- 摘要:
- 筛豆龟蝽已成为我国华东地区大豆田的重要害虫。为制定科学的害虫种群数量抽样方案,准确监测其发生动态,采用全查法和五点取样法,对南京市郊大豆田(结荚初期)内筛豆龟蝽的卵、若虫与成虫等虫态的分布进行了调查,并采用频次分布拟合以及若干聚集度指数测定的方法,对调查结果进行了分析。经频次分布检验,卵、若虫和成虫田间分布型均符合负二项分布,属于聚集分布型;多种聚集度指数检验结果也显示出,筛豆龟蝽个体属聚集分布,与频次分布检验结果一致。
- Abstract:
- Meagcopta cribraria(Hemiptera:Pentatomidae) has become a destructive pest on the soybean crop in eastern China.In order to accurately estimate the pest population based on a sound sampling design,the all-count method and the five-point sampling method were used to survey eggs,nymphs and adults during early pod-setting stage of soybean.Frequency distributions were tested for the fit of statistical distribution models,and several indices of dispersion were used to measure the spatial pattern.The results showed that spatial distributions of the egg,nymph and adult belonged to the negative binomial,which indicated the clumping distribution of individuals at different life stages of Meagcopta cribraria in the soybean field.
