蠅3齡幼蟲存在著種內干擾,其尋找效應隨著自身密度的增加而降低,其分攤競爭強度隨著自身密度的增加而增加。
The best searching densities of the first, second and third instar larva of e. balteatus are 6. 73, 10. 09 and 44. 03 aphids respectively. 3. the predation ratio of e. balteatus is the lowest at 14 ? and the predation ratio at 18 c, 22 c, 26 c and 30 c are not different
