Problems solved by technology

In recent years, a lot of research has been done on the southern small flower bug (O.similis), the east Asian small flower bug (O.sauteri), and the tiny flower bug (O.minutus), but the main content is concentrated on biology, taxonomy and molecular biology, etc. aspect, and explored the possibility of its artificial breeding, the current large-scale breeding technology has not yet been reported
Wang Guangpeng et al pointed out in the article "Advances in Artificial Large-scale Breeding of Small Flower Bugs" (Insect Natural Enemies, Volume 27, No. 2, June, 2005) that the feed problem is an important problem in the large-scale breeding of small flower bugs, and it is necessary to find cheap and easy Obtain and feed that is suitable for the growth, development and reproduction of small flower bugs to improve their survival rate and yield; in addition, the egg-laying substrate and adult feed are also an important issue in the large-scale feeding of small flower bugs, which directly affect the oviposition of female adults quantity and hatching rate of eggs, which in turn affect the adult acquisition rate

Embodiment 1

[0030] Embodiment 1 A kind of bait for breeding small flower bugs in East Asia is based on the mixture composed of flour (passing through a 120 mesh sieve): rice=4: 1 (weight ratio), after the mixed base is sterilized and placed in the In a desiccator with supersaturated salt water, balance the relative humidity of about 75% for 7 days, inoculate the base material with acaroid mites, the inoculation amount of acaroid mites is 25-50 heads per gram of base material, after inoculation with acaroid mites, dry Place the device in a constant temperature box at 25±2°C for 20 days. When the amount of acaroid mites in the base material reaches 500-1000 per gram of base material, it becomes the bait for feeding the East Asian flower bug.

[0031] A group breeding method of East Asian stinkbugs, the steps include egg hatching, nymph rearing, transfer of last instar nymphs or adults, the breeding environment conditions are: temperature 25±2°C, relative humidity 75%, adult light cycle 14L:1...

Embodiment 2

[0033] Example 2 A kind of bait for raising stink bugs in East Asia, inoculating acaroid mites on a mixed base material composed of wheat bran, yeast and water at a weight ratio of 9:1:1, and then placing the inoculated base material in a relative humidity Under the environmental conditions of 75% and temperature of 25±1°C, the acaroid mites reproduce. After 18 days, when the amount of acarid mites in the base material reaches 500-1000 per gram of base material, it becomes the bait for feeding the East Asian flower bug.

[0034] A group breeding method of East Asian stinkbugs. The steps include egg hatching, nymph rearing, and transfer of last-instar nymphs or adults. The breeding environment conditions are: temperature 25±1°C, relative humidity 70%, and adult photoperiod 16L:8D. In the nymph feeding stage, take the bait containing acaroid mites and put it in a fresh-keeping box to feed the nymphs of the nymphs for 11 to 13 days. During the whole nymph stage, the supply of feed...

Embodiment 3

[0035]Embodiment 3 A kind of bait for breeding small flower bugs in East Asia is based on the mixture composed of flour (passing through a 100 mesh sieve): rice=5: 1 (weight ratio), and the mixed base is sterilized and placed in the opposite After 8 days of equilibrium under environmental conditions with a humidity of 75%, inoculate acaroid mites on the base material. The inoculation amount of acaroid mites is 30 to 50 heads per gram of base material. Cultivate in the box for 15 days, and when the amount of acaroid mites in the base material reaches 500-800 per gram of base material, it becomes the bait for feeding the East Asian flower bug.

[0036] A group breeding method of East Asian stinkbugs, the steps of which include egg hatching, nymph rearing, and transfer of last-instar nymphs or adults. The breeding environment conditions are: temperature 19±1°C, relative humidity 60%, and adult photoperiod 12L:12D. In the nymph feeding stage, take the bait containing acaroid mites...

Abstract

The invention relates to a feeding bait and process for colonially feeding Orius sauteries, the bait is made through a mode that flour mites are inoculated on a vegetal mixed base and is cultured and propagated, the environmental conditions of the inoculation, the cultivation and the propagation are that the relative humidity is 65-75 percent, the temperature is 24-26 DEG C, and the bait is cultured under the above environmental conditions for 15-25 days. The feeding method comprises hatch, the raising of nymphs, and the transfer of last instar nymphs or imagoes, the environmental conditions of feeding are that the temperature is 17.5-27.5 DEG C, the relative humidity is 60-90 percent, the photoperiodicity of the nymphs is 14-16 Liter : 10-8 days, during the stage of feeding the nymphs, the Orius sauteries are fed for 9-20 days by using the bait, and the quantity supplied of the bait of each Orius sauteri is 0.2-0.5 gram. Using the invention to cultivate the sauteries, the period of the growing development is short, the livability is high, the operation is simple, the practicability is strong, and the production cost is low. The spread and exploitation of the invention is beneficial to the non-polluted prevention of pests and the food safety.

Description

technical field [0001] The invention relates to a feeding bait and a feeding method for insects, in particular to a feeding bait and a group feeding method for East Asian small flower bugs (O. sauteri). Background technique [0002] Orius spp. has a wide range of feeding habits and can prey on some small insects such as thrips, aphids, mites, and whiteflies, as well as eggs and small larvae of Lepidoptera such as cotton bollworms and Spodoptera litura. Because of its wide distribution range, strong adaptability, large number, and strong predatory characteristics, it is considered to be a class of natural enemy insects with great utilization value. [0003] Due to the over-reliance and irrational use of chemical pesticides in recent years, some pests such as thrips, aphids, mites and whitefly have exploded and are difficult to control. The small flower stink just happens to have a good control effect on these small insects. In the 1980s, Canada introduced the American small ...
