| 摘 要： | 应用3种检验分布型的方法分别检验了宽须蚁蝗蝗蝻的分布型。结果表明：宽须蚁蝗蝗蝻在草地上的空间分型呈聚集分布，其聚集强度随种群的密度的升高而增加，应用Iwao模型中的参数估计了田间调查时的最适抽样数。

| Abstract: | Spatial distribution patterns of Myrmeleotettix palpalis populations were tested by three methods under alpine grassland conditions. The pattern of eggs and larvae conformed to aggregated distribution pattern and aggregation intensity increased with density of populations. Based on the parameters of Iwao model, an optimal sample size was estimated. |
