Method for delaying eclosion of aedes albopictus pupas and method for transporting aedes albopictus pupas

Abstract

The invention relates to a method for delaying eclosion of aedes albopictus pupas and a method for transporting aedes albopictus pupas. The method for delaying eclosion of aedes albopictus pupas comprises the following step: preserving aedes albopictus pupas in an environment of 16-21 DEG C. Tests show that if the aedes albopictus pupas are preserved at 16-21 DEG C, the time from nymphosis to eclosion is prolonged, normal eclosion can be still achieved for the preserved aedes albopictus pupas, and the aedes albopictus pupas and the number of dead mature misquotes after eclosion are not greatlydifferent from those of room-temperature eclosion. In the transportation process of the aedes albopictus pupas, the temperature of the transportation environment is kept within 16-21 DEG C, then theaedes albopictus pupas can be prevented from eclosion in the transportation process, remote-distance transportation of the aedes albopictus pupas can be achieved, the transportation space can be greatly saved, the transportation cost can be reduced, and large-scale transportation of factories is powerfully ensured.

Description

technical field [0001] The invention relates to the technical field of mosquito control, in particular to a method for delaying the emergence of Aedes albopictus pupae and a method for transporting Aedes albopictus pupae. Background technique [0002] Artificial rearing of insects is one of the basic techniques for studying entomology. It can breed certain types of insects regardless of the season for research on insect biology, physiology and the formulation of integrated pest control measures. Mosquito, It belongs to the Diptera Mosquito family of Insecta, and there are about 3,000 species in the world. It is a tiny flying insect with sucking mouthparts. Usually female mosquitoes feed on blood, while males feed on plant sap. Blood-sucking female mosquitoes are intermediate hosts for dengue, malaria, yellow fever, filariasis, Japanese encephalitis, and other pathogens. [0003] At present, with the continuous deepening of mosquito ecology and control technology research,...

Problems solved by technology

[0003] At present, with the continuous deepening of research on mosquito ecology and control technology, especially the in-depth development of wolbachia technology, the release of male mosquitoes carrying wolbachia, that is, "mosquito control with mosquitoes", has become the most cutting-edge control method at present. Therefore, in the experiment When the target male mosquitoes can be mass-produced in laboratories and workshops, a reasonable transportation and release method is an important factor for the smooth implementation of "killing mosquitoes with mosquitoes". However, there are few research reports on the transportation and release of male mosquitoes and pupae at home and abroad.

[0004] The male pupae of Aedes albopictus begins to emerge about 45 hours after pupae, but the separation time of male and female is generally 35-40 hours after pupae, and the time to eclosion is very short, so the long-distance transportation of Aedes albopictus pupae cannot be realized

Therefore, the existing transportation and release methods are to transport adult mosquitoes and release adult mosquitoes. The problem with this method is that a small space will cause a large number of adult mosquitoes to die after emergence, so a large space is required for storage and transportation volume, resulting in high transportation costs. , it is difficult to popularize and apply in the case of large-scale release
