Problems solved by technology

However, the bee source produced by this method is difficult to preserve for a long time, and it is necessary to continuously carry out additional generation breeding according to the plan, and it is necessary to accurately grasp the breeding process of each generation and accurately predict the period and amount of occurrence of target pests
During the breeding process, if there is a problem in any intermediate link, it will seriously affect the original plan and the yield and quality of the bee source. In pest control, it is difficult to match the occurrence period of parasitic bees and pests (bees and insects), and it is easy to miss The best period for pest control, affecting the control effect or causing waste
my country has made some new progress in the artificial reproduction and utilization of Trichogramma and Trichogramma, such as the first use of artificial host eggs to replace natural host eggs in the breeding of Trichogramma; ) has developed a cotton bollworm production line. Although these methods have made some major improvements in some important links, they still have not gotten rid of the traditional artificial succession (addition) generation breeding mode and solved the problem of bee insect counterparts.

Embodiment approach

[0007] 1. Feeding of host armyworm:

[0008] At a temperature of 20-25°C, the late 1st instar and early 2nd instar larvae grow into 3rd instar larvae, and then feed the 3rd instar larvae with artificial feed to turn into pupae, and the pupae emerge into adults, and then the adults produce armyworm eggs, and the armyworm eggs become Newly hatched larvae, newly hatched larvae grow into late 1st and 2nd instar larvae; in order to adjust the production progress during this process, armyworm pupae can be stored at 10-15°C for a storage time of ≤30 days, and armyworm eggs can be stored in Store at 5-10°C, storage time ≤ 30 days.

[0009] 2. Breeding of bee species:

[0010] Inoculate artificially bred uniform 1-2 instar armyworm larvae into the inoculation box, and inoculate the mid-red wasp species that emerged from the developing green cocoon at a ratio of 1:20. The ratio of male to female Match 1:1. Take a small number of parasitized larvae from the produced parasitized larvae...

Embodiment 1

[0025] Embodiment 1 The artificial breeding method of the red parasitic wasp 1, the raising of the host armyworm:

[0026] At 25°C, the late 1st instar and early 2nd instar larvae grow into 3rd instar larvae, and then feed the 3rd instar larvae with artificial feed to become pupae, pupae emerge into adults, and then adults produce armyworm eggs, which become newly hatched Larvae, newly hatched larvae grow into late 1st and 2nd instar larvae.

[0027] 2. Breeding of bee species:

[0028] Insert 1,000 artificially bred uniform 1-2 instar armyworm larvae into the inoculation box, and insert 100 species of B. chinensis that emerged from the developing green cocoon at a ratio of 1:20. head, the ratio of male to female is 1:1. Take 100 parasitized larvae among the generated parasitized larvae, raise them to cocoons at 25° C. under a 12-hour photoperiod for 8 days, and then stimulate cocoons at 25° C. to produce bee species.

[0029] 3. Breeding of diapause bee sources:...

Abstract

An artificial reproduction method for Microplitis mediator (Haliday) with sexual dispause performance as natural enemy of pests features that the armyworm is used as intermediate host and said Microplitis mediator can be induced to form diapause source in artificial condition for storage for a long time, and the dispause may be released for application at all times according to the occurring time and quantity of harmful insects.

Description

Technical field: [0001] The invention relates to the technical field of biological control of crop pests, in particular to an artificial breeding method of natural enemy insects. Background technique: [0002] The artificial breeding and release of natural enemy insects are important technical measures for pest biological control, among which the artificial breeding and utilization of parasitic natural enemies occupy a very important position. There are many available natural enemy insect resources in the world, especially in my country. Because there are no suitable alternative hosts and corresponding scientific breeding methods and methods, only a very small number of natural enemy insects can be artificially propagated and utilized at home and abroad. At present, what is usually used at home and abroad is a traditional method of artificial step (addition) generation breeding. This method is to use some kind of alternative host (intermediate host) that can parasitize the p...
