Neem leaf dust and a commercial formulation of neem were tested on adult Bactrocera cucurbitae (Coquillett) and Bactrocera dorsalis (Hendel) to determine their effects on the longevity, fecundity and ovarian development. Different combinations of neem leaf dust and a commercial formulation of a neem compound incorporated with sugar solution and adult rearing diets were tested. The Laboratory tests showed that ingestion of neem can significantly reduced the longevity and fertility of both the fly species. Significantly fewer pupae were collected from adults fed on laboratory rearing diet and nimbicidine as water source. Effect of neem treatment on the pupation and subsequent adult emergence of late-instar larvae was negligible. Microscopic observation indicated that the decreased fecundity was due to the block of ovarian development. Experimental results confirmed that neem can be effectively used as a safe alternative insecticide for the control of Bactrocera species.
对印楝叶粉和一种印楝商业制剂进行了测试，以研究其对南瓜实蝇（Coquillett）和橘小实蝇（Hendel）成虫寿命、繁殖力及卵巢发育的影响。测试了印楝叶粉和一种印楝化合物商业制剂与糖溶液及成虫饲养饲料的不同组合。实验室测试表明，摄入印楝可显著降低两种实蝇的寿命和繁殖力。以实验室饲养饲料和印楝素作为水源喂养的成虫所收集到的蛹显著减少。印楝处理对末龄幼虫化蛹及随后成虫羽化的影响可忽略不计。显微镜观察表明，繁殖力下降是由于卵巢发育受阻。实验结果证实，印楝可有效用作防治实蝇的安全替代杀虫剂。
