Abstract

Eriophyoids are of great economic importance as pests of weeds, particularly in causing sometimes deformities such as bud galls, stunting, rusting, bronzing, leaf rolling, erineum, blisters, galls, coating, damaged seeds and mosaic virus disease. During the survey of eriophyoid mite fauna from Qualyubia, Cairo and Gharbia governorates in Egypt from 2014 to 2018. One new species and one new record of the genus Aceria from weeds are described and illustrated. Aceria lividus sp. nov., was collected from Amaranthus lividus L. (Amaranthaceae), vagrant on buds and flowers causing stunt and deformation. This species is the first record of eriophyoid mite from the family Amaranthaceae from Egypt. A supplementary description of the first record of Aceria malherbae Nuzzaci, 1985 infested Convolvulus arvensis L. (Convolvulaceae) in Egypt based on females, males and immature. This mite found on upper leaf surface alongside the midrib, causes leaf folding, deformation of flowers and plants and prevent plant reproduction. The two Aceria species indicate that is a promising candidate for the biological control of C. lividus and C. arvensis.
