| Resumo: | Through experiments in Calvillo, Aguascalientes was determined that the populations of the guava weevil Conotrachelus dimidiatus can be estimated with pyramid traps baited with volatile compounds of guava. The attraction tests were conducted on commercial guava orchards for a period of five months during 2008 and 2009. The total catch of adults was higher in June and July of both years, with the beginning of the rainy season, decreasing towards the later months. The dispensers released the chemicals compounds up to 22 days depending on the mixture used. According to the results it is concluded that the strategy of trapping with chemical compounds can be an alternative to sample populations of the guava weevil. Additional compounds of the insect (pheromones) should be identified to increase the level of catches. |
