已查明四川高梁穗部害虫有54种。其中,粟穗螟(Mampavabipunctella Ragonot)、桃柱野螟(Dichocrocis punctiferalis Guence)为主要虫种。高粱花翅小卷蛾(Lobesia aeolopa Meyriek)、柑桔长卷蛾(HomonaCoffearia Meyrick)为次要虫种。棉铃实夜蛾(Heliothis armigeva Hubner)为局部偶发成灾种类。其余49种属于少量或零星发生种类。害虫种类以盆南高温区域最多,随纬度北移和海拔上升而减少。根据穗虫群落构成和发生动态,可将四川省高粱穗部害虫群落分为粟穗螟为主区和桃蛀野螟为主区。
Sichuan has identified 54 species of spike ears of sorghum. Among these, Mampava bipunctella Ragonot and Dichocrocis punctiferalis Guence were the main species. Lobesia aeolopa Meyriek and HomonaCoffearia Meyrick are minor insects. Heliothis armigeva Hubner is a local accidental species. The remaining 49 species belong to small or sporadic occurrences. Pest species to the highest temperature in the basin south, with the latitude northward and elevation increases. According to the composition and occurrence of the earworm community, the earworm communities of sorghum in Sichuan Province can be divided into the main area of the corn borer and the moth borer.
