Method for indoor propagation of Bactrocera dorsalis

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...

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 females to lay eggs, and then rinse with water or use a knife or brush to remove the eggs from the ovipositor or ovipositor. Wash down or scrape the eggs to collect the eggs, and then inoculate the collected eggs on the fruit or feed for feeding. During the collection of eggs, it is easy to lose the eggs and cause certain mechanical damage to the eggs. It reduces the hatching rate of eggs and is not conducive to the large-scale reproduction of Bactrocera dorsalis
