Abstract :
Red palm weevil (RPW)Rhynchophorus ferrugineus Olive. (Col,: Dryophthoridae) is the most important and most dangerous pest under the internal quarantine law in Iran. larvae cause the death date palms by feeding the tissues (vines) and emptying the trunk. Pest control chemical methods (spray, injection, fumigation and soil, irrigation pesticide application) are part of integrated pest management programmes. This research was conducted to investigate the efficacy insecticide Flupyradifurone20% with trade names Sivanto® and injection device (5cc automatic syringe, initiated and re-designed by the author) and injection trunk technique for controlling red palm weevil in randomized complete block design with four treatment and four replications. The results showed there was a significant difference between the treatments for the dead and live larvae and adult at 1% level. So Flupyradifurone20% treatments with concentration of 100ml (20gr active ingredient) injection with 100ml water and Flupyradifurone20% with concentration of 100ml (20gr active ingredient) injection rates the average of 9.7 and 8.3 per palm tree, respectively had the most effect on controlling the larvae in compared to Confidor35% injection and spray Flupyradifurone20% on the trunk. Experimental results showed that injection of the pesticide into a trunk is a suitable and effective method for controlling RPW and device 5cc automatic syringe can be used for injection into the trunk.
