Chrysopas: How They Help in Your Garden
When we talk about beneficial insects for our garden, the image of ladybugs always comes to mind.
These are very beautiful insects and, in addition, keep harmful pests of ornamental crops or plants at bay. However, they are not the only ones. Another species that perform the same work and whose presence should rejoice us is crisp. If you have never heard of crisis, this is your article.
Greens and winged
The green lacewings are some insects belonging to the family Chrysopidae having veined wings. Although there are more than 1500 species all over the world, in general, they are usually green, medium-size and huge transparent wings.
They are very common insects in North America and also in all areas of Europe. They usually live near crops, gardens and, of course, in the countryside. They move during the night and that is when they move attracted by the light.
Some of them feed on molasses, nectar, and pollen, and others acquire the role of predators of many species of insects, which makes them feel attracted by orchards where there is the presence of pests.
An agricultural use
The green and brown crisopas are very well considered in matters of biological control of pests worldwide. This is because it exerts a natural control over numerous species of insects that are harmful to crops and plants.
In fact, crops and their larvae are marketed for this purpose. His method of action is as follows:
- First, we must bear in mind that larvae are always cannibals. When they detect their prey by direct contact, they ram and impact the insect.
- By injecting enzymes into their prey through the jaw, they kill the insect before sucking inside.
- This insect is known as the aphid lion since it can eat up to 200 insects a week. However, in addition to aphids, it also feeds on any soft body insects, such as mites, thrips, mealybugs, etc.
How to keep them close
Although in their adult phase they feed on branches and trunks of crops, the crops do not eliminate nutrients nor are they a gateway to viruses and diseases, so in their adult phase, they do not represent any danger.
However, in their larval phase, as we have said, not only do they not endanger our crops, but they protect them. Therefore, we are interested in keeping them in our garden. These are some methods to have them close:
- The abundance of vegetation and humidity are factors that help them feel good. Therefore, it is difficult for them to decide to stay if you do not have either.
- The crops are attracted to the light, so leaving some lights or lanterns lit at night may get your attention.
- Like all insects, crops prefer to take refuge in small houses or the well-known insect hotels that you can buy or make yourself.
- Finally, remember to respect their cycle and that of their larvae. This also refers to not using insecticides or toxic products that could damage them as an alternative or complementary treatment. The crisps themselves are already working against your pests, so using another extra treatment could scare them or make them stop feeling good.
