Artificial propagation method and apparatus of egg parasitoids

Abstract

The invention discloses an artificial breeding method of egg parasitic wasps and a device thereof. The invention aims at providing an artificial breeding method of the egg parasitic wasps, and mainly aims at providing a new artificial oviposition and breeding method of wasps in a net cage provided with a plurality of layers of grid egg-hanging cards, and providing a device needed by the method. The new artificial oviposition and breeding method is carried out in the net cage provided with a plurality of layers of grid egg-hanging cards, and comprises the following steps: first, a grid hung with the egg card is put on the upper layer of the net cage; after the egg parasitic wasps parasitize, when the egg card is replaced, the grid hung with the egg card is successively moved to the next layer in sequence and in bulk, and then the new grid hung with the egg card is put on the top layer; the egg parasitic wasps are automatically transferred to the new egg card; after oviposition, each layer of the grid egg-hanging card is sequentially moved down to one layer and the new grid egg-hanging card is put on the top layer; finally, the egg cards are removed from the net cage in bulk. The new artificial oviposition and breeding method has the advantages of avoiding the procedures of artificial slapping or sweeping, avoiding the damage to mother wasps in the procedure, and realizing the replacement of the egg card without damaging the mother wasps.

Description

Technical field: [0001] The invention belongs to biological technology, and relates to an artificial propagation method of egg parasitoids and a device required for applying the method. Background technique: [0002] Egg parasitoids are important natural enemy insects for the biological control of agricultural and forestry pests. They lay their eggs in the eggs of parasitic insects, and the larvae feed on the nutrients in the parasitic eggs, thereby achieving the purpose of eliminating natural enemy insects. Ovum parasitoids can distinguish between hosts that have been parasitized and healthy hosts, and avoid over-parasitism or multi-parasitism. Therefore, the same species of oviparasitoids generally do not lay eggs again in parasitized eggs. The flat-bellied wasp is a natural enemy insect for the biological control of litter bugs and pine caterpillars, and it often breeds this bee from November to March of the next year. During this period, due to the low temperature in So...

Problems solved by technology

The flat-bellied wasp has a long egg-laying period and can continuously lay eggs for more than 10 days. When breeding this bee, the host egg card needs to be replaced every day or every other day to make full use of the reproductive efficiency of the adult bee. Because the flat-bellied wasp is parasitizing or looking for host eggs During the process, it has a strong chemotaxis to the host eggs, and is often tightly attached to the egg card and is not easy to separate. When the egg card is replaced, it is easy to damage the adult bees and affect the life of the adult bees and reduce the efficiency of breeding bees.

Glass bottles (tubes) or plastic bottles (tubes, boxes) have low breeding efficiency and fail to meet the needs of large-scale applications; the two methods used by a large number of bees cannot solve the problem of flat-bellied bees escaping from light and beating. Egg stuck causes damage to adult bees and causes waste of breeding bees
