Problems solved by technology

However, due to the characteristics of aphid aphids that reproduce bisexually and reproduce drones in a self-parasitic manner, it brings certain difficulties to their mass reproduction. At present, there is no mature mass reproduction technology in my country.

Embodiment 1

[0050] Example 1: Mass production and reproduction of Aphididae

[0051] The mass production and reproduction process of the yellow aphid bee is mainly as follows figure 1 As shown, the details are as follows:

[0052] 1. Collect and reproduce the bee species of Aphididae

[0053] (1) Collecting bee species: Collect the whitefly nymphs parasitized by the small yellow aphid, that is, black pupae on the leaves of field plants where whiteflies are severely infested;

[0054] (2) Purification and optimization of bee species: The collected parasitic black pupae of Aphididae were placed at 25-27°C and RH.60-70% to develop, and the queen bee emerged and transferred to the body of the whitefly nymph , And then select good bee species by testing the parasitism rate, emergence rate, fecundity, sex ratio, storage characteristics and the ability to search for the target pest eggs;

[0055] (3) Breeding of bee species: expand the female and male species of Aphis sibiricus respectively, and accumul...

Embodiment 2

[0080] Example 2: Comparative experiment

[0081] Comparative experiment 1: Screening of host plants

[0082] (1) Materials and methods

[0083] i) Test insects

[0084] Bemisia tabaci was collected from tomato plants in the greenhouse of Beijing Academy of Agriculture and Forestry Sciences.

[0085] The yellow aphid (black pupae) came from the Agricultural Experimental Station of Texas A&M University, USA.

[0086] ii) Host plant

[0087] Beans, cucumbers, cotton, poinsettia, cabbage, sweet potatoes, and tomatoes were the test hosts.

[0088] Beans, cucumber, cabbage, and tomato seeds were purchased from the Special Vegetable Center of the Vegetable Institute of Beijing Academy of Agriculture and Forestry Sciences. Cotton and sweet potatoes were provided by the Institute of Zoology, Chinese Academy of Sciences, and poinsettia was purchased from a Beijing supermarket.

[0089] iii) Experimental conditions and equipment

[0090] It is carried out indoors, the temperature is controlled at 25-...

Abstract

The invention discloses a pale yellow Encarsia chalcid artificial propagation production method, comprising the following steps: collection and propagation of the pale yellow Encarsia chalcid species; host production; whitefly inoculation reproduction and development; inoculation and breeding of chalcid; drone cultivation; chalcid and whitefly separation; pupae collection; card making; and breeder selection. The proposal of the invention helps to improve the superior bee species selection, propagation and release, and realizes the high-quality, high-efficiency and high-scale reproduction of pale yellow Encarsia chalcid; moreover, the method is suitable for large-scale production and is applied to the technical field of agricultural pest biological control to prevent and control the greenhouse whitefly and other agricultural pests to meet production needs.

Description

Technical field [0001] The invention relates to a process for the reproduction and production of bees, in particular to a production method for the artificial reproduction of small yellow bees, belonging to the technical field of biological control of agricultural pests. Background technique [0002] Whiteflies have caused huge economic losses all over the world, with an average annual loss of more than 300 million US dollars. In recent years, my country has not only increased the incidence of greenhouse whiteflies, but also the invasive alien pests whiteflies have rampantly endangered our agriculture. Because whiteflies are waxy, tiny individuals, hidden habits, strong drug resistance, and difficult chemical control, they pose a serious threat to crop production. For many years, countries all over the world have been seeking ways and methods of biological control. Parasitic wasps are an important natural enemy resource for whiteflies, and there have been many successful cases o...
