Acalitus
Acalitus is a genus of microscopic eriophyoid mites in the family Eriophyidae. Species within this genus are cosmopolitan plant parasites that induce gall formation on various host plants. Several species are significant agricultural pests, including Acalitus essigi and Acalitus vaccinii, which affect berry crops, and Acalitus phloeocoptes, which damages stone fruit trees. The genus exhibits narrow host specificity, with individual species typically restricted to particular plant genera or families.
Hyalopterus pruni
Mealy Plum Aphid
Hyalopterus pruni, the mealy plum aphid, is a sap-feeding aphid in the family Aphididae with a cosmopolitan distribution. It exhibits a complex life cycle involving multiple generations of wingless adults followed by the production of winged migrants that disperse to secondary hosts. The species is notable for its waxy covering and seasonal host alternation between Prunus species and grasses or reeds.
