蛴螬是金龟子的幼虫,是茂汶县农作物的主要地下害虫之一,常年发生严重。危害面积达2.45万亩,占农耕地的19.6％。历年来虽用六六六粉防治,但防效甚微,致使每年损失产量约232万斤。据31个点大田调查,海拔2,000公尺以上的农耕地主要是大粟鳃金色(虫甲),约占种群的83.5％。为了有效地防治蛴螬,减轻为害,我站于1982年用辛疏磷进行防治试验、示范,效果显著。1983年推广防治面积13,300亩,占发生面积的54.28％,相对平均防效达82.52％,挽回产量损失113.05万斤。
Scabies are beetles’ larvae, one of the major underground pests of the crop in Maowen County, perennial. Hazardous area of 24,500 mu, accounting for 19.6% of farmland. Over the years though six six six powder prevention and control, but very little effect, resulting in annual loss of about 232 kg of output. According to a survey of 31 spots in Daejeon, the cultivated land above 2,000 meters above sea level is dominated by golden gourd, which accounts for 83.5% of the population.

In 1983, 13,300 mu of prevention and control area was popularized, accounting for 54.28% of the occurring area. The relative average control efficiency reached 82.52%, and the loss of output was 1.135 million kilograms.
