苜蓿象鼻虫已成为艾伯塔省苜蓿种子生产商最具挑战性的害虫。苜蓿象鼻虫幼虫会使植物落叶,它们的取食会降低产量、质量和林分健康状况。据估计,30 棵 12 英寸高的植物中如果有 1 个幼虫,每英亩产量就会减少约 3 磅,而 30 棵 16 英寸高的植物中如果有 1 个幼虫,则每英亩产量会减少约 0.75 磅。农民报告传统杀虫剂产品的功效有限,并怀疑已经产生了抗药性。切叶蜂是苜蓿种子生产的一个组成部分,因此控制方案必须考虑传粉媒介的安全。
英文摘要
Alfalfa weevil has become the most challenging pest for Alberta's alfalfa seed producers. Alfalfa weevil larvae defoliate plants and their feeding reduces yield, quality, and stand health. A density of one larva in thirty twelve-inch-tall plants has been estimated to reduce yield by about 3 lb per acre and one larva in thirty sixteen-inch-tall plants translates to a loss of approximately 0.75 lb per acre. Farmers report limited efficacy from conventional insecticide products and suspect resistance has developed. Leaf-cutter bees are an integral part of alfalfa seed production, so control options must regard pollinator safety.
