利用赤眼蜂防治松毛虫国内外有很多报导,但对其释放效果始终存在争议。有的认为神效无比,完全可以大面积推广;有的认为效果很差,盲目推广徒劳无益。到底怎样?我们认为,必须认真地调查,反复地研究,以实事求是的态度,说明赤眼蜂的真实价值。 为了尽快取得赤眼蜂防治松毛虫的统一意见,为生产实践提供可靠的科学依椐,本刊发表“赤眼蜂防治松毛虫效果的调查分析”、“赤眼蜂防治松毛虫效果的研究”两篇文章,望广大读者对此广泛的发表意见。
There are many reports at home and abroad on the prevention and treatment of pine caterpillars by Trichogramma, but there is always controversy about its release effect. Some think that the supernatural powers can completely popularize on a large scale. Some think that the effect is very poor and blind promotion does nothing. In the end? In our opinion, we must carefully investigate and study repeatedly to show the true value of Trichogramma under realistic conditions. In order to obtain the unified opinion on the prevention and control of pine trichomonas as soon as possible so as to provide a reliable scientific basis for production practice, this journal publishes the investigation and analysis of the effect of Trichogramma on preventing and controlling pine caterpillars, Two articles, hope the majority of readers express their opinions on this.
