The pine weevil (Hylobius abietis) is a major forest regeneration pest causing high levels of seedling mortality and economic losses. Current management relies on silviculture, stem coatings and insecticides. Here we evaluated for the first time the effects of Bacillus thuringiensis (Bt) strains on H. abietis adults: two producing the Coleoptera‐targeted toxins Cry3Aa (Bt tenebrionis NB‐176) and Cry8Da (Bt galleriae SDS‐502), and one producing the Diptera‐targeted Cry10A (Bt israelensis AM65‐52). Choice and nonchoice assays using individual and mixtures of Bt formulations, containing these strains respectively, were conducted.

一种主要的森林害虫，即象鼻虫松叶象鼻虫（Hylobius abietis）比鞘翅目针对苏云金芽胞杆菌的菌株更容易受到双翅目的侵害。

松象鼻虫（Hylobius abietis）是一种主要的森林更新害虫，会导致高水平的幼苗死亡和经济损失。目前的管理依靠造林，茎干涂层和杀虫剂。在这里，我们首次评估了苏云金芽孢杆菌（Bt）菌株对姬松茸成虫的影响：两个产生鞘翅目靶向毒素Cry3Aa（Bt tenebrionis NB-176）和Cry8Da（Bt galleriae SDS-502）。以双翅目为目标的Cry10A（Bt以色列AM65-52）。使用Bt的个体和混合物进行选择和非选择分析 进行了分别包含这些菌株的制剂。
