Efficacy of different baits and traps against Bactrocera dorsalis and cost evaluation

The efficacies of four different baits, four traps and nine common combinations against Bactrocera dorsalis were compared in order to provide a reference for optimizing the field control of this pest insect. The results showed that: 1) The total number of adults and fruit damage rate were the lowest in the treatment with the bait Conglü, with a low cost, which could be used for the control of B.dorsalis in peach orchards. Mier, Youer and Kangbi could significantly reduce the number of B.dorsalis, which can be selected or improved according to the actual situation in the occurrence area. Compared with the control group, the effect of the four baits on the female ratio was not significant. 2) In the combination of methyl eugenol oil agent with trap, it was recommended that conventional trap and new general-purpose trap for moths be used for monitoring and control, respectively, and it was not recommended to use mini fruit fly trap+mineral water bottle or new moth trap for monitoring and control. 3) The four combinations, i.e., conventional trap+methyl eugenol oil agent, special trap+food attracticide granules, yellow board 2 and yellow ball, performed well in their respective groups, and can be selected for use according to actual production needs.
