摘要
玉米旋心虫（ApopnyliaflavoviyensFairmaire）在豫西主要分布于海拔500m以上的丘陵浅山区。1a发生1代，幼虫危害盛期在6月至7月中旬末，主要造成玉米枯心苗，呈分蘖丛生的畸形株，多不抽穗而致绝收。发现成虫寄主有白苏、紫苏和冬凌草3种。适时早播和轮作倒茬是减轻危害的经济有效措施；用甲基异柳磷毒土围苗等药杀幼虫是田间防治控制危害的重要手段。
Apopnylia flavoviyens is distributed mainly over the hilly countries with elevations of 500 metres in western Henan Province. It occures one generation in one year. The super period of larvae harm ness is in the time from the last tenday peried of June to the second tenday period of July. It causes mainly maize heart-leaf blight, rosette plant, and having no harvest even. It has been found that Perilla frutescens (L. ) Britto, P. frutescens var. arguta (Benth.) Hard-Mazz and Donglingcao are the host plant of imagos. Early sowing at an appropriate time and rotation are economic and effective to control this pest. To spread the mixture of poison insecticide soil on the land near maize plant is an important method to control larve in the field.
