Embodiment 1

[0041] [Example 1] Induction of female, male and female cotton aphids under short light conditions at 16°C

[0042] Feeding of cotton aphid parthenogenes: Soak cotton seeds in warm water at 45°C for 35 minutes to accelerate germination, mix nutrient soil and vermiculite at a volume ratio of 1:4 to make a cultivation substrate and transfer them to flowerpots, and place the accelerated Budding cotton seeds are inserted into the above-mentioned cultivation substrate, and watered until the substrate in the flower pot is drenched. When the two cotyledons of the cotton seedlings are fully expanded, the cotton aphids are inoculated on the cotyledons. The feeding conditions of parthenogenetic aphids are photoperiod 16L:8D, temperature 25°C, relative humidity 75%, and the population density of cotton aphids is controlled at 5 heads / cm 2 Below, to avoid the generation of winged aphids.

Embodiment 2

[0045] [Example 2] Induction of female, male and female cotton aphids under short light conditions at 18°C

[0046] Cotton aphid parthenogenetic breeding: Soak cotton seeds in warm water at 50°C for 30 minutes to accelerate germination, mix nutrient soil and vermiculite at a volume ratio of 1:5 to make a cultivation substrate and transfer them to flower pots, and put the accelerated germination Insert the cotton seeds into the above-mentioned cultivation substrate, and water until the substrate in the flower pot is drenched. When the two cotyledons of the cotton seedlings are fully expanded, the cotton aphids are inoculated on the cotyledons. The feeding conditions of parthenogenetic aphids were photoperiod 14L:10D, temperature 25°C and relative humidity 75%. Control the cotton aphid population density at 5 heads / cm 2 Below, to avoid the generation of winged aphids.

Abstract

The invention discloses an indoor high-efficiency induction method for cotton aphid females, males and females, and belongs to the field of agricultural pest control. Under natural conditions, only one generation of female, male, and female cotton aphids occurs each year. The existing induction method takes 3 to 5 generations to induce male and female aphids, but there are always asexual parthenogenetic aphids mixed in, and The steps are cumbersome. Aiming at this technical problem, the present invention firstly provides a method for raising cotton aphid parthenogenetic aphids, and designs a device for inducing sexual aphids of cotton aphid, and transplants cotton seedlings at the cotyledon stage into the device, and inoculates 1-year-old orphan The female nymphs are then kept under low temperature and short light for continuous feeding. The parthenogenetic aphids develop into adults to produce sexual females and male aphids, and when the sexual females develop into adults, they can produce sexual females. The invention is easy to operate, fast and efficient, and can induce batches of neatly developed females, males, and females of cotton aphids in a short period of time, which will promote the research on basic biology of cotton aphids and become a new strategy for the prevention and control of cotton aphids Lay the groundwork for development.

Description

technical field [0001] The invention belongs to the field of agricultural pest control, and in particular relates to an indoor high-efficiency induction method for female, female and male aphids of cotton aphids. Background technique [0002] Cotton aphid (Aphis gossypii), also known as melon aphid, belongs to Hemiptera Aphididae. It harms crops by absorbing plant juice, secreting honeydew, and spreading plant viruses. Its host range covers more than 900 species of plants in 135 families, including grains, vegetables, fruits, and forest trees, causing major economic losses to the world's agricultural and forestry production every year. The occurrence and harm of cotton aphid are closely related to its unique reproductive mode, which has plasticity, and can choose parthenogenesis or sexual reproduction according to seasonal changes. Parthenogenesis can make the population of cotton aphids expand rapidly during the plant growing season, and the damage will be aggravated, whil...
