Problems solved by technology

However, there are also defects that the control effect is slow, especially when the population density of pests such as aphids is high, it is difficult to quickly reduce the population density, and chemical control must be used to quickly reduce the population density
Because chemical pesticides have a certain killing effect on natural enemies, it is difficult to release natural enemies and use chemical pesticides to control pests at the same time in the cultivation of vegetables in solar greenhouses. That is to say, the existing technology cannot realize the coordinated use of chemical control and releasing natural enemies
[0003] Existing chemical pesticides are mostly used through foliar spraying or root application. The contact between chemical pesticides and vegetable crops will inevitably cause vegetable pesticide residues
That is to say, existing chemical control has the defect that it is difficult to realize the non-contact chemical pesticide control of vegetable crops.

Embodiment

[0033] Embodiment, a kind of method for the synergistic prevention and control of aphids by Lacewing lacewing and imidacloprid, synchronously releasing Lacewing Lacewing and using chemical pesticide imidacloprid to control aphid damage during vegetable cultivation in a solar greenhouse;

[0034] Said lacewing, a biological natural enemy, preys on aphids;

[0035] The imidacloprid, a nicotinic high-efficiency insecticide, can kill aphids by contact.

[0036] The main process of releasing Lacewings is as follows: 7-10 days after vegetable planting, it is found that aphids begin to release Lacewings, 667 m 2 Press 300-400 heads, release once every 7-10 days, and release 2 times in a row.

[0037] The use of chemical pesticide imidacloprid is realized by hanging insecticidal boards, 667m 2 Evenly hang 30-40 insecticidal boards;

[0038] The insecticidal board is composed of plastic silk cloth, imidacloprid, maltol and chitosan, and the plastic silk cloth is 30-40cm long and 20-...

Abstract

The invention discloses a method for synergistically preventing and controlling aphids by chrysopa formosa and imidacloprid. The chrysopa formosa is released and the imidacloprid is used in a synchronous manner to control damage of the aphids in the cultivation process of solar greenhouse vegetables. The method disclosed by the invention can realize protection and utilization of the chrysopa formosa to continuously control the aphids, quickly reduce an insect population density of the aphids, has a good insecticidal effect, and can realize organic unification of biological prevention and control and non-contact chemical pesticide prevention and control of vegetable crops.

Description

technical field [0001] The invention relates to a method for synchronously utilizing Lacewing lacewing and imidacloprid to synergistically prevent and control vegetable aphids in solar greenhouses, belonging to the technical field of plant protection. Background technique [0002] At present, it is an indispensable green prevention and control measure to control aphids and other pests from vegetable cultivation in solar greenhouses. Occurrence and development, in the case of continuous use, it also has the advantages of continuous and lasting control of pests such as aphids. However, there is also the disadvantage that the control effect is relatively slow, especially when the population density of pests such as aphids is relatively large, it is difficult to quickly reduce the population density, and chemical control must be used to quickly reduce the population density. Since chemical pesticides have a certain killing effect on natural enemies, it is difficult to release n...
