Paracrias is a genus of hymenopteran insects of the family Eulophidae. Larvae are gregarious parasitoids of Curculionoidea, with P. huberi being a parasitoid of H. analis . [1]
Chalcid wasps are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, meaning the vast majority have yet to be discovered and described. The name "chalcid" is often confused with the name "chalcidid", though the latter refers strictly to one constituent family, the Chalcididae, rather than the superfamily as a whole; accordingly, most recent publications (e.g.,) use the name "chalcidoid" when referring to members of the superfamily.
Apocrita is a suborder of insects in the order Hymenoptera. It includes wasps, bees, and ants, and consists of many families. It contains the most advanced hymenopterans and is distinguished from Symphyta by the narrow "waist" (petiole) formed between the first two segments of the actual abdomen; the first abdominal segment is fused to the thorax, and is called the propodeum. Therefore, it is general practice, when discussing the body of an apocritan in a technical sense, to refer to the mesosoma and metasoma rather than the "thorax" and "abdomen", respectively. The evolution of a constricted waist was an important adaption for the parasitoid lifestyle of the ancestral apocritan, allowing more maneuverability of the female's ovipositor. The ovipositor either extends freely or is retracted, and may be developed into a stinger for both defense and paralyzing prey. Larvae are legless and blind, and either feed inside a host or in a nest cell provisioned by their mothers.
The Eulophidae is a large family of hymenopteran insects, with over 4,300 described species in some 300 genera. The family includes the genus Elasmus, which used to be treated as a separate family, "Elasmidae", and is now treated as a subfamily of Eulophidae. These minute insects are challenging to study, as they deteriorate rapidly after death unless extreme care is taken, making identification of most museum specimens difficult. The larvae of very few species feed on plants, but the majority are primary parasitoids on a huge range of arthropods at all stages of development. They are exceptional in that they are one of two hymenopteran families with some species that are known to parasitize thrips. Eulophids are found throughout the world in virtually all habitats.
Cecidosidae is a family of primitive monotrysian moths in the order Lepidoptera which have a piercing ovipositor used for laying eggs in plant tissue in which they induce galls, or they mine in bark. Nine species occur in southern Africa, five species in South America and Xanadoses nielseni was recently described from New Zealand. Some minute parasitoid wasps are known.
Baeoentedon is a genus of hymenopteran insects of the family Eulophidae, they are parasitoids of whitefly from the family Aleyrodidae which are found on trees of the genus Ficus. They have been recorded from Australia, China, India, Indonesia and Florida. A fifth species, Baeoentodon farazi, was described from Karnataka, India, in 2017.
Emersonella is a genus of hymenopteran insects of the family Eulophidae. Several species are known to be phoretic parasitoids of female tortoise beetles, laying their eggs in the eggs of the beetle host.
Euplectrus is a genus of hymenopteran insects of the family Eulophidae.
Goetheana is a genus of hymenopteran insects of the family Eulophidae. As a parasitoid of thrips, this wasp is used in biological pest control.
Horismenus is a genus of hymenopteran insects of the family Eulophidae occurring primarily in the Americas. As of 2015 over 400 species in the genus have been described. Horismenus species are often described as parasitizing other insects.
Kokandia is a monotypic genus of hymenopteran insects of the family Eulophidae. The only known species Kokandia salsolicola is a parasitoid of gall midges belonging to the family Cecidomyiidae which use plants of the goosefoot genus Salsola as hosts.
Leptocybe invasa, the blue gum chalcid wasp or eucalyptus gall wasp, is a chalcid wasp which is the only species in the monotypic genus Leptocybe in the subfamily Tetrastichinae, of the family Eulophidae. It is a gall wasp which causes the formation of galls on a number of species of Eucalyptus, it was described in 2004 after galls were found in river red gums in the Mediterranean and Middle East and has since been found to be a widespread species where its host trees are planted. It is indigenous to Australia.
Melittobia is a genus of hymenopteran insects of the family Eulophidae.
Pnigalio is a genus of hymenopteran insects of the family Eulophidae. Nearly 100 species have been described of which about half may be valid. All species are parasites of other insects. Their biology varies widely among those species that have been studied. Some are ectoparasites, others parasitoid, and still others are hyperparasitoids and their hosts include beetles, flies, hymenopteran and lepidopterans.
Quadrastichus is a genus of hymenopteran insects of the family Eulophidae.
Tetrastichus planipennisi is a parasitic non-stinging wasp of the family Eulophidae which is native to North Asia. It is a parasitoid of the emerald ash borer, an invasive species which has destroyed tens of millions of ash trees in its introduced range in North America. As part of the campaign against the emerald ash borer (EAB), American scientists in conjunction with the Chinese Academy of Forestry searched since 2003 for its natural enemies in the wild leading to the discovery of several parasitoid wasps, including Tetrastichus planipennisi which is a gregarious endoparasitoid of EAB larvae on Manchurian Ash and has been recorded to attack and kill up to 50 percent of EAB larvae.
Quadrastichus erythrinae Kim, 2004, is a small parasitoid wasp belonging to the family Eulophidae, but also a secondary phytophage by way of inducing galls on the leaves, stems, petioles and young shoots of various Erythrina species.
Tetrastichinae is a subfamily of the chalcid wasp family Eulophidae. It is one of the largest subfamilies of the Eulophidae containing over 100 genera and nearly 3,000 species. The species of the family Tetrastichinae are found in almost any type of terrestrial habitat and have a worldwide distribution, except Antarctica. They show a varied biology and hosts for Tetrastichinae wasps have been identified from over 100 different insect families, across 10 different orders and they have also been recorded as being parasitoids on nematodes, mites and spiders' eggs. Some species are even phytophagous, while others are inquilines and yet others are gall formers.
Selitrichodes is a genus of hymenopteran insects of the family Eulophidae, most of which are parasitoids associated with gall producing insects on Eucalyptus.
Minotetrastichus frontalis is a species of chalcid wasp in the family Eulophidae. It is a parasitoid of Phyllonorycter moths, with larvae capable of feeding on both larval and pupal stages of the moth. M. frontalis has four larval stages and three molts, with development lasting eleven days.
Pnigalio mediterraneus is a species of insect in the family Eulophidae. It is a parasitoid of the olive fruit fly and the horse-chestnut leaf miner.
