Embodiment Construction

[0033] In view of the above, through a lot of research and exploration, the present invention provides a kind of artificial propagation and application technology research of aphid gall midge, which has laid a good foundation for the resource investigation and biological control of aphid gall midge in my country. The specific production and reproduction methods are as follows:

[0034] 1. Clean seedling cultivation

[0035] 1.1 Seed selection and germination: Select broad bean seeds with a high germination rate, plump seeds, and a thousand-grain weight of about 1.8-1.9 kg. Soak the seeds in warm water at 21-23°C for 1-2 days before sowing, pour out the water after the seeds have fully absorbed the water, put them in plastic pots, cover them with wet gauze, and start sowing when the seeds germinate about 0.5 cm .

[0036] 1.2 Cultivation method: The cultivation medium is mixed with grass charcoal and vermiculite at a ratio of 1:2, and a small amount of perlite and soil can al...

Abstract

The invention discloses an artificial reproduction technological process and a method of application of aphidoletes aphidimyza. An aphidoletes aphidimyza mass reproduction technology and an application technology are characterized in that pea aphids, pea repaired tail aphids and aphis craccivora koch are reproduced massively by adopting broad beans, and the aphidoletes aphidimyza is reproduced by utilizing the pea aphids, the pea repaired tail aphids and the aphis craccivora koch. The aphidoletes aphidimyza mass reproduction technology and the application technology comprise the following processes: net seedlings are planted, aphids are raised, the aphidoletes aphidimyza is raised, old larvae are collected, and the larvae are saved in the pupal period. Adults are applied to field application and expanding reproduction after eclosion. An efficient and superior method technological process for reproducing aphidoletes aphidimyza is developed so as to solve the to-be-solved problems, and the method that the aphidoletes aphidimyza is used to prevent and control aphids can play a proper role in safe production of vegetables.

Description

technical field [0001] The invention relates to a method and application technology for artificial propagation of gall midges, in particular to a method and process flow for batch breeding of gall midges, belonging to the technical field of biological control of agricultural pests. Background technique [0002] Aphid gall midge ( Aphidoletes aphidimyza ) is a predatory natural enemy of aphids. According to literature reports, this insect can prey on aphids on 61 different crops, including many important agricultural pests, such as green peach aphid, prunus aphid, cotton aphid, bean aphid, radish aphid, Cabbage aphid, Spiraea aphid, etc. This insect is more lethal to aphids, and each larva can eat more than 50 aphids in its lifetime, and when the density of aphids is high, more aphids will be sucked to death. As early as 1916, Davis pointed out that aphid gall midge is a kind of biological control factor with great potential value for aphids. [0003] In my country, as ear...
