Annoying pink beetles hinder crop growth and let fierce lacewings help! It seems that the tiny lacewings are strong in feeding on whiteflies, shell insects, aphids and leaf mites, and many farmers intend to buy lacewings eggs or larvae to replace pesticide application, but they suffer from the high cost. They are also worried that the lacewings will fly away after eating their natural enemies and take a short time to apply them, so they have to keep spending money on egg tablets, and the promotion effect is not good.

In order to enhance farmers' willingness to use it, the Miaoli improvement Farm of the Council of Agriculture (hereinafter referred to as "Miao to Farm") is expected to launch automation equipment to reduce the cost of artificial breeding of lacewings, so that farmers will not be surprised. At the same time, a teaching manual will be produced to introduce the correct application methods and control results, and to promote biological control of natural enemies to replace the original use of pesticides.

Lacewings are ferocious and capable of controlling two-spot leaf mites, aphids and mites.

Lacewings are omnivorous insects, which are predatory natural enemies in biological control materials. They can eat whitefly, shell insects, aphids and leaf mites, and are suitable for strawberries, melons and fruits and other crops. Although the Chrysopa moschata larvae are so small that they are almost invisible to the naked eye, the pink beetles and leaf mites that are larger than them can be "intraplate mites." as long as they are targeted by them, they can only allow their paralyzed bodies to be sucked by the lacewings until the "liquid stem worm dies".

"Strawberries, papayas, grapes, lotus fog, and cucumbers are all used by people," says Zeng Yufang, the commissioner in charge of ─ Yoshida Company, which sells natural enemy control materials in Taiwan. About 10% of the farmers in Taiwan currently use lacewings, of which about 10% are organic farmers. The rest are farmers who switch to production and marketing experience or use facilities to cultivate them, and even residents who use vegetable gardens on their balconies at home.

It has been shown that lacewings can be used to prey on crops that are prone to two-point leaf mites, aphids, and pink shell insects. Many farmers say that in response to the current trend of drug reduction, lacewings can save manpower and pesticides, and are easier to use than pesticides.
