Problems solved by technology

[0004] At present, there are still many deficiencies and defects in the application of commercial lacewings in the cultivation of vegetables in solar greenhouses. The main manifestations are: (1) The speed of killing insects is slow, and it is difficult to quickly suppress the population of insects
The light time for vegetable cultivation in solar greenhouses is short, and the number of eggs laid by adults of Lapis lacewings is reduced. After the release of commercial Lacewings products, it is difficult to establish a population with a large enough population in the solar greenhouse, which affects the control effect on Bemisia tabaci; ( 2) Large dosage and high cost
In order to achieve the ideal control effect, it is necessary to release a large group of commercial Lacewing products, resulting in high control costs, farmers are unwilling to accept it, and it is difficult to promote in production; (3) Lacewings are difficult to recycle after release
The use of commercial Lacewings to control Bemisia tabaci has not yet achieved the recovery and recycling of Lacewings

Embodiment Construction

[0035] This embodiment is to facilitate the understanding of the present invention without limiting the claims and core content of the present invention in any way.

[0036] Example, Such as figure 1 As shown, a method for preventing and controlling Bemisia tabaci in facility vegetables, comprising the steps of selecting control facility: selecting square plastic flowerpot 1, cultivation substrate 2, wheat seedling 3, insect-proof net 4 and supplementary light 5 to form propagation and recovery The integrated device of Lacewing and Vegetable Bemisia tabaci used in the prevention and control facilities of Lacewing; plastic flowerpot 1 is 50cm high and has a volume of 0.18m 3 An incandescent lamp with a rated voltage of 1.5 volts and a power of 0.5 watts is arranged on the uppermost end of the inner wall of the plastic flower pot 1 as a supplementary light 5; the plastic flower pot 1 is filled with a cultivation substrate 2 composed of peat and vermiculite at a ratio of 3:1, ...

Abstract

The invention discloses a method for preventing and treating greenhouse vegetable bemisia tabaci through chrysopa formosa brauer. A plastic flowerpot, a culture medium, wheat seedlings, a fly net and a light supplementing lamp are selected for forming an integrated device, and therefore chrysopa formosa brauer expanding propagation and recycling and bemisia tabaci preventing and treatment are achieved. According to the method, a chrysopa formosa brauer population which is suitable for production and is large enough in group number is built through small-group chrysopa formosa brauer expanding propagation; after the chrysopa formosa brauer population is released, the field environment adaptability is high, the bemisia tabaci predation rate is high, the bemisia tabaci population density can be effectively reduced, and the preventing and treating effect can be higher than 85%.

Description

technical field [0001] The invention relates to a method for preventing and controlling Bemisia tabaci of vegetables in facilities, in particular to a method for multiplying and retrieving Bemisia tabaci in plants and belonging to the technical field of biological control of vegetables. Background technique [0002] Lacewing is an important predatory natural enemy of many pests. It has biological characteristics such as wide distribution, large predation, and strong fecundity. It is a natural enemy insect with broad development and utilization prospects. [0003] The biocontrol technology using natural enemy insects to control pests has become a powerful measure to ensure the development of green agriculture in my country. There are many reports on the development and utilization of Lacewings at home and abroad. Lacewings are holometabolous insects. They have four different forms in their life: eggs, larvae, pupae, and adults. Lacewings in the egg and pupae stages cannot fee...
