Method for reducing mortality rate of low-age nymphs in breeding of orius sauteri

Abstract

The invention relates to the technical field of insect breeding, in particular to a method for reducing the mortality rate of low-age nymphs in breeding of orius sauteri. The method is characterized in that gel and filter paper are matched for moisturizing bean sprouts and replenishing water and honey to orius sauteri, so that water is not required to be added in the breeding process of first-agenymphs and second-age nymphs; meanwhile, the bean sprouts can be kept fresh for a long time (one week or longer), and the bean sprouts can grow into leaves again, so that plant nutrition and moistureare provided for the orius sauteri. Therefore, the breeding method which is low in cost, convenient to operate, suitable for large-scale production and capable of effectively reducing the mortality rate of the low-age nymphs of the orius sauteri can be created according to the biological characteristics and growth and development requirements of the low-age nymphs.

Description

Technical field [0001] The present invention relates to the technical field of insect breeding, in particular to a method for reducing the mortality of young and middle-aged nymphs in the breeding of East Asian nymphs. Background technique [0002] East Asian flower bugs belong to the genus Hemiptera Hemiptera. They are the dominant natural enemy population in northern my country. They can prey on a variety of pests in forests, orchards, greenhouses and farmlands. Both adults and nymphs can prey on aphids, thrips, and leaves. Small arthropods such as mites, as well as eggs and newly hatched larvae of various lepidopteran pests. The insect is highly adaptable, widely distributed, and large in number. It is generally considered to be a kind of predatory natural enemy insects with great usefulness and great potential for biological control. It will have a wide range in the era of food safety and ecological safety. Application prospects. From the end of the 1980s to the present, man...

Problems solved by technology

Among them, when plant tissues such as bean sprouts and beans are used to replenish water for young nymphs, these plant tissues can maintain water for a long time in a small space (glass test tube, petri dish, etc.), and can increase the humidity for a small space, which is beneficial to The growth and life maintenance of young nymphs, but large-scale feeding requires a larger feeding device. When plant tissues such as bean sprouts and beans are used, it is easy to lose water, and the young nymphs have weak stabbing ability, which makes them unable to suck water in plant tissues. Death; when using absorbent cotton balls for water replenishment, because the young nymphs are small, they will drill into the cotton balls, and individual deaths will occur during feeding. Larger or adding water to the cotton ball will lead to death by drowning. At the same time, the cotton thread in the cotton ball will also entangle the body of the nymph and cannot break free and cause death; Larger, there will be rotting of plant tissues
