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。
