摘要：

为了解氯化胆碱对七星瓢虫成虫生物学特性的影响，筛选饲喂七星瓢虫的人工饲料中较优氯化胆碱剂量，设置5组添加不同剂量氯化胆碱（A、B、C、D、E剂量分别为50、100、150、200、250 mg/100 g）的人工饲料，与豆蚜进行组合饲喂（1 d豆蚜+3 d饲料）七星瓢虫成虫，以不添加氯化胆碱的人工饲料饲养七星瓢虫成虫为对照组(CK)，记录各处理七星瓢虫的产卵量、取食、交配、孵化、存活率。研究结果表明饲养20 d，A、B、C、D、E、CK平均产卵量分别为(286.30±35.14)、(342.4±26.79)、(242.65±25.38)、(241.90±32.24)、(240.45±24.34)、(230.00±23.00)粒/雌，B组产卵量显著高于其他组，其余组间没有显著性差异；各处理七星瓢虫取食频次、交配频次、成虫成活率及卵的孵化率都没有显著性差异。添加100 mg/100 g的氯化胆碱制作的人工饲料与豆蚜组合饲养显著提高了七星瓢虫20日龄的产卵量，对其余生物学指标没有影响。

Abstract:

The study aims to understand the effects of choline chloride on the biological characteristics of Coccinella septempunctata, and screen the optimal dose of choline chloride in artificial diet for feeding ladybird. Five groups were set up with different doses of choline chloride (A, B, C, D, E represent doses of 50, 100, 150, 200, 250 mg/100g, respectively), and fed with soybean aphid (1-dayaphids + 3-day feed), C. septempunctata were fed with artificial diet without choline chloride as control group (CK). The spawning quantity, feeding, mating, hatching and survival rate of each treatment were recorded. In the first 20 days, the average egg production of A, B, C, D, E and CK were (286.30±35.14), (342.4±26.79), (242.65±25.38), (241.90±32.24), (240.45±24.34) and (230.00±23.00) eggs per female, respectively, and the average egg production of group B was significantly higher than those of other groups. There was no significant difference between other groups. There were no significant differences in feeding frequency, mating frequency, adult survival rate and egg hatching rate among different treatments. The combination of artificial diet with 100 mg/100 g choline chloride and bean aphid significantly increased the egg production of ladybird at 20 days of age, but had no effect on other biological indexes.
