为了利用有益生物防治病虫害,从1973年起我省许多单位在省农业局的领导下组织起来,陸续开展了应用赤眼蜂防治粮、棉、果、林害虫的研究工作。几年来本着一边积极试验研究,一边大力进行示范、推广。目前我省应用赤眼蜂防治农业害虫的面积已超过500万亩,普遍收到了良好的效果。应用赤眼蜂防治农业害虫工作,除了必须对害虫的发生规律作更深入的了解外,还需对赤眼蜂本身进行相当的调查研究,并弄清两者之间的关系。这样才能达
In order to take advantage of beneficial organisms to control pests and diseases, many units in our province have been organized under the leadership of the Provincial Bureau of Agriculture since 1973, and successively carried out researches on the prevention and control of grain, cotton, fruit and forest pests by Trichogramma. Over the past few years based on the positive experimental research, while vigorously carry out demonstration and promotion. At present, the area of application of Trichogramma in prevention and control of agricultural pests in our province has exceeded 5 million mu and generally received good results. Trichogramma application of agricultural pest control work, in addition to the law of pests have to be more in-depth understanding of the need Trichogramma itself, a considerable investigation and study, and find out the relationship between the two. This can be achieved
