Problems solved by technology

Although experiments have confirmed that plant-derived volatiles can enhance the attractant effect of sex pheromones, there are still great differences in the combined effects of different components and dosages of the two.

Embodiment 1

[0028] 1. Trapping results of overwintering codling moth adults and first generation adults after wintering

[0029] 1. Study the trapping effect of lure types on overwintering adults and the first generation of adults after overwintering

[0030] 1-1. The trapping effect of lure types on overwintering adults

[0031] The lures with different composition combinations have significant effects on the total adult trapping capacity, male and female trapping capacity of the overwintering codling moth in pear orchards, and the specific results are shown in Table 1. Among them, SP is 0.25mg sex pheromone lure; PE is 0.25 mg pear ester lure; EEF is 0.25mg farnesene lure; SP+PE is the combination lure of 0.25mg sex pheromone and 0.25mg pear ester; SP+EEF is the combination lure of 0.25mg sex pheromone and 0.25mg farnesene wick; PE+EEF0.25mg pear ester and 0.25mg farnesene combination lure; 2SP is 0.5mg sex pheromone lure; 2PE is 0.5mg pear ester lure; 2EEF is 0.5mg farnesene lure.

Abstract

The invention relates to the field of plant pest control, in particular to lures and applications of botanical volatile composition compositions for trapping codling moths. The composition includes plant volatiles farnesene and pearate. The invention provides a lure containing a combination of two kinds of plant source volatiles, which solves the problem that the traditional sex pheromone lure can only trap males, and has a synergistic effect on the overwintering and first-generation adults.

Description

technical field [0001] The invention relates to the field of plant pest control, in particular to lures and applications of botanical volatile composition compositions for trapping codling moths. Background technique [0002] The codling moth Cydiapomonella (L.) is an important worldwide pest of pome fruit and also a major quarantine pest in my country. [0003] Because the codling moth is harmful to larvae bored fruit, its life history is uneven and generations overlap, and the main use of chemical pesticides in orchards leads to the increase of insecticide resistance year by year, which makes the monitoring of codling moth more difficult. [0004] The application of insect sex pheromones (Sex pheromone, SP) to control pests has the advantages of strong specificity, high efficiency, no pollution, and no harm to beneficial insects. It is an innovative technology that has been widely used in recent years. However, sex pheromones can only affect the behavior of males, but not...
