Assessment of Meridic Gel Larval Diet and Meridic Adult Diet for Mass Rearing of Bactrocera dorsalis (Diptera: Tephritidae)

The oriental fruit fly, Bactrocera dorsalis (Diptera: Tephritidae), is a widespread pest in Bangladesh. Sterile Insect Technique (SIT) offers a solution for effectively suppressing this fruit fly species. However, SIT involves mass rearing of fruit fly species in a laboratory where a standardized artificial rearing diet is crucial for ensuring uniform growth, development, and reproduction. In this study, we assessed efficacy of a new formulated gelbased meridic larval diet as well as protein and carbohydrate rich adult diets for the rearing of B. dorsalis in a laboratory condition. Proximate analysis was conducted for our formulated rearing diets to determine the content of moisture, protein, fat, carbohydrate, and ash. Several key biological parameters, including egg hatching rate, pupation rate, pupal weight, adult emergence, adult growth, sex ratio, and flight capacity, were assessed. Statistical analysis using Tukey box plots revealed a significant improvement in adult body parameters and an increase in longevity for our formulated diets. In addition, our study presents survival analysis using non-parametric Kaplan-Meier estimator and Weibull parametric model. This study shows that integrating our formulated diets into the mass rearing process of B. dorsalis in a laboratory could significantly improve the production of larger and healthier flies on a large scale.

Population dynamics of fruit flies (Diptera: Tephritidae) in a semirural area under subtropical monsoon climate of Bangladesh

Fruit flies belonging to Tephritidae family are highly destructive agricultural pests, posing a significant threat to various fruits and vegetables grown in Bangladesh. A comprehensive year-round survey was conducted at Atomic Energy Research Establishment (AERE) campus located in the central region of Bangladesh. Three types of male lures (methyl eugenol, cue-lure and zingerone) were used to detect and assess the diversity of pest fruit fly species. A total of seventeen species of Tephritidae fruit flies were detected in this survey. The Bactrocera carambolae fruit fly has been discovered for the first time in our survey area, indicating spread of its range towards the north-west region from its previous detection sites (Chattogram and Sylhet Divisions) in Bangladesh. Among the detected pest species, we identified six abundant species: Bactrocera dorsalis, Zeugodacus cucurbitae, Zeugodacus tau, Bactrocera rubigina, Bactrocera zonata, and Dacus longicornis. The most abundant species was the polyphagous fruit pest B. dorsalis, comprising 76.83% of all captured flies. The species Z. cucurbitae was the second most abundant, representing 13.82% of the total trapped flies. The fitted curve to survey data using Gaussian mixture model revealed the existence of overlapped subgroups in the population of B. dorsalis and Z. cucurbitae. In addition, our statistical analysis of the six abundant Tephritidae fruit fly species revealed correlation of population dynamics with several factors including temperature, rainfall, humidity, photoperiod, and fruiting time of host plant species in the selected area.

Effect of different lining paper materials and infusions on oviposition preference of Aedes aegypti (Diptera: Culicidae) gravid mosquitoes

Aedes aegypti (Linnaeus) mosquito is a vector, responsible for increasing global public health concerns due to its rapid geographical spread and increasing vectorial capacity. Understanding the breeding behavior of Ae. aegypti is crucial to control this vector and thereby limiting the spread of diseases. To study this mosquito breeding in the laboratories and ovitraps, different types of lining-papers, surrounding inner surface of a container along with different types of added infusions, are used. Lining-papers serve as surfaces for oviposition and infusions provide the essential environment for nurturing. The types of oviposition surfaces and infusions used in laboratory rearing facilities or ovitraps influence oviposition preference, changing the breeding behavior of Ae. aegypti gravid mosquitoes. This study presents a comparative study on oviposition preferences for six different types of lining-papers and six different types of infusions in a bioassay cage. ANOVA analysis shows a significant effect on oviposition preference of different types of lining-papers that served as oviposition surfaces. The highest oviposition activity was observed for the agri seed germination paper-75 lining-paper when normal tap water infusion was used. Likewise, statistical analysis shows that when a plain printing offset paper 80 GSM lining-paper was used, a highly statistically significant effect on oviposition preference is observed for different types of infusions used in the oviposition cups.
