Background
Diptera of Diptera, Trypetidae, Bactroceraceae, Dacinae, subfamily Oligocarpic. The adult bactrocera dorsalis lays eggs in host fruits, the larvae eat pulp in the fruits and develop and grow, the larvae jump out of the fruits after being mature, merge into soil for pupation, and the adult flies eclose in the soil. Fruit may be damaged by bactrocera dorsalis larvae, which may cause fruit drop or loss of economic value, and areas with severe occurrence of the larvae may cause crop outcrop, or yield loss of crops of more than 80%. In order to reduce the harm of Bactrocera dorsalis to fruits and vegetables, scientific researchers need to raise Bactrocera dorsalis for research. The artificial feeding of bactrocera dorsalis is carried out by putting ova into a container with feed for hatching, taking feed from hatched larvae and developing to grow, transferring the bactrocera dorsalis into soil or sand bed for pupation after the bactrocera dorsalis grows to mature larvae. And the fodder of raising the larva generally has certain viscidity, and the bactrocera dorsalis larva likes to bore simultaneously and climbs, and it is troublesome that the manual work separates larva and fodder, and injures the larva easily.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a little fruit fly mature larva collection device to overcome the difficult defect of collecting of little fruit fly mature larva.

After the larva of bactrocera dorsalis grows to old maturity, the fodder of raising the larva of bactrocera dorsalis falls to placing the frame, and the mature larva of bactrocera dorsalis likes to bore and climbs, and the hole that creeps can be followed from the small opening to the brill in-process of climbing, drops in the filter screen of below, climbs in the collection box of filter screen below again. When in use, the transfer box is placed with sterilized wet sand or wet soil for guiding the aged larvae to enter soil and pupate. The aged larvae will climb through the transfer pipe into the transfer tank under the guidance of the moist sand. The number of larvae is counted by a counter as they pass through the transfer tube. The filter screen can be arranged to further isolate the dropped feed.
Furthermore, the bottom of the placing frame inclines to one side, and a flow collecting groove with a water outlet is arranged below the lower side of the bottom of the placing frame. Is beneficial to the collection of the juice in the feed.
Further, place the frame both sides and be equipped with the card limit of outwards buckling, card limit detachably card is located on the edge of placing the frame top.
Furthermore, a guide plate is arranged in the collecting box below the filter screen, and the guide plate inclines to one side of the transfer hole. Is favorable for transferring the larva to the transferring box.
Furthermore, the transfer pipe is arranged from one end of the connecting hole to one end of the transfer hole in an inclined and downward mode. The transfer of the larvae into the transfer box is facilitated.
Further, the transfer tube is transparent. Facilitating the observation of the transfer of the larvae.
Further, 3-5 cm disinfected wet sand is paved on the transfer box.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the utility model discloses combine the old and mature larva of little fruit fly of tangerine to like the habit of boring to climb, utilize the frame of placing of taking the small opening to come the filter sieve larva to further filter with the filter screen, can come out fodder and larva effective separation, easy and simple to handle and be difficult for hindering the larva.
2. Through setting up structures such as transfer case, transfer pipe, counter, through moist sand and soil guide mature larva transfer and the pupation of coming into the earth, can also calculate the quantity of larva in the transfer process, be favorable to developing of research experiment.
