Orseolia oryzivora, also called the African rice gall midge, is a species of small fly in the family Cecidomyiidae. It is a major insect pest of rice crops in Africa. [2] [1]

Monitoring

O. oryzivora and O. oryzae are morphologically, and even microscopically, indistinguishable, and so DNA differentiation methods have been developed. [3]

A midge is any small fly, including species in several families of non-mosquito Nematoceran Diptera. Midges are found on practically every land area outside permanently arid deserts and the frigid zones. Some midges, such as many Phlebotominae and Simuliidae, are vectors of various diseases. Many others play useful roles as prey items for insectivores, such as various frogs and swallows. Others are important as detritivores, and form part of various nutrient cycles. The habits of midges vary greatly from species to species, though within any particular family, midges commonly have similar ecological roles.

Cecidomyiidae Family of flies

Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only 2–3 mm (0.079–0.118 in) in length; many are less than 1 mm (0.039 in) long. They are characterised by hairy wings, unusual in the order Diptera, and have long antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa.

<i>Isachne</i> Genus of grasses

Isachne is a widespread genus of tropical and subtropical plants in the grass family, found in Asia, Africa, Australia, the Americas, and various oceanic islands. They may be known generally as bloodgrasses.

Orseolia oryzae, also called the Asian rice gall midge, is a species of small fly in the family Cecidomyiidae. It is a major insect pest of rice. The damage to the crop is done by the larvae which form galls commonly known as "silver shoots" or "onion shoots". The rice plant is stunted and the seed heads fail to develop.

Daphnephila taiwanensis is a species of gall midges first associated with leaf galls on Lauraceae species, particularly Machilus thunbergii in Taiwan. Based on analysis on sequences of the mitochondrial cytochrome c oxidase subunit I, it has been suggested that in this genus, the stem-galling habit is a more ancestral state as opposed to the leaf-galling habit. This genus appears to have originated tropically and dispersed to Japan through Taiwan.

Daphnephila sueyenae is a species of gall midges first associated with leaf galls on Lauraceae species, particularly Machilus thunbergii in Taiwan. Based on analysis on sequences of the mitochondrial cytochrome c oxidase subunit I, it has been suggested that in this genus, the stem-galling habit is a more ancestral state as opposed to the leaf-galling habit. This genus appears to have originated tropically and dispersed to Japan through Taiwan.

Daphnephila stenocalia is a species of gall midges first associated with leaf galls on Lauraceae species, particularly Machilus thunbergii in Taiwan. Based on analysis on sequences of the mitochondrial cytochrome c oxidase subunit I, it has been suggested that in this genus, the stem-galling habit is a more ancestral state as opposed to the leaf-galling habit. This genus appears to have originated tropically and dispersed to Japan through Taiwan.
