在实验室观察了白虫小茧蜂的产卵行为,从化学及物理的角度探讨了寄主因素对白虫小茧蜂产卵的影响。这些寄主因素包括寻主利它素、寄主表皮的化学物质,显微结构和柔软性。实验表明:寄主表皮的柔软性是影响该小茧蜂产卵的关键因素。寻主利它素、寄主表皮的化学物质和结构均对产卵没有影响。 In the laboratory, the behavior of spider beetle eggs was investigated. The effects of host factors on spawning of the spider beetle were studied both chemically and physically. These host factors include predominantly tropicin, chemicals in the host epidermis, microstructure and softness. Experiments show that the softness of the host epidermis is the key factor that affects the ovipositing of the. Finding primary aliskins, chemical substances and structures of the host epidermis have no effect on spawning.
