Abstract:According to the occurrence regularity of Bactrocera (Tetradacus) minax (Enderlein) in the orchard, a series of experiments were performed to compare the effect of different controlling methods. The results showed that B.minax adults trapping work should be done during the period of emergence peak: (7.6±1.8) insects were trapped per trap per day, while (1.8±0.3) insects were trapped per trap per day in spawning period. As for the distribution of traps in citrus orchard, traps should be setting in the junction area of citrus orchards and hybrid woods. The trapping number in junction area was (7.6±1.8) per trap, which was significantly higher than (4.5±1.2) per trap in orchard. But in spawning period, prevention in orchard was better than in junction area. The controlling effects about wormed fruits showed that there was no significant difference in trapping effect between the emergence peak period in the junction area and the whole adults hazard period in orchard.
