    Effects of sex-pheromone attractant and black light on the trapping of rice stem borer (Chilo suppressalis) and the impact factors

    • Sex-pheromone attractant and black light trap are widely used in the forecast and prediction of rice stem borer (Chilo suppressalis). To compare the different effects of the two methods on trapping efficiency, field tests were conducted in Wenling, Zhejiang Province, from 2010 to 2014. The influences of the attractant material, trapping equipment, the number of overwintering larvae, and local climate factors on the trapping effects were investigated. It was found that, for the overwintering generation, the fluctuation dynamics on the amount of male moth trapped by sex pheromone attractant was generally consistent with that trapped by the light trap. By comparison, sex pheromone attractant method resulted in earlier and more peaks’ appearance of trapping amount, and significantly higher quantity than that obtained by the light trap. There was no significant difference in the trapping effect between different attractant materials and trapping equipments. The trapping amounts using both methods had significantly positive correlation to the number of overwintering larvae, which also closely related to the temperature in the field. As for the overwintering generation, the trapping amount was negatively correlated with the temperature, whereas it was positively correlated with the temperature for other generations.
