In recent years,bark beetles have seriously affected the local apricot resources in Turpan,Xinjiang.The preference of Scolytus seulensis Murayama and the Scolytus rugulosus Ratzeburg host on Armeniaca spp.to sticky traps with six colors(red,yellow,blue, green,black,and white)was investigated.The results showed that different sticky traps had various attraction effects on bark beetles. The best attraction effect of sticky trap on S.seulensis was found in red,followed by black;while the best attraction effect of sticky trap on S.rugulosus was observed in black,followed by red.Sticky traps with other colors had no obvious attraction effects.The average trapping number of S.seulensis was 11.8±5.0 for sticky trap in black,and average trapping number of S.rugulosus was 16.4±3.0 for sticky trap in red.Moreover,it also could be seen that these two kinds of bark beetle had different emergence peak period,which was in the beginning of June for S.seulensis,and in the middle of July for S.rugulosus.
