Eriococcidae
Eriococcidae is a family of scale insects in the order Hemiptera. They are commonly known as felt scales or eriococcids. Each species is usually specific to a different plant host, or closely related group of hosts. Recent research using ribosomal DNA has shown that the family Eriococcidae is not a single monophyletic group but is an aggregation of several different groups. Some species that appear morphologically similar seem to be only distantly related while dissimilar species are sometimes more closely related.Cook, L.G. & Gullan, P.J. 2004: The gall-inducing habit has evolved multiple times among the eriococcid scale insects (Sternorrhyncha: Coccoidea: Eriococcidae). ''Biological Journal of the Linnean Society'', 83: 441-452. DOI: 10.1111/j 1095-8312.2004.00396.x The type genus '' Eriococcus'' has been shown to be polyphyletic. Morphology Felt scales are a diverse group of scale insects. They produce a white, yellowish or gray membranous capsule or ovisac that encloses the p ...

Apiomorpha
''Apiomorpha'' is a genus of scale insect that induces galls on species of ''Eucalyptus''. Galls are initiated by first-instar nymphs (crawlers) on new plant growth and, when mature, the galls exhibit marked sexual dimorphism. Those induced by females are among the largest and most spectacular of arthropod-induced galls whereas those of males are small and most are tubular.Gullan, P.J. 1984. A revision of the gall-forming coccoid genus ''Apiomorpha'' Rübsaamen (Homoptera: Eriococcidae: Apiomorphinae). Aust. J. Zool. Suppl. Ser. 97:1-203. doi:10.1071/AJZS097 ''Apiomorpha'' is known only from Australia and New Guinea although its host, ''Eucalyptus'', has a wider distribution into Indonesia as well. ''Apiomorpha'' is currently classified in the Eriococcidae, but this family is not monophyletic. Morphology Like other scale insects, ''Apiomorpha'' is highly sexually dimorphic. Adult females are wingless, have very small (or no) eyes, and their legs are short and stubby. A female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scale Insect
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 descr ...

Callococcus
''Callococcus'' is a genus of Australian scale insect that feeds on species of '' Leptospermum'', ''Hypocalymma'', ''Kunzea'' and some other members of the tribes Chamelaucieae and LeptospermeaeGullan P.J., Miller D.R. & Cook L.G. (2005). Gall-inducing scale insects (Hemiptera: Sternorrhyncha: Coccoidea). In: Biology, Ecology, and Evolution of Gall-Inducing Arthropods (eds. Raman A, Schaefer CW & Withers TM). Science Publishers New Hampshire, pp. 159-229. in the myrtle family Myrtaceae. ''Callococcus leptospermi'' induces stem-swelling galls on some species of ''Leptospermum'', and it is considered to be a potential biological control agent of ''Leptospermum laevigatum'' in South Africa. The other described species of ''Callococcus'' do not induce galls. Morphology As for most scale insects, the taxonomy of ''Callococcus'' is based on the morphology of the adult female. Like adult females of other scale insects, those of ''Callococcus'' have no wings. They also have no leg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
