摘    要:为评价一种液体人工饲料的饲养效果,以棉蚜饲养南方小花蝽作对照,用液体人工饲料连续两代饲养南方小花蝽若虫和成虫,对南方小花蝽各生长阶段的生长和发育指标进行调查。结果显示:用人工饲料饲养的南方小花蝽若虫历期(22~23天)与对照组(21天)之间不存在显著差异,说明液体人工饲料可以很好的满足南方小花蝽若虫生长的营养要求。然而,用棉蚜饲养的对照组南方小花蝽成虫获得率可达到63%,而人工饲料组连续两代的成虫获得率分别仅为45% 和43%。取食人工饲料的南方小花蝽成虫,在产卵前期、产卵量及寿命方面与对照组都没有显著差异,仅在产卵期方面有着显著差异,人工饲料组小花蝽的产卵期为13~16天,而对照组小花蝽的产卵期可达20天,说明液体人工饲料也可以很好的满足南方小花蝽成虫生殖发育的营养要求。

关 键 词:南方小花蝽  液体人工饲料  大规模饲养  生物防治  生长发育  繁殖

Abstract:To evaluate an artificial liquid diet of Orius similis Zheng,the nymph and adult of O.similis were fed on the artificial diet for two generations continuously using cotton aphids as the control,and their developmental and reproductive indexes at different stages were investigated.The results showed that the durations(22-23 days)of the two consecutive generations of O.similis were not significantly different from that of the control(21 days),which suggested that the diet could well meet the nutritional need of the nymph of O.similis for growth and development.However,the obtainable rate of the adult of O.similis fed on the cotton aphids could achieve 63%,which was prominently greater than those of the two consecutive generations of O.similis fed on the artificial liquid diet,which were 45% and 43%,respectively.There were no significant differences in the period of pre-oviposition,the fecundity and longevity of the adult of O.similis between the treatments and the control.But the significant difference was observed in the period of oviposition between the treatments and the control,which are about 13-16 days for the treatments and 20 days for the control,respectively.These results suggested that the artificial liquid diet could also well meet the nutritional need of adult O.similis for reproduction.
Keywords:Orius similis  artificial liquid diet  mass rearing  biological control  growth and development  reproduction
