Problems solved by technology

[0010] The primary technical problem to be solved by the present invention is to provide a sex pheromone composition for attracting Spodoptera litura, which can greatly improve the sex pheromone trapping and killing technology of Spodoptera litura, and solve the current control efficiency of Spodoptera litura caused by multiple mating It has an important role and significance in the control and forecasting of Spodoptera litura sexually attracted pests
[0011] Another technical problem to be solved by the present invention is to provide a sex pheromone lure to lure Spodoptera litura, which can greatly improve the sex pheromone trapping and killing technology of Spodoptera litura, and solve the current control problems caused by multiple mating of Spodoptera litura. The problem of insufficient efficiency plays an important role and significance in the control and forecasting of Spodoptera litura sexually attracted pests

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] 1. Determination of Test Compounds

[0031] Based on the odor analysis of Spodoptera litura host plants, flowers, and insect-attracting plants in my laboratory, combined with literature reports, I purchased 9 compounds from the chemical market, see Table 1 for details.

[0032] Table 1

[0033]

[0034]

[0035] 2. Sex pheromones of Spodoptera litura attract male moths and their diurnal changes

[0036] In the field, the synthetic Spodoptera litura sex pheromone components cis 9 trans 11-tetradecadiene acetate and cis 9 trans 12-tetradecadadiene acetate at a ratio of 10:1 strongly attract the male moths, Observing and taking pictures at night in the field found that the male moth flew to the trap in a Zig-zag curve, and then eagerly looked for the entrance to enter the trap, see Figure 1b . The experimental results show that th...

Abstract

The invention discloses a sex pheromone composite for luring prodenia litura and a luring core thereof. The sex pheromone composite is characterized in that: the sex pheromone composite consists of the following components of sex pheromone and phenylacetaldehyde, wherein the sex pheromone consists of cis-9,trans-11-tetradecadienoic acetate and cis-9,trans-13-tetradecadienoic tetradecadienoic which are mixed in a mass ratio of 3-13: 1; and the phenylacetaldehyde is used as a synergist and accounts for 20 to 60 percent of the total mass of the components. The invention also discloses a related luring core. The researches of the invention prove that the phenylacetaldehyde can greatly improve the technology of luring and killing prodenia litura by sex pheromone, solves the problem of low control efficiency caused by multiple mating of the prodenia litura in the prior art, plays an important role in and has a great significance for the control, detection and reporting of the sexual luring insects such as the prodenia litura.

Description

technical field [0001] The invention relates to a sex pheromone for attracting noctuid moths, a synergist composition thereof and related lure cores. Background technique [0002] The backwardness of pesticide equipment, the implementation system, and the lack of farmers' scientific knowledge have resulted in the amount of chemical pesticides per unit of farmland in my country being much higher than the global average. Excessive abuse of pesticides has brought great damage and threats to my country's environmental ecology, agricultural product safety, and human health. The increase in pest resistance has also brought new challenges to its control. Reducing agricultural non-point source pollution caused by chemical pesticides is the trend and consensus of international scientific and social development. Therefore, semiochemical technology is generally considered to be one of the four basic technologies of integrated pest management together with natural enemy insects, microb...
