实验证明,虚伪钝绥螨对猎物的寻觅行为是受猎物的某种化学信息物所影响。雌、雄猎物产生的信息物对其引诱力无差异。当虚伪钝绥螨长期取食某种猎物,对这种猎物的信息物反应特别敏感。当改用其他猎物饲养两代以上后,其趋性反应也随之改变,对前者反应减弱,对后者增强,说明该螨的食性有较大的适应能力和可塑性。用甲醇对硃砂叶螨雌成螨,及其所排出的丝和粪分别提取,虚伪钝绥螨对叶螨粪的提取液反应最强烈。
Experiments show that hypnotic Amblyseius mites search for prey behavior is affected by some chemical information of prey. There is no difference in the seduction of information produced by female and male prey. Long-term feeding of a prey to the pseudo-Asiatic mite is particularly sensitive to the informational response of such prey. When switched to other prey for more than two generations, the trend of its response will also change, the former reaction weakened, the latter enhanced, indicating that the mite feeding adaptability and plasticity. The carotid beetle was extracted from the female adult mites of Tetranychus cinnabarinus with methanol and the silk and feces excreted respectively.
