How to control wheat blossom midge? These methods you need to master
How to control wheat blossom midge? Please explain the methods. Wheat blossom midge can be controlled by referring to the following methods: 1. Occurrence patterns of wheat blossom midge. Wheat blossom midge has one generation per year. Overwintering larvae form cocoons in the soil at 20 cm to oversummer and overwinter. In the spring of the following year, when the temperature rises to 10 degrees (at this time wheat is at the jointing stage), the midge begins to break the cocoon and moves up into the 3-10 cm soil layer to prepare for pupation. When the temperature reaches 12 degrees (at this time it is the booting stage of wheat, mid-to-late April), the larvae successively pupate at about 3 cm on the soil surface. This is the best time to apply poisoned soil to control wheat blossom midge. Otherwise, after wheat heading, adult midges emerge in large numbers. Newly emerged adults can mate and lay eggs the same day. Each adult can lay dozens to over a hundred eggs. After 5-6 days, the eggs hatch into larvae, which bore into the wheat glumes and feed on the grain that is filling. In the late filling stage, mature larvae crawl out of the glumes after rain or when dew wets the wheat heads, fall to the soil, and oversummer and overwinter there. By wheat harvest, the damaged grains become "sparrow tongues" or "small black spots", shriveled and black, causing serious yield reduction.
