TL;DR
This study evaluates new diets for mass rearing oriental fruit flies in labs, aiming to improve Sterile Insect Technique effectiveness.
Contribution
A new gel-based larval diet and nutrient-rich adult diets are proposed for improved mass rearing of Bactrocera dorsalis.
Findings
The meridic larval diet significantly improved adult body parameters compared to wild counterparts.
Adults reared on meridic diets showed sufficient longevity compared to those given only water.
The formulated diets meet FAO/IAEA/USDA quality standards for tephritid fruit fly mass rearing.
Abstract
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 gel-based meridic larval diet as well as protein and carbohydrate rich adult diets for the rearing of B. dorsalis in laboratory conditions. Proximate analysis was conducted for our formulated rearing diets to determine the content of moisture, protein, fat, carbohydrate, and ash. For our formulated diets, several key biological parameters, including egg hatching rate, pupation rate, pupal weight, adult emergence, adult growth, sex ratio, and…
