General esterases of oriental migratory locust collected from the four locations were compared . general esterases were most concentrated in the thorax and abdomen , which showed 46 . 1 % and 36 . 1 % of total esterase activity in females , and 42 . 7 and 36 . 0 % in males , when using - na as substrate 东亚飞蝗中酷酶活性主要集中在胸部和腹部，水解a ~ na的酷酶活性在雌性东亚飞蝗中分别有46 . 1 %和36 . 1 %集中在胸部和腹部，在雄性中分别为42 . 7 %和36 % 。
Among these factors the effects of the atlantic subtropical high on locusts occurrence are mainly caused by sub - aerial temperature that is affected by the atlantic subtropical high in autumn and winter when the locusts live through and incubate ; there fore the occurrence , the development and the suffering of the locust as well as it ' s a - mount of eggs and imagos are impacted 其中大西洋副热带高压对我国东亚飞蝗发生的影响主要是通过影响秋冬季节蝗卵的孵化和越冬期间的地面温度，从而影响蝗卵基数和孵化为成虫的数量，进而影响着我国东亚飞蝗发生、发展和危害情况的变化。
