Device for trapping coccinella septempunctata for oviposition

Abstract

The invention belongs to the technical field of insect breeding and particularly relates to a device for trapping coccinella septempunctata for oviposition. According to the device for trapping the coccinella septempunctata for oviposition, a pea seedling carrying sufficient megoura japonica is used as a trapping material, by use of the taxis of the coccinella septempunctata to aphids, the coccinella septempunctata and the pea seedling carrying the sufficient megoura japonica are placed in an oviposition container for trapped oviposition, the trapping effect is obvious, the coccinella septempunctata can be trapped together, and gathered oviposition of the coccinella septempunctata is facilitated; a smooth black PE bag which has the high oviposition amount and is 0.1-0.2 mm thick is used asan oviposition carrier, the oviposition rate of the coccinella septempunctata and the recovery rate are effectively increased, the problems that the oviposition amount of the coccinella septempunctata and the recovery rate of eggs are low is solved effectively, and the method plays an important role in guaranteeing population reproduction of the coccinella septempunctata.

Description

technical field [0001] The invention belongs to the technical field of insect cultivation, and in particular relates to a device for luring ladybugs to lay eggs. Background technique [0002] Aphids are extremely harmful pests in agriculture, causing irreversible damage to plants and the environment, and have caused considerable disasters in both greenhouses and fields. At present, the control of aphids is mainly based on pesticide control. Although the effect is remarkable, it inevitably causes great chemical pollution due to excessive use of chemical pesticides, causing secondary damage. [0003] Coccinella septempunctata L. is one of the dominant natural enemies of aphids. Coccinella septempunctata L. belongs to the order Coleoptera and the family Coccinellidae. It is an important predatory natural enemy of aphids on major crops such as wheat, cotton, oilseeds and vegetables. Research at home and abroad has proved that the use of seven-star ladybug to control aphids is a...

Problems solved by technology

[0004] Among the existing indoor artificial breeding methods of seven-spot ladybug, there is no mature system method, which can enable the seven-spot ladybug to reproduce stably and maintain good traits.

In the current method, there are always problems that the seven-star ladybug can complete the life cycle, but the fecundity is not strong, the research on the method of laying eggs is lacking, and a large number of subculture cannot be realized.

The test insects of the seven-spot ladybug rely on field collection, and there is no stable source of artificial continuous multi-generation breeding, which limits its research work and limits its release and application in the field as a natural enemy insect
