摘要

摘要: 测定了阿维菌素、哒螨灵和阿维菌素炔螨特对黑李上桔全爪螨的室内毒力与田间防效。结果表明:3种药剂对桔全爪螨的室内LC50分别为0.159 6mgL-1、0.975 2mgL-1和23.730 7mgL-1,阿维菌素毒杀效果最好;5.12mgL-1阿维菌素、64.00mgL-1哒螨灵和280.00mgL-1阿维菌素炔螨特对桔全爪螨的田间防治效果均在90.00%以上,杀伤力较好且无药害产生;3种药剂的毒力回归方程b值存在差异,桔全爪螨种群的敏感性分布均匀度为阿维菌素哒螨灵阿维菌素.炔螨特。室内LC50、田间防治效果和毒力回归方程b值可作为黑李上桔全爪螨防控药剂引入的敏感性评价指标。

Abstract: Laboratory toxicity test and field efficacy of three acaricides on Panonychus citri on black plums were conducted.The results showed that the laboratory LC50 of avermectins,pyridaben and avermectins+propargite on P.citri were 0.1596 mgL-1,0.9752 mgL-1 and 23.7307 mgL-1,respectively.Avermectins had the best poisoning effect on the pest.The field efficacy of 5.12 mgL-1 avermectins,64.00 mgL-1 pyridaben or 280.00 mgL-1 avermectins+propargite on P.citri all exceeded 90.00%.The three pesticides all had high lethality to the pest with no phytotoxicity.The b-values of the toxicity regression equations for the three acaricdes differed.The P.citri population sensitivity distributed most evenly with avermectins+propargite,followed by pyridaben and avermectins.It appeared that the laboratory LC50,field efficacy and b-value on the toxicity regression equation could be used as the criteria to evaluate P.citri's sensitivity to acaricides on black plums.
