摘要

frontalis (F.)是美国中西部、东北部和东南部地区苗圃生产系统的主要害虫。成虫以植物的叶子为食,这降低了苗圃植物的适销性。可用于保护植物不受frontalis成虫取食损害的方法有限,而且叶面杀虫剂的施用是劳动密集型的。在生长介质中施用系统杀虫剂可以保护植物免受额叶镰刀虫成虫的取食。因此,在2021年和2022年,我们进行了两次实验室和两次温室试验,以确定系统杀虫剂噻虫嗪、呋虫胺、氰虫腈、乙酰甲胺磷、吡虫啉和氟氰菊酯+吡虫啉是否能保护植物免受田间收集的成虫种群的取食。在室内试验中,用上述系统杀虫剂处理含有Itea植物的生长培养基。处理后7 d和25 d,收集叶片,与单株额叶仙花成虫一起放入培养皿中。在温室实验中,茶树植物被放置在观察笼中。将8只成虫放入每个笼中,每个笼中有一株鸢尾植物。在室内试验中,噻虫脒和呋虫胺联合处理,72 h后的成虫死亡率为100%。在温室试验中,噻虫脒、呋虫胺和甲胺磷在系统处理7 d后保护植物不受取食的成虫的侵害。因此,系统施用杀虫剂可以减轻额叶蓟马成虫对苗木的取食损害。

Evaluation of Systemic Insecticides in Protecting Container-Grown Nursery Plants from Damage Caused by Field-Collected Populations of Redheaded Flea Beetle, Systena frontalis (Coleoptera: Chrysomelidae), Adults
Abstract Systena frontalis (F.) is a major insect pest of nursery production systems in the Midwest, Northeast, and Southeast regions of the United States. Adults feed on plant leaves, which reduces salability of nursery-grown plants. There are limited options available to protect plants from S. frontalis adult feeding damage, and foliar insecticide applications are labor intensive. Systemic insecticides applied to the growing medium may protect plants from S. frontalis adult feeding. Consequently, in 2021 and 2022, we conducted two laboratory and two greenhouse experiments to determine if the systemic insecticides thiamethoxam, dinotefuran, cyantraniliprole, acephate, imidacloprid, and cyfluthrin + imidalcoprid protect plants from feeding by field-collected populations of S. frontalis adults. In the laboratory experiments, growing medium containing Itea plants was treated with the aforementioned systemic insecticides. Seven and 25 d after the treatments were applied, leaves were collected and placed into Petri dishes with a single S. frontalis adult. In the greenhouse experiments, Itea plants were placed into observation cages. Eight S. frontalis adults were released into each cage with an Itea plant. In the laboratory experiments, treatments associated with thiamethoxam and dinotefuran resulted in 100% mortality of S. frontalis adults after 72 h. In the greenhouse experiments, thiamethoxam, dinotefuran, and acephate protected plants from S. frontalis adult feeding 7 d after applying the systemic insecticide treatments. Therefore, systemic insecticides can mitigate feeding damage caused by S. frontalis adults on nursery-grown plants.
