摘　　要：束管食螨瓢虫对桔全爪螨成螨、若螨、幼螨的功能反应是ＨｏｌｌｉｎｇⅡ型反应，对卵的反应为Ⅰ型反应；温度、空间异质性不改变功能反应的类型，只影响其参数。捕食者个体间的干扰系数随空间的增大而减小。饥饿程度强烈地影响着捕食行为，成虫在饱食后１．４ｈ内停止捕食。The functional response of Stethorus chengi Sasaji to adults, nymphs and larvae of Panonychus citriMcGregor was shown to be Hollibg Ⅱ type response while that to the egg-Ⅰ type response。Tempetatute and hetetogeneity of 9pace only affected some parameters of the functional reponsewithout changing its type.The interference coefficient between individual predators decreased withthe enlargement of the space. Hunger had a great effect on the predacious behaviour of theladybird.The adult stopped feeding within 1.4 h after satiation.
