Dispensers for mating disruption against currant clearwing moth Synanthedon tipuliformis (Cl.) in currant crops.

摘要

During 2005-2006 the trials were conducted on 4 different areas of currant crops, ranging from 1 ha to 5.16 ha. The pheromone dispensers were applied on experimental plots in dosage 400 and 500 dispensers per ha. The highest number of currant clearwing moth caught by pheromone traps on mating disruption plots was only 12 males comparing to the control plots, where the number of male individuals was much higher and ranged from 163 to 427 males per trap per season. On pheromone plots the number of larvae inside shoots was similar to the one on control plots with chemical control. The results of performed trials showed that mating disruption could be considered as a good alternative for conventional control of currant clearwing moth and on important element of IPM currant production.
