摘要
异色瓢虫为重要的捕食性天敌昆虫,在生长发育过程中常取食一些花粉或花蜜作为食物.为了明确花粉蜜源对异色瓢虫生物学特性的影响,设置花粉+蚜虫、花粉、蚜虫、清水4个处理,主要研究了花粉蜜源对异色瓢虫成虫产卵量、寿命、存活率、幼虫捕食率、发育历期等指标的影响.结果表明:补充花粉蜜源可显著提高该虫的成虫产卵量、寿命以及存活率.但单独以其为食物,成虫产卵量与取食蚜虫的处理相比显著降低,表明蜜源不能替代蚜虫为异色瓢虫的繁殖提供必要的营养.花粉蜜源对该虫的幼虫捕食量、发育历期无显著影响.花粉蜜源对异色瓢虫成虫有显著影响,但对幼虫影响不显著.
Abstract
As an important predatory insect,Harmonia axyridis often feeds on some pollen or nectar during its growth and development.In order to clear the effects of pollen and nectar sources on the biological characteris-tics of H.axyridis,four treatments including pollen+aphid,aphid,pollen and water were set up to study the number of eggs,life span,survival rate of its adult,predation rate of its larval and developmental duration.The results showed that the supplement of pollen and nectar had significant effects on the number of egg,longevity and survival rate.However,the the number of egg fed on the pollen alone was significantly lower than that of the aphid-feeding treatments,indicating that nectar could not replace aphids for the reproduction of H.axyridis.Pollen and nectar sources had no significant effect on larval development duration and predation.The pollen and nectar source has a significant impact on the adults,but has no significant effect on larvae.
