High yield breeding method of bean hawk moth

Abstract

The invention discloses a high-yield greenish brown hawk moth breeding method, which belongs to the technical field of insect breeding and solves the problems of short supply cycle, low per mu yield and low economic benefit of greenish brown hawk moth breeding in the prior art. The high-yield greenish brown hawk moth breeding method comprises the following steps: (1) choosing the greenish brown hawk moth species; (2) establishing a breeding field; (3) managing the breeding field: a greenhouse in the breeding field is divided into three blocks; the first block is used for growing soybeans in the middle ten days of March, the second block is used for growing the soybeans in the middle ten days of April, and the third block is used for growing the soybeans in the first ten days of June; (4) establishing a breeding field; (5) rotation of the soybeans in the breeding field: the breeding field is divided into blocks, the soybeans are planted in batches next year, and the soybean planting way is the same as the management mode of the breeding field; (6) breeding female moths: from the last ten days of April, the greenish brown hawk moth adults fly out successively, and after mating, the female moths are caught and put in the breeding field; (7) catching the greenish brown hawk moth: from the first ten days of May to early October, the greenish brown hawk moths at the right age are caught at regular intervals.

Description

technical field [0001] The invention relates to the technical field of insect breeding, in particular to a method for high-yield breeding of bean dan. Background technique [0002] Bean Dan, also known as bean worm, is the larva of bean hornworm (Clanis Bilineata Walker). Bean hornworm, belonging to Lepidoptera, Sphedidae, is distributed in Hebei, Henan, Shandong, Anwei, Jiangsu, Hubei, Sichuan, Shaanxi and other provinces. It is the main pest of soybean crops, and can also harm mung beans, cowpeas, etc. The larvae of this insect feed on soybean leaves and can eat the leaves into notches. When there are many insects, they can eat soybean plants into bare stalks. One larva can eat up 2-3 bean leaves. [0003] The bean hornworm has four life stages including egg, larva, pupa and adult. Due to the rich nutrients in the soybean meal and pupae, many areas in my country have the habit of eating soybean meal. In particular, Guanyun County, Jiangsu Province has a history of eat...

AI Technical Summary

Problems solved by technology

In the past ten years, people have been exploring the methods of artificial breeding of bean dan, but basically they all ended in failure.

The main problems are that the understanding of the life history of bean dandelion is not thorough enough, the selection of stinging bean dandelion species, overwintering preservation, artificial stocking of bean dandelion, natural enemy control and other technologies are not up to standard, etc.

Therefore, the seasonal problem of beans supply has not been resolved
