异歧蔗蝗(Hieroglyphus tonkinensis I. Bol.)属直翅目、蝗科(Locustldae),以蝗蝻和成虫取食竹叶,是竹林的一种较重要的害虫。在广东广州和湛江地区一年发生一代,以产于土中的卵块越冬。翌年4月上旬孵化。蝗蝻6—7龄。6月上旬开始羽化,羽化后12—28天交尾,交尾后6—10天产卵。成虫于8月上、中旬—10月中旬相继死亡。已采集的天敌共6种,包括捕食性天敌5种,真菌1种。其中最重要的天敌是蝗霉,6—7龄蝗蝻的自然发病死亡率达52％。用90％敌百虫晶体10,000或20,000倍液、80％敌敌畏乳剂20,000倍液、50％马拉松乳剂10,000倍液对幼蝻进行防治有良好效果。
Hieroglyphus tonkinensis I. Bol. Belongs to the genus Orthoptera and the locust family (Locustldaeae). It takes the locusts and adults to feed bamboo leaves, and is a more important pest in bamboo forests. In Guangzhou, Guangdong and Zhanjiang areas occur a generation a year, to produce eggs in the soil overwintering. The following year hatch in early April. Locust 6-7 years old. Feeding begins in early June, with 12-28 days after eclosion and 6-10 days after mating. Adults in August, mid-October mid-life have been killed. Six natural enemies have been collected, including 5 species of predatory natural enemies and 1 species of fungi. Among the most important natural enemies are locusts, and the natural onset mortality of 6-7-year-old locusts is 52%. With 90% trichlorphon crystal 10,000 or 20,000 times, 80% dichlorvos emulsion 20,000 times, 50% marathon emulsion 10,000 times the prevention and treatment of young children with good results.
