死亡的黃粉蟲肢體呈黑色，有被同類取食的情況發生。In this dissertation, the interactive system of delphastus catalinae ( horn ), its preys and competitor was studied, including comparison between alternative preys and natural prey consumed by d. catalinae ; the system of d. catalinae and its preys ; morphology comparison between d. catalinae and its competitor serangium japonicum chapin ; biology, ecology and predation of s. japonicum ; and also the interspecies competition between d. catalinae and s. japonicum. 1. besides whitefly pests, d. catalinae could also feed on two species of alternative preys : tetranychus nr
Fijiensis和桃蚜myzuspersicae （ sulzer ） ，並在實驗室條件下，以自然獵物煙粉虱bemisiatabaci為對照，研究了替代獵物對小黑瓢蟲的發育、存活、繁殖及對實驗種群增長的綜合影響，結果表明： （ 1 ）小黑瓢蟲以蚜蟲為獵物時，成蟲不會產卵，但可延長成蟲的壽命；以紅蜘蛛為獵物時，成蟲可產卵並可完成整個世代。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。Fijiensis and myzus persicae ( sulzer ). in order to investigate the influence of alternative preys on the ladybird, comparison between its alternative preys and natural prey bemisia tabaci ( gennidius ) was studied in the laboratory, and the results showed that the beetle could not oviposit when feeding exclusively on m. persicae, but the adult longevity was n ' t significantly changed compared with those feeding on natural prey
（ 2 ）小黑瓢蟲分別以三種獵物為食時，均表現為雌蟲的壽命大於雄蟲的壽命， t測驗表明，以蚜蟲為獵物時，雌雄成蟲壽命之間的差異達到極顯著水平；以紅蜘蛛為獵物時，雌雄成蟲壽命之間無顯著差異；以煙粉虱為獵物時，雌雄成蟲壽命之間的差異達到顯著水平。Its developmental zero was 11. 01, and effective temperature constant for one generation was 791. 27 day - degrees
