Method for preventing and controlling greenhouse vegetable aphids

Abstract

The invention discloses a method for preventing and controlling greenhouse vegetable aphids and belongs to the technical field of horticultural cultivation. The method for preventing and controlling greenhouse vegetable aphids comprises the steps of cultivating thick growth of Artemisia argyi; releasing Coccinella septempunctata or Chrysopa perla; planting crops; hanging yellow insect-sticking boards; and harvesting the crops. According to the invention, aphids are prevented and controlled through the co-action of Artemisia argyi, Coccinella septempunctata or Chrysopa perla and the yellow insect-sticking boards; specifically, aphids are attracted to tender leaves of Artemisia argyi through sitotaxis of the aphids to the tender leaves of Artemisia argyi, Coccinella septempunctata or Chrysopa perla is released to prey on the aphids, and the yellow insect-sticking boards are hung above the Artemisia argyi so that the winged aphids are attracted to the yellow insect-sticking boards and cannot escape through characteristic of the aphids moving in response to yellow. The co-action of the Artemisia argyi, Coccinella septempunctata or Chrysopa perla and the yellow insect-sticking boards brings good aphid control effect, crops can be prevented from being damaged by aphids, the population density of aphids in a field can be rapidly and effectively reduced, pesticide residues and aphid drug resistance cannot be caused, and physical and biological aphid control is achieved.

Description

technical field [0001] The invention relates to a method for preventing and controlling vegetable aphids in greenhouses, and belongs to the technical field of horticultural cultivation. Background technique [0002] Aphids, also known as greasy insects and honey insects, are a class of herbivorous insects, including all members of the Aphidoidea. There are about 4,400 species of aphids that have been discovered in 10 families, most of which belong to the family Aphididae. Aphids are also one of the most destructive pests on earth. Aphids can cause direct damage by sucking the juice of leaves, stems, tender heads and young ears, and can also cause indirect damage by spreading viral diseases. Greenhouse vegetable aphids include several types of aphids that damage vegetables. One is cabbage aphids, also known as radish aphids and vegetable aphids. Mustard greens, cabbage, cabbage, cauliflower, turnip and other cruciferous vegetables, especially cabbage and mustard greens, da...

Problems solved by technology

The other is melon aphid, also known as cotton aphid, which mainly damages melons and solanaceous vegetables. Adults and nymphs suck plant juice on the back of leaves and tender stems. When young leaves and growing points are damaged, the leaves shrink and the plants wilt , or even die; the old leaves are damaged and withered early, shortening the fruiting period, resulting in reduced yield

[0003] At present, in the production of greenhouse vegetables, the method of spraying pesticides is usually used to kill aphids, which will cause drug pollution of crops, and will consume manpower and high expenditure costs. Moreover, using pesticides to kill aphids for a long time will cause aphids to develop drug resistance.
