摘 要
玉米螟是我市玉米生產(chǎn)上的主要害蟲，每年均有不同程度的發(fā)生，每年由于玉米螟 危害造成的損失達5%～10％左右，重發(fā)生年損失達１８％，嚴重影響我市玉米的產(chǎn)量和質(zhì)量。為了有效控制玉米螟的危害，我市從1995年開始推廣人工施放赤眼蜂防治玉米螟技術(shù)，效果非常顯著，得到了廣大農(nóng)民朋友的認可。為了進一步了解赤眼蜂對玉米螟的防效，為大面積推廣提供依據(jù)，我進行了多年的調(diào)查、試驗、分析，對赤眼蜂的放蜂方法、放蜂時間、防治效果進行了跟蹤調(diào)查，并與藥劑防治進行對比，得出了以下試驗結(jié)論。

Abstract
Corn borer is the main harmful insect which our city corn produces, each yearly average has the varying degree the occurrence, year to year loses 5% ~ about 10%, seriously has the year loss to reach 18%, seriously affects my city corn the output and the quality. In order to the active control corn borer harm, my city big area has promoted the trichogramma preventing and controlling corn borer technology, the effect was extremely remarkable, obtained the general farmers friend's approval. In order to understand trichogramma to corn borer guards against the effect, provides the basis for the big area promotion, has carried on many years experiment, put the bee method to the trichogramma, puts the bee time, the preventing and controlling effect has carried on the track investigation, and carried on the contrast with the chemical control, has drawn below the conclusion.
Key words: corn；corn borer protection；oophagous trichogrammae；honey campain；protection
