomology, PSTU, Patuakhali, Bangladesh during October to December 2016. Ten Citrus host plants such as Kagoji lime-BAU-1, BAU-2, BAU-3, BAU-4, BARI kagoji, elachi lime, sweet orange, orange, jamir and pumelo were used as study materials. To determine the effects of insecticides on leaf area feeding and larval mortality, five treatments viz., T1 = Voliam flexi 300SC @ 0.5 ml/l of water, T2 = Voliam flexi 300SC @ 1.0 ml/l of water T3 = Bioneem Plus @ 0.5 ml/l of water, T4 = Bioneem Plus @ 1.0 ml/l of water T5 = control were applied. Under natural field conditions, the highest percentage of leaf infestation was recorded in orange, followed by BAU-3, BAU-4, malta and elachi lime, while the lowest percentage was in BARI kagoji on 23 and 30 November, 2016. At the top canopy, the highest percentage of leaf infestation was recorded in orange and elachi (56%), while the lowest was in BAU-4 (8%). At the middle canopy, the highest percentage of leaf infestation was recorded in orange (56%), while the lowest was in jambura (12%). At the lower canopy, the highest percentage of leaf infestation was recorded in BAU-3 (40%), while the lowest was in elachi (8%). At the top canopy, significantly the highest percentage of infested leaves per branch was observed in orange (51.39%) and the lowest percentage of infested leaves per branch was in BAU-4 kagoji lime (10.86%). At middle and lower canopies, no significant difference was observed in the percentage of infested leaves per branch among different citrus varieties. The lowest percentage (6%) of leaf area consumed by 4th instar larva was recorded in T2 (Voliam flexi 300SC @ 1.0 ml/l of water) treated leaf, while the highest percentage of leaf area consumption was found in T5 (control) at 3 HAT. The highest percent mortality (100%) of larvae was found in T2 treated citrus plant, while the lowest percent mortality was in the T3 (70%) treated plant. No mortality was recorded in the untreated control (T5) plant. J. Asiat. Soc. Bangladesh, Sci. 47(1): 35-46, June 2021

Studies were conducted to know the developmental period and host preference of the lime swallow tail butterfly, Papilio polytes romulus Cramer and leaf consumption by its larvae on citrus in the laboratory. Ten Citrus host plants such as Kagoji lime-BAU-1, BAU-2, BAU-3, BAU-4, BARI kagoji, elachi lime, sweet orange, orange, jamir and Pumelo were used as study materials. Results revealed that the most preferred host of Papilio polytes romulus L. was Elachi followed by BAU-3 and Orange while the least preferred host was Pumelo. Eggs were pale yellow and spherical. The average length of newly hatched caterpillars, 2nd, 3rd, 4th and 5th instar larvae were 2.32 mm, 10.75 mm, 14.50 mm, 24.80 mm and 39.50 mm, respectively. The mean duration of 1st, 2nd, 3rd, 4th, 5th instar larvae and pre-pupa were 2.20, 2.15, 2.35, 2.25, 2.35 and 1.0 days, respectively. The average length of the pupal stage, adult male and female butterfly were 29.50, 24.00 and 25.75 mm, respectively. The mean longevity of female and male was 6.5 and 3.9 days. The percentage of leaf area consumed was increased with increasing the age of larvae. The highest percentage of leaf area was consumed by the 5th instar larva (100) followed by 4th instar (75) while the lowest percentage of leaf area was consumed by the 1st instar larva (15) in 72 hours after release.

AbstractMost of the cotton bollworm-resistant genes applied in cotton are more than 20 years and they all belong to Cry1Ab/c family, but the insect-resistant effects of Cry5Aa on cotton were rarely reported. The possible risk of resistance is increasing. The study synthesized a novel bollworm-resistant gene Cry5Aa artificially based on preferences of cotton codon. The new gene was transferred to cotton through the method of pollen tube pathway. The transgenic strains were identified by kanamycin test in field and laboratory PCR analysis. Meanwhile, an insect resistance test was conducted by artificial bollworm feeding with transgenic leaves and GK19 was used as a control in this study. Results showed that rate of positive transgenic strains with kanamycin resistance in the first generation (T1), the second generation (T2) and the third generation (T3) respectively were 7.76%, 73.1% and 95.5%. However, PCR analysis showed that the positive strain rate in T1, T2 and T3 were 2.35%, 55.8% and 94.5%, respectively. The resistant assay of cotton bollworm showed that the mortality rate of the second, third and fourth instar larva feed by the transgenic cotton leaves, were 85.42%, 73.35% and 62.79%, respectively. There was a significant difference between transgenic plant of Cry5Aa and GK19 in insect resistance. Finally, we also conducted the further analysis of gene expression patterns, gene flow and the effect on non-target pest in the study. The results showed that Cry5Aa gene had less environmental impact, and Cry5Aa has been transferred successfully and expressed stably in cotton. Therefore, the novel bollworm resistance gene can partially replace the current insect-resistance gene of Lepidoptera insects.

Abstract Background Spodoptera litura (Fab.) (Lepidoptera: Noctuidae) is a serious agricultural pest that infests many commercially important crops of Southeast Asian countries. Indiscriminate use of chemical pesticides has led to various health hazards as well as insecticide resistance. Entomopathogenic fungi (EPF) provide an important alternative as biological control agents. Metarhizium rileyi is an EPF with a specific host range for lepidopteran pests. The present study aimed to identify virulent M. rileyi isolate against S. litura larvae and analyse their extracellular cuticle-degrading enzyme activities. Results Three M. rileyi isolates viz M. rileyi NIPHM, M. rileyi MTCC 4254 and M. rileyi MTCC 10395 formulations were evaluated at different concentrations against 2nd instar larvae of S. litura. A maximum percent mortality of 63.33% was recorded in M. rileyi NIPHM (12 g/l), followed by M. rileyi MTCC 4254 (58.33%) at the same concentration, 10 days post-treatment. Maximum means of chitinase, protease and lipase activities (0.44, 1.58 and 2.95 U/ml, respectively) were recorded in the case of M. rileyi NIPHM. Correlation analysis was positive between enzyme activity and larval mortality. Conclusions Metarhizium rileyi NIPHM recorded the highest enzymatic activity and exhibited the maximum mortality rate against 2nd instar larvae of S. litura, suggesting the possible role of these enzymes in the pathogenicity of the fungus. Further knowledge in this regard may help in the development of enzyme-based screening methods for selecting virulent fungal isolates for the eco-friendly management of crop pests.

AbstractThe area of individual leaves in oil palm has been conventionally estimated from a regression equation that is based on the size and number of leaflets. The aim of the present study is to verify the accuracy of this equation, which became standard in oil palm research. Therefore, true leaf area, measured with a video camera, was estimated from the product of number of leaflets per leaf (n) with mean length (l) times mid-width (w) of six of the longest leaflets (nlw). The database was assembled, annually for the first 4 years after planting, from 2961 leaves of dura × pisifera testcrosses descending from six distinct pisifera origins. The regression coefficients of the regression lines of nlw plotted against true area did not show a trend with age of the palms or a difference among pisifera origins. The common regression equation fitted through all data of this study accurately estimated true leaf area of the testcrosses and also the areas of 2- to 3.5-year-old dura palms of three distinct origins as well as 18-year-old tenera palms. These outcomes are at odds with the conventional regression equation that overestimates the true leaf areas by about 24%. A more recently-developed variant underestimates true area of the young tenera and dura palms by 28%, while overestimating true area of old tenera palms by 19%. Possible causes for these deviations from true area are discussed. The paper argues that parameters depending on leaf area of previous physiological studies need to be reassessed.

Evidence is presented from data covering the period 1940 to 1952 which corroborates the conclusion of previous studies that prior tonsillectomy probably adversely affects the occurrence of brainstem paralysis (bulbar and bulbospinal) in poliomyelitis. Neither this study nor any preceding studies relating to this problem have proved the contention. On the basis that the hypothesis is correct, an attempt is made to find an answer by studying the incidence of the common paralysis of cranial nerves (VII, IX and X and XI) in bulbar and bulbospinal cases of poliomyelitis on the basis of presence or absence of tonsils. Rates of incidence of paralysis of cranial nerves, not adjusted for age, indicate a decidedly higher proportion of paralysis of the facial nerve (VII) among nontonsillectomized patients whereas tonsillectomized persons are preportionately more affected by palatal and pharyngeal paralysis (nerves IX and X). Paralysis of the facial nerve appears from two studies to occur more commonly at earlier ages, particularly in the age group 0 to 4 years. However, age adjustment did not erase, although it did somewhat lower, the TR/TP ratio. This finding lends credence to a real difference but can only be applied to this study, as Paffenbarger in a smaller study found no significant difference in frequencies of paralysis of the facial nerve between groups with tonsils removed and tonsils present, and Southcott, also in a small study, found paralysis of the facial nerve more common among tonsillectomized patients with bulbar (includes bulbospinal) involvement. The differences noted for palatal and pharyngeal paralyses (nerves IX and X) in the unadjusted rates as between tonsillectomized and nontonsillectomized patients remain statistically different and in some instances significant when corrections for age are made. The results of this study are suggestive but give no entirely satisfactory explanation for the differences noted. Various explanations previously offered are cited and briefly discussed. Perhaps more definitive studies in animals along the approach suggested by Southcott will prove more fruitful, namely, labelling virus by some radioactive element in order to trace the route it takes to the central nervous system.

Multiple organ dysfunction syndrome (MODS) is a key factor that leads to death in elderly patients with sepsis. Therefore, early prevention and treatment of gastrointestinal dysfunction (GIDF) in elderly patients with sepsis is an important measure to prevent MODS occurrence. This research explores the correlation between intestinal microflora and GIDF in elderly patients with sepsis and provides ideas for the prevention and treatment of GIDF in elderly patients with sepsis. In this study, 152 patients with sepsis (122 patients with sepsis and GIDF) treated in the Third Affiliated Hospital of Yunnan University of Chinese Medicine from January to September 2019 were selected as the sepsis group and 100 elderly who had normal physical examination results were selected as the control group. The common intestinal microflora of the two groups was compared. Patients with sepsis and GIDF were treated as the GIDF group and the other patients with sepsis were treated as the non-GIDF group. The common intestinal microflora, gastrointestinal indicators, serum inflammatory factors, and immune function indices were compared between the two groups. Correlation analysis of the observed indices with statistical significance was carried out. The results showed 152 patients with sepsis and 122 patients with sepsis and GIDF; thus, the incidence of sepsis with GIDF was 80.26%. The total average score of sepsis with GIDF was 3.61±0.09. There was no statistically significant difference in GIDF scores of patients ages 65–75 and > 75 years old. The number of Bifidobacterium and Lactobacillus in elderly patients with sepsis was lower and the number of Escherichia coli was higher than in the control group. In elderly patients with sepsis, the number of Bifidobacterium and Lactobacillus in the GIDF group was lower and the number of E. coli was higher than in the non-GIDF group. White blood cell (WBC) count, procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), gastrin (GAS), and diamine oxidase (DAO) in GIDF patients were higher and motilin (MOT), CIT (CIT), CD4+, and CD8+ were lower than in the non-GIDF group. WBC count, PCT, CRP, TNF-α, GAS, and DAO were negatively correlated with the number of Bifidobacterium and Lactobacillus but positively correlated with E. coli. MOT, CIT, CD4+, and CD8+ were positively correlated with the number of Bifidobacterium and Lactobacillus but negatively correlated with E. coli. There was a negative correlation between Bifidobacterium and Lactobacillus and GIDF score and a positive correlation between E. coli and GIDF score. Therefore, the change in the intestinal microflora in elderly patients with sepsis is related to GIDF.

PURPOSE: To study the frequency of cervical spine dysfunction (CCD) signs and symptoms in subjects with and without temporomandibular disorder (TMD) and to assess the craniocervical posture influence on TMD and CCD coexistence. METHODS: Participants were 71 women (19 to 35 years), assessed about TMD presence; 34 constituted the TMD group (G1) and 37 comprised the group without TMD (G2). The CCD was evaluated through the Craniocervical Dysfunction Index and the Cervical Mobility Index. Subjects were also questioned about cervical pain. Craniocervical posture was assessed by cephalometric analysis. RESULTS: There was no difference in the craniocervical posture between groups. G2 presented more mild CCD frequency and less moderate and severe CCD frequency (p=0.01). G1 presented higher percentage of pain during movements (p=0.03) and pain during cervical muscles palpation (p=0.01) compared to G2. Most of the TMD patients (88.24%) related cervical pain with significant difference when compared to G2 (p=0.00). CONCLUSION: Craniocervical posture assessment showed no difference between groups, suggesting that postural alterations could be more related to the CCD. Presence of TMD resulted in higher frequency of cervical pain symptom. Thus the coexistence of CCD and TMD signs and symptoms appear to be more related to the common innervations of the trigeminocervical complex and hyperalgesia of the TMD patients than to craniocervical posture deviations.

Dengue is vector-borne diseases with 390 million infections per year extending over 120 countries of the world. Aedes aegypti (L.) (Diptera: Culicidae) is a primary vector for dengue viral infections for humans. Current focus on application of natural product against mosquito vectors has been the main priority for research due to its eco-safety. The extensive use of chemical insecticides has led to severe health problems, environmental pollution, toxic hazards to human and nontarget species, and development of insecticide resistance on mosquitoes. Azolla pinnata is an aquatic fern and predominantly used as feed in poultry industry and as fertilizer in agricultural field for enhancing the fertility of rice paddy soil. The present study was conducted to explore the larvicidal efficacy of A. pinnata using fresh and powdered form against late third-stage larvae (6 days, 5 mm in larvae body length) of Ae. aegypti (L.) (Diptera: Culicidae). The larvicidal bioassays were performed using World Health Organization standard larval susceptibility test method for different concentration for powdered and fresh A. pinnata. Powdered A. pinnata concentration used during larvicidal bioassay ranges from 500ppm to 2000ppm; meanwhile, fresh A. pinnata ranges from 500ppm to 9,000,000 ppm. The highest mortality was at 1853 ppm for powdered A. pinnata compared with fresh A. pinnata at 2,521,535 ppm, while the LC50 for both powdered and fresh A. pinnata recorded at 1262 ppm and 1853 ppm, respectively. Finally, the analysis of variance (ANOVA) showed significant difference on Ae. aegypti larval mortality (F=30.439, df=1, p≤0.001) and concentration (F=20.002, df=1, p≤0.001) compared to powdered and fresh A. pinnata at 24-hour bioassay test. In conclusion, the powdered A. pinnata serves as a good larvicidal agent against Ae. aegypti (L.) (Diptera: Culicidae) and this study provided information on the lethal concentration that may have potential for a more eco-friendly Aedes mosquito control program.

The use of biochar as a soil amendment in forest ecosystems can be beneficial in the restoration of degraded soils. Forest insects such as the Douglas-fir tussock moth, Orgyia pseudotsugata (McDonnough) (Lepidoptera: Erebidae), may be exposed to biochar when the material is applied. Two experiments were conducted using biochar either (1) applied to the surface of the diet at three rates (0, 5, and 10 mg) or (2) incorporated into synthetic diet at four rates (0, 10, 20, and 40% volume/volume). The objective of both experiments was to determine if biochar on the surface or incorporated into a synthetic diet affected development and survival of O. pseudotsugata larvae. In both experiments, there was a significant decrease in estimated time to larval mortality in all biochar treatments compared to untreated controls. In the surface-applied biochar experiment, there was a significant difference in larval weight gain at day 12 between the control and 10 mg biochar treatments. In the experiment with biochar incorporated into the diet, mean larval weight at day 12 was highest in the low (10%) biochar treatment compared to all other treatments, although weight gain was only significantly different between the low- and high-concentration (40%) biochar treatments. Our results suggest that larvae, feeding on a low amount of biochar in the synthetic diet, may respond by engaging in compensatory feeding behavior. Fewer surviving larvae in the biochar treatment groups may contribute to the lack of significance found in the comparison of weight gain at day 24 in each experiment.

The aim of this study is to have an idea on the molecular mechanisms of C. albicans resistance to fluconazole in Burkina Faso, by studying the polymorphism of the ERG11 gene, and its implication in the C. albicans virulence and resistance in vivo according to the Galleria mellonella model; (2) Methods: Ten (10) clinical strains including, 5 resistant and 5 susceptible and 1 virulent and susceptible reference strain SC5314 are used. For the estimation of virulence, the larvae were inoculated with 10 μL of C. albicans cell suspension at variable concentrations: 2,5.105, 5.105, 1.106, and 5.106 CFU/larva of each strain. For the in vivo efficacy study, fluconazole was administered at 1, 4 and 16 mg/kg respectively to G. mellonella larvae, after infection by inoculum 5.106 CFU / larvae of each strain; (3) Results: Six (6) non-silent mutations in the ERG11 gene (K143R, F145L, G307S, S405F, G448E, V456I on ERG11p) were found in 4 resistant isolates. Larval mortality depended on fungal burden and strain. The inoculum 5.106 CFU caused 100% mortality in 2 days for the 2 CAAL-1 and CAAL-2 strains carrying the F145L mutation, in 3 days for the reference strain SC5314, in 4 days for the ensemble of resistant strains, and in 5 days for the ensemble of susceptible strains. The comparison of the mortality due to the reference strain SC5314 CFU / larva and the average mortality due to the two mutant F145L strains, shows a significant difference (P <0.05).Fluconazole significantly protected (P> 0.05) the larvae from infection by susceptible strains and the reference strain. However, 100% mortality in 6 days after injection of the resistant strains, was observed (4) Conclusions: Certain mutations in the ERG11 gene such as the F145L mutation are thought to be a source of increased virulence in Candida albicans. Fluconazole effectively protected larvae from infection by susceptible strains in vivo, unlike resistant strain
