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.展开更多

[ Method] The field trids were carried out by routine spraying method, and the control effects of mixtures of Beichuang （ Liangfenbao and Jianweikang） and less dose of phoxim than conrentional against B. odoriphaga larvae were examined. [Result] The results indicated that the control effects of mixtures （containing 14% of Liandeibao or Jian- veikang and 30% -40% less phoxim than conventional dosage） against B. odoriphaga larvae were 84.01% -2.46% and 81.07% -86.12%, respectively. The mntrol effects were equivalent to the conventional dose of phoxim （89.42%）. [ Conclusion] When Beichuang is mixed with phoxim in controlling B. odor/phaga arvae, the suitable reduction level of phoxim is 30% -40%.展开更多
