These insects are known to every lover of violets. Some small mosquitos flying above ghiveciurilor with flowers. Sometimes they disappear, sometimes flies with hundreds of plants around the room.
Mosquitoes belonging to the family Sciaridae fungus are spread all over the world, but at the same time remain the least studied group of the order of insects with two Wings wings.
Sciaridele are some living fossils, being one of the oldest groups of dipteran insects. Due to its small size and Larval phase isolated, sciaridele long time no have attracted the attention of anyone. Now, family in question has over 1700 species studied.
African violet enthusiasts meet representatives of three species: Sciara, Bradysia and Lycoriella. Without a microscope, It's pointless to distinguish between them.
In flower pots with plants, sciaridele end up with either the soil substrate, be outside, by depositing eggs in moist soil in pots.
Ridding the mosquitos fungus once and for all is impossible. If there are conditions of feeding and breeding, they will come back over and over again at Your flowers.
Excess soil moisture, and high content of organic matter in decomposition represents the conditions of reproduction of sciaridelor.
Sciarid is a midge size of 0.5-2 mm with a narrow body and round head. The body color may differ depending on species, but it is usually gray or black. The "mouth" of the adult musculitei are underdeveloped. The wings of many sciarid species are well developed, but meet and species without wings.
Adult insects don't feed and doesn't harm the plants.
The female lays eggs in wet soil and slightly acid. After about a week, larvae hatch from eggs the size 2-10 mm. Sciaridelor larvae have legs, they are also known as, small translucent and have big head black. They can leave you gumming a trail above the ground, barely visible. If the larvae of sciaridelor would be taken from the wet soil, they would die in a few minutes. So, they do not support a dry soil.
African mature Violetelor, mosquitos fungi cannot in any way damage. Instead, the larvae are fearsome enemy. They feed on organic matter decomposition in soil, at the same time attacking the roots of the plants. If plants are grown under normal conditions and cultivation techniques are applied correctly, injuries of the larvae in the root system are minor and are compensated by the growth of new roots. In the case of mass reproduction of sciaridelor, the larvae feed on living tissues with plant. Some species of musculite for example, white fly cucumber (Bradysia brunnipes Mg.) and greenhouse white fly (Perniciosa Plastosciosa Lcc) love the roots and plant parts that touch the ground, daunand transplants.
The species of the flower pots of sciarid, no serious harms plants House.
Fight sciaridele, podura and lice of root proves to be a work of Sisyphus. These insects will appear always in our flower pots.
When the mosquitos are mushrooms with hundreds, and their larvae are easy as the teeming through the ground, they become a real issue.
The fighting sciaridelor, especially helpful is the shredded bark of coconut nuts, If it is added in soil composition. The plant will be wet as the soil will dry out. It will prevent the surface of the Earth that have their organic matter composition nedescompusa (remnants of dried plants).
We achieve good results and then, When the water was literally wetting the herb we'll add Citramon or Ascofen (3-4 half gallon of water pill) or potassium permanganate (a few tiny, until water color light pink).
If the number does not decrease sciaridelor, It will resort to the use of an insecticide, for example: DIMILIN 25 WP (if incorporeaza compost 4,0 g/mp sau 40 g/m3), Actara, Mospilan, Dantop (It is enough that the soil in the pots should be soaked with a solution of one of these insecticides. It is recommended to not more than 3 chemical treatments with an interval of 7-10 days).
In the case of herbaceous African violetelor, in order to prevent the infestation of soil with such specimens, the soil will heat treat or opari. The seeds will be planted in pots sealed.
