Amplification technology for amblyseius eharai amitai et swirski domestication population and application thereof

Abstract

The invention relates to an amplification technology for an amblyseius eharai amitai et swirski domestication population. The technology is implemented by the following specific steps: feeding carpoglyphus lactis with a mixture of yeast and vitamin E as a compound food; feeding amblyseius eharai amitai et swirski with the carpoglyphus lactis fed in the last step as a substitute food forcibly; screening individuals which develop normally after taking the substitute food, lay a large number of eggs and are long in service lives from a natural population of amblyseius eharai amitai et swirski in multiple generations; raising the screened individuals in a centralized way to obtain a primary domestication population; performing tetranychidae feeding habit on the primary domestication population to obtain individuals having strong predation on carpoglyphus lactis and tetranychidae; raising the screened individuals in a centralized way to obtain a final domestication population; amplifying the final domestication population by taking the carpoglyphus lactis fed with the compound food of yeast and vitamin E as a substitute food on the basis.

Description

technical field [0001] The invention relates to the amplification technology and application of the domesticated population of A. japonicus mite. Background technique [0002] Amblyseius japonicus ( Amblyseius eharai Amitai & Swirski) are predatory mites (natural enemies), mainly distributed in citrus, tea, loquat, longan and other orchards in my country and other plants in nature, and use harmful mites or pests on these plants as food (prey). In 1995, some people used different plant pollen (natural food) to raise A. japonicus, and thought that canna pollen was more suitable for indoor rearing of A. japonicus, but no systematic reproductive effect measurement was carried out. But above-mentioned pollen needs to plant a large amount of plants in advance and just can obtain, and to obtain insect also needs to plant a large amount of plants as the food of insect, but the production of plant has seasonality, thus can not supply pollen or insect at any time, if want to obtain a...

Problems solved by technology

But above-mentioned pollen needs to plant a large amount of plants in advance and just can obtain, and to obtain insect also needs to plant a large amount of plants as the food of insect, but the production of plant has seasonality, thus can not supply pollen or insect at any time, if want to obtain a large amount of plants at any time , can only be planted in greenhouses (the construction and use costs of greenhouses are relatively high, and a large amount of manual management and pollen collection are required, and the operability is not strong). In addition, pollen and insects are not easy to store for a long time, so pollen and insects are used Insects are the food of A. japonicus, and the cost of amplifying the population of A. japonicus is relatively high. However, due to cost issues, A. japonicus has not been developed and applied on a large scale.
