Problems solved by technology

Neuroptera is a very good biological control resource, and the brown fly insects are still a blank in this respect. The inventor has proposed a method of using aphids to raise the horned vein brown fly (Micromus angulatus Stephens) through a large number of research experiments during his doctoral period. The laboratory method, which is not ideal in terms of egg production, egg hatching rate, larvae predation, adult eclosion rate, etc., the inventor further optimized the breeding method, combined with the occurrence of greenhouse flower pests characteristics, put forward the method of using the brown fly to control greenhouse flower pests, and provided technical support for the biological control of greenhouse flowers

Embodiment 1

[0025] 1. Test method: (test repeated three times)

[0026] (1) 50 plates of soybean seedlings with 2-3 true leaves are moved to the aphid breeding room, and each soybean seedling is inoculated with 5 soybean aphids. Standby after 7 days;

[0027] (2) move the adult of the female brown gnat to be laid eggs into the raising box, the raising box is a transparent plastic box, 20cm long, 12cm wide, and 7cm high; half of the box cover is reserved, and the other half is covered with gauze, and the gauze The aperture of net is 0.15mm; Put the soybean aphid raised in step (1) together with a small amount of soybean seedling branches and leaves together in the breeding box, and the amount of soybean aphid fed by each brown fly adult is 30-45 head / day, prepare 30 breeding boxes, each of which has 1 adult female brown fly gnat waiting to lay eggs;

[0028] (3) After the female brown fly adult began to lay eggs, the collected ovum was moved into an empty rearing box, and the amount of e...

Abstract

The invention discloses a method for preventing and treating greenhouse flower insects by using brown lacewing. By optimizing the reproductive conditions of micromus angulatus, the egg laying amount, the egg hatching rate, the larva capturing amount and the imago eclosion rate of the micromus angulatus can be remarkably increased, furthermore the effect of preventing and treating greenhouse flower insects by using the micromus angulatus can be improved, and technical supports of biological prevention and treatment can be provided for greenhouse flowers.

Description

technical field [0001] The invention relates to the technical field of biological control of agricultural pests, in particular to a method for controlling pests of greenhouse flowers by using the brown fly. Background technique [0002] With the gradual expansion of flower market demand, greenhouse has become the most important and widely used way in flower cultivation. While it provides a suitable growth environment for many flower plants, the problem of pest control is also accompanied. Environmental conditions such as high temperature, high humidity, and insufficient air circulation in the greenhouse lead to the occurrence of various types, large numbers, serious damage, rapid spread, and frequent annual occurrences of greenhouse flower pests and diseases, making the prevention and control work difficult. Due to the high incidence of plant diseases and insect pests in greenhouse flowers, if only pesticides are used for control, it will not only increase the cost, but als...
