捕食性天敵優勢種為四斑月瓢蟲、食蟎瓢蟲、中華草蛉及蜘蛛。The results showed that in the single predator - single prey system of d. catalinae and t. nr. fijiensis, the adult female of d. catalinae had significantly different feeding preference in selecting the stages of t. nr. fijiensis, with the most preference of the eggs followed by larva, protonymph, deutonymph and adult respectively
結果表明：在小黑瓢蟲與紅蜘蛛「單種捕食者?單種獵物」作用系統中，小黑瓢蟲雌成蟲對紅蜘蛛各蟲態的取食呈現選擇性，其中最喜取食卵，其次為幼蟎，最不喜食成蟎。The relationship among searching efficiency ( e ), the prey density ( n ) and the adult ladybird density ( p ) was simulated as e = 0. 3 1 10 / ( 0. 7842 + 0. 000404 n + 0. 21 58 p ) by beddington ' s model e = at / [ 1 + athn + btw ( p - 1 ) ], i. e. the searching efficiency declined when the adult ladybird and the prey densities increased. in the single predator - two preys system, the selective predation of the adult female beetle to both eggs of b. tabaci and t. nr. fijiensis was discussed when two preys coexisted
當兩種獵物共存時，在不同總獵物密度下，測定了捕食者對各獵物的喜好性和轉換行為，分析了兩種獵物共存時，小黑瓢蟲雌成蟲對各獵物的功能反應形式，結果表明:當兩種獵物共存時，小黑瓢蟲雌成蟲對煙粉虱卵在低密度下不表現喜好性，而在中等密度和高密度下表現正喜好性，對紅蜘蛛卵在各密度下均不表現喜好性;對煙粉虱卵的轉換效應會由於總獵物密度的不同而呈現不同的效應，而對紅蜘蛛卵則在各總獵物密度下均呈現負轉換效應。
