AbstractThe red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier), is one of the most destructive pests of date palm in United Arab Emirates. We conducted field trials in Abu Dhabi from May 2010 to April 2011, to evaluate the effect of weekly stirring of water and dates in the RPW pheromone trap on adults captured in brown and white traps, using a randomized complete block design with four treatments and five replications. Each trap contained: (1) a dispenser of the RPW male aggregation pheromone (Ferrolure™) containing 700 mg of the active ingredient (4-methyl-5-nonanol (90%) + 4-methyl-5-nonanone (10%)) at 95% purity; (2) an ethyl acetate (EA) dispenser (Weevil Magnet™) containing 40 ml of the active ingredient of EA at 98% purity; (3) 350 g of fodder date fruits; and (4) 4 L of water. Mean adults captured in white traps was 22.5 ± 0.50 and 16.8 ± 0.41 adults/trap/month with and without stirring, respectively, while in brown traps the mean was 39.9 ± 1.31 and 28.3 ± 0.51, respectively. The overall mean of adults captured was 31.2 ± 6.21 and 22.6 ± 4.81 adults/trap/month with and without stirring, respectively. The highest number of weevils caught was in the brown traps with stirring, while the lowest was in the white traps without stirring. The results of these trials suggest the use of brown traps containing aggregation pheromone, 350 g of date fruits, EA and water. It is necessary to stir the water with dates in the traps to increase their efficacy.

Different Sources

Field experiments were conducted during the periods from June, 2014 to March, 2015, in three date palm orchards located in Al Ain city, Abu Dhabi, United Arab Emirates, in order to evaluate the attraction efficacy for five different sources from the red palm weevil (RPW), Rhynchophorous ferrugineus Oliver (Coleoptera: Curculionidae), aggregation pheromone by using the standard four window black bucket trap.  The three orchards are characterized by having different levels of infestation incidence by red palm weevil. The Randomize Complete Block Design (RCBD) with five treatment and three replicates was used in each of the three orchards. The aggregation pheromone sources used in this experiment were: Rhyfer 700, Pherocon RDPW Lure, Ferrugitom 700, Weevil lure, and Ferrulure +. Collectively in the three farms as well as per each farm, Weevillure aggregation pheromone trap capture significantly lower average numbers of RPW adults than Rhyfer, Pherocon, Ferrulure, and Ferrugitom pheromone sources. Rhyfer pheromone is about 1.12, 1.18, 1.56 & 1.16 % more efficient than Pherocon, Ferrugitom, Weevillure & Ferrulure, respectively.
