Whiteflies have more than 1,500 species from families and subfamilies. They look like moths or butterflies, but only of extremely small size. The dimensions are 1.5 \u2014 2 mm, in some cases 3 mm. The body is usually yellow, but given the huge population of species, you can find white and yellowish-red with dark spots.

It is found all over the world, except Antarctica. It lives on more than 600 plants, while more than 200 of them are harmful. It is most often found on tomatoes, cucumbers and eggplants, although it is omnivorous by nature. Gerbera is a whitefly&#8217;s favourite plant. They prefer a warm climate, so they are not observed in the open ground in winter, unlike greenhouse conditions that are comfortable for them. It is dangerous for plants not only because it parasitizes it by eating juices. Whitefly secretes a fall that promotes the development of fungi on the plant. When feeding, it carries a secret into the plant that changes the normal physiological growth process. Visually, this can be expressed in yellowness on the leaves and stem, lead to irregular ripening and generally cause serious damage in the greenhouse. Among other things, it is a vector of viruses and a dangerous quarantine object. The import of plants inhabited by tbacco whitefly is prohibited by law in many countries.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"620\" height=\"465\" src=\"https:\/\/b-ento.com\/wp-content\/uploads\/2020\/10\/belokrylka.jpg\" alt=\"\u0431\u0435\u043b\u043e\u043a\u0440\u044b\u043b\u043a\u0430\" class=\"wp-image-1245\" srcset=\"https:\/\/b-ento.com\/wp-content\/uploads\/2020\/10\/belokrylka.jpg 620w, https:\/\/b-ento.com\/wp-content\/uploads\/2020\/10\/belokrylka-300x225.jpg 300w\" sizes=\"(max-width: 620px) 100vw, 620px\" \/><\/figure><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Greenhouse whitefly<\/strong><\/h3>\n\n\n\n<p>Greenhouse whitefly <em>(Trialeurodes vaporariorum)<\/em> is an extremely dangerous pest of tomatoes and vegetable crops in the protected ground (greenhouses). Unlike tobacco whitefly, it is not so demanding of heat and tolerates lower temperatures more easily. It is impossible to classify the harmfulness of an individual separately, since the harm caused is similar to the harm caused by other individuals of the species. Greenhouse whitefly is also a catalyst for the growth of fungi and a vector of viruses. It spreads mainly on the upper part of the plant, unlike tobacco, which can spread throughout the plant.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Controlling of whitefly<\/strong><\/h3>\n\n\n\n<p>Both species of whiteflies are extremely resistant to pesticides and adapt well to their different species. Therefore, before using them in a greenhouse, you need to think twice. It is quite possible that you will not achieve the expected result of destroying the parasite, and the damage to the plants will definitely be inflicted.<\/p>\n\n\n\n<p>The safest method of fight, which is the future of agricultural technologies, is the use of entomophages. Of course, this method, like any other, has its own difficulties and requires a competent approach. Its main advantage is the observance of the natural integrity of the growing process. After all, nature has already invented everything before us and there is a tamer for every pest.
