采用聚集度指标法测定竹缺爪螨(Aponychus corpuzae)空间格局并分析其时序动态。结果表明:竹缺爪螨卵及卵壳在林间呈聚集分布,主要分布在3年生以上竹(受害株率为97.414 3%),2年生以下竹分布株率仅占0.857 1%,这说明该螨主要危害3年生以上竹,且以聚集为危害为主。卵和幼螨群体在年周期中均呈聚集分布,其聚集程度对若和成螨具跟随效应。若虫和成螨存在明显的聚集—扩散周期,10 a中大多数时期呈聚集分布,少数时期呈均匀分布或Poisson分布。这与该螨生物学特性及气候、营养条件密切相关。图1表2参8

By means of several sorts of indexes of aggregation,the spatial distribution pattern of Aponychus corpuzae was measured.The results indicated:the egg's and their crusts' spatial pattern were of an aggregation distribution in the bamboo forest,and they distributed mainly on the leaves of over 3-age bamboos and only 0.857 1% on the leaves of under 2-age bamboos;it showed that the mites harmed mainly over 3-age bamboos;the eggs and larvae mere of an aggregation distribution in a year but had different degree of aggregation which followed the nymphs and adults;The nymphs and adults had clear aggregation-spread circulation in year.which were of an aggregation distribution in long term and of an ayerage or Poisson distribution in short term;it was relationship with the biology of the mites,climate and food;in the last,the applications of study results on the control of the mites were discussed.
