我省农作物害虫种类多,分布广,为害大,历年一般作物遭受虫害损失多在百分之十左右,严重的达百分之二、三十,是农业生产上的一大敌害。去秋以来,天气晴燥,秋冬作物较多,冬耕面积较小,因之虽有严寒冰冻,但二花螟抵抗力强,害虫死亡不多,根据今春洞口、湘乡、新宁、城步、隆同等县在田间检查的结果,七九二个禾蔸中,有螟虫六五七条,仅死七一条,越冬死亡率祇百分之十点九,比五二年越冬死亡率低百分之十九点二,比五三年冬低百分之一点八。又常宁一区嵩塘农业社一亩七分秧田,五月六日一次诱捕螟蛾二九○多只。上述情况说明害虫密度大,越冬死亡少,对今年农业增产仍是一个非常严重的威胁,必须加以防治。为此,特作如下指示: There are many kinds of crop pests in our province, which are widely distributed and harmful to crops. In general, crop losses suffered by pests during the previous years are mostly about 10% or so serious, and 2% or 30% of them are seriously harmed by agricultural production. Since the fall of autumn, the weather is clear and dry, more crops in autumn and winter, winter plowing area is small, although the cold frost, but two strong resistance to the firefly, pest death is not much, according to this spring hole, Xiang, Xinning, City As a result of the field inspection carried out in the same county by step, Longdong, there were 657 deaths of stem borers in seventy-two grasslands, only 71 deaths, and the overwintering mortality rate was only 10.9% over the five-year mortality rate Low 19.2%, down 1.8% from the winter in 533. And often Ning District Songtang agricultural cooperatives acre seven seedlings, on May 6 a trap moth moth more than 190 only. The above situation shows that the pest density is high and there are few winter deaths. It is still a very serious threat to this year’s agricultural increase and must be prevented and dealt with. To this end, special make the following instructions:
