Failed male annihilation of Bactrocera cucurbitae

On the Japanese island of Iheya, experiments were conducted to annihilate the male population of Bactrocera cucurbitae (EPPO A1 pest) through cue-lure traps. However, the mating rates of mature females did not decrease significantly, compared to these on control islands and the infestation rates of melons were not always lower than in the previous year.
Therefore, the authors conclude that suppression of B. cucurbitae reproduction through male annihilition with cue-lure traps is problematic.
