Problems solved by technology

The former involves a three-level nutritional relationship. There is a certain proportional relationship between the number of herbivorous insects and predatory stinkbugs, and herbivorous insects generally have to develop to a certain age before they can feed predatory stinkbugs. Increase the cost of feeding, and the food intake of predatory bugs at different ages is not the same. In the actual breeding process, there will often be a shortage or excess of living herbivorous insects, which will cause insufficient food for predatory bugs, slow population growth, or It is the waste of resources caused by the surplus of food
It is simple and convenient to directly raise predatory stinkbugs with artificial feed, but there are not many successful cases of raising predatory stinkbugs with artificial feed alone for large-scale production in my country. The phenomenon of high mortality and population degradation, currently there is no artificial feed suitable for most predatory stinkbugs, and the utilization rate of artificial feed is low, the cost of raw materials is high, it is easy to deteriorate, and the packaging process is complicated

Embodiment 1

[0033] Raise armyworms with artificial feed. When armyworm larvae reach the 5th instar, pick them out, wash them with tap water to remove feces and food residues, and put them in a water bath with hot water at 60°C for 8 minutes to prevent late insects Blackened, when soaked, turn it 2-3 times, then take it out and spread it out on absorbent paper to dry quickly, collect it in a plastic box, and store it in a -20°C refrigerator. When in use, take out the required amount, and after thawing at room temperature, put it into the feeder. The feeding conditions are as follows: the temperature is 25±1° C., the humidity is 65±5%, and the photoperiod L:D=14h:10h.

Embodiment 2

[0035] Raise armyworms with artificial feed. When armyworm larvae reach the second instar, pick them out, wash them with tap water to remove feces and food residues, and soak them in a water bath with 40°C hot water for 10 minutes to prevent late insects When blackened, turn it over 2-3 times when soaking, then take it out and spread it out on absorbent paper to dry quickly, collect it in a plastic box, and store it in a -10°C refrigerator. When in use, take out the required amount, and after thawing at room temperature, put it in for feeding. The feeding conditions are as follows: the temperature is 25±1° C., the humidity is 65±5%, and the photoperiod L:D=14h:10h.

Embodiment 3

[0037] Raise armyworms with artificial feed. When armyworm larvae reach the third instar, pick them out, wash them with tap water to remove feces and food residues, and soak them in a water bath with 70°C hot water for 5 minutes to prevent late insects Blackened, when soaked, turn it 2-3 times, then take it out and spread it out on absorbent paper to dry quickly, collect it in a plastic box, and store it in a -80°C refrigerator. When in use, take out the required amount, and after thawing at room temperature, put it in for feeding. The feeding conditions are as follows: the temperature is 25±1° C., the humidity is 65±5%, and the photoperiod L:D=14h:10h.

Abstract

The invention relates to a method for artificially feeding predatory bugs by preys in freezing storage. The method includes the steps: storing phytophagous insects in a freezing manner; unfreezing the phytophagous insects stored in a freezing manner and then feeding the predatory bugs. The phytophagous insects of the right age are stored for a long time by a deep freezing method and used for feeding the predatory bugs, or the frozen phytophagous insects are taken out to supplement short supply of phytophagous insect living bodies, continuous food supply for the predatory bugs is ensured, scale reproduction of the predatory bugs is guaranteed, and cost is saved.

Description

technical field [0001] The invention belongs to the breeding field of predatory stinkbugs, in particular to a method for artificially raising predatory stinkbugs with frozen stored prey. Background technique [0002] Predatory stinkbugs are omnivorous or carnivorous natural enemy insects, which can prey on a variety of pests that endanger agriculture and forestry, such as Lepidoptera larvae, Coleoptera larvae and adults, aphids, leafhoppers, and thrips. Therefore, many species of predatory stinkbugs are important natural enemies of agricultural and forestry pests, and are used for biological control, which meets the development requirements of green agriculture and has great economic value and ecological benefits. my country is rich in resources of predatory stinkbugs, and has great potential for development, such as stinkbugs, beneficial stinkbugs, hunting stinkbugs, red-colored stinkbugs, Lygus japonica, and East Asian small stinkbugs, etc., which have been used to control...
