Hydrellia pakistanae is a species of fly in the shore fly family, Ephydridae. [1] It is known as the Asian hydrilla leaf-mining fly. It is used as an agent of biological pest control against the noxious aquatic plant hydrilla (Hydrilla verticillata).
The adult fly is about 1.5 millimeters long, dark gray in color with a shiny metallic gold or silver face. The female lays eggs on the leaves of hydrilla above the surface of the water. In about three days the tiny eggs hatch, releasing the small white or yellow-green larvae. The larva of this fly is a leaf miner. It enters the flesh of the leaf and digs tunnels through it as it feeds. The larva eats nearly all of the inner tissue of the leaf before moving on to the next leaf. One larva finishes an average of twelve leaves during its two-week larval period. It then pupates for about a week and emerges as an adult. [2]
This insect has been shown to be effective in the destruction of hydrilla. The photosynthetic ability of the leaf is reduced with even a small amount of larva damage, and the feeding injury becomes susceptible to opportunistic fungal infection. [3] The buoyancy of the plant is reduced. As the infestation progresses, holes emerge in the hydrilla mat as plants begin to die and sink. As the hydrilla is eliminated, native plants can move in to repopulate the area. This fly is native to India and Pakistan, and it is currently established in hydrilla-prone areas in the southeastern United States where it was successfully introduced. It does best in warm areas and tends to be much less effective in areas that get cold. [2]
Flies are insects of the order Diptera, the name being derived from the Greek δι- di- "two", and πτερόν pteron "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described.
The Tachinidae are a large and variable family of true flies within the insect order Diptera, with more than 8,200 known species and many more to be discovered. Over 1300 species have been described in North America alone. Insects in this family commonly are called tachinid flies or simply tachinids. As far as is known, they all are protelean parasitoids, or occasionally parasites, of arthropods, usually other insects. The family is known from many habitats in all zoogeographical regions and is especially diverse in South America.
The apple maggot, also known as the railroad worm, is a species of fruit fly, and a pest of several types of fruits, especially apples. This species evolved about 150 years ago through a sympatric shift from the native host hawthorn to the domesticated apple species Malus domestica in the northeastern United States. This fly is believed to have been accidentally spread to the western United States from the endemic eastern United States region through contaminated apples at multiple points throughout the 20th century. The apple maggot uses Batesian mimicry as a method of defense, with coloration resembling that of the forelegs and pedipalps of a jumping spider.
Hydrilla (waterthyme) is a genus of aquatic plant, usually treated as containing just one species, Hydrilla verticillata, though some botanists divide it into several species. It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory, Queensland, and New South Wales.
The Phoridae are a family of small, hump-backed flies resembling fruit flies. Phorid flies can often be identified by their escape habit of running rapidly across a surface rather than taking to the wing. This behaviour is a source of one of their alternate names, scuttle fly. Another vernacular name, coffin fly, refers to Conicera tibialis. About 4,000 species are known in 230 genera. The most well-known species is cosmopolitan Megaselia scalaris. At 0.4 mm in length, the world's smallest fly is the phorid Euryplatea nanaknihali.
Ephydridae is a family of insects in the order Diptera.
Leptoconops torrens is a species of small biting flies in the no-see-um family Ceratopogonidae. They were first mentioned in writing by Charles Henry Tyler Townsend in 1893. The name Leptoconops carteri is a junior synonym of L. torrens. They are prevalent in the southwestern and southeastern areas of the United States. In early stages of life, L. torrens flies dwell in soil, then emerge to feed and breed as fully developed adults.
The Tephritidae are one of two fly families referred to as fruit flies, the other family being the Drosophilidae. The family Tephritidae does not include the biological model organisms of the genus Drosophila, which is often called the "common fruit fly". Nearly 5,000 described species of tephritid fruit fly are categorized in almost 500 genera of the Tephritidae. Description, recategorization, and genetic analyses are constantly changing the taxonomy of this family. To distinguish them from the Drosophilidae, the Tephritidae are sometimes called peacock flies, in reference to their elaborate and colorful markings. The name comes from the Greek τεφρος, tephros, meaning "ash grey". They are found in all the biogeographic realms.
A black fly or blackfly is any member of the family Simuliidae of the Culicomorpha infraorder. They are related to the Ceratopogonidae, Chironomidae, and Thaumaleidae. Over 2,200 species of black flies have been formally named, of which 15 are extinct. They are divided into two subfamilies: Parasimuliinae contains only one genus and four species; Simuliinae contains all the rest. Over 1,800 of the species belong to the genus Simulium.
Birch leafminers are sawflies, which are closely related to bees and wasps. They are among the most common insect pests affecting Birch trees in North America. Areas inside the leaves are consumed by the larvae, affecting the leaves' ability to produce food. Yearly browning of birch leaves are noticed in mid July and August, but the leafminers have been feeding inside the leaf tissue since early spring.
Rhagoletis mendax is a species of tephritid fruit fly known by the common name blueberry maggot. The blueberry maggot is closely related to the apple maggot, a larger fruit fly in the same genus. It is a major pest of plant species in the Ericaceae family, such as blueberry, cranberry, and huckleberry. The larva is 5 to 8 mm long, apodous, and white with chewing mouthparts. Female adults are 4.75mm in length, males are slightly smaller. Both adults are mostly black in color with white stripes, orange-red eyes, and a single pair of clear wings with black banding. The adult female fly lays a single egg per blueberry, and when the larva hatches it consumes the fruit, usually finishing the entire berry in under 3 weeks and rendering it unmarketable. The larva then falls to the soil and pupates. Adult flies emerge, mate, and females oviposit when blueberry plants are producing fruit. Each female fly can lay 25 to 100 eggs in their lifetime.
Chaetorellia acrolophi is a species of tephritid fruit fly known as the knapweed peacock fly. It is used as an agent of biological pest control against noxious knapweeds, especially spotted knapweed.
Larinus minutus is a species of true weevil known as the lesser knapweed flower weevil. It is used as an agent of biological pest control against noxious knapweeds, especially diffuse knapweed and spotted knapweed.
Bactrocera cucurbitae, the melon fly, is a fruit fly of the family Tephritidae. It is a serious agricultural pest, particularly in Hawaii.
Phytomyza ilicis, the holly leaf miner, is a leaf mining fly in the family Agromyzidae, whose larvae burrow into leaves of the holly tree leaving characteristic pale trails or leaf mines.
Trichopoda pennipes, common name feather-legged fly, is a fly in the family Tachinidae.
Galerucella calmariensis is a species of leaf beetle in the family Chrysomelidae. It is commonly known as the black-margined loosestrife beetle and is native to Europe and Asia where both adults and larvae feed on purple loosestrife. It has been introduced in North America as a biological control agent for purple loosestrife.
Anastrepha suspensa, known as the Caribbean fruit fly, the Greater Antillean fruit fly, guava fruit fly, or the Caribfly, is a species of tephritid fruit fly. As the names suggest, these flies feed on and develop in a variety of fruits, primarily in the Caribbean. They mainly infest mature to overripe fruits. While thought to have originated in Cuba, the Caribbean fruit fly can now also be found in Florida, Hispaniola, and Puerto Rico.
Liriomyza trifolii, known generally as the American serpentine leafminer or celery leafminer, is a species of leaf miner fly in the family Agromyzidae.
Atherigona soccata, the sorghum shoot fly, is a species of fly in the family Muscidae whose larvae feed on the central growing shoots of millet crops like sorghum and finger millet, as well as maize, where they can cause serious loss of yield across Africa and Asia.
