| 摘 要： | 为了解东北地区吉林省亚洲飞蝗的生理特性,通过室内饲养实验,对采自吉林省的亚洲飞蝗孵化率、发育历期、体长、体重、头壳宽度、雌雄比和羽化率进行了研究。研究结果表明,试虫孵化率为26.27%,各龄期时间6~7 d,并随环境温度降低有所增长,平均寿命74.52 d。体长生长速度稳定,成虫后雌性平均有翅体长为5.564 cm,雄性为4.968 cm。体重从三龄起生长迅速,成虫后雌性平均体重为1.030 g,雄性为0.848 g。头壳宽度生长也比较稳定,成虫后雌性平均头壳宽度为0.508 cm,雄性为0.526 cm,雌性体形比雄性稍大。试虫雌雄比为1/1.2（雌/雄）,平均羽化率为81.25%。该研究结果有助于更为全面了解吉林省亚洲飞蝗生理特征,为有针对性防治奠定基础。

| Abstract: | This paper focuses on the physiological characteristics of locust(Locusta migratoria migratoria) from Jilin province and reported a laboratory study on hatch rate,mean development duration,body length,weight,head width,sex ratio and adult emerge rate.The results showed that the hatch rate was 26.27%.Each instar lasted about 6-7 days,the instar would increase when temperature dropped,and the average lifetime was 74.52days.The body length grew steadily and the adult females' average body length was 5.564 cm(w... |
