Method for prolonging storage period of egg masses of noctuid black egg bees

Abstract

The invention discloses a method for prolonging the storage period of egg masses of noctuid black egg bees, which comprises materials and a reaction device, and the materials comprise the following components in parts by weight: 5-10 parts of a thickening agent, 1-3 parts of inorganic salt, 30-40 parts of sodium alginate, 20-30 parts of carrageenan, 5-10 parts of an inorganic antibacterial agent, 40-50 parts of egg white, 3-6 parts of quick lime, 2-4 parts of a preservative and 1-3 parts of cellulase. 30-40 parts of sodium alginate, 20-30 parts of carrageenan and 40-50 parts of egg white are contained in the reaction device, and the reaction device is a main outer frame mounting structure of the equipment. According to the method for prolonging the storage period of the egg masses of the noctuid black egg bees, the formed raw materials are semi-solid materials, the egg masses are placed in the semi-solid materials, the semi-solid materials have good cold absorption performance and can keep the internal low-temperature state in a matched mode, the incubation time of the egg masses is prolonged, the raw materials contain operating substances, and the success rate of eclosion of the egg masses is increased.

Description

technical field [0001] The invention relates to the technical field of insect breeding, in particular to a method for prolonging the storage period of egg masses of the noctuid moth. Background technique [0002] The wasp is an important parasitic natural enemy in the egg stage of a variety of Lepidoptera Noctuidae insects. Because the wasp has high parasitic performance and is easy to reproduce in large numbers, it makes It has become one of the main biological factors in the control of Lepidoptera Noctuidae pests. As early as the 1980s, Venezuela had multiplied Noctuid moth and used it to prevent and control Spodoptera frugiperda. Among them, in areas with high humidity, in corn fields The highest parasitism rate of eggs can reach 90%. In Mexico, in the corn-soybean, corn-pumpkin, corn-soybean-pumpkin and single corn planting areas, through the quantitative release of Noctua spp. The parasitism rate of moth eggs shows that it is found that the parasitism rate and the rele...
