Embodiment 1

[0015] After preparing different mixtures of benzyl alcohol, benzaldehyde and phenylacetaldehyde in appropriate proportions, 0.05 ml of the mixture was diluted with 2 ml of dichloromethane and added dropwise to rubber cores to make lures for field trials.

[0016] In field experiments, water basins were used as traps. Add an appropriate amount of water to the water basin, and add a little washing powder to the water. Put the lure core through the iron wire and place it horizontally on the water basin. The lure is located in the center of the water basin, about 1 cm away from the water surface. Put the lure core into the field every evening, take it back the next morning, and count the number of insects trapped in the water basin. 3 replicates per treatment. Blank control.

Abstract

An attractant for the male moth of rice leaf roller is proportionally prepared from phenylmethanol, phenylformaldehyde and phenylacetaldehyde the rough mixing. Its advantages are high effect and high safety.

Description

technical field [0001] The invention relates to an attractant for Cnaphalocerocis medinalis male moths, which belongs to the field of pest control. Background technique [0002] Rice leaf roller is an important pest distributed in the main rice producing areas in my country, and has the habit of long-distance migration. [0003] The rice leaf roller eats rice tender leaves or flag leaves with larvae at the tillering stage, booting stage, and heading stage, which has a great impact on yield. When the rice is damaged at the tillering stage, it will seriously affect photosynthesis and hinder the growth and development of rice. If the flag leaf of rice is damaged, it will have a more direct impact on the yield, resulting in a decrease in the thousand-grain weight and an increase in the grain rate. Generally, the rice yield will be reduced by 10-15%, and the serious one can reach more than 50%. [0004] For a long time, the control of rice leaf roller has been mainly controlled...
