Problems solved by technology

Relying on color to trap and kill thrips has the problem of insufficient lure and poor effect
In addition, due to the wide variety of thrips, the attractant composed of chemical substances disclosed in the application number 201110101489.8 may be effective on some thrips, but not effective on others
At present, the occurrence and damage of thrips are still very serious, and there are still no effective green control measures. Therefore, the use of attractant

Embodiment 1

[0031] 1. The thrips insect pheromone lure is combined with the blue sticky insect board, and the lure components are 3-pyridinecarboxylate ethyl ester, anisaldehyde, p-tolualdehyde, 4-methoxybenzaldehyde=4:2 by mass :2:1 for preparation, its mixture is dissolved in n-hexane, with reference to the method disclosed in CN201510619931.4, using thrips attractant, amphiphilic block copolymer and deionized water as raw materials, two amphiphilic attractants containing thrips attractant are prepared. Pro-block copolymer micelles; put the amphiphilic block copolymer micelles containing the thrips attractant into a 2ml centrifuge tube to obtain the lure core I; wherein, the thrips attractant, amphiphile block copolymer, The mass ratio of deionized water is 3:20:7; the lure core I is suspended on the blue sticky insect board to form a thrips trap, and the trap is hung in the strawberry greenhouse, 10cm higher than the top of the plant, and the board is set The direction is perpendicular...

Embodiment 2

[0035]1. The thrips insect pheromone lure is combined with the yellow sticky insect board, and the lure components are 3-pyridinecarboxylate ethyl ester, anisaldehyde, p-tolualdehyde, 4-methoxybenzaldehyde=4:2 by mass: 2:1 is prepared, and the mixture is dissolved in n-hexane. With reference to the method disclosed in CN201510619931.4, using thrips attractant, amphiphilic block copolymer and deionized water as raw materials, the amphiphile containing thrips attractant is obtained. Block copolymer micelles; the amphiphilic block copolymer micelles containing the thrips attractant are put into a 2ml centrifuge tube to obtain the lure core I; wherein, the thrips attractant, the amphiphilic block copolymer, the The mass ratio of ionized water is 3:20:7; the lure core I is hung on the blue sticky insect board to form a thrips trap, and the trap is hung in the strawberry greenhouse, 10cm higher than the top of the plant, and the direction of the board is set Perpendicular to the fur...

Abstract

The invention discloses a thrip attractant and an application thereof. The thrip attractant is prepared from ethyl 3-pyridinecarboxylate, anisaldehyde, p-tolualdehyde and p-methoxybenzaldehyde in a mass ratio being (1-20):(1-20):(1-20):(1-10) through mixing; the substances are dissolved in n-hexane and slowly released in a carrier, lure is prepared, and the lure carrier of the thrip attractant is suspended on a blue or yellow pest sticking board. Control tests indicate that under the application of the thrip attractant, the control effect is similar to that of independently applied pesticides, and the control effect can be improved 3-4.5 times compared with that of the independently applied pest sticking board. When applied to control for thrips, the thrip attractant has the characteristics of being stable in product performance, long in persistent period, efficient and environment-friendly, luring numerous varieties and the like, the use quantity of chemical pesticides is substantially reduced, the damage rate of vegetables, fruits or flowers is also effectively controlled, sustainable development of green products is promoted, and a new thought is provided for the integrated control technique of thrip pests.

Description

technical field [0001] The invention belongs to the technical field of agricultural pest control, and in particular relates to a thrips attractant and an application thereof. Background technique [0002] Thrips is a general term for insects of the order Thysanoptera. The insects are small and often hide in flowers and young leaves to cause damage. At present, there are more than 7,700 species of thistles recorded in the world, and China accounts for more than 570 species (Majid et al. , 2011; et al. , 2014). So far, there are more than 2,000 species of Thrips family recorded in the world, belonging to about 276 genera in 4 subfamilies, and 315 species in 79 genera in China (Hu Qingling, 2013). Thrips have strong reproductive capacity, serious generation overlap, and high outbreak frequency. Global trade and climate warming have accelerated the spread and damage of thrips pests. Thrips pests have gradually become one of the most important agricultural pest groups in the w...
