Tumidiclava is a wasp genus in the family
Parasites: on eggs:
or Sceleonidae, on larva: "Carcelia evoluans".
Prestwichia is a wasp genus in the family
. I contains seven species.
Megaphragma is a wasp genus in the family
. It contains two of the four smallest known insects, "Megaphragma caribea" (170 micrometers) and "Megaphragma mymaripenne" (200 micrometers).
Trichogramma are minute polyphagous wasps that are endoparasitoids of insect eggs. "Trichogramma" is one of around 80 genera from the family
, with over 200 species worldwide.
Because of their small sizes, fairyflies may sometimes be mistaken for members of the families Aphelinidae and
, but members of these other families can readily be distinguished by having much shorter antennae.
Parasitoids hosted by the Cecidomyiidae, thereby limiting the gall midge population include the Braconidae (Opiinae, Euphorinae) and chalcidoid wasps in the families Eurytomidae, Eulophidae, Torymidae, Pteromalidae, Eupelmidae,
, and Aphelinidae. All contain species which are actual or potential biolological agents.
Adryas bochica is a species of bee in the genus "Adryas" of the family
. It was first described by Pinto and Owen in 2004. Holotypes of the species are stored in the Riverside Entomology Department collection of the University of California.
Wasps are the most commonly reported parasitoids of Karner blue butterflies. A tachinid fly, "Aplomya theclarum", has also been listed as a Karner blue butterfly parasite. Two wasps, one from the
family and another tentatively identified as a member of the Eulophidae family, are suspected to parasitize Karner blue butterfly eggs.
have unique nervous systems resulting from the necessity to conserve space. They have one of the smallest nervous systems, with one particularly diminutive species, "Megaphragma mymaripenne", containing as few as 7,400 neurons. They are also the first (and only) known animals which have functioning neurons without nuclei.
Trichogramma brassicae is a species of parasitoid wasp from the
family. It mainly parasitizes Lepidopteran hosts in agricultural fields. They are entomaphagous parasitoids that deposit their own eggs inside the host's eggs, consuming the host egg material and emerging upon full development. They are a common biological control species that have been used commercially since the late 1970s.
are a family of tiny wasps in the Chalcidoidea that include some of the smallest of all insects, with most species having adults less than 1 mm in length. The over 840 species are in about 80 genera; their distribution is worldwide. Trichogrammatids parasitize the eggs of many different orders of insects. As such, they are among the more important biological control agents known, attacking many pest insects (esp. Lepidoptera).
The UCR collection of Chalcidoidea (Hymenoptera) is one of the world's largest of this group, and the slide collection of Chalcidoidea has no comparison in the world (more than 100,000 slides, primarily
, Aphelinidae, Mymaridae, Eulophidae, and Encyrtidae). Additional specialty taxa represented as slides or pinned specimens are Apoidea, Asiloidea (esp. Bombyliidae, Therevidae, Asilidae), Meloidae, Thysanoptera, Staphylinidae, Melyridae, Coccinellidae, Sciomyzidae, Tephritidae, Miridae, Aphididae, Coccoidea, and various selected genera (e.g., the scarab genera "Pleocoma" and "Chrysina"). The holdings include over 1,100 primary types and many thousands of paratypes of the preceding taxa (the majority attributable to P.H. Timberlake).
Due to their small sizes and high rates of reproduction, thrips are difficult to control using classical biological control. Suitable predators must be small and slender enough to penetrate the crevices where thrips hide while feeding, and they must also prey extensively on eggs and larvae to be effective. Only two families of parasitoid Hymenoptera parasitize eggs and larvae, the Eulophidae and the
. Other biocontrol agents of adults and larvae include anthocorid bugs of genus "Orius", and phytoseiid mites. Biological insecticides such as the fungi "Beauveria bassiana" and "Verticillium lecanii" can kill thrips at all life-cycle stages. Insecticidal soap spray is effective against thrips. It is commercially available or can be made of certain types of household soap. Scientists in Japan report that significant reductions in larva and adult melon thrips occur when plants are illuminated with red light.
Some species of parasitic wasp, especially in the
, are exploited commercially to provide biological control of insect pests. For example, in Brazil, farmers control sugarcane borers with the parasitic wasp "Trichogramma galloi". One of the first species to be used was "Encarsia formosa", a parasitoid of a range of species of whitefly. It entered commercial use in the 1920s in Europe, was overtaken by chemical pesticides in the 1940s, and again received interest from the 1970s. "Encarsia" is used especially in greenhouses to control whitefly pests of tomato and cucumber, and to a lesser extent of aubergine (eggplant), flowers such as marigold, and strawberry. Several species of parasitic wasp are natural predators of aphids and can help to control them. For instance, "Aphidius matricariae" is used to control the peach-potato aphid.
Eggs are laid by the female with her saw-like ovipositor in slits cut into the cambium or live tissue of stems, though some species lay eggs on top of leaves or stems. The eggs may be parasitised by wasps, such as the tiny fairyflies (Mymaridae) and
. The females of some membracid species sit over their eggs to protect them from predators and parasites, and may buzz their wings at intruders. The females of some gregarious species work together to protect each other's eggs. In at least one species, "Publilia modesta", mothers serve to attract ants when nymphs are too small to produce much honeydew. Some other species make feeding slits for the nymphs.
