Embodiment 1

[0041] [Example 1] Induction of females, males and females of cotton aphid under 16℃ short light conditions

[0042] Breeding of cotton aphid and parthenogenetic aphid: Put cotton seeds in warm water at 45℃ for 35 minutes to accelerate germination, mix nutrient soil and vermiculite in a volume ratio of 1:4 to form a cultivation substrate and transfer it to flower pots. The budding cotton seeds are inserted into the above-mentioned cultivation substrate, and watered until the substrate in the flowerpot is soaked. When the two cotyledons of the cotton seedling are fully expanded, the cotyledons are inoculated with cotton aphid. The breeding conditions of parthenogenetic aphid are 16L:8D photoperiod, temperature 25℃, relative humidity 75%, and the population density of cotton aphid is controlled at 5 heads / cm 2 Below, to avoid the production of winged aphids.

Embodiment 2

[0045] [Example 2] Induction of females, males and females of cotton aphid under 18℃ short light conditions

[0046] Breeding of parthenogenetic aphid of cotton aphid: soak cotton seeds in warm water at 50℃ for 30min to promote germination, mix nutrient soil and vermiculite in a volume ratio of 1:5 to form a cultivation substrate and transfer it to flower pots to promote germination The cotton seeds are inserted into the above-mentioned cultivation substrate and watered until the substrate in the flowerpot is soaked. When the two cotyledons of the cotton seedling are fully expanded, the cotyledons are inoculated with cotton aphid. The breeding conditions of parthenogenetic aphid are 14L:10D photoperiod, temperature 25℃ and relative humidity 75%. Control the population density of cotton aphids at 5 heads / cm 2 Below, to avoid the production of winged aphids.

Abstract

The invention discloses a cotton aphid sexupara, male aphid and female aphid indoor efficient inducing method and belongs to the field of agricultural pest prevention and control. Under natural conditions, cotton aphid sexupara, male aphid and female aphid only form one generation each year, 3-5 generations are needed to induce to obtain male aphid and female aphid if existing inducing methods areadopted, but asexual parthenogenetic aphid is always mixed in, and the existing inducing methods are troublesome in step. Aiming at the technical problem, the invention provides a parthenogenetic cotton aphid breeding method first and designs a sexual cotton aphid inducing device. Cotton seedlings at a cotyledon stage are transplanted into the device, one-year-old pathenogenetic aphid is inoculated and then continuously bred under low-temperature short light irradiation, sexupara and male aphid can be generated when the pathenogenetic aphid develops to be adult, and female aphid can be generated when sexupara develops to be adult. The inducing method is simple and convenient in operation, quick, efficient and capable of inducing cotton aphid sexupara, male aphid and female aphid in batches and orderly in development, is about to promote researches on basic biology of cotton aphid and lays a foundation for new cotton aphid prevention and control strategy 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 sex mother, sex female, and male aphids of cotton aphids. Background technique [0002] Cotton aphid (Aphis gossypii), also known as melon aphid, belongs to the Hemiptera Aphid family. It harms crops by sucking plant juice, secreting honeydew, and spreading plant viruses. Its host range covers more than 900 plants in 135 families, including grains, vegetables, fruits, forests, etc., which causes significant economic losses to the world's agricultural and forestry production every year. The occurrence and harm of cotton aphid is closely related to its unique reproductive mode. Its reproductive mode is plastic. It can choose parthenogenesis or sexual reproduction according to seasonal changes. Parthenogenesis can rapidly expand the population of cotton aphids during the plant growing season and increase the damage, whil...
