Harm

The usual aphid attack time is the second half of the summer, since the pest begins active reproduction in July. Located in the colonies on the underside of the cucumber leaves, the melon aphid feeds on juice (in more detail about what aphids feed on in nature, you can find out here).

The bushes begin to lose strength, the leaves turn yellow and curl, the growth of cucumbers slows down. Not less harm to cucumbers does black aphid. Voracious family affects almost all parts of the plant:

stem;
foliage;
inflorescences;
ripening fruits.

A young plant, attacked by a colony of aphids, is not able to develop and give the ovary. Most of the cucumbers die.

Cucumbers suffer from the aphid invasion not only in the open field, but also in the greenhouse. Insect excreted, sugary juice (pad), glues cucumber leaves and is a good bait for other garden pests.

Where does it come from and why?

Adults of aphids do not tolerate frost, but its larvae can survive the winter. For winter conditions, the pest usually selects weeds. The most comfortable place for nesting is basal leaves. Together with contaminated soil, aphids can get into the greenhouse.

Ants living in symbiosis with aphids also contribute to the survival of aphids. Insects can coexist both in anthills and in the nests of ants, which they arrange in greenhouses and greenhouses (for more information about the symbiosis of ants and aphids, you can find in this material).

In order for the aphid to start waking up from a winter sleep, it is enough to raise the air temperature to the mark of +5 degrees. Insects actively breed, feed on grass. By the time the cucumber seedlings are planted, the aphid is moving into a new stage of development - it has wings. Having acquired flight qualities, colonies of aphids go in search of fresh food. Young cucumber planting - a tasty morsel in the diet of pests.

Ants contribute to the further spread of wingless aphids along vegetable plantations.. They are attracted to sugary juice.

Chemical and biological

What and when to process cucumbers? It is possible to add chemicals only in the period when there are no cucumber ovaries. Industrial products are toxic to bees, so they should not be used during pollination.

The most effective chemicals include:

Commander - water soluble concentrate.
Corado - effective against aphids and colorado beetles. The protective effect after treatment lasts another 3-4 weeks.
Aktara - already on the second day after spraying the pests die. For new insects, plant juice becomes poison.

You can also use Peretrium, Inta-Vir, Spark Bio, Fitoverm. Biological methods consist in attracting other insects - the enemies of aphids. This option will be more effective for preventive purposes. For example, if a small peat slides are spread around a plot, it will attract gall midges that love to feast on. By planting dill or mustard on the beds, you can attract a ladybird - a natural enemy of aphids.
