Aphids on cucumbers

Aphids in cucumbers PhotoUsually, aphids, which can affect not only cucumbers, but also zucchini and pumpkin, can be observed already in July-August. As a rule, it has a dark green color, but there are kinds of black and yellowish color. In length it reaches 1,5-2 mm. Nutrition for her are plant juices, while the first signs of the presence of aphids are twisted leaves, the falling of flowers and ovaries. Aphid on cucumbers chooses as the place of settlement the underside of the leaves, as well as young shoots, flowers and ovaries, where they arrange whole colonies.

Destroy the pest by the same methods that are used to combat other species of aphids.

Often one can observe how the leaves of vegetables are dotted with a lot of these small insects - so the colonies look like, which can be represented by ten, a hundred or a thousand insects. In some cases, the colony can reach such a size that on each leaf you can see these insects.

Feeding for aphids are plant juices. If insects are present in large numbers, this will soon lead to depletion of plants and their death. As a result of damage to aphids, cucumber leaves are twisted and die. Suffer from the pest and shoots: in the beginning, their curvature occurs, after which the growth stops, the aging deteriorates and ends with the drying of the vegetable crops. In the beginning of life for aphids, wild crustaceans serve as food, but with coarsening leaves of these plants insects pass to garden crops.

To achieve a significant reduction in the population of aphids that have affected vegetable crops, you can, without resorting to chemical means of struggle. Other insects, ladybirds, can help here. In order to attract these useful insects, they plant dill and mustard on the beds. In the spring of the ladybirds you can find yourself: their favorite place is the wild flowers.
