Effect of Different Concentrations of M2ITM Pheromone Dispensers and the Impact of Water and Paraffin in Pheromone Traps for Rhynchophorus Ferrugineus (Coleoptera: Curculionidae) Management in Tunisia
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 6, Issue 5
Abstract
Red palm weevil is considered nowadays one of the major threats to palm trees worldwide. Due to the current issue towards the use of environmentally friendly control measures, dealing with this pest by mass trapping was used in this study. In order to enhance the current management practices to control the pest , field studies were conducted to know the attractiveness of red palm weevil to 3 concentrations of polymers in M2ITM dispensers in comparison to ISCA capsules, and to test the effectiveness of putting water inside the traps in the adults’ attraction. Besides we tested the impact of three solutions: bare paraffin, paraffin mixed with water and bare water in order to evaluate the best solution that attract more adults of Red palm weevil. Studies indicated that the concentration 0.5 % and 1 %( of polymers) attracted significantly more number of weevils. Studies revealed also that there wasn’t significance in putting water inside traps. The solutions tested inside the traps proved that paraffin is the best substance that bans more adults to escape from trap. This study indicated the existence of red palm weevil throughout the year but with lower adults capture in the study period (October-December) .We presented climatic data in details mainly temperature and Relative humidity. These parameters were main explication for the lower rate of RPW adults captured in baited traps. Pheromone traps baited with M2I dispensers can be placed in fields for better IPM for RPW.
