摘要

小螟虫（Rhyzopertha dominica）是一种严重的储粮害虫，主要由杀虫剂控制。Spinosad是一种环境友好型生物杀虫剂，对哺乳动物的毒性较低，被认为是一种适合管理多米尼加小蠊的杀虫剂。鉴于spinosad和麦芽糖的结构相似，都含有中性糖结构，假设麦芽糖酶可能水解spinosad，使多米尼加对spinosad产生抗性。本研究采用多株抗spinosad菌株（RdSR）来验证这一假设。

Resistance reduction and cross-resistance of spinosad-resistant Rhyzopertha dominica (Coleoptera: Bostrichidae) and the association between spinosad resistance and maltase activity

The lesser grain borer, Rhyzopertha dominica, is a serious stored-products pest mainly controlled by insecticides. Spinosad, an environmentally friendly biological insecticide with low mammalian toxicity, is considered a suitable candidate for R. dominica management. Given the structural similarity of spinosad and maltose, both containing a neutral sugar structure, it was hypothesized that maltase may hydrolyze spinosad, rendering R. dominica resistant to spinosad. In this study, multiple spinosad-resistant strains (RdSR) were used to test the hypothesis.
