Problems solved by technology

[0003] In the existing method of raising Bactrocera dorsalis, the first is to place fruit in the insect cage, and the female will lay eggs in the fruit to breed, the fruit is easy to rot and breed bacteria, and the smell is particularly pungent and unpleasant in summer, which is not conducive to Indoor large-scale breeding, and the workload is cumbersome and complicated, requiring a lot of labor; the second is to use an ovipositor or ovipositor for fema...

Embodiment 1

[0023] A method for indoor propagation of Bactrocera dorsalis comprises the following steps:

[0024] (1) Breeding of Bactrocera dorsalis adults: Breed Bactrocera dorsalis adults in insect cages, the breeding temperature is 26±1°C, the humidity is 60-70%, the photoperiod is L:D 12:12; the size is 50cm *50cm*50cm insect cages can have a stocking density of up to 5,000 animals / cage. The insect cages provide adult feed and water. The adult feed consists of 20 parts of yeast powder, 16 parts of tryptone, 70 parts of sucrose, and 3 parts of vitamin C. 15 parts of water; protein is an essential nutrient source in the growth process of Bactrocera dorsalis, especially for the development of the reproductive system. Adding protein in the adult feed is beneficial to the development and growth of Bactrocera dorsalis, improving the oviposition rate and Egg hatching rate, etc.;

[0025] (2) Acquisition of Bactrocera dorsalis ovum: Bactrocera dorsalis 8 days old in summer or 15 days old in...

[0036] A method for indoor propagation of Bactrocera dorsalis comprises the following steps:

[0037] (1) Breeding of Bactrocera dorsalis adults: Breed Bactrocera dorsalis adults in insect cages, the breeding temperature is 26±1°C, the humidity is 60-70%, the photoperiod is L:D 12:12; the size is 50cm *50cm*50cm insect cages can have a stocking density of up to 5,000 animals / cage. The insect cages provide adult feed and water. The adult feed consists of 25 parts of yeast powder, 12 parts of tryptone, 65 parts of sucrose, and 3 parts of vitamin C. 20 parts of water;

[0038] (2) Acquisition of Bactrocera dorsalis eggs: Adults of Bactrocera dorsalis are 8 days old in summer or 15 days old in winter, and they are placed in a feeding tray with a culture medium in the insect cage. A number of small holes, the thickness of the medium is 3cm, the diameter of the small holes is 1mm, the depth of the holes is 10mm, and the hole spacing is 5mm to provide Bactrocera dorsalis adults to l...

Abstract

The invention relates to the technical field of insect rearing, and specifically discloses a method for indoor propagation of Bactrocera dorsalis. The method comprises the following steps: Bactroceradorsalis adult rearing; acquisition of Bactrocera dorsalis eggs, namely 8-day-old in summer or 15-day-old in winter Bactrocera dorsalis adults are used, and a culture medium is used as a Bactrocera dorsalis spawning site; Bactrocera dorsalis larva rearing, namely the eggs hatch into larvae in the culture medium, and the larvae feed on the culture medium; and collection of pupa. The method of the invention is used for large-scale propagation of Bactrocera dorsalis, is not restricted by seasons, can rapidly cultivate a large number of Bactrocera dorsalis, and provides experimental materials forthe research on biology, physiology and integrated pest prevention and treatment measures of Bactrocera dorsalis. In the method, the culture medium is used as the spawning site of Bactrocera dorsalisand an egg hatching site, and at the same time, the culture medium is also the feed for larvae, so that an egg collection step is avoided, the mechanical damage to the eggs is reduced, a hatching rateof the eggs is improved, and thereby the purpose of propagation is achieved.

Description

technical field [0001] The invention belongs to the technical field of insect breeding, in particular to a method for indoor propagation of Bactrocera dorsalis. Background technique [0002] Bactrocera dorsalis, commonly known as fruit maggot, belongs to Diptera, Tephritidae, Oligochaetes subfamily, and Oligochaetes genus. Bactrocera dorsalis is a worldwide quarantine pest that can eat and harm more than 300 kinds of cultivated fruit and vegetable crops and wild plants, causing huge harm and economic losses to agricultural production and agricultural product trade. It is an important pest of tropical and subtropical fruits and vegetables. biology. The insect is mainly harmful to the larvae. Adults lay eggs in the fruit, resulting in local softening of the pulp tissue; after hatching, the larvae hide in the fruit pulp to feed on the pulp, often causing the fruit to rot or fall off before it is ripe, seriously affecting the yield and quality of the fruit. Due to the characte...
