紫花苜蓿象甲已经成为艾伯塔省紫花苜蓿种子生产商面临的最具挑战性的害虫。紫花苜蓿象甲幼虫使植物落叶,取食降低了产量、质量和林分健康。据估计,在30株12英寸高的植物中,一只幼虫的密度将使每英亩减产约3磅,而在30株16英寸高的植物中,一只幼虫的密度相当于每英亩减产约0.75磅。农民报告说,传统杀虫剂产品的药效有限,并怀疑已经产生了抗药性。切叶蜂是紫花苜蓿种子生产中不可或缺的一部分,因此防治方案必须考虑到传粉者的安全。
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.
