Bactrocera dorsalis (Hendel) is a notorious insect pest that attacks diverse vegetables and fruits worldwide. The sterile insect technique has been developed as an environmentally friendly and effective control method that depends on the mass production of target flies. Because dietary yeast (protein) and sucrose (carbohydrate) are important in adult diets, yeast:sucrose (Y:S) mixtures are crucial for the mass-rearing of B. dorsalis. In this study, we found adult diets with different ratios of yeast to sucrose-influenced fecundity, and an extremely high or low Y:S ratios significantly decreased egg production of B. dorsalis. Additionally, the maximum oviposition efficiency was realized at dietary yeast to sucrose ratios of 1:1 and 1:3, suggesting their potential use to produce more eggs for the mass production of B. dorsalis. Here, new gel diets having different yeast concentrations (g/L water) were also assessed for rearing B. dorsalis larvae. Gel diets containing 20 g/L yeast led to a higher pupation, pupal weight and adult eclosion rate, and a shorter developmental time than other yeast concentrations. Moreover, the present gel diet also resulted in greater pupal production and adult emergence rates than previously used liquid and solid artificial diets, revealing that it is suitable for rearing B. dorsalis larvae. This research provides a useful reference on artificial diets mixtures for mass rearing B. dorsalis, which is critical for employing the sterile insect technique.

拟南芥（双翅目：蝇科）日粮对成年繁殖力和幼虫发育的评估：采用不育昆虫技术的见解。

Bactrocera dorsalis（Hendel）是一种臭名昭著的害虫，它袭击全世界的各种蔬菜和水果。无菌昆虫技术已经发展成为一种环境友好，有效的控制方法，取决于目标果蝇的大量生产。由于膳食酵母（蛋白质）和蔗糖（碳水化合物）在成人饮食中很重要，因此酵母：蔗糖（Y：S）混合物对于背果双歧杆菌的大量繁殖至关重要。在这项研究中，我们发现成人饮食中酵母与蔗糖影响的生育力比例不同，而Y：S比例过高或过低都会显着降低背果双歧杆菌的产蛋量。另外，在饮食酵母与蔗糖的比例为1：1和1：3时实现了最大产卵效率，表明它们潜在地用于生产更多鸡蛋，以批量生产背果双歧杆菌。这里，还评估了具有不同酵母浓度（g / L水）的新凝胶日粮来饲养背侧双歧杆菌幼虫。与其他酵母菌浓度相比，含有20 g / L酵母的凝胶饮食可导致更高的化up 、,重量和成虫的成虫率，并缩短发育时间。此外，与以前使用的液体和固体人工饮食相比，本凝胶饮食还导致了更高的production产量和成年率，表明它适合饲养背侧双歧杆菌幼虫。这项研究为人工饲养混合背背双歧杆菌的日粮提供了有用的参考，这对于采用无菌昆虫技术至关重要。与其他酵母菌浓度相比，发育时间更短。而且，与以前使用的液体和固体人工饮食相比，目前的凝胶饮食还导致了更高的p产量和成年率，这表明它适合饲养背侧双歧杆菌幼虫。这项研究为人工饲养混合背背双歧杆菌的日粮提供了有用的参考，这对于采用无菌昆虫技术至关重要。与其他酵母菌浓度相比，发育时间更短。此外，与以前使用的液体和固体人工饮食相比，本凝胶饮食还导致了更高的production产量和成年率，表明它适合饲养背侧双歧杆菌幼虫。这项研究为人工饲养混合背背双歧杆菌的日粮提供了有用的参考，这对于采用无菌昆虫技术至关重要。
