Simuliidae

 

(blackflies), a family of bloodsucking dipterous insects. The body length ranges from 1.5 to 7 mm. There are more than 1,200 species, distributed everywhere, from the tundra to the deserts. More than 300 species are found in the USSR. Blackflies usually winter in the egg phase; rarely do they winter in the larval one. They bear one to three or four generations a year. The larva and pupa develop in water, primarily in flowing water. Adults live outside the water. The males feed on plant juices, while the females are generally bloodsuckers. The insects are most active in the morning and evening. Their saliva is toxic.

Blackflies are carriers of the causative agents of helminthiases of man and animals (for example, onchocerciasis), as well as of leucocytozoon diseases of chickens, geese, ducks, pigeons, and turkeys. They are nonspecific carriers of the causative agents of a number of infectious diseases of man (for example, tularemia). Measures of individual protection include the use of curtains and nets treated with repellents. The larvae can be destroyed by using emulsions of insecticides.

Nas ultimas decadas, foi publicado um numero consideravel de estudos ecologicos acerca da familia Simuliidae nas regioes temperadas (CORKUM e CURRIE, 1987; CIBOROWSKI e ADLER, 1990; MCCREADIE e COLBO, 1991, 1992; MALMQVIST, 1994; MCCREADIE et al.
El aumento de las perturbaciones tiene efectos negativos sobre el control de insectos plagas en los humanos o el ganado (Culicidae, Chironomidae, Simuliidae, por ejemplo), ya que en habitats muy intervenidos la dominancia de estos grupos tiende a incrementar debido a la tolerancia que presentan frente a la depauperacion del habitat, disminuyendo asi la riqueza de insectos acuaticos que actuan como biorreguladores de estos insectos plagas, como en el caso de varias especies de las familias Libellulidae, Gomphidae y Coenagrionidae, por ejemplo (Garcia et al.

There are other bloodsucking insects, such as black flies or buffalo gnats (family Simuliidae, order Diptera), which are only 4-5 mm long, but their bite is much more painful than that of mosquitoes.
In contrast, streams that exhibit low shrimp densities have a larger population of filter-feeding Simuliidae and Trichoptera (Masteller and Buzby 1993, Buzby 1998; N.
This paracentricity is not surprising because inversions in a wide range of insects, including A nopheles (Green 1982), the Chironomidae (White 1978), and Simuliidae (Rothfels 1979), are paracentric rather than pericentric.

The number of instars is not fixed in Simuliidae, in contrast, for example, to Chironomidae and Culicidae, which are 2 families of aquatic Diptera in which there are 4 instars.
