Abstract

The Mexican bean weevil Zabrotes subfasciatus (Boheman) (Coleoptera, Chrysomelidae, Bruchinae) has become one of the main pests of common bean (Phaseolus vulgaris L.) (Fabaceae) worldwide. The association of resistant bean varieties with botanical insecticides has a great potential for controlling the pest, but it has been little studied so far. Therefore, the present study aimed at selecting a botanical insecticide and evaluating its combined effect with an arcelin-bearing common bean resistant genotype against Z. subfasciatus. We evaluated three botanical insecticides, the rotenone-based Roteline® and the neem-based NeemSeto® and NeemPro®, on the development of the insect. NeemPro® was the most effective, presenting ovicidal effect and prolonging egg-to-adult period, being selected for the following bioassay. Then we evaluated the effect of NeemPro® combined with the resistant common bean genotype IAC 818 (RAZ-59) on some biological parameters of the pest. The most severe effects on Z. subfasciatus were caused by the resistant genotype. However, significant effects in some parameters of the pest were also verified for the botanical insecticide and for its combination with this resistance type/trait in the conditions of the experiment.

寄主抗药与植物性杀虫剂联合防治蚕豆筋膜小蠹(鞘翅目，金蛉科，Bruchinae)

墨西哥豆象(鞘翅目，金花蝇科，Bruchinae)已成为世界范围内普通豆(Phaseolus vulgaris L.)主要害虫之一。抗性大豆品种与植物性杀虫剂的结合具有很大的防治潜力，但迄今为止研究甚少。因此，本研究旨在选择一种植物性杀虫剂，并评价其与一种含arcelin的普通豆抗性基因型联合防治筋膜下叶卷虫的效果。我们评估了三种植物性杀虫剂，鱼藤酮类杀虫剂Roteline®和NeemSeto®和NeemPro®对昆虫发育的影响。NeemPro®是最有效的，具有杀卵效果，延长卵到成虫的时间，被选择用于以下生物试验。在此基础上，评价了NeemPro®与抗病普通豆基因型IAC 818 (RAZ-59)联用对该害虫部分生物学参数的影响。对筋膜下恙虫病影响最大的是抗性基因型。然而，在实验条件下，植物性杀虫剂及其与该抗性类型/性状的组合对害虫的某些参数也有显著影响。
