Performance of different traps for mass trapping of sycamore wood borers (Case Study: Karaj city)

Due to the increasing damage caused by wood-boring pest of Platanus orientalis in the urban environment, it is required to analyze the different preventive care for this species. This study aimed to investigate the performance of various traps for mass trapping of sycamore wood borers in Karaj city for two years. Four different experimental stations were selected across the city to install the required traps. Each station was instrumented with nine light traps (i.e. white, yellow, and black light), six sticky traps and six bucket traps (i.e. white, yellow, orange, red, blue, and green) and 10 cylindrical traps. Pest collection was started in May 2015 and continued till October 2016 at weekly intervals. The data were statistically analyzed using GLM procedure by using SPSS software ver.16. Trapped samples include three families including Buprestidae, Cerambycidae and Scarabeidae. The results indicated no significant difference between bucket trap (1.9), sticky trap (1.38) and cylindrical trap (2.55) in wood borer absorption, but the wood borer absorbed by light trap (27.33) was significantly higher than those observed by other traps. Within the light traps, the black light (42.33) and the white light (12.67) absorbed the highest and the lowest amount of wood borers, respectively. Finally, it could be suggested that the most appropriate trap for mass trapping of sycamore wood borers is light trap. Also, white and orange colors are more efficient in attracting the sycamore wood borers.
