Abstract: Arhopalus rusticus (L.) is a serious forest insect pest attacking pine, cypress and other trees. In recent years, A. rusticus infests severely in Tai'an, Weihai and other areas of Shandong province. Pheromone trap, baited-wood trap and release of two species of parasitic natural enemy adults, Scleroderma guani and Dastarcus helophoroides, were tested for their control of A. rusticus larvae in both laboratory and pine forest. No II pheromone trap obtained the best control, with catch size of 69 per pheromone trap in 30 d, followed by baited-wood trap (63 per trap). In laboratory, control efficiency of S. guani against A. rusticus larvae reached as high as 71.00%, but was not significantly different between ratios of S. guani to A. rusticus larvae. S. guani preferred trees of 10~15 cm trunk diameter and afforded parasitism rate of 8.43% at the highest when released in pine forest. D. helophoroides showed higher control efficiency against A. rusticus in both laboratory and pine forest, with parasitism rate reaching up to 80.02% at ratio of D. helophoroides adults to A. rusticus larvae being 5:1 in the laboratory and 58.80% when released in pine forest. Our results show that these pollution-free techniques are effective against A. rusticus.
