Embodiment 1

[0026] Massive reproduction of the drones of Aphidia japonica with Bemisia tabaci as host insects

[0027] The main process of mass production and reproduction of A. figure 1 Shown, the concrete operation of applying this invention to produce 10000 drones is as follows:

[0028] 1) Cultivation of host plants

[0029] Sowing, raising seedlings and planting tomatoes according to conventional methods. Cultivate tomato plants in a greenhouse with sufficient light and controlled environmental conditions. When the seedlings grow to have 3 true leaves, a single plant is planted in a flower pot (caliber 18cm, depth 12cm), and a total of 10 pots are required. When the tomato grows to 8-10 true leaves, remove the heart leaves (it helps to keep the extended growth of the leaves and prevent the plants from growing too much), and keep the leaves when they grow to about 8cm long for later use.

[0030] 2) Primary host inoculation breeding

[0031] Put the prepared tomato plants i...

Embodiment 2

[0039] The selection of different secondary hosts by the wasp A. japonica

[0040] 1 Materials and methods

[0041] 1.1 Insects to be tested

[0042] Host insect: Bemisia tabaci type B Bemisia tabaci (Gennadius)

[0043] Parasitoid wasp: Aphid spp. Encarsia sophia (Girault & Dodd); Encarsia formosa Gahan; Eretmocerus melanoscutus Zolnerowich & Rose.

[0044] Tested host plants

[0045] kale Brassica oleracea L. var. capitata . Reserve when the potted cabbage grows to three true leaves.

Abstract

The invention discloses a method for producing a drone of light yellow encarsia amicula by taking encarsia formosa gahan as a breeding host. The light yellow encarsia amicula is a potential ideal natural enemy for controlling international insect pest bemisa babaci. Under natural conditions, the light yellow encarsia amicula are few, and capability of controlling the bemisa babaci is restricted to the utmost extent. Production and release of the drone are important for the light yellow encarsia amicula to control the bemisa babaci. In the invention, unmated drone of the light yellow encarsia amicula is released, the encarsia Formosa in a three age-prepupa stage is taken as a secondary host for breeding the drone, and high-quality and high-efficiency production of the light yellow encarsiaamicula is realized. The drone of the light yellow encarsia amicula produced by adopting the invention has the advantages such as short development duration, high emergence rate, large body and obvious increase of parasitic quantity after the drone is mated with a queen bee and the like and can be effectively used for biological control of mealywing insect pests such as the bemisa babaci and the like.

Description

technical field [0001] The invention relates to a method for quickly and efficiently propagating the drone of A. japonica, and furthermore provides a method for producing the drone of . Background technique [0002] Bemisia tabaci has become an international problem in agricultural production. The rise in the status of this pest is mainly related to the type B bemisia tabaci in recent years Bemisia tabaci (also known as silverleaf whitefly) successful invasion. Bemisia tabaci damages more than 600 species of host plants. After feeding on them, it not only weakens the growth of crops, but also causes physiological and metabolic disorders of plants, such as zucchini silver leaf reaction and irregular ripening of tomatoes. In addition, it can cause more serious indirect damage. The secreted honeydew not only affects the photosynthesis of plants, but also breeds the growth of mold, thereby reducing the price and quality of agricultural products. More importantly, it can be us...
