Description

A kind of rice moth raising device of applicable propagation in scale

technical field:

The utility model discloses a kind of rice moth raising device of applicable propagation in scale, is the improvement to existing rice moth raising device structure, belongs to agricultural technology field.

technical background:

Rice moth is Lepidoptera Galleriidae insect, and rice moth egg raises the high-quality feed of insect and the good hosts of breeding oophagous trichogrammae such as stinkbug, Chrysopa, thrips as a kind of, and the development for China's field of biological control has played important effect.Oophagous trichogrammae is used to a large amount of parasitic wasp producing and discharge at present in the world the most widely, utilize oophagous trichogrammae to prevent and treat the area of agricultural and injurious forest-insect more than 32,000,000 hectares in recent years in the whole world, and China puts honeybee to control one of maximum country of worm area in the world, therefore how to realize batch and produce oophagous trichogrammae in high quality, be the direction that many biological and ecological methods to prevent plant disease, pests, and erosion workers make great efforts always.At present, China factorial praluction oophagous trichogrammae is mainly host with egg of oak silkworm, breeding kind is only limitted to trichogramma dendrolimi and Trichogramma chilonis etc., and some excellent oophagous trichogrammae honeybee kinds such as trichogramma evanescens, Trichogramma Ostriniae, Trichogramma etc. can not well be utilized because it can only be bred with ovule (rice moth egg or gelechiid ova etc.).At present, the technology for rice moth is reported mainly with raising method and becomes moth collection utensil to be main.As " a kind of technique of mass rearing grained moth ", number of patent application be 99111515.5 with " a kind of environment-friendly type rice moth becomes moth gathering machine ", number of patent application is 201010265859.7, outside collection link, still lacks the breeding facility designed for rice moth growth and development characteristics specially.Mainly gather materials on the spot in existing raising, application tub or plastic square basin, oneself make some lids of processing and carry out raising and collecting.Use this kind of breeding facility to raise rice moth and there is wasting space, be unfavorable for the shortcoming of ventilation and heat, feed is easily mouldy simultaneously, and then affects growing of rice moth, can not meet the needs carrying out natural enemy insect propagation in scale.

summary of the invention:

The purpose of this utility model is the rice moth raising device providing a kind of applicable propagation in scale, improves rice moth rearing conditions, improves breeding spaces availability, is beneficial to expand cultivation scale, increases rice moth egg output.

The rice moth raising device of a kind of applicable propagation in scale described in the utility model, is characterized in that: be made up of fence, catch, box body, and body is at the bottom of upper base, sieve aperture and three layers of box body structure of going to the bottom, and upper base and body are drawing and pulling type syndeton; The top of body is provided with rectangular fence, and the four sides outer wall of fence is provided with the ventilating opening of fence type; Several catch are mutually arranged in a crossed manner in fence, form multiple little lattice; Catch is uniformly distributed pin hole air vent.The bottom at four angles of described fence is equipped with projection.

When raising rice moth, skim feed is spread in upper bottom portion of the present utility model, rice moth egg is sprinkling upon on feed uniformly, spreads one deck feed uniformly more afterwards, plug catch, plastic basin and the tub surface area of contrast formed objects can increase by 1.9 times, after 15d, first time feeds, and feeds once, until rice moth pupates every 2-3 days later, when rice moth pupates, can neat be arranged in little lattice that catch separates.When using general plastic basin or tub (40*30*20cm) to raise rice moth, rice moth 40 box can be raised for 1 cubic metre, collect rice moth egg 1000-1300ml, and when utilizing this device to raise rice moth, can raise rice moth 182 box for 1 cubic metre, collect ovum 4550-5915ml, feeding efficiency improves 4-5 doubly.

Good effect of the present utility model is: utilize this raising device to raise rice moth, and it is convenient to raise, well-ventilated, internal surface area is sufficient, is conducive to the growth of rice moth and pupates, and can stack in order when producing in batches, effectively can save space, improve the reproductive efficiency of rice moth.

Fig. 2 is body construction schematic diagram of the present utility model;

1, fence; 2, catch; 3, pinhole vent; 4, protruding; 5, body; 6, pull groove; 7, upper base; 8, at the bottom of sieve aperture; 9, go to the bottom.

embodiment:

Shown in accompanying drawing 1, Fig. 2, a kind of rice moth raising device of applicable propagation in scale is made up of fence 1, catch 2, box body 5, body 5 is upper base 7, at the bottom of sieve aperture 8 and 9 three layers of box body structure of going to the bottom, the top of body 5 is provided with pull groove 6, and upper base 7 forms drawing and pulling type syndeton with by pull groove 6 and body 5; The top of body 5 is provided with rectangular fence 1, the four sides outer wall of fence 1 is provided with the ventilating opening of fence type, and ventilating opening is opened in distance bottom 1cm eminence, and by inboard, expansion change is large gradually laterally, to ensure that rice moth small grub can not be escaped, be convenient to ventilation and heat when rice moth grows; Catch 2 is made up of long 3 catch and wide 5 catch, and length and width catch intersects to form 24 little lattice mutually to increase surface area, mutually arranged in a crossed manner in fence 1, forms multiple little lattice; Catch 2 is uniformly distributed pin hole air vent 3, is beneficial to and raises box inner ventilation, avoid when rice moth is raised and mutually rob food between individuality, be conducive to population growth; The larva initial stage, (0-20d) was raised by upper base 7, after 20d, upper base 7 is extracted out from pull groove 6, to transfer at the bottom of sieve aperture 8 to and raise, 8 times 0.5cm eminences at the bottom of sieve aperture, for going to the bottom 9, extracted out by upper base 7, at the bottom of sieve aperture, the worm excrement of rice moth larva directly can drain to and goes to the bottom 9 by 8, a large amount of worm excrement can be avoided like this to be mixed in feed, make feed mouldy, after rice moth has been raised, clear up in the lump.

The bottom at four angles of described fence 1 is equipped with protruding 4, together with can stacking, saves space for box with box.

When raising rice moth, skim feed is spread upper base 7, rice moth egg is sprinkling upon on feed uniformly, spreads one deck feed uniformly more afterwards, plug catch 2, plastic basin and the tub surface area of contrast formed objects can increase by 1.9 times, after 15d, first time feeds, and feeds once, until rice moth pupates every 2-3 days later, when rice moth pupates, can neat be arranged in little lattice that catch 2 separates.When using general plastic basin or tub (40*30*20cm) to raise rice moth, rice moth 40 box can be raised for 1 cubic metre, collect rice moth egg 1000-1300ml, and when utilizing this device to raise rice moth, can raise rice moth 182 box for 1 cubic metre, collect ovum 4550-5915ml, feeding efficiency improves 4-5 doubly.
