Greenfly

The insect belonging to Aphididae family, order Ц homopterans. More than 200 types are found. There is a green and black one, flying and apterous, etc. It is probably the least harmless pest in the indoor crop of citrus plants. The greenfly is well-known. These are small tender insects that usually sit in big colonies. They always sit on young sprouts and suck out all the sap from them (such stinkers). The greenflies often cause the deformation of leaves (which sometimes leads to ruptures) and curvature of ends of sprouts. Many greenflies excrete sweet frass in the form of a drop on the bum, therefore they are willingly visited by ants which are nourished by these excretions. But they donТt eliminate the greenflies. The greenfly as well as the thrips can be a disease carrier. Greenfly control lies in crushing them with hands. In case it doesnТt help one should spray it with any chemical (except acaricides). Any kind will do actually or a folk remedy. Citrus nematode Tylenchulus semipenetraus Citrus nematode is a very small milky-transparent worm. It gnaws through the roots of the plant, crawls inside and sucks on the sap of the plants. Contamination happens unnoticeably, after some time the gardener notices that there is something wrong with the tree... the leaves start falling. He digs the plant out for inspection and sees large swellings on the roots. The nematode lives in these УpotatoesФ. Citrus nematode is found in areas where the citrus plants grow in open ground. It can get into the pots and containers only from a bad fruit nursery situated in the warm lands. Citrus nematode can be very rarely found in Russia and Canada. I donТt have any information on its area of distribution in other countries. Outwardly these worms resemble the ordinary nematode and the ordinary one does not harm the citrus plants. The simple nematode eats rotten organic residues like earthworms. Earthworm It is often found in the ground. It is not a pest and doesn't cause much trouble. But still it is better to take all the worms out before planting. Quite the opposite thing is recommended in many handbooks: worms loosen the ground and fertilize it therefore they are useful; however I keep to my point of view. Yes! Worms are useful for the garden, but the negative effect can take place in the pot culture. I will write why it is so in more details after the completion of experimental research. Trips Greenhouse Thysanoptera The photos are very beautiful, жирненький...(¤ извин¤юсь, но не смогла перевести) and I want to eat. In the home looks like a dark line on the page. Not immediately understand what it is. Pests successfully натурализировались from South America to Europe. And gradually moved to the north. Fortunately our climate for them холодноват, and in winter they were almost all destroyed by frost. Therefore, we call them “епличными Thrips. And only in greenhouses they feast full swing! Thrips - it-sucking insects that feed on the juices of the plants, nectar and pollen. Especially love plum, carnation, roses, tomatoes, strawberries, well and lemons. The adults are 1.5-2 mm in length. The photographs of a male and a female is gray. But the color is still depending on the species and on the climate, if wet male darker. Thrips not so much to eat, how much shit. They know how to fly and are almost the most important carriers of disease. The struggle - tree wash in the shower. Are sprayed with insecticide 2-3 times with an interval of 15 days. In the industrial greenhouses with thrips is usually confronted with the help of predatory mites. Say helps and brimstone color. The photo has been increased in 100 times.
