Method for preserving larvae of oriental fruit moths

Abstract

The invention discloses a method for preserving the larvae of oriental fruit moths, which includes the steps of feed preparation, inoculation, feeding conditions, collecting old mature larvae, preserving the larvae, pupation and eclosion and the like. With the adoption of the method, the preserving period can be prolonged to 6 months, which is 12 times of the preserving period in the prior art; the average oviposition of single female adult is 100, which is 2.5 times of that in the prior art. The adult has no deformity, and the average life is 9.4 days, which is more than 2 times of the life in the prior art. With the adoption of the preserving method, after the popation of the old mature larvae, the eclosion and the oviposition of the adults, the diameter of the egg is 75 micrometers, thehatching rate is more than 87%, and the larva development period is 13 days, and the larvae are not significantly different from those of the normal feeding. By adopting the method, the space can besaved, the 100 insects can be saved in one liter of space, and the preserving cost is reduced by more than 70% compared with the prior preserving method. By adopting the method, a sufficient amount oftest insects can be normally provided in winter and spring seasons when the oriental fruit moths are difficult to raise, and the test is carried out normally.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to a method for prolonging the storage period of the small pear borer worm. Background technique [0002] Pear borer is a kind of fruit-boring pest, which occurs and harms in a large area in my country. In order to study the behavior, physiology and control technology of the small pear borer, it is necessary to carry out long-term breeding and preservation indoors. During the breeding process, the small pear borer has been in the growth and development stage, which is quite different from the actual living conditions in nature. After long-term subculture, population degradation and other problems will occur. At the same time, in order to achieve the purpose of long-term preservation of indoor populations, it is necessary to continue to raise them, and the above work needs to consume a lot of manpower and material resources. At present, the common method of pre...

Problems solved by technology

Problems existing in the prior art Solve the problem that the storage period of the small pear borer is too short by preserving the pupae, which has little effect on alleviating the decline in quality and quantity of
