摘要
在室内26±2℃,RH=50±10%,L∶D=16h∶8h环境下,使用白色、红色、蓝色、紫色、黑色5种棉花作为孟氏隐唇瓢虫Cryptolaemus montrouzieri Mulsant的产卵基质供其产卵,研究该瓢虫对产卵基质的颜色偏好性。结果表明连续10日内该瓢虫在红色棉花上的产卵次数和总产卵量最多,产卵次数与总产卵量表现出一定的线性关系。该结果对了解环境条件对孟氏隐唇瓢虫的生长发育、繁殖的影响,为天敌瓢虫人工扩繁,卵的收集提供了理论依据。
The color preference of Cryptolaemus montrouzieri on substrates was investigated with providing 5 colors cotton substrates：white,red,blue,purple,and black,for oviposition selection at 26±2℃,50±10% RH and a photoperiod of 16 h L：8 h D indoor environment.The results suggested that the oviposition times and total number of eggs laid on red color cotton by C.montrouzieri in ten days was much more than that on the other color cotton respectively,and the oviposition times and total number of eggs laid on color cottons existed linear relationships.Our findings would be as theoretical basis for eggs collected of the ladybird in mass artificial rearing.
