摘要
The trapping effects of yellow, blue, green, cyan and white sticky traps on adult Bradysia odoriphaga Yang et Zhang were studied in the field during its peak occurrence period. The results showed that yellow sticky trap received the best trapping effect on adult B. odoriphaga, follow by blue and green sticky traps, while cyan and white sticky traps received worse effects. The yellow sticky trap settled at south position was most attractive to adult B. odoriphaga, which had significant differences with tho^e placed at east and north positions （P 〈 0.05 ） ; the yellow sticky trap at hanging height of 0 cm showed significantly higher attractive- ness than those at heights of 20 and 40 cm.
