Adult Diet

The Guava fruit fly Bactrocera correcta is serious pest attacking Dragon fruit (Hylocereus undatus and Hylocereus polyrhizus ). The study on the impact of (i) Protein in adult diet on sexual maturity of Guava fruit fly; (ii) Methyl eugenol (ME) feeding on sterilized male of Guava fruit fly; and (iii) Longevity of sterilized males and females feeding on different diets. All those trials were conducted for both sterile males and laboratory flies reared at Plant Protection Research Institute, Hanoi, Viet Nam. The initial results showed that the first age of sexual maturation of laboratory reared females are 7 days old and 8 days old when fed on a mix diet of hydrolyzed yeast: sugar (1:4) and only sugar diet, respectively. Four days after emergence, females on hydrolyzed yeast fed diet died. The highest percentage of mating for the period of 20 first days after emergence was recorded 7.19% at 11 days old of flies fed on sugar; 40.08% at 10 days old of flies fed on hydrolyzed yeast and sugar. The longevity of sterilized males was 30.7 days, 28.1 days and 3.2 days as feeding on mix of hydrolyzed yeast: sugar, sugar only and hydrolyzed yeast alone, respectively. Likewise, the longevity of females was 32.5 days on hydrolyzed yeast: sugar diet, 30.5 days on sugar only diet and 3.7 days on hydrolyzed yeast only diet. The percentage of sterile males feeding on ME at 3 days old was only 5% and reached 40% at 8 days old with feeding times of 44 seconds and 4 minutes 27 seconds respectively.

The oriental fruit fly Bactocera dorsalis (Hendel) is an important pest of snake fruit (Salacca zalacca) in Sleman District. Due to the high level of damage by the fruit flies, it is necessary to do. The aim of this research was to find out suitable fruit traps, by testing the oviposition preferences of the fruit flies in the orchard to lay eggs on several types of fruit. The research was done in snake fruit orchard located at Sleman Yogyakarta and owned by farmers, while the Lab works were done at the Laboratory of Entomology, Department of Plant Protection, Faculty of Agriculture, Universitas Gadjah Mada. All researches were done between April-June 2019. Guava (Psidium guajava), watery rose apples (Syzygium aqueum), starfruit (Averrhoa carambolae), and snake fruit (Salacca zalacca) were used as trap crops. Each fruit, with the same maturity level, was hung 1.5 m above the ground for 4 days with 12 days total trapping at intervals of 3 times. After the test, each fruit was taken and the insects in it were reared in the laboratory. The number of pupae and flies that emerged from each fruit was counted and compared. The results showed that in the orchard 1 as well as  2, of guava fruit produced the highest number of (151 pupae) followed by salak (94 pupae), star fruit (83 pupae), and water guava (2 pupae). The finding of seeds shows that guava fruit is the most suitable host for the fruit flies to be used in the trapping, followed by star fruit and watery guava.

Maxent Modeling

Maximum entropy (MaxEnt) modeling was used to predict impact of climate change on habitat suitability of guava fruit fly, Bactrocera correcta in India. It is a polyphagus pest on a wide variety of fruit crops. Future prediction of potential habitat of B.correcta was done for the year 2050 and 2070 with RCP 2.6, RCP 4.5, RCP 6.0 and RCP 8.5 climate scenarios. The model preformed better than random with an average test AUC value of 0.75 of 100 replicate tests run. Under the present and future climatic conditions, the model predicted high habitat suitable category for B. correcta in the areas of south-western coastal (Kerala, Karnataka, Tamilnadu, Maharashtra and Gujarat) part of India by 2050 and 2070. Presently absolute unsuitable areas of Indian sub-continent are projected to be slightly suitable for B. correcta by 2070 due to increase in temperature coupled with decrease in cold stress. The predictive modeling approach presented here provides an outline for future risk of B.correcta in India under climate change scenarios, which can be used for its better management strategies.

Ethyl Hexadecanoate

The guava fruit fly, Bactrocera correcta, is one of the major pests affecting mango (Mangifera indica) and guava (Psidium guajava) production in China. The compound β-caryophyllene was identified from the rectal gland extracts of wild B. correcta males and was demonstrated to be a more specific and potent male lure than methyl eugenol (ME) for B. correcta. In order to find potential additional pheromone attractants for the monitoring and mass-trapping of this fruit fly, a series of chemical and behavioral assays were conducted in this study. Ten compounds were identified from the rectal glands of virgin B. correcta females. These compounds consisted of five major compounds (i.e., ethyl dodecanoate, ethyl tetradecanoate, ethyl (E)-9-hexadecenoate, ethyl hexadecanoate, and ethyl (Z)-9-octadecenoate) in high quantities, and other compounds (i.e., octanal, N-(3-methylbutyl) acetamide, (Z)-9-tricosene, ethyl octadecanoate, and ethyl eicosanoate) in trace amounts, while virtually no compounds were found in male rectal glands. The bioassays indicate that female rectal gland extracts are attractive to virgin females and males. Furthermore, a cyclical production of the five major compounds was found, recurring at roughly 10-d intervals with peaks in 10–13-, 25-, and 35-d-old females. Collectively, these results will contribute to the understanding of pheromone communication in B. correcta and may provide important information for improving existing monitoring and control methods for this pest.

Abstract Background The peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae), is a serious polyphagous pest of fruits and vegetables. Chemical management of B. zonata in fruits results in toxic residues that have adverse health effects on consumers resulting in increased demand for eco-friendly approaches. Laboratory bioassay was conducted to determine the pathogenicity of fungal and bacterial biopesticides against B. zonata. Results The pathogenicity of all tested bioinsecticides revealed that the maximum concentration (1 × 108 CFU ml−1) of Metarhizium anisopliae, Beauveria bassiana, Lecanicillium lecanii and Bacillus thuringiensis caused 95.8–100%, 95.9–97.9%, 32.7–39.6%, and 20.0–22.4% mortality in B. zonata, respectively at 7 d post-application interval (PAI) as compared to mortality demonstrated by the same concentration at 5 d PAI. All tested microbial insecticides induced statistically similar mortality in both male and female B. zonata at each concentration for the same PAI. Correlation coefficient (r) values reveal that concentrations of each microbial insecticide had a high positive correlation with mortalities of male and female B. zonata. Regression parameters reveal that concentrations of tested microbial insecticides had significant linear relationship with and explained significant variability in B. zonata mortality (P < 0.05). Results also revealed that M. anisopliae was proved more pathogenic to males and females of B. zonata demonstrating the least LC50 values (5.48 × 103, and 6.17 × 103 CFU ml−1, respectively) 7 d post-application intervals, followed by B. bassiana which explained LC50 value of 1.14 × 104 CFU and 1.15 × 105 CFU ml−1 for B. zonata males and females, respectively, at the same period of application, but less than that of L. lecanii (2.77 × 109 and 1.43 × 109 CFU ml−1) and then B. thuringiensis (3.40 × 1010 and 1.39 × 1010 CFU ml−1) for the males and females, respectively, at 7 d PAIs. Conclusion Metarhizium anisopliae incorporated adult diet was proved more effective against B. zonata, followed by B. bassiana, L. lecanii, and B. thuringiensis. Hence, M. anisopliae can be recommended for incorporating in bait-traps to develop attract-and-kill technology for B. zonata.
