| 摘 要： | 黑缘红瓢虫人工饲料研究结果表明：以草鱼肉、鲜猪肝、夜蛾幼虫粉为主要配方的人工饲料基本满足成虫的营养需要．存活率较高，但平均单头雌虫产卵量较低。各配方饲养的黑缘红瓢虫成虫对朝鲜球坚蚧捕食功能反应均符合模型。以有取食刺激因子的配方成虫对朝鲜球坚蚧作用数据，但各饲料配方饲养的成虫捕食能力(1～31头)都随饲养时间(由第25～290天)的延长而减弱；成虫寻找效应(0．3802～0．0717)随着朝鲜球坚蚧密度(2～10头)的增加而下降，以有取食刺激因子的配方成虫对朝鲜球坚蚧的寻找效应较高，但各配方成虫都随饲养时间的延长而减弱。添加取食刺激因子的人工饲料对提高其成虫的越冬存活率、产卵量、捕食能力和寻找效应有明显促进作用．并且其成虫对饲料的利用率和转化率较高。

| Abstract: | Chilocorus rubidus was artificially fed with five types of diets. The results showed that the mixture of grass carp, pig-liver and powder of Noctidae larvae could met the basic nutrition requirement of Chilocorus rubidus adult. The adult fed with the mixture had a high survival rate, but the females had a relatively low egg production. Preying response of Chilocorus rubidus adults on Didesmococcus koreanus was fitted to HollingII model. Adults fed with No.3 and No.5 diets preyed strongly on Didesmococcus koreanus. However, from 25 to 290 days, their preying capacities (1-31 head) decreased with raising duration. Food-seeking efficiency of Chilocorus rubidus (03802- 00717) declined with increasing the densities of Didesmococcus koreauus (2-10 head). A better efficiency was detected in Chilocorus rubidus adults fed with No.3 and No.5 diets. Addiingpreying stimuli in the adult diet could significantly increase the survival rate from winter, egg number of s, preying ability and food-searching efficiency. |
