Diaspididae
Armored Scale Insects, Armored Scales, Hard Scales
Diaspididae is the largest family of scale insects, comprising over 2,650 described species in approximately 400 genera. Members are commonly known as armored scale insects due to their distinctive protective covering, which incorporates exuviae from the first two nymphal instars, sometimes with fecal matter and host plant fragments. The female remains permanently beneath this armor, feeding on host plant tissues through piercing-sucking mouthparts. The family includes numerous economically significant pests such as the California red scale (Aonidiella aurantii), San Jose scale (Diaspidiotus perniciosus), and gloomy scale (Melanaspis tenebricosa), which damage crops, ornamentals, and forest trees worldwide.
Lilioceris
lily leaf beetles, air potato leaf beetles
Lilioceris is a genus of leaf beetles (Chrysomelidae) in the subfamily Criocerinae, first described by Edmund Reitter in 1912. The genus contains over 100 species, with approximately 80 species occurring in Asia. Several species are notable agricultural and horticultural pests, particularly of plants in the lily family (Liliaceae). Lilioceris lilii (lily leaf beetle) is a serious pest of native and cultivated lilies in Europe and North America, while L. cheni has been successfully deployed as a classical biological control agent against the invasive air potato vine (Dioscorea bulbifera) in Florida. Species range from 4–10 mm in length with elongated, narrow bodies and distinct shoulders between the elytra and pronotum.
Panaphidini
Panaphidini is a tribe of aphids within the subfamily Calaphidinae, established by Oestlund in 1923. The tribe comprises approximately 50 genera divided into two subtribes: Myzocallidina and Panaphidina. Many genera are associated with woody host plants, particularly in the families Fagaceae, Betulaceae, and Salicaceae. The tribe includes economically significant pests such as species of Tinocallis and Monellia.
