Living habits of Liriomyza

The adult larvae are about 2 mm long; the larvae have a maximum body length of 3 mm and a grub shape. The adult uses an ovipositor to make a small mouth on the foliage of the plant, and absorbs the juice inside. The female lays the egg under the epidermis of the wound. The eggs hatch in 2-5 days, and the larval stage is 4-7 days. The terminal larvae bite the epidermis and pupate the leaves outside the leaves or under the surface. The larva turn into adult 7-14 days, 2-4 weeks in summer, and 6-8 weeks in winter.

Insecticides for controlling Liriomyza

Now insecticides applied on vegetables tend to low-toxic products, such as abamectin, lambda-cyhalothrin, bacillus thuringiensis.

However, solely using a kind of insecticide will result in resistance on crops, it would bring a better controlling effect if these products matched together and applied scientifically.
