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。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.
