Embodiment 1

[0012] Embodiment 1: sexually mature chestnut weevil adults are placed in a transparent rearing box with a cover with air holes according to the ratio of male to female ratio of 2:3. In the box, 11g of chestnut fresh leaves and 0.4g of artificial feed are used for each worm. The amount is placed, and the fresh leaves and feed are replaced once a day. The breeding environment is: humidity 40%, light intensity 100lux, light time 12 hours / day, and temperature 35°C. After 3 days of cultivation, young chestnut fruit branches with flowers for spawning are placed, light intensity is adjusted to 2lux, and temperature is controlled. Cultivate at 22°C for 6 hours. After checking the oviposition, the shoots are taken out in a transparent rearing box and cultured for 5 days under constant environmental conditions, during which the freshness of the shoots is guaranteed. After 5 days, peel off the peel carefully, and transfer the larvae to the artificial breeding box. The environment is: hu...

Embodiment 2

[0013] Embodiment 2: the sexually mature Chinese chestnut weevil adult is placed in the transparent rearing box with air holes on the cover according to the ratio of male to female ratio of 2:3, and the amount of 0.5g artificial feed of 9g chestnut fresh leaves per head worm is placed in the box each time. Place the amount and replace the fresh leaves and feed every day. The breeding environment is: humidity 70%, light intensity 500 lux, light time 16 hours / day, and temperature 35°C. After 5 days of culture, young chestnut fruit branches with flowers are placed for spawning, light intensity is adjusted to 8 lux, and temperature is controlled. Cultivate at 24°C for 8 hours. After checking the spawning situation, the shoots are taken out in a transparent rearing box and cultured for 6 days under constant environmental conditions, during which the freshness of the shoots is guaranteed. After 6 days, peel off the peel carefully, and transfer the larvae to the artificial breeding b...

Embodiment 3

[0014] Embodiment 3: sexually mature chestnut weevil adults are placed in a transparent rearing box with a cover with air holes according to the ratio of male to female ratio of 2:3. In the box, 11g of fresh chestnut leaves and 0.5g of artificial feed are used for each worm in the box. The amount is placed, and the fresh leaves and feed are replaced once a day. The breeding environment is: humidity 40%, light intensity 500 lux, light time 12 hours / day, and temperature 20°C. After 3 days of culture, place young chestnut fruit branches with flowers for spawning, adjust light intensity 2 lux, and control temperature Cultivate at 26°C for 8 hours. After checking the spawning situation, the shoots are taken out in a transparent rearing box and cultivated for 5 days under the condition of constant environmental conditions, during which the freshness of the shoots is guaranteed. After 5 days, peel off the peel carefully, transfer the larvae to the artificial breeding box, in the envi...

Abstract

The invention provides a chestnut weevil artificial feed, cultivation method and application of mature larvae. The feed contains peanuts, wheat, soybean, corn starch, sugar, multivitamin and carotene. The cultivation method comprises the following steps of: putting pubescent male and female chestnut weevils, fresh chestnut tender leaves and a feed into a feeding box, performing cultivation under certain conditions for 3-5 days, putting chestnut young fruits with flowers and young fruits of other quercus species, and performing cultivation under certain conditions for 6-8 hours so as to ensure that chestnut weevils perform natural spawning; further cultivating the young fruits subjected to spawning for 5-6 days, stripping off peels, transferring larvae into a feeding box with a feed, and performing cultivation under certain conditions for 35-40 days so as to obtain mature larvae; and further inducing nymphosis of the mature larvae. The obtained mature larvae or pupae can be used as cultivation hosts of scleroderma guani xiao et Wu and other parasitic wasps or breeding materials for later use. The chestnut weevils are used for artificial breeding for the first time, the method is simple, feed ingredients are easy to obtain, and magnified breeding is easy to perform.

Description

technical field [0001] The invention belongs to the technical field of insects, and in particular relates to the artificial breeding of chestnut weevils. Background technique [0002] Chestnut weevil (Curculio davidi Fairmaire) belongs to Coleoptera, Weevilidae, also known as chestnut weevil, chestnut weevil. It is distributed in various chestnut producing areas in China. It damages chestnuts with larvae. Up to 80% or more. The patent applicant has discovered but not disclosed: Scleroderma guani Xiao et Wu can effectively parasitize chestnut weevils in an artificial breeding environment, which makes it possible to control chestnut weevils through artificial intervention and using Scleroderma guani Xiao et Wu A biological control tool with great potential. Carrying out the prevention and treatment of chestnut weevil with Scleroderma guanzi requires artificial breeding and rejuvenation of Scleroderma guanzi. In this process, the patent applicant has discovered but not disclo...
