摘要: 为明确替代猎物对日本刀角瓢虫人工饲养的效果,以烟粉虱卵为对照,研究了地中海粉螟卵和米蛾卵对日本刀角瓢虫生长发育及繁殖力的影响。结果表明,饲喂米蛾卵的日本刀角瓢虫存活率为17.16%,发育历期显著延长,雌虫寿命显著缩短;饲喂地中海粉螟卵处理的存活率为77.82%,雌虫寿命显著延长。瓢虫幼虫期和成虫期营养对成虫产卵能力有明显影响:幼虫期饲喂地中海粉螟卵,成虫期分别饲喂米蛾卵和地中海粉螟卵,产卵量极显著降低(分别为64.45粒和53.82粒);幼虫期饲喂地中海粉螟卵,成虫期饲喂烟粉虱卵,产卵量(539.10粒)与对照组无显著差异;幼虫期饲喂烟粉虱卵,成虫期分别饲喂地中海粉螟卵和米蛾卵,产卵量极显著降低(分别为59.30粒和71.38粒)。因此,米蛾卵不适于日本刀角瓢虫饲养,地中海粉螟卵可作为瓢虫幼虫期饲养的替代猎物。

Abstract: Eggs of two alternative prey species Ephestia kuehniella and Corcyra cephalonica were evaluated for effects on development and fecundity of Serangium japonicum (Coleoptera:Coccinellidae), with Bemisia tabaci eggs as the control. Compared with the control, S. japonicum fed C. cephalonica eggs showed lower cumulative survival rate (17.16%), longer developmental time and shorter lifespan. S. japonicum fed E. kuehniella eggs showed no significant difference in cumulative survival rate from the control, but had a longer lifespan. The study also found that feeding different foods during larval and adult stages had a great effect on fecundity. When fed E. kuehniella eggs during larval stage and E. kuehniella or C. cephalonica eggs during adult stage, S. japonicum was of signficantly reduced fecundity (64.45 and 53.82 eggs, respectively). There was no significant difference in fecundity of S. japonicum fed E. kuehniella eggs during larval stage and B. tabaci eggs during adult stage (539.10 eggs) compared with the control. When fed on B. tabaci eggs during larval stage and E. kuehniella or C. cephalonica eggs during adult stage, S. japonicum also exhibited signficantly reduced fecundity (59.30 and 71.38 eggs, respectively). Therefore, C. cephalonica eggs are not suitable for S. japonicum, while E. kuehniella eggs are suitable for rearing the larvae.
