摘要: 在伊朗, 麦扁盾蝽Eurygaster integriceps是小麦和大麦上的主要害虫。新烟碱类杀虫剂是一类具有较强活性的杀虫剂, 对刺吸式口器害虫具有良好的效果。本研究应用触杀和熏蒸两种生测方法测定了4种新烟碱类杀虫剂(噻虫嗪、吡虫啉、呋虫胺和啶虫咪)对麦扁盾蝽3龄若虫和成虫的毒效。触杀法生测结果显示, 各杀虫剂对麦扁盾蝽没有强烈的触杀活性, 但是在高浓度下(5 000 mg/L a. i.), 可见较高的死亡率。熏蒸法生测结果显示, 所有杀虫剂对麦扁盾蝽的若虫和成虫均有较好的毒性。结果提示应用熏蒸方法可能是治理这一重要害虫的新方法。

Abstract:  Eurygaster integriceps is a key pest of wheat and barley in Iran. Neonicotinoid insecticides, a strong group of insecticides, have good effect on sucking pests. In this study, effects of four neonicotinods (thiametoxam, imidacloprid, dinotefuran and acetamiprid) on 3rd nymphs and adults of E. integriceps via two methods (contact and chemigation) were investigated. Although tested insecticides had no strong effect on E. integriceps in contact method and acceptable mortality was seen at very high concentration (5 000 mg/L a. i.), all insecticides had acceptable toxicity to nymphs and adults through chemigation bioassay. According to current results, using chemigation can be a novel method for management of this important pest.
