斑点翅果蝇是一种入侵性害虫，已蔓延到世界上许多水果产区。目前，保护水果不受这种昆虫侵害的策略主要是使用杀虫剂，因此生产者需要了解杀虫剂的相对功效和残留活性，以便能够选择有效的处理方法。在半田间生物试验中，对高丛蓝莓带浆果的芽进行处理，然后在施用后的不同时间将其暴露于成虫，结果表明，有机磷、拟除虫菊酯和斯宾辛杀虫剂的新鲜残留物对苍蝇具有很强的初始活性，对果实侵染具有不同程度的残留保护。一种有机除虫菊杀虫剂无效，而新烟碱类杀虫剂醋氨虫被发现有长达5天的活性。施用后的降雨大大降低了某些杀虫剂的防治效果。针对监测陷阱捕获的铃木氏夜蛾，对常规和有机喷雾方案进行了现场规模评估，结果表明，与未经处理的田地相比，这两种管理方式都能提供显著的果实保护，在常规生产的浆果中检测到的幼虫较少。(C) 2013 Elsevier Ltd.版权所有。
Spotted wing drosophila, Drosophila suzukii, is an invasive insect pest that has spread into many fruit production regions of the world. Strategies to protect fruit from infestation by this insect are currently dominated by insecticide applications, so producers need information on relative efficacy and residual activity of insecticides to be able to select effective treatments. Semi-field bioassays in which highbush blueberry shoots with berries were treated then exposed to adult flies at different times after application revealed that fresh residues of organophosphate, pyrethroid, and spinosyn insecticides have strong initial activity on flies, with varying levels of residual protection against fruit infestation. An organic pyrethrum insecticide was not effective, whereas the neonicotinoid insecticide acetamiprid was found to have activity for up to five days. Rainfall after application greatly reduced the level of control achieved by some insecticides. Field-scale evaluation of conventional and organic spray programs initiated in response to capture of D. suzukii flies in monitoring traps indicated that both types of management provide significant fruit protection compared to untreated fields, with less larval detection in the conventionally-produced berries.
