Acarianul platRepresentatives Tenuipalpidae species closely related to spiders mites are, Actually they are called spider mites false.

We know about 40 representatives of this species , especially injurious to vines, Citrus, palm, Rose, Ficus and many other tropical and subtropical plants. Floricultorii meet with two species of mites pay: Brevipalpus if Tenuipalpus. Russilus Brevipalpus mite is a pest for cacti feared, instead affects orhideile and Tenuipalpus ferns. Orchid pests and mites are Brevipalpus oncidii and Brevipalpus obovatus.

I'll talk more about mite Brevipalpus obovatus, He is the main pest of African violets. This mite is known as flat red mite, orange flat mite, common flat mite, etc..
There are some tiny mites. Their size is 0.3 x 0.18 mm. The body is oval, strongly flattened red or reddish, covered with short perisori.

The male is smaller in size than the female. Unfertilized eggs and females can apply, of which will come later female. Eggs are purple and have luster. Their size is about 0.1mm.
Red mite larvae are pale purple, have three pairs of legs and are a bit larger than the egg. After the first stage of development, they turn into protonimfe, that as adults, have four pairs of legs and adults differ only in size. They are a little smaller.

After each stage of development, flat mite is in hibernation. Periods of sleep occupies 40% of the period of development of flat mite. Commonly, hibernating females and eggs.
Being able to sleep flat mite not successfully feed and support low temperatures, because of this many preparations used for its destruction does not take effect.
Flat mite inhabits predominantly African violets upper leaf juice feeding cells. It is impossible to see with the naked eye.

African Violets affected by the mite leaves have edges folded down flat, especially when humidity is low. Traces of mite flat are best seen on the leaves close to the root. Affected plants lose their decorative, surface shrinks and intensity of photosynthesis, no bloom, affected leaves wilt rapidly and easily detach from the strain, plant growth stagnates in. Plus all, violets are susceptible to infections and can die easily.
On streptocarpus flat mite occurs somewhat differently. Carefully examine the underside of the leaf, in the cells of the veins are a gloss of a specific oil stains. The leaf surface in these places are gofraza and gets a brownish. Gradually acquires a shade leaves begin to yellow and dry the edges.

The treatment plant is performed 3-4 times at intervals of 3-4 days.
The best preparation for the destruction of this parasite is APOLLO 50 SC. It is relatively harmless to human health and destroy mite flat even embryonic development stage.
Avoid browsing or using Actel preparation apartments. Spray solution evaporate and give off poisonous fumes that endanger the lives residents.
