摘要
1987年研究结果表明,江南稻田微蛛有10种,其中食虫沟瘤蛛为各地稻田的优势种,在湖南占微蛛总量的90%左右,草间小黑蛛、驼背额角蛛和齿螯额角蛛在某些地区成为优势种。湖南各地微蛛平均发生量在3月、6月、9月和12月分别为7638头/亩、11585头/亩、7983头/亩和4686头/亩。
It is known from the study made in 1987,there are 10 species of the micry-phantid spiders in paddy field in the south of the Yangtze River.Ummeliata in-secticeps is dominant in all paddy fields.Its population quantities are about 90%among the micryphantid spiders in Hunan.Erigone graminicolum,Gnathonariumgibberum and G.dentatum can become dominant in some paddy-growing area.InMarch,June,September and December,the mean population quantities of themicryphantid are 7638,11585,7983 and 4686 per mu respectively in all area ofHunan.
