بررسی کارائی پوشش های مختلف دورتنه درخت جهت پیشگیری از آلودگی به سرخرطومی حنایی خرما Rhynchophorus ferrugineus

Red palm weevil, Rhynchophorus ferrugineus Oliv. (Col.: Dryophthoridae), is one of the most important pests of date palms in Asia, North Africa and South Europe. In order to control this pest, infected trees are treated using aluminum phosphide (phostoxin) tablets. Currently, this pest spread in the provinces of Sistan and Baluchistan, Kerman, Hormozgan, Fars and Bushehr. Due to its feeding on the vascular tissue, R. ferrugineus causes the death of young and fresh date palms. Study on the effect of two types of trunk protective covering including aluminum mesh and nano fabric covers and control treatment (without cover) to prevent of infestation of R. ferrugineus on Mozafti date variety in the form of complete blocks design were conducted in Saravan and Jiroft cities during 2023-24. Covered and non-covered trees were wounded and for this purpose, the stemshoots on the tree trunk was removed. To install the cover, the upper and lower parts of the cover were closed with wire. Also, the lower part was covered with soil. In order to determination of infestation situation, the tested trees were visited for 6 months. The results showed that there was a significant difference between the treatments with cover and the control in terms of red palm weevil infestation. All the control trees were infected, while no infection was observed in the covered trees. According to the results of this study, in the climatic conditions of date-growing areas, aluminum cover around the trunk had better efficiency for preventing of R. ferrugineus and recommended.
