摘要:

小贯小绿叶蝉(Empoasca onukii Matsuda)是茶园主要害虫之一,为筛选出用量少、效果好的杀虫剂来综合防控小贯小绿叶蝉,本研究选取6种单剂和6种混剂,每种单剂设置5个浓度梯度,每种混剂的每个配置比例设置3个处理浓度,采用刺吸电位图谱(electrical penetration graph, EPG)技术分析小贯小绿叶蝉的刺探行为。结果表明,单剂效果为22%氟啶虫胺腈悬浮剂>50 g·L-1双丙环虫酯可分散液剂>70%吡虫啉水分散粒剂>10%氟啶虫酰胺水分散粒剂>25 g·L-1高效氯氟氰菊酯乳油>30%噻虫嗪悬浮剂。不同比例混剂的效果不同,30%噻虫嗪悬浮剂+50 g·L-1双丙环虫酯可分散液剂混剂各比例对小贯小绿叶蝉取食波型影响较大,30%噻虫嗪悬浮剂+70%吡虫啉水分散粒剂混剂对小贯小绿叶蝉的取食波型影响较小。混剂处理后小贯小绿叶蝉的刺探次数、刺探总持续时间、E波持续时间都均低于各个单剂处理。以上结果说明,混配制剂对小贯小绿叶蝉刺探行为的影响优于单剂,可应用于茶园小贯小绿叶蝉的防控。

Abstract:

Empoasca onukii Matsuda is one of the main pests in tea garden. In order to screen out the insecticides with less dosage and better effect for comprehensive control of E.onukii, in this study, 6 single and 6 mixed agents were selected, each single agent was set with 5 concentration gradients, and each mixed agent’s configuration ratio was set with 3 treatment concentrations, and electrical penetration graph (EPG) technique was used to analyze the sucking behavior of E. onukii. The results showed that the order of effect of single agent was as follows: sulfoxaflor 22% SC>afidopyropen 50 g·L-1 DC>imidacloprid 70% WG>flonicamid 10% WG>lambda-cyhalothrin 25 g·L-1 EC>thiamethoxam 30% SC. The effects of different proportions of the mixture were different, and the mixture of thiamethoxam 30% SC+afidopyropen 50 g·L-1 DC had a greater effect on the feeding waveform of E. onukii, the mixture of thiamethoxam 30% SC+imidacloprid 70% WG had little effect on the feeding waveform of E. onukii. The sucking times, the total duration of sucking and E wave duration in mixture treatment were all lower than that of every single agent treatment. The results showed that the influence of mixed agents on sucking behaviors was better than single agent, and it could be used for controlling E. onukii in tea garden.
