Thrip attractant and application thereof

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...

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 pheromones and lure core carriers (invention patent 201510619931.4 authorized by this project team, a pheromone containing lepidopteran insect sex pheromone Amphiphilic block copolymer micelles, and the declared invention patent 201610253705.3, a kind of insect pheromone microcapsules based on multi-walled carbon nanotubes, have achieved good slow-release effects) and trapping blue plates are highly effective comprehensive control Green measures for thrips
