Biological fight with beneficial insects


There biological struggle it is based on the use of useful animals to combat harmful animals. In gardening and agriculture, the biological struggle it can be done with ladybirds, chrysopes, carabids (not to be confused with cockroaches), arachnids (including mites), earwigs, ichneumonids, hoverflies and bedbugs.

In short, the biological struggle teaches us that beautiful and loved animals are not always good and ugly ones are not always bad. Spiders, for example, are very useful for taking care of the garden in a natural way because they are among the greatest hunters of parasites. And among the mites, incredible but true, there are useful species as well as harmful ones. While some butterflies can be terrible, just think of those of the boxwood defoliator caterpillar.

Some of the small beneficial insects in the biological struggle in the garden and in the vegetable garden they can be purchased in specialized centers or by mail order. Especially chrysopa larvae and ladybirds, for which you can also set up a bug hotel close to home (building it and buying it online), but also ichneumonids, hoverflies and predatory mites.

Shelter for ladybirds and chrysopes

The optimal use of these small animals is represented by greenhouses, winter gardens and verandas. In the case of ichneumonids (similar to wasps due to their thin 'waist'), it is also possible to think of use in the open field to contrast with the biological struggle the growth of caterpillars and lepidoptera.

Same thing for the predatory nematodes, filiform worms that crawl into the ground like eels (hence the nickname of eels) that can be purchased in larvae immersed in a particular substrate to be dissolved with water and spread on the ground.

The interesting thing about predatory nematodes is that they are highly specialized and affect only certain prey: grillot mole, mosquitoes and small snails. So the biological struggle it can be addressed in an 'intelligent' way by countering only certain threats but preserving the natural balance of the garden, vegetable garden or greenhouse.
