The technical scheme that the present invention adopts is: this benefit evil insect efficient separation method is: through light trap insect is collected in the collection worm case, collection worm case bottom has natural enemy escape hole, and the individuality of insect lepidoptera imago is bigger, can not creep; Beneficial insect ground beetle, rove beetle, predacious diving beetle, ladybug etc. then can be fled from through natural enemy escape hole in muddy water; On the device pedestal of collection worm case built-in case is installed, has planted seedling or fresh straw on the device pedestal of built-in case central authorities, built-in case is netted; Only allow entering such as little individual insect plant hopper, black porch green plant bug, mosquito; Most of plant hopper accumulates on seedling or the fresh straw, and the insect plant hopper also produces ovum on seedling or fresh straw simultaneously, and the black porch green plant bug is a food with the plant hopper ovum then; Equally; Beneficial insect in the collection worm case can eat up the most of insects in the inside, and insect is all dead after 3-5 days, and beneficial insect is all put back to the field.

This benefit evil insect device for effectively separating; Comprise collection worm case, device pedestal, built-in case, the top of collection worm case has the funnel type insect entry, and collection worm tank wall is surrounded by net; Built-in case tank wall also is a net; Built-in case is fixed on the device pedestal of collection worm case central authorities, and collection worm case bottom is connected with device pedestal top, and the junction is provided with several natural enemy escape holes.

In the technique scheme, be covered with the mud or the water of 1 cm thick on the device pedestal.

In the technique scheme, planted a strain seedling or a fresh straw in mud on the device pedestal of built-in case central authorities or the water.

In the technique scheme, collection worm case surrounds cylindrical shape by nylon wire or stainless (steel) wire, and built-in case surrounds cylindrical drum by nylon wire or stainless (steel) wire.

Basic principle of the present invention is to lure collection worm case to insect through fan sucking type high efficiency light trap light traps such as (Chinese patents 200910042916.2); The individuality of lepidoptera imago is general bigger; Beneficial insect comprises mainly how ground beetle, rove beetle, predacious diving beetle, ladybug etc. can creep in muddy water; Can flee from through natural enemy escape hole, device bottom, lepidoptera pest then can not; Built-in case also only allows little individual insect to get into, and like plant hopper, black porch green plant bug, mosquito etc., and the seedling or the fresh straw of central authorities have kind of an inducing action to plant hopper; Most of plant hopper then accumulates on seedling or the fresh straw in the collection worm case, and plant hopper also produces ovum on seedling or fresh straw simultaneously, and the black porch green plant bug is a food with the plant hopper ovum then; Equally; Beneficial insect in the collection worm case can eat up the most of insects in the inside, and insect is all dead after 3-5 days, then all puts back to the field to beneficial insect.

Advantage of the present invention: the first, breeding oophagous trichogrammae in the ancillary chamber.Lure the lepidopterous insects of collection to produce ovum on the nylon wire around the collection worm case through type light traps such as fan sucking type high efficiency light traps; Every lepidopterous insects can produce 100-200 grain ovum; Can lure 90-100 lepidopterous insects usual each evening; The insect pest peak period can lure 600-700 lepidopterous insects, and these Lepidoptera ovum can be bred 10,000 to 70,000 oophagous trichogrammaes, can save the oophagous trichogrammae kind in mu field, 1 mu of field to 7; That has reduced the field to a great extent puts the honeybee cost, has avoided the harm that brings in the insect pest peak period simultaneously.The second, the primary pest natural enemy in protection field.Insect collection box at the bottom to escape predators set up six holes, step A, paederus, ladybugs, Dytiscidae etc. from these holes to climb out; Furthermore, some beneficial insects can set insect pests box for food, while Cyrtorhinus bugs eat mainly planthopper eggs 3-5 days inside the pests all died before the completion of beneficial insects die back field, which completely avoids the insecticidal lamps of the "manslaughter", is conducive to the effective control of field pests , to prevent the occurrence of natural enemies of pests massive security.Therefore, the present invention should accelerate to promote, to solve the problem of preventing and treating of insect pest in the ecological agriculture production process.
