What is aphid
Most of the fruit crops are subject to various diseases. this can be detrimental to crop productivity. Also, in addition to diseases, crops can be attacked by various pests, and the pear is no exception. The most dangerous pest is considered aphid. The main signs of aphid damage are: the shape of the leaves begins to change, curl, begin to dry out, the defeat of a sooty fungus begins, the shoots begin to change their color. Aphid has a different name - leaf roll. Aphids very often appear on the pear.
The pest spread throughout the country. But it is almost impossible to see one or two aphids due to its translucency and small size (only 5 mm). But the color can be different: either black, or even pink. A great danger is a colony of aphids, which completely covered the leaves or stems. During the summer period, their number can increase significantly, since one individual can lay up to 60 larvae. Therefore, the destruction of aphids on a pear in the summer is a popular activity among gardeners. If you look closely at the colony, you can see its heterogeneity, this is due to the fact that aphids of different ages and sizes are present in the colony.
If aphids appear on the leaves of a pear, you can see a sticky liquid on them, which flows directly to the ground. It is already being eaten by black ants. Those leaves that have been attacked over time lose their juiciness and light, begin to dry out, and the culture as a whole loses its frost resistance. they multiply quickly. After 15-20, the larvae can lay their eggs. By the middle of summer, the number of generations can reach up to 5-6 pieces. By this time, another form has already appeared - a winged one. They begin to migrate, flying from one culture to another, where they continue to reproduce. Groups form in the most juicy places: leaves, stems, inflorescences, buds. Aphids on pear leaves begin to suck out all the juice from them. A delay in growth and development begins. Flowers and ovaries begin to die off and fall off.
