摘要: During observations in soybean fields, 136Neoscona arabesca (Walckenaer) and 46Tetragnatha laboriosaHentz were collected with prey. Significantly different prey compositions recorded, withN. utilizing a large number ofColeoptera whileT. laboriosa captured primarilyHemiptera-Homoptera. Neoscona was observed to feed primarily the evening following web construction, fed predominantly morning. Although both of these species relatively numbers homopterans, most their which are not considered be pests soybean.
