我大队位于滹沱河西南的南山脚下,是一个土壤类型较复杂的地方,适于各种蛴螬繁殖为害。根据成虫诱杀和大田调查,有华北大黑鳃金龟、黑绒金龟、阔胸犀金龟、铜绿丽金龟、四纹丽金龟、黄褐丽金龟等6种。其中分布最广、为害最重的是华北大黑鳃金龟,现将我们的初步观察和防治对策简述如下。 My brigade is located at the foot of Nanshan in the southwest of Hutuo River and is a place where soil types are more complex. It is suitable for reproduction of all kinds of grubs. According to adult trapping and field surveys, there are 6 species of giant black gills, black turtles, broad-bodied rhinoceros beetles, bronze green beetles, four-streaked beetle and yellow brown beetles. One of the most widely distributed, the most damaging is the North China gill beetle, now our preliminary observation and prevention and control measures outlined below.
