摘要：

为探究保幼激素和睾酮对七星瓢虫产卵能力的影响，在人工饲料中添加不同浓度的保幼激素类似物(ZR-515)和睾酮，饲养七星瓢虫成虫，分析其取食频率、交配频率、产卵量和卵的孵化率。结果表明：（1）添加50、5、0.5、0 μL/L的ZR-515（对应处理组J-a、J-b、J-c和J-ck），各组的取食频率和产卵量之间没有显著差异，但J-c组交配频率显著高于J-a、J-b组。（2）添加0.1、0.01、0.001、0 mg/L的睾酮（对应处理组T-a、T-b、T-c和T-ck），各组取食频率、产卵量及卵的孵化率之间没有显著差异，但T-a组交配频率显著高于T-ck组。（3）添加10、1、0.1、0.01、0.001 mg/L睾酮和0.5 μL/L的ZR-515（对应处理组JT-a、JT-b、JT-c、JT-d、JT-e），以只添加0.5 μL/L的ZR-515为对照(JT-ck)，各处理取食频率之间没有显著差异，JT-c组极显著高于JT-e组、显著高于JT-d组，各组产卵量从高到低依次为JT-d[(59.53±9.81)粒]> JT-c[(53.53±9.22)粒]> JT-e[(34.86±7.84)粒]> JT-b[(34.13±6.48)粒]> JT-ck[(31.13±5.17)粒]> JT-a[(7.80±2.58)粒]，JT-d组显著高于JT-a、JT-b、JT-e和JT-ck组，JT-c组显著高于JT-a、JT-e和JT-ck组。研究结果表明，单独添加0.5 μL/L ZR-515或0.1 mg/L睾酮虽能增加七星瓢虫的交配频率，但对产卵量的提升效果不明显。然而，当同时添加0.1 mg/L睾酮和0.5 μL/L ZR-515时，七星瓢虫的交配频率、产卵量和卵的孵化率均显著高于仅添加0.5 μL/L ZR-515的处理组。

Abstract:

Juvenile hormone and testosterone are important insect hormones. In order to understand the effects of juvenile hormone and testosterone on the egg-laying ability of Coccinella septempunctata, in this study, we used artificial diets supplemented with different concentrations of juvenile hormone analog (ZR-515) and testosterone to feed adult ladybird beetles, and analyzed the feeding frequency, mating frequency, egg production and hatching rate of eggs of C. septempunctata in different feeding treatments. The results showed that: (1) there was no significant difference between the feeding frequency and egg production of each group with the addition of ZR-515 at 50, 5, 0.5 and 0 μL/L in J-a, J-b, J-c and J-ck, respectively, and the mating frequency of group J-c was significantly higher than that of groups J-a and J-b. (2) 0.1, 0.01, 0.001, and 0 mg/L testosterone (corresponding to treatment groups T-a, T-b, T-c, and T-ck) were added to the treatments. There were no significant differences in feeding frequency, egg production, and egg hatching rate among the groups, but the mating frequency in the T-a group was significantly higher than that in the T-ck group. (3) Treatments with additions of 10, 1, 0.1, 0.01, 0.001 mg/L of testosterone and 0.5 μL/L ZR-515 (corresponding to treatment groups JT-a, JT-b, JT-c, JT-d, JT-e) were set up with 0.5 μL/L ZR-515 alone as the control (JT-ck). There was no significant difference in feeding frequency among each treatment, while the JT-c group was extremely significantly higher than the JT-e group and significantly higher than the JT-d group. Egg production from high to low was JT-d [(59.53±9.81) eggs]> JT-c [(53.53±9.22) eggs]> JT-e [(34.86±7.84) eggs]> JT-b [(34.13±6.48) eggs]> JT-ck [(31.13±5.17) eggs]> JT-a [(7.80±2.58) eggs], JT-d group was significantly higher than JT-a, JT-b, JT-e, and JT-ck groups, while JT-c group was significantly higher than JT-a, JT-e, and JT-ck groups. The results of this study indicated that supplementing artificial diets with only 0.5  μL/L of the juvenile hormone analog ZR-515 and 0.1 mg/L testosterone increased the mating frequency of C. septempunctata, but did not significantly improve egg production. However, when 0.1 mg/L testosterone and 0.5  μL/L ZR-515 were added together, the mating frequency, egg production, and egg hatching rate were significantly higher than those fed with the diet containing only 0.5 μL/L ZR-515.
