Embodiment 1

[0034] In this example, the carrier plant system used to propagate E. flavus is used. In this system, the carrier plant is rice, the alternative host is rice whitefly, and the natural enemy is E. flavus. The rice is "Chuangyou", "Jinjing", "Ningjing", "Hanyou", "Guangxian" or "Luoyou" rice.

[0035] Example 1 of the method for constructing a carrier plant system for propagating A.

[0036] In this example, rice is used as a carrier plant, rice whitefly is used as an alternative host, and Aphid aphids is used as a natural enemy to construct a carrier plant system. The rice is "Chuangyou", "Jinjing", "Ningjing", "Hanyou", "Guangxian" or "Luoyou" rice.

[0037] The embodiment 1 of the breeding method of the light yellow aphid aphid

[0038] In the present embodiment, the breeding method of the light yellow aphid aphid comprises the following steps:

[0039] 1) Clamp the small-leaf cages on the leaves of "Chuangyou" rice at the 4-leaf stage, release 100 rice whitefly adults in ...

Abstract

The invention relates to a carrier plant system for breeding encarsia sophia, a construction method, a breeding method and a method for preventing and controlling whitefly pests, and belongs to the technical field of biological prevention and control over agricultural pests. The carrier plant system is used for breeding the encarsia sophia, and the encarsia sophia has a good biological preventionand control effect on bemisia tabaci and trialeurodes vaporariorum. Carrier plant rice plants adopted for the carrier plant system are not harmed by the bemisia tabaci, the trialeurodes vaporariorum or other target pests, and therefore, when rice is regarded as carrier plants, nutrition sources of the target pests are not increased. Rice whiteflies belong to homoptera aleyrodidae, forage and breedonly on the rice, and thus cruciferae vegetables, solanaceae vegetables and other vegetables are not harmed. The encarsia sophia belongs to the hymenoptera, aphelinidae and encarsia, is an importantparasitic enemy of the bemisia tabaci and trialeurodes vaporariorum, and can conduct breeding with the rice whiteflies as hosts.

Description

technical field [0001] The invention relates to a carrier plant system, a construction method, a breeding method and a method for preventing and controlling whitefly pests for propagating Aphidia fragrans, and belongs to the technical field of biological control of agricultural pests. Background technique [0002] Carrier plant system, also known as banker plant system, natural enemy storage system or open natural enemy feeding system, a typical carrier plant system includes three basic elements: carrier plant, alternative host and beneficial organisms. Carrier plants, also known as savings plants or banker plants, can directly serve as food for alternative hosts or indirectly provide food or hosts for natural enemies, and can also serve as alternative hosts and provide habitat for natural enemies. Alternative hosts generally use arthropods with highly specific feeding habits, which are at the second level in the three-level nutritional relationship, relying only on carrier ...
