Environment protection type natural enemy insect collector

Abstract

The invention relates to an environment-friendly natural enemy insect collecting device, the structure of which comprises a moth collecting funnel, a moth collecting cage, a negative pressure box, an air intake duct, a blower, an air exhaust pipe, and a dust collecting bag, the moth collecting cage is arranged below the moth collecting cage in the negative pressure box; an air outlet is arranged at the upper portion of the negative pressure box and connected to an air inlet of the blower via the air intake duct; and an air outlet of the blower is connected to the dust collecting bag via the air exhaust pipe. When the collecting device collects intermediate host such as rice moth imago or gelechiid moth imago for natural enemy insect propagation, the imago moth on the cover of an incubator quickly enters into the moth collecting cage guided by the air flow, and the following moth spawn and dust are entered into different collecting locations to be separated effectively. The imago moth and the moth squama can not fly to cause environmental pollution so as to ensure the cleanliness of the moth propagation room and avoid the insect squama being contacted with the human skin or being inhaled into respiratory tract to cause untoward effect. The utility model is safe and suitable for environmental protection.

Description

technical field [0001] The invention relates to a device for collecting intermediate hosts such as rice moth or wheat moth adults used for the reproduction of natural enemy insects. Background technique [0002] The intermediate host eggs of natural enemy insects (egg parasitoid - Trichogramma) used for biological control of agricultural and forestry pests come from the eggs of Lepidoptera insects that reproduce in large numbers indoors, such as the eggs of rice moth or wheat moth. During the rearing of these insects, it is necessary to collect adults and place them in mesh cages to allow them to concentrate on laying eggs. During the collection process, adults of Lepidoptera insects will produce a large number of tiny scales due to alarm. The scales of these moths are light and small, and they are easy to fly with the wind. of good health. So far, no special device has been found that can treat insect scales. The method of collecting adults that is used more at home and ...

AI Technical Summary

Problems solved by technology

There are semi-mechanized methods in foreign countries, such as electric brush scraping or vacuum cleaners to collect adults. Due to the unavoidable flying scales in the operation process, and each has its own shortcomings, the manual slapping method and the glass bottle capture method are easy to make rice moths escape; the electric brush scraping method is easy. Scratching adults will affect the amount of eggs laid and their lifespan; the vacuum cleaner can only absorb one or a few adults at a time, and other adults will easily startle and run away

The common point is that the work efficiency is very low, and it can neither protect the environment nor adapt to the requirement of a large number of host eggs for breeding natural enemy insects
