藿香蓟和假臭草对柑橘木虱种群发展的影响

果园生草是病虫生态控制中的重要手段之一,藿香蓟可为柑橘害螨的自然天敌捕食螨提供栖息和繁殖场所,在橘园内被大量保留和引种。本文测试了重要柑橘害虫柑橘木虱成虫对藿香蓟的选择偏好、栖居于藿香蓟上的存活时长,以及藿香蓟存在条件下农药对木虱成虫防治效果的影响。结果显示：在无柑橘时,木虱成虫对藿香蓟和假臭草的选择比率分别为31.52%和16.22%,两者差异极显著,而在有柑橘同时存在的条件下,木虱成虫对藿香蓟和假臭草也分别有1.24%和0.83%的选择比率,但两者差异不显著;而木虱在藿香蓟上存活最长达49 d,在假臭草上仅12 d;在柑橘枝条上喷施1.8%阿维菌素乳油90 mg/L 11 d后,若无藿香蓟...

Summary:果园生草是病虫生态控制中的重要手段之一,藿香蓟可为柑橘害螨的自然天敌捕食螨提供栖息和繁殖场所,在橘园内被大量保留和引种。本文测试了重要柑橘害虫柑橘木虱成虫对藿香蓟的选择偏好、栖居于藿香蓟上的存活时长,以及藿香蓟存在条件下农药对木虱成虫防治效果的影响。结果显示：在无柑橘时,木虱成虫对藿香蓟和假臭草的选择比率分别为31.52%和16.22%,两者差异极显著,而在有柑橘同时存在的条件下,木虱成虫对藿香蓟和假臭草也分别有1.24%和0.83%的选择比率,但两者差异不显著;而木虱在藿香蓟上存活最长达49 d,在假臭草上仅12 d;在柑橘枝条上喷施1.8%阿维菌素乳油90 mg/L 11 d后,若无藿香蓟同时存在,木虱成虫死亡率为79.49%;若有藿香蓟同时存在,木虱成虫死亡率仅为42.76%,两者差异极显著。结果表明,藿香蓟对农药防治柑橘木虱的效果存在一定的干扰作用,对木虱种群的发展有较大的影响。

Conservation of weeds in orchard is one of the important tactics for the ecological control of pests and diseases. Ageratum conyzoides has been retained or planted in citrus orchards as it habits predatory mites,the natural enemies of phytophagous mites of citrus. In this paper we assessed the selection preferences and the survival time of citrus psylla,Diaphorina citri on Ageratum conyzoides and Eupatorium catarium,and its mortality after pesticide treatment in the conditions of absence of A. conyzoides. The results indicated that,the selection ratio
