吉林市地锦斑蛾初步研究

通过现场观察和室内饲养的方法, 对地锦斑蛾Illiberis consimilis Leech, 1898的形态及周年发生规律进行了调查研究。结果表明, 地锦斑蛾在吉林市1年发生1代, 以茧内蛹在地锦植株下落叶层中越冬。每年3月末成虫羽化, 于4月上旬产卵于地锦枝蔓表皮、芽眼、分枝及卷须上, 4月中旬至5月上旬卵孵化, 幼虫取食五叶地锦叶片、山葡萄叶片和果穗, 将叶片吃成孔洞或吃光。本文对地锦斑蛾提出了防治建议。

Primary research on Illiberis consimilis in Jilin City

Combining field investigation and indoor feeding, the morphological and biological characteristics as well as the occurrence of Parthenocissus quinquefolia spot moth, Illiberis consimilis Leech, in Jilin were investigated. The results showed that P. quinquefolia spot moth only had one generation each year in Jilin and overwintered beneath the litter layer of P. quinquefolia as pupae. At the end of March, the adults emerged and laid eggs on the bud, leaves, branches and tendrils of P. quinquefolia in early April. When the larvae came out during mid-April and early May, they fed on the P. quinquefolia leaves, grape leaves and clusters and caused great damages. Controlling measures were also put forward.
