Two new records of spider mites (Acari: Tetranychidae) from Iran
خانواده‌ی Tetranychidae گونه‌های زیادی دارد که همگی آفات محصولات کشاورزی هستند. دو گونه از کنه‌های این خانواده، Eotetranychus uncatus Garman و E. potentillae Begl. et Mitr برای اولین‌بار از ایران گزارش می‌شوند. گونه‌ی اول از شهرستان مراغه روی آلوچه و گونه‌ی دوم از گچسر (واقع در جاده چالوس) روی تمشک در تابستان 1388 جمع‌آوری شد.
متن کاملToward spinning artificial spider silk.
Spider silk is strong and extensible but still biodegradable and well tolerated when implanted, making it the ultimate biomaterial. Shortcomings that arise in replicating spider silk are due to the use of recombinant spider silk proteins (spidroins) that lack native domains, the use of denaturing conditions under purification and spinning and the fact that the understanding of how spiders contr...

15 صفحه اولThe effect of spinning forces on spider silk properties.
A new forced silking procedure has been developed that allows measurement of the low forces involved in the silking process and, subsequently, retrieval and tensile testing of the samples spun at the measured silking forces. A strong correlation between silking force and tensile behaviour of spider silk has been established. Fibres spun at high silking force--compared with the conventional yiel...
