拟环纹狼蛛是稻田蜘蛛的主要优势种之一,其体形较大,捕食力强,与水稻主要稻虫的稻飞虱、稻叶蝉生境一致,成正相关。在日本,桐谷认为被捕食的飞虱、叶蝉,90％是它的功劳。我们认为,将90％被捕食的飞虱、叶蝉功劳归于它,可能估计过高,但它的确是稻田中很有利用前途的蛛种,值得进一步研究。因此,我们在1977年—1980年的田间季节消长、
The spider was one of the dominant species of spider in paddy fields. Its shape and predation were positively correlated with those of rice planthoppers and rice leafhoppers. In Japan, Tong Valley believes that preyed on planthoppers, leafhoppers, 90% is its credit. We think it may be overestimated to credit 90% of the preyed on planthopper and leafhopper for its contribution, but it is indeed a promising species of spider plantation in paddy field that deserves further study. As a result, we have seen a decline in the field season of 1977-1980,
