冬天,不见蝶舞,不闻蝉鸣,田野一片和平景象,而猖獗一时的害虫都到哪里去了呢?只要我们跟踪追击,就能找到各类害虫的越冬场所并进而消灭之。1、在地下越冬的害虫。如蝼蛄、蛴螬,是直接在地下越冬;棉铃虫骷虫、麦叶蜂等害虫则以老熟幼虫在地下建立蛹室化蛹越冬;而各种蝗虫则将卵产在地下间接越冬。对于这些害虫的越冬场所,我们可分别采取防治措施,如深秋或结冻前翻耕土地,来破坏它们的越冬场所,冻死这些害虫的幼虫、蛹和卵,既翻耕晒地养地,有利于土壤有益微生物的存活,也消灭了大量害虫,一举两得。
In winter, there is no splendor of the butterfly, no smell of cicadas, a scene of peace, and where are the pests of the rampant? As long as we follow the chase, we can find the overwintering places of all kinds of pests and then eliminate them. 1, overwintering pests in the ground. Such as 蝼 蛄, 蛴 螬, is the direct wintering in the ground; Helicoverpa armigera, wheat leaf bees and other pests to mature larvae in the ground to establish pupation chamber pupation overwintering; and a variety of locusts will lay eggs in the ground indirectly winter. For the overwintering sites of these pests, we can take preventive measures such as plowing the land before autumn or pre-freezing to destroy their overwintering places, freezing the larvae, pupae and eggs of these pests, Beneficial to the survival of soil beneficial microorganisms, but also eliminated a large number of pests, serve two purposes.
