Microterys
Microterys is a large genus of parasitoid wasps in the family Encyrtidae (Chalcidoidea), with its center of distribution in the northern parts of the Northern Hemisphere. Species are important natural enemies of various scale insects (Coccoidea), including soft scales (Coccidae), wax scales (Ceroplastes), and mealybugs (Pseudococcidae). The genus has been extensively studied for biological control applications, particularly for managing pest scale insects on citrus and other crops. Several species have been introduced to new regions as biocontrol agents, including Microterys flavus in California.

Phenacoccus aceris
apple mealybug, maple mealybug
Phenacoccus aceris, commonly known as the apple mealybug or maple mealybug, is a widespread polyphagous mealybug species in the family Pseudococcidae. Native to Europe, it has become established across the Holarctic region including North America and Asia. The species is a significant agricultural and horticultural pest, feeding on phloem sap of numerous host plants including apple, maple, grapevine, ash, and prickly ash. Recent molecular and morphological studies have revealed that P. aceris represents a species complex containing multiple cryptic species, with taxonomic confusion arising from co-occurring putative species that cannot be reliably separated by host-plant associations alone. The species is also an important vector of grapevine viruses, transmitting six ampeloviruses and two vitiviruses.
