中文摘要:为合理预测意大利蝗Calliptamus italicus的种群动态，分别用1%（对照）、4%和7%氮含量的食物饲喂意大利蝗5龄蝗蝻，测定不同氮含量食物处理后意大利蝗5龄蝗蝻的生长速率，羽化后7 d的体长、股节长、胫节长、翅长、翅宽、体重及羽化后1、7、13和19 d的卵巢面积。结果显示，4%氮含量食物处理试虫的生长速率最大，分别较1%和7%氮含量处理的增加了88.02%和109.33%；4%和7%氮含量食物处理后，意大利蝗成虫的后翅宽和体重均显著高于对照；羽化后7 d，不同氮含量食物处理的意大利蝗卵巢面积出现显著差异，羽化后19 d，4%氮含量食物处理的卵巢面积显著高于其他2个处理。表明中等氮含量（4%氮含量）适宜意大利蝗生长。

Abstract:To reasonablly predict the population dynamics of Italian locust Calliptamus italicus, female 5th instar nymphs were fed food containing 1% (CK), 4%, and 7% nitrogen. The growth rate of the 5th instar nymphs was measured, along with body length, femoral length, tibia length, wing length, wing width, and body weight of locusts on the 7th day post-emergence. Additionally, the ovarian area was measured on days 1, 7, 13, and 19 post-emergence following the different nitrogen treatments. Results showed that the growth rate of individuals in the 4% nitrogen group was the highest, increasing by 88.02% and 109.33% compared to the 1% and 7% nitrogen groups, respectively. The hind wing width and body weight of adult locusts in the 4% and 7% nitrogen groups were significantly higher than those in the CK group. On the 7th day post-emergence, the ovarian area of C. italicus differed significantly among the different nitrogen content groups. By the 19th day post-emergence, the ovarian area in the 4% nitrogen group was significantly higher than that in the other two groups. These results indicated that a moderate nitrogen content (4% nitrogen) is suitable for the growth of C. italicus.
