1977年,我区早稻后期局部地方粘虫暴发。我们读了《农业科技通讯》1977年第4期《国外科技参考消息》中《利用害虫体液防治害虫》一文,很受启发,我们试用粘虫体液防治粘虫,效果比较明显。6月26日,我们和大田公社新卜台大队植保员,在0.06亩水稻田上首次试验。当时粘虫密度为每亩45,600条,用天平秤取粘虫幼虫0.81克(折合每亩13.5克),捣碎 In 1977, some local armyworm outbreaks occurred in the early rice region of our district. We read “Agricultural Science and Technology Newsletter” No. 4 of 1977 “foreign science and technology reference information” in the “use of pests and body fluids pest control” article, very inspired, we try the armyworm liquid to control armyworms, the effect is more obvious. On June 26, we and the Daejeon Commune Shindai Battalion were first tested on 0.06 mu paddy fields. At that time, the density of armyworms was 45,600 per acre and the balance was 0.81g (equivalent to 13.5g per mu) with a balance scale and mashed
