Technical Field

The utility model discloses a device is raised to beans hornworm larva.

Background

A Clanis bilineata Walker belongs to Clanis bilineata of Clariaceae of Lepidoptera of Insecta, is a holomorphic insect, and has a whole life cycle including 4 insect states such as egg, larva, pupa and imago, wherein the larva has 5 instars, and 5 instars of mature larva enter the soil for overwintering. The bean hawkmoth is mainly distributed in Huang-Huai river basin, Changjiang river basin and south China, the main host plants comprise soybean, mung bean, cowpea, locust and the like, and because the larva has rich nutritive value and unique flavor, the larva is called as 'Clanis bilineata' and has extremely high protein content. The bean hawk moth is used for eating in many areas of China, and is famous for producing and eating the bean hawk moth, especially in Shuyun county in Jiangsu province. "Shuyun Doudan" has become famous snack and local business card in this area, it is the necessary delicious food for local people to ask for visitors. With the increase of market demand, the quantity of the larvae naturally generated in the field is far from meeting the demand of people.

Currently, clanis bilineata tsingtauica can only be raised by planting soybeans. Generally, 12000-15000 eggs are needed to be inoculated to each mu of soybean, and only 80-100 jin of clanis bilineata tsingtauica can be harvested after 30-40 days. Moreover, under natural conditions in the field, the soybean pod moth larvae are also parasitized and preyed by parasitoid bees, parasitic flies, mantises, spiders, frogs, birds and the like, and the parasitization and the preying of the natural enemies to the soybean pod moth larvae can cause the yield reduction of the soybean pods by about 5 to 10 percent. More importantly: the parasitic and predation probability of the 1-3 instar larvae is higher than that of the 4-5 instar larvae. Therefore, the larvae of 1-3 ages are bred to 3-4 ages in an indoor large-scale mode and then are released to the field, the field breeding time can be obviously shortened, the loss in the field breeding process is reduced, the marketing time of the clanis bilineata tsingtauica is advanced by 30-50 days, and the sale price and the economic benefit are obviously improved.
