One new and two known species of Dorylaimoidea (Nematoda) from West Bengal, India

Small populations of Laimydorus istvani sp. n., Laimydorus baldus Baqri & Jana, 1982 and Dorylaimus sp. were collected fromthe soil around the roots of guava at south 24-Parganas district, West Bengal, India. Laimydorus istvani sp. n. is characterizedby its odontostyle being distinctly thicker than the cuticle at the same level, cardia shape: rounded-conoid, wide at pharyngo-intestinal junction, enveloped by intestinal tissue which forms a conical projection extending into the lumen of intestine;delicate ring-like structure between the pharyngeal base and the proper cardia. Laimydorus istvani sp. n. comes close to L.multialaeus (Khera, 1970) Baqri, 1985, L. siddiqii Baqri & Jana, 1982 and L. baldus Baqri & Jana, 1982, but can bedistinguished from these species on the basis of different morphometric measurements. The new species differs from L.multialaeus in having higher a value, lower b value and longer odontostyle in females, and. longer body, lateral guiding piecesand tail in males. From L. siddiqii the new species differs in having a shorter tail in relation to body length, shorter cardia withdifferent shape, shorter prerectum and longer rectum in female, different number of ventromedian supplements and shorterspicules in males. From L. baldus, it differs in having a longer body, greater a-value, longer odontostyle and odontophore andlonger tail in females. Laimydorus istvani sp. n. differs from the males of L. baldus by its longer body, greater c value and in thenumber of ventromedian supplements. The population of L. baldus from West Bengal agrees well with the original descriptionexcept for some variations in body, odontophore, prerectum and tail length. New data on male characters have been provided inthe present study. The specimens of Dorylaimus sp. come close to D. geraerti Baqri & Jana, 1986 except in some morphometricmeasurements including: b (4.2–5.1 vs. 4.3–4.7), odontophore length (33–54 μm vs. 40–43 μm, prerectum length in females(120–160 μm vs. 196–241 μm and tail length in females (247.5–294 μm vs. 249–406 μm). In males, the supplements (36 innumber) occur in a contiguous series (as is usually seen in the genus Dorylaimus Dujardin, 1845), whereas in the typespecimens of D. geraerti 35–38 supplements are largely contiguous except for a set of 4–5 spaced supplements in the middle of the series, showing a resemblance with the genus Ischiodorylaimus Andrássy, 1969.

Abstract Myctolaimus platypi sp. n. is described and figured. The third-stage dauer juveniles of M. platypi sp. n. were isolated from the underside of the elytra of the oak borer, Platypus quercivorus, and were reared on an Asparagine-Mannitol (A-M) agar. Specimens of adult nematodes for description and measurements were collected from a 2-week-old culture on A-M agar. The new species is characterised by having the stoma shorter than the pro-metacorpus, shape of the rounded-cylindroid pro-metacorpus, the obvious longitudinal striations on the cuticle, and thick cuticle. The male and female of the new species have a body length of ca 700-1000 μm, a value of ca 20, b value of ca 6, and c value of ca 10. Males of the new species have strongly arcuate, C-shaped spicules 71 (62-80) μm long, 29 (25-35) μm long gubernaculum with pointed distal end, and nine pairs of caudal papillae. There is no bursa. Ceratosolenus is proposed as a junior synonym of Myctolaimus and the following new combinations are also proposed: M. anoplophorae comb. n.; M. inevectus comb. n.; and M. racemosa comb. n.

<p><em>Physicochemical properties are one of the parameters of honey quality that impacts the sales of honey as well as the economy condition of the society in Ciwidey and Bogor. The physicochemical properties of honey are significantly influenced by the origin of the honey, including its geographical location and vegetation. This study aims to determine the physicochemical properties between multiflora honey from Ciwidey and Bogor with different source of nectar where Ciwidey honey is dominated by calliandra nectar while Bogor honey is dominated by kapok nectar. Data were analyzed with descriptive and quantitative method using independent t test for data with normal distribution (water content and reducing sugar content). Data that were not normally distributed (color analysis and acidity value) were tested non-parametrically with the Mann Whitney-U. The results showed that Bogor honey has the better physicochemical properties and meets Indonesian National Standard (Standar Nasional Indonesia, SNI) 8664:2018, with a water content of 15.15% w/w, L* values of 35.26, a* value of 28.66, b* value of 59.46, c* value of 66.01, h* value of 64.27°, reducing sugar content of 78.78% and acidity value of 35.56 mL NaOH kg-1. Phytochemical screening showed positive results on alkaloid, flavonoid, phenol and tannin, and the results of GC-MS analysis showed three significant compounds which are hydroxymethylfurfural of 48.26%, levoglucosan of 13.58% and ammonium carbamate of 9.18%.</em></p>

A New Species

AbstractTravassosinema bengalensis n. sp. is described from the hind gut of the spirobolid millipede, Trigoniulus corallinus (Gervais) from West Bengal, India. Females of the new species differ from the only known Indian species, T. travassosi Rao, 1958 by several characters namely tail length, length of oesophagous, size of egg, extension of umbraculum etc. It is very similar to other three species of Travassosinema, T. travassosi, T. thyropygi Hunt, 1996 and T. claudiae Morffe & Hasegawa, 2017 as all of them lack lateral alae and body contraction posterior to vulva. Except T. claudiae, it differs from all other species from millipedes by longest tail length (60% SL) and differs from T. claudiae by shorter oesophagous length and location of vulva.A new method for presentation of morphometric data (in percentage to standard length) in nematode is suggested.On the basis of phylogenetic analysis, it is suggested that umbraculum bearing genera, Indiana, Pulchrocephala should be excluded from the family Travassosinematidae.

A new species of Steinernema is described herein as S. bifurcatum n. sp. It is characterised by the presence of a male gubernaculum that is bifurcate at both proximal and distal ends, a key diagnostic feature. Steinernema bifurcatum n. sp. belongs to the bicornutum group by having two horn-like structures on the labial region of the infective juvenile (IJ). It can be recognised by IJ body diam. = 22 (20-24) μm, pharynx = 114 (102-134) μm, ratio a = 24 (22-25) and D% = 39.7 (33-47). The new species can be further recognised by the male characters of D% = 48 (42-58), and genital papillae = 23 (22 + 1) in number and, for the first generation female, excretory pore = 75.7 (60-108) μm, pharynx = 174 (158-200) μm and tail length = 43.2 (38-60) μm. Steinernema bifurcatum n. sp. is distinguished from all other members of the bicornutum group by the presence of a gubernaculum which is bifurcated at both proximal and distal ends in first generation males. On the basis of genital papillae number (22 + 1) it is close to S. abbasi, S. ceratophorum and S. pakistanense, but can be distinguished by morphometrics of IJ and adults. IJ of S. bifurcatum n. sp. can be differentiated from those of S. ceratophorum and S. pakistanense by the smaller body length of 460-590 μm. Steinernema bifurcatum n. sp. differs from S. abbasi by morphological characters of IJ, male and female stages. The IJ can be distinguished by D% (33-47), body diam. (20-24) μm, b value (3.8-5.6) and pharynx length (102-134) μm. The second generation male differs by GS ratio (0.29-0.45) and the mucronate tail. The first generation female is distinguished by a protruding vulva and no postanal swelling. Analysis of ITS rDNA (824 bp), D2-D3 (880 bp) and mt DNA region (507 bp) sequences confirm that the studied nematode isolate represents a valid new species, the combination of molecular and morphological features indicating that it belongs to Clade IV, the bicornutum group.

Crossbred Pigs

Abstract The purpose of this study was to compare the meat quality and genomic differences between cross-bred commercial pig (CP) and domestic Large Black pig (BP). Seven cross-bred commercial pigs and eight British Large Black pigs were assigned to CP group and BP group, with initial mean body weights of 18.82±1.412 kg for CP group and 23.31±1.935 kg for BP group, P = 0.061, and fed ad libitum. The final BW of the CP at d101 was similar to the BP (130.0±8.16 kg vs. 121.1±2.80 kg, P = 0.132). However, the BP group took 108 days to reach the final BW. The ADG in the CP was higher than BP (1.102±0.0599 kg vs. 0.905±0.0138 kg, P = 0.003). The hot carcass weight of CP was higher (P < 0.01) than BP, but the backfat of BP was higher (P < 0.01) than CP. The a* value of CP was higher (P < 0.05) than BP, and the c* value of CP was tended to be higher (P < 0.10) than BP. However, the h value of BP was higher (P < 0.05) than CP. The longissimus dorsi muscle fat content of BP was higher (P < 0.05) than CP. For the fatty acid composition, the SFA and MUFA of BP were higher (P < 0.05) than CP, but the PUFA of CP was higher (P < 0.05) than BP. The metmyoglobin content of CP was tended to be higher (P < 0.10) than BP. For the meat metabolism, the oxygen consumption of longissimus dorsi muscle of BP was higher (P < 0.01) than CP. The RNA-Seq data showed that the expression of the genes related to lipid metabolism is higher in BP (fold change > 3, P < 0.05). To conclude, BP has higher meat quality, while CP has its advantages in growth performance. And the differences between these two breeds may due to the genomic diversity.

The Right

With the advancement of technology in forestry, the utilization of advanced machines in forest operations has been increasing in the last decades. Due to their high operating costs, it is crucial to select the right machinery, which is mostly done by using productivity analysis. In this study, a productivity estimation model was developed in order to determine the timber volume cut per unit time for a feller-buncher. The Weibull distribution method was used to develop the productivity model. In the study, the model of the theoretical (estimated) volume distributions obtained with the Weibull probability density function was generated. It was found that the c value was 1.96 and the b value was 0.58 (i.e., b is the scale parameter, and c is the shape parameter). The model indicated that the frequency of the volume data had moved away from 0 as the shape parameter of the Weibull distribution increased. Thus, it was revealed that the shape parameter gives preliminary information about the distribution of the volume frequency. The consistency of the measured timber volume with the estimated timber volume strongly indicated that this approach can be effectively used by decision makers as a key tool to predict the productivity of a feller-buncher used in harvesting operations.

This study aims to evaluate the effects of camu-camu powder (CCP), Amazonian berry fruit with documented bioactive properties, physicochemical meat parameters, and the growth kinetics parameters of S. enterica ser. Typhimurium, psychrotrophic bacteria (PSY), and lactic acid bacteria (LAB) in vacuum-packed ground beef. Batches of ground beef were mixed with 0.0%, 2.0%, 3.5%, and 5.0% CCP (w/w), vacuum-packed as 10 g portions, and stored at 5 °C for 16 days. Centesimal composition analyses (only on the initial day), pH, TBARS, and color were quantified on storage days 1, 7, and 15, while PSY and LAB were counted on days 0, 3, 6, 9, 13, and 16. Another experiment was conducted with the same camu-camu doses by inoculating S. enterica ser. Typhimurium microbial kinetic curves were modeled by the Huang growth and Weibull decay models. CCP decreased TBARS in beef from 0.477 to 0.189 mg MDA·kg−1. No significant differences in meat pH between treated and control samples were observed on day 15. CCP addition caused color changes, with color a* value decreases (from 14.45 to 13.44) and color b* value increases (from 17.41 to 21.25), while color L* was not affected. Higher CCP doses caused progressive LAB growth inhibition from 0.596 to 0.349 log CFU·day−1 at 2.0% and 5.0% CCP, respectively. Similarly, PSY growth rates in the treated group were lower (0.79–0.91 log CFU·day−1) compared to the control (1.21 log CFU·day−1). CCP addition at any of the investigated doses produced a steeper S. enterica ser. Typhimurium inactivation during the first cold storage day, represented by Weibull’s concavity α shape parameter, ranged from 0.37 to 0.51, in contrast to 1.24 for the control. At the end of the experiment, however, S. enterica ser. Typhimurium counts in beef containing CCP were not significantly different (p < 0.05) from the control. Although CCP affects bacterial kinetics, it does not protect ground beef against spoilage bacteria and Salmonella to the same degree it does against lipid peroxidation.
