无视异绒螨(Allothrombium ignotum Willman)是棉蚜的一种寄生性天敌。研究结果表明:该种天敌发生时间早,数量大,与棉蚜的种群波动呈明显的同步关系;加之它与棉蚜的时间一空间生态位重叠度高,二者的空间格局一致,所以对抑制早期棉蚜基数的增长具有重要的作用。
Ignoring Allothrombium ignotum Willman is a parasitic natural enemy of cotton aphid. The results showed that the natural enemies occurred earlier and larger in quantity, which showed a significant synchronization with the population dynamics of cotton aphid. In addition, the natural enemies had a high temporal-spatial niche overlap with the cotton aphid, and their spatial patterns were consistent Inhibition of early cotton aphid base growth has an important role.
