بررسی نقش گیاه میزبان در شکار سوسک سرخرطومی حنایی خرما و سوسک شاخدار خرما با استفاده از تله های طعمه گذاری شده با فرومون و گیاه میزبان

Red palm weevil (RPW), RhynchOphorous ferrugineus Oliv. (Col.: Dryophthoridae), is one of the most important pests of different palms in Asia, North Africa and Spain. At present, it is an internal quarantined pest in Saravan region (Sistan and Balouchistan province, Iran). Date palm fruit stalk borer (DPFSB), Oryctes elegans Prell. (Col.: Scarabaeidae) is one of the most important pests of palm in Iran and Asia. Several experiments have been carried out on the role of host plant and pheromone on the attraction and trapping of RPW and DPFSB, both by pheromone-bait traps during 2006 in Saravan region. Analysis of results of study on the role of each of present components in trap ( pheromone and Plant bait) on attraction RPW showed that traps contain 2 kg date palm core in comparison with contiguous traps (contain only 2 pheromone) significantly attract more beetles (p
