High-efficiency trap for male adults of rice leafroller and application of high-efficiency trap

Abstract

The invention relates to a high-efficiency trap for male adults of rice leafroller, which comprises a support, a lure core, a basin and a lure core hood. The lure core is mounted on the inner top surface of the lure core hood, and the lure core hood is mounted on the support and provided with a downward opening. A high-efficiency method of trapping the male adults of rice leafroller includes: adjusting a connecting part of the high-efficiency trap, and allowing a distance from the lower edge of the lure core hood to the surface of water in the basin to be no more than 2cm. Emission of sex pheromone can be effectively controlled through the 'lure core hood', the sex pheromone is led be close to the water surface to emit, the flying height of a moth around the lure core is reduced, and possibility that the moth is stuck is increased, and trapping efficiency is improved. In addition, the high-efficiency trap has the advantages that labor of setting up a conventional basin trap can be omitted, and the basin trap is reserved. Using the high-efficiency trap can evidently improve the efficiency of trapping the male adults of rice leafroller, saves time and labor, improve the resource utilization rate, and make it possible that the sex pheromone is used for standard collection and transmission.

Description

technical field [0001] The invention relates to the field of plant protection, and more specifically relates to a method and a device for attracting male adults of the same species by using an insect pheromone lure core. Background technique [0002] The rice leaf roller is one of the main pests of rice in Asia. It has a large area of ​​disasters every year in China. To prevent and control its damage, the cost of pesticides is high every year. It not only pollutes farmland, kills beneficial organisms, reduces biodiversity, but also stimulates rice. The reproduction rate of herbivorous insects such as planthoppers causes rampant growth and increases the use of pesticides again, so it is considered to be the initiator of the occurrence of pests in rice fields. In view of this, early monitoring of the occurrence dynamics of rice leaf roller is an important link to reduce the use of unnecessary chemical pesticides. [0003] At present, the main tools and methods for monitoring ...
