Embodiment 1

[0016] Take the production of 100,000 bees as an example to further illustrate:

[0017] (1) Preparatory greenhouse: 2.5 square meters for clean seedling production, 2 square meters for whitefly inoculation, 2 square meters for whitefly nymph development, 1.5 square meters for breeding bees, a total of 8 square meters; each workshop is isolated from each other to avoid insects Fleeing infection.

[0018] (2) Production of clean seedlings: mix soil and sow 10 tobacco seeds in the seedling tray, 1 in each hole; transplant for the first time when growing to a height of 5 cm (into a small pot), and transplant for the second time when growing to a height of 5 cm (Move into a large pot), when it grows to 10 leaves, pinch the tip and prepare to catch insects. The workshop requires a clean and airtight environment in order to cultivate clean tobacco seedlings without pests and diseases (without pesticide treatment); the temperature is kept at 25° C., the relative humidity is kept at ...

Abstract

The present invention provides a technological process for large-scale breeding bernisia tabaci genn by using tobacco and industrial production of eretmocerus spp. by using nymph of bernisia tabaci genn. Said invention adopts four-chamber eretmocerus spp. breeding method, mechanical collection, separation and purification, low-temp. short-period storage and annual industrial breeding eretmocerus spp. The host plant is tobacco leaf, it can bear lots of bernisia tabaci genn, and is high in production efficiency and is favorable for collection, the bernisia tabaci genn can be used as host of eretmocerus spp, so as to ensure controlling effect in field.

Description

technical field [0001] The invention relates to the technical field of industrial production of beneficial insects (Aphididae wasp) and biological control of agricultural pests. Background technique [0002] At present, Bemisia tabaci has become a major pest in the world, which can damage more than 600 kinds of plants and transmit more than 70 kinds of viruses. It has become the most extensive host range and the most serious damage in my country's agricultural production, especially in the production of protected vegetables. one of the pests. Due to the characteristics of Bemisia tabaci's rapid reproduction, overlapping generations, and waxy body surface of adults, the use of chemical pesticides for control will not only bring about problems such as drug resistance, pest re-emergence, and pesticide residues, but also have little control effect. However, the parasitic natural enemy usually used to prevent and control whitefly in greenhouses, Limadidae, is ...
