黄守瓜、黄足黑守瓜成虫对瓜类苗期危害的研究

A Study of Aulacophara femoralis,A.lewisll Imago on The Seedlings Damage of Melon

报道了瓜类—黄瓜 (Cucumis sativus)、丝瓜 (L uffa cylindrica,)、南瓜 (Cucurbitamoschata)、冬瓜 (Benincasa hispida)、苦瓜 (Monordica charantia)的重要害虫黄守瓜 (Aula-cophara femoralis)、黄足黑守瓜 (A.lewisll)在瓜类苗期的危害情况 .结果表明 ,黄守瓜、黄足黑守瓜均不取食苦瓜叶 ;黄足黑守瓜只取食丝瓜叶 ;黄守瓜最喜吃黄瓜叶 ,其次是南瓜叶和冬瓜叶 ,对丝瓜叶的取食量较少 .两种害虫随时间的推移和虫量的增加其取食量加大 .统计分析表明 :黄守瓜的虫量如每株达 1头或超过 1头 ,则黄瓜苗难以成活 ,3～ 4d瓜苗被毁 ;南瓜苗、丝瓜苗、冬瓜苗生长不正常 .黄足黑守瓜的虫量如每株达 1头或超过 1头 ,则丝瓜苗也难以成活 .

This paper presents the damage condition of melon′s ( Cumumis sativuslinn, Luffa cylindrica, cucurbita moschata, Benincasa hispida, Momordica charantia L.) major pest Aulacophara femoralis,A.lewisll during the seedlings stage. Results show that Aulacophara femoralis and A.lewisll do not eat leaves of Momordica charantia L; A.lewisll only eat the leaves of Luffa cylindrica; Aulacophara femoralis is the fondest of eating the leaves of Cumumis sativuslinn ,the leaves of cucurbita moschata and Benincasa hispida secondly,the leaves of Luffa cylindrica least. Eating quantity of two types of pest increases continuously with time going by and population of pest raising. Statistic analysis show that the seedlings are difficult to survive and will be damaged in 3~4 day; the seedligs of Luffa cylindrica and cucurbita moschata will be abnormal to grow, if the amount of Aulacophara femoralis reaches one or more per seedling; it also shows that the seedlings of Luffa cylindrica are difficult to survive,if the amount of A.lewisll reaches one or more per seedling.
