Abstract

The invention discloses a method for adjusting the diapause of Exorista civilis Rond. The method comprises the following steps that (1) the Exorista civilis Rond with the diapause to be induced is placed in the environment with the conditions that the temperature is 17+ / -1DEG C, and the photoperiod ranges from L8:D16 to L12:D12, and induction is carried out on the Exorista civilis Rond so that the Exorista civilis Rond can be in a diapause state; (2) the Exorista civilis Rond which is obtained in the step (1), and is in the diapause state is stored in the dark with the temperature of 4DEG C; (3) after storage in the step (2) is accomplished, the Exorista civilis Rond is placed in the environment with the conditions that the temperature is 23+ / -1DEG C, and the photoperiod ranges from L14:D10 to L16:D8, and development is recovered. According to the method for adjusting the diapause of the Exorista civilis Rond, the diapause induction rate is 100%, the storage period after the diapause can be 120 days, and eclosion adult Exorista civilis Rond can be obtained after 20 days when the diapause is removed. The method for adjusting the diapause of the Exorista civilis Rond has important significance for large-scale expanding propagation of the Exorista civilis Rond, extension of the shelf life of Exorista civilis Rond products and the field prevention and control action time of the Exorista civilis Rond products, improvement of pest control efficiency, deepening of understanding about the natural enemy insect development mechanism, and exploration of the adaptive mechanism of insects to the environment and the evolution path of the insects.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and relates to a method for regulating the diapause of parasitoid flies. Background technique

[0002] Natural enemy insects are insects that parasitize or prey on other insects, and they control the development and spread of pests in farmland, forest areas and pastures. The resources of natural enemy insects in our country are very rich and have a strong material basis for development and application. By developing the large-scale production technology of natural enemy insects, adopting the method of large-scale breeding of natural enemy insects indoors and the technology of large-scale release, the initial population of natural enemies in the field can be increased, combined with biological pesticides and ecological technologies, a relatively complete technical system of pest control can be formed to replace or reduce The frequency and dosage of chemical pesticides are used to protect the environm...
