Information

Winter is the critical period for greenhouse vegetable planting, and the greenhouse planting mode and the traditional farmland planting mode are very different in environmental conditions and equipment conditions. A closed environment such as a vegetable greenhouse is easier to provide breeding and growth conditions for pests! Therefore, I will introduce the prevention and control techniques of common greenhouse pests: 

1. Liriomyza

Pest Information:

 

Liriomyza, also known as ghost painting symbol, belongs to the Diptera Liriomyzae pest. Mainly damage more than 110 plants in 22 families, including cucumber, tomato, eggplant, pepper, cowpea, broad bean, soybean, kidney bean, watermelon, wax gourd, and loofah.

Prevention Method:

Agricultural prevention and control: Clean the garden, remove weeds and sick plants in time, and reduce the source of insects.

 

Physical prevention and control: The adults of Liriomyza are traped and killed by using the Yellow Board, to reduce the density of insect population in the field. For open field or greenhouse cultivation, the Jiaduo Yellow Board can be inserted twice during the peak period of the occurrence of Liriomyza in April-June and August-October, and 25-30 pieces/mu are inserted according to the size of 20cm×40cm. To a certain extent, It can reduce the density of field pests and control the damage degree of Liriomyza.Physical prevention and control: According to the size of 20 cm × 40 cm per mu of land, 25-30 pieces of Jiaduo Yellow Boards are inserted in the field to trap and kill adults. And the Yellow Boards inserted into pieces have a certain control effect on aphids.
