the majority of eriophyid mites are phytophagous and some of them are important pests of plants. however, due to host specificity and other bioecological characteristics seen in members of this family, they are considered as important biocontrol agents of weeds. in order to identify the eriophyid mites associated with important weeds in agroecosystems in razavi khorasan province, during 2010 an...

Structures on the surfaces of leaves, such as dense layers of non-glandular trichomes, strongly affect phylloplane mite activities. On the other hand the feeding of eriophyoid mites on leaf surfaces can cause hyperplasia of leaf trichomes (erinea formation). In many cases the hyperplasia is accompanied by the accumulation of pigments within trichome cells, causing an impressive red-brown colour...

The eriophyid mite transmitted Wheat streak mosaic virus (WSMV; genus Tritimovirus, family Potyviridae) shares a common genome organization with aphid transmitted species of the genus Potyvirus. Although both tritimoviruses and potyviruses encode helper component-proteinase (HC-Pro) homologues (required for nonpersistent aphid transmission of potyviruses), sequence conservation is low (amino ac...
