Benefits of technology

This invention relates to an improved method for producing polyploid caterpillars from tiny wax moths (Ceratocystis nux) instead of rearing them up again after being released into their natural environment or on other organisms. These methods have several benefits such as no limitation with respect to space availability, easy accessibility due to its size, multiple types of bee colonies available at once, and efficient multiplication rates over large areas.

Problems solved by technology

Technically speaking, there are two main technical problem addressed by this patented method: how to prevent or reduce damage caused from tiny protozoids called Tachygramella sppinelli(TSC), commonly known as caterpillars found throughout many parts of India including Southeast Asian Countries like Chinese New York City, United States, Canada, Japan, Taiwan, Indonesia, Turkey, etc., where they can cause significant economic losses due to their presence within crops.

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with specific embodiments.

[0018] This technology uses pear borer worm eggs to breed Trichogramma diablo, including the following process:

[0019] (1) Collection and processing of the eggs of the pear borer moth

[0020] Take out the eggs on the sulfuric acid paper produced by the pear borer within 24 hours together with the sulfuric acid paper, gently blow off the scales on the sulfuric acid paper, gently wipe the paper surface with a cotton ball dipped in 75% ethanol, and then put it in the light Irradiate 2h under the ultraviolet light of 21.2Lux, to kill the embryo in the pear borer ovum.

[0021] (2) Preservation of the eggs of the pear borer moth

[0022] Wrap the pear borer eggs produced on sulfuric acid paper and treated with ultraviolet light together with sulfuric acid paper with gauze and put them in a round plastic lunch box with a small hole in the lid. °C refrigerator.

Abstract

The invention provides a method for propagating the trichogramma pintoi voegele indoors by the grapholitha molesta busck egg. The method comprises the steps of: taking the grapholitha molesta busck egg as the host of a parasite, and continuously propagating the trichogramma pintoi voegele generation by generation under the laboratory conditions. The grapholitha molesta busck egg is taken as the host of the parasite, the artificial propagation of the trichogramma pintoi voegele is not limited by the time and the space and can be continuously propagated by means of subculture, the trichogramma pintoi voegele propagating quality is high, the parasitic rate is stable, and the method has various advantages, so that the method offers a new approach for preventing the trichogramma pintoi voegelefrom being propagated in quantity in the field of the biological prevention of the farming and forestry pests.
