草地螟是昆仑山区草场主要害虫之一。2011年4~8月,在新疆和田地区采取灯光诱杀和随机取样方法对草地螟分布进行调查。调查结果表明,海拔1984m草场草地螟成虫数量最多,依次为海拔2500m、3076m和3488m,不同海拔区草地螟成虫发生期基本相同。草地螟幼虫在海拔2950~3253m均有分布,其中海拔3055~3097m的虫口密度明显高于其他海拔区,海拔低于2800m和高于3400m的草场无草地螟幼虫分布。越冬代草地螟幼虫及蛹主要分布于海拔3028~3070m间的于田县阿羌乡塔孜克草场平均虫口密度284头/m~2,最高密度达296头/m~2。
Grasshopper is one of the main pests in the grassland of the Kunlun Mountains. From April to August 2011, the distribution of Meadow Stem Borer was investigated by light trapping and random sampling method in Hotan, Xinjiang. The results showed that the population of Meadow Borer was the highest at 1984 m grassland, followed by the elevation of 2500 m, 3076 m and 3488 m, and the occurrence of Meadow Borer adults at different altitudes was basically the same. Larval borer larvae are distributed at 2950 ~ 3253m above sea level, of which the population density of 3055 ~ 3097m above sea level is significantly higher than that of other altitude larvae at altitudes below 2800m and above 3400m. The larvae and pupae overwintering the grasshopper larvae and pupae were mainly distributed in the Taizik grass field of Aqiang Township, Yutian County, with an average population of 284 heads / m ~ 2 and a maximum density of 296 heads / m ~ 2 at an altitude of 3028 ~ 3070m.
