Application of (2S,8Z)-2-butyryl acyloxy-8-heptadecene

Abstract

The invention discloses the application of a compound (2S,8Z)-2-butyryl acyloxy-8-heptadecene with the structural formula shown as the formula (I). The compound is used for preparing a chrysanthemum gall midge sex attractant. Shown by the experiment for the trapping effect for the chrysanthemum gall midge, the compound (2S,8Z)-2-butyryl acyloxy-8-heptadecene has strong attraction effect to the chrysanthemum gall midge. The product has proper price, favorable social and ecological benefits and suitable generalization and application.

Description

technical field The present invention relates to the application of (2S, 8Z)-2-butyryloxy-8-heptadecene. Background technique The chrysanthemum gall midge Rhopalomyia longicauda belongs to the family Diptera and is widely distributed in my country. It is an important pest on chrysanthemums, Artemisia annua and other Compositae plants. It mainly damages plant growth points, young leaves and flower buds through larvae, forming galls. , resulting in slow plant growth, dwarf deformity, and reduced flower buds. Since the larvae are hidden inside the gall, it is difficult to directly contact and kill them. During production, parathion, monocrotophos and other systemic pesticides have been used for control for a long time. As a result, pesticide residues have seriously exceeded the standard. , and environmental pollution issues. The new method of controlling chrysanthemum gall midge with high efficiency, non-toxicity and pollution has certain scientific significance and applicatio...
