南方小花蝽液体人工饲料的饲养效果评价

Evaluation of an artificial liquid diet of Orius similis Zheng (Hemiptera:Anthocoridae)

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。

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 ...
