If design, a kind ofly can make most of beneficial insects escape from collection worm bag or collection worm case, and insect can not pass through, to reach, to protect the go out device of harmful effect of benefit particularly important.
Summary of the invention
The purpose of this utility model aims to provide a kind ofly can effectively control pest control, protect beneficial insects by light trap, do not manslaughtered for the light trap device that protects beneficial insects.
The implementation of the utility model purpose is; a kind of light trap that can protect beneficial insects; the collection worm pocket type of the peripheral electrical network of light trap pipe or the box light trap of collection worm; funnel is arranged at light trap base top; light trap base bottom connects collection worm bag; collection worm upper box part has funnel, on light trap base bottom and collection worm bag joint portion side plate, narrow slit type emergency exits or eyelet formula emergency exits is arranged, and collection has narrow slit type emergency exits or eyelet formula emergency exits on worm upper box part side.
The utility model is comparatively indomitable according to some beneficial insect vitality, in the photoreduction process that becomes, by electrical network, is hit dizzy collection worm bag or the collection worm case of falling into, and after a period of time, can come to life; The vitality of the beneficial insect such as predatism or parasitic insect is more indomitable, there is the stronger ability of creeping and individual little, after falling into collection worm bag or case, habituation is upwards creeped, can utilize self build advantage to escape from from emergency exits, according to Morphological Differences between different insects and behaviouristics difference, at the light trap base or lure on the worm case and be designed with narrow slit type emergency exits or eyelet formula emergency exits, guarantee that most of beneficial insects can escape from collection worm bag or collection worm case, and insect can not pass through, to reach, protect the beneficial harmful effect of going out.
The utility model processing is simple, substantially without extra, drops into, and does not affect the effect of insect-killing trapping, can significantly reduce the trapping quantity of light trap beneficial insect, if apply in various light trap, can protect to greatest extent natural enemy insect, maintaining ecological balance.

Embodiment
The good many PS15-II type frequency ventilating type light trap of below take is example, with reference to accompanying drawing in detail, the utility model implementation process is described in detail.
With reference to Fig. 1,2, there are light trap pipe 1, the peripheral electrical network 2 of light trap pipe in the light trap base top of collection worm pocket type light trap, and funnel is arranged at light trap base top, and light trap base bottom connects collection worm bag 6.There are light trap pipe 1, the peripheral electrical network 2 of light trap pipe in collection worm case 9 tops of the box light trap of collection worm.On light trap base bottom and collection worm bag joint portion side plate, narrow slit type emergency exits 5 or eyelet formula emergency exits 7 are arranged.
The long 15cm of narrow slit type emergency exits 5 narrow slit, wide 0.5-0.8cm.The eye diameter of eyelet formula emergency exits 7 is 0.5cm.
With reference to Fig. 3,4, there are light trap pipe 1, the peripheral electrical network 2 of light trap pipe in collection worm case 9 tops of the box light trap of collection worm, and there are solar panels 8 light trap pipe, electrical network top, and collection worm upper box part has funnel.Collection has narrow slit type emergency exits 5 or eyelet formula emergency exits 7 on worm upper box part side.
The wide 0.5-0.8cm of narrow slit type emergency exits 5 narrow slit.The eye diameter of eyelet formula emergency exits 7 is 0.5-0.8cm.
Emergency exits width of the present utility model, eye diameter adopt 0.5-0.8cm, are according to multiple ladybug, tiger beetle, small-sized ground beetle, parasitic wasp, Chrysopa, hunt the body size decision of the beneficial insects such as stinkbug, earwig.In using light trap insect-killing trapping process, because Some Insects vitality is comparatively indomitable, in the photoreduction process that becomes, by electrical network, hit dizzy collection worm bag or the collection worm case of falling into, after a period of time, can come to life.The insect of agriculture and forestry plant of causing harm is the insects such as lepidopterous noctuid, hawkmoth, snout moth and some micropterygid classes mostly, the major way of their motions is flight, because the space of collection worm bag or case is little, will collide collection worm bag or tank wall after taking off and fall into bottom, they want that the chance of escaping by emergency exits is very little.Other agricultural important pests is as very capable in longicorn, chafer, flatheaded borer etc. creep, but, because individuality is larger, can't pass through emergency exits.The vitality of the beneficial insect such as predatism or parasitic insect is also more indomitable, as multiple ladybug, tiger beetle, small-sized ground beetle, parasitic wasp, Chrysopa, hunt stinkbug, honeybee, earwig etc., there is the stronger ability of creeping and individual little, after falling into collection worm bag or case, habituation is upwards creeped, and can utilize self build advantage to escape from from emergency exits.
The insect that the other build is less is (as wing purpose plant hopper, leafhopper, the termite of Isoptera) often vitality is more fragile, afterwards will soon be dead by the electrical network electric shock, even hit dizzy collection worm bag or the case of falling into, collecting also death very soon under worm bag or case anoxic, hot environment, so this class pest also can't be escaped from from emergency exits.
While using the utility model, the cleaning more than 3 days of turning on light often once collects worm bag or case, beneficial insect can successfully escape from from emergency exits during this period, the insect that build is larger can not pass through, weak directly electric shock of the common vitality of some mini pests and dead or fall into collection worm bag or case is dead under the high-temperature low-oxygen environment.Therefore reach the effect protected beneficial insects.
The size of emergency exits can lure the worm kind to be regulated according to locality, under the principle that guarantees pest control, more beneficial insects can be escaped.
