Abstract: 【Objective】 The Protaetia brevitarsis Lewis adults is one of the major pests to grapes, so this project aims to investigate the luring effect of fruits combined with manure, and different traps to Protaetia brevitarsis Lewis adults in vineyard. 【Method】 Different fruits such as watermelon, tomato, peach, melon and apple were selected to be combined with manure, and it was considered as a composite system to investigate the luring effect and the numbers of Protaetia brevitarsis Lewis adults on grapes in different treatments.Meanwhile, a four-arm olfactory was used to determine the tendency of Protaetia brevitarsis Lewis adults to the treatments of fruit-manure.The luring effects of different traps such as the barrel trap, a bookworm trap and the basin trap of Protaetia brevitarsis Lewis adults were investigated as well. 【Result】 The treatments of fruit-manure could actually reduce the numbers of Protaetia brevitarsis Lewis adults on grapes and showed the better effect to adults.There was significant difference between the two treatments as well.The total number of eggs and larvae in treatments was more than single attractor; the largest number of eggs and larvae were observed in the treatments of tomato-manure and peach-manure, respectively; In the tendency determination of Protaetia brevitarsis Lewis adults, the treatments of melon-manure and watermelon-manure showed the better attraction to female with 43.33% and 36.67%, respectively.And there were no significant difference between the two treatments; However, the selection coefficients of two treatments were significantly different with 0.33 and 0.20, respectively.Regarding the attraction to male, both of the attractant percent and the selection coefficient of melon-manure were the highest in all treatments with 33.33% and 0.23, respectively.In the barrel trap, a bookworm trap and the basin trap, the total number of Protaetia brevitarsis Lewis adults captured by barrel trap was significantly higher than that of other traps whether or not the lure was put in. 【Conclusion】 The treatments of fruit-manure showed better luring effect and reduce the numbers of Protaetia brevitarsis Lewis adults on grapes.The combination of barrel trap with P.brevitarsis lure can improve the trapping effect.
