摘要: 本研究在吴县陆墓公社32段有钉螺的河、沟中进行。研究结果发现河、沟钉螺的检出情况与螺口多少有关,第1次查螺检出的活螺密度与实际活螺密度之间呈线性正相关;在4、5月份作一次全面细查后,一般第1次的检出情况能反映出当时被查河、沟的螺口多少;但螺口密度很低的河、沟(实际活螺密度在每平方市尺0.7只以下)在第1次查螺时可能检不出。又发现螺卵密度与实际活螺密度之间也呈线性正相关。

Abstract: Studies were undertaken in 32 Oncomelania Snail-infected canal sections in Lumu Commune of Wuxian County in 1980. The results showed that the snail density in each canal section determined in the first survey was parallel to the total population of that section. There was a linear positive correlation between the snail density detected in the first survey and the density of the total snail population. However in low snail popular tion (below 0.7/square Chinese foot) area, snails may not be detected in the first survey. Results also showed that a linear positive correlation existed between the density of the snail eggs and the density of the total snail population.
