Open feeding technique of Amblyseius barkeri

Abstract

The invention discloses an open feeding technique of Amblyseius barkeri, which comprises the following steps of: 1. putting wheat bran in a closed space, sterilizing the wheat bran, taking out the wheat bran and storing the wheat bran for future use; 2. humidifying the sterilized wheat bran, containing the wheat bran in a culture cup, inoculating flour mite stocks in the culture cup for culture and obtaining feed flour mites; 3. putting Amblyseius barkeri stocks and the feed flour mites in the culture cup for culture, and obtaining stocks for open packaging bag feeding and propagation expansion; and 4. taking sterilized and humidified wheat bran, the Amblyseius barkeri stocks cultured in the step 3 and the feed flour mites cultured in the step 2, and evenly mixing the Amblyseius barkeri stocks and the feed flour mites for packaging bag feeding to obtain products which can be delivered for use. The open feeding technique of Amblyseius barkeri has the advantages that the large-scale production can be formed rapidly, the infection of other mites can be more effectively prevented, and the factory production capacity and the pest mite control effect through field application of the Amblyseius barkeri are further improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an open breeding technique for the predatory mite Amblyseius pasteurii, a natural enemy of harmful mites. Background technique [0002] In my country, many kinds of agricultural and forestry crops have long suffered from the rampant damage of harmful mites (including spider mites, rust ticks, thrips, and tarsal mites). In my country's citrus producing areas, spider mites and rust ticks are the most important pests. The number of times chemical pesticides are used for prevention and control each year is more than 20, accounting for about 60%-70% of the total amount of pesticides used in the year, which seriously affects the output and quality of citrus. At the same time, red spiders and other mites are the main pests, as well as fruit trees such as apples, pears, peaches, chestnuts, dates, coconuts; guava, custard apple, papaya, strawberries and other fruits; melons, eggplants, beans...

AI Technical Summary

Problems solved by technology

At present, it is known that the artificial hatching and breeding method of predatory mites in China is prone to infection and the production cycle is long, so it cannot achieve large-scale rapid production

It is simply unable to meet the market demand for large-scale promotion and application in the country
