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。 Five cottons of white, red, blue, purple and black were used as Cryptolaemus montrouzieri Mulsant in an environment of 26 ± 2 ° C, RH = 50 ± 10% and L: D = 16 h: The egg substrate was used for oviposition and the color preference of the ladybug on the oviposit matrix was studied. The results showed that the number of spawning and total fecundity of ladybug on red cotton was the highest in 10 consecutive days. The number of spawning and total fecundity showed a certain linear relationship. The results of understanding the environmental conditions on the growth and reproduction of the ladybug Lepidoptera, for artificial propagation of natural enemies ladybugs, eggs provide a theoretical basis.
