Identification of hemocytes in sugar beet weevil, Lixus incanescens (Coleoptera: Curculionidae)
نویسندگان
چکیده
نقش سلولهای خونی به عنوان اجزای اصلی دفاع فیزیولوژیک حشرات مهم گزارش شده است. اولین فاکتورهای سیستم گردش خون هستند که در مقابله با انواع تنشها و عوامل بیگانه مشارکت می کنند. تحقیق حاضر، چهار نوع هموسیت همولنف لارو سن چهارم خرطوم بلند دمبرگ چغندرقند شناسایی شد شامل پروهموسیتها، گرانولوسیتها، پلاسموتوسیتها انوسیتوئیدها هستند. بزرگترین از نظر اندازه بودند مجموع فراوانی گرانولوسیتها لاروهای سنین سوم (حدود 70%) ( بیش 75%) بالاتر سایر سلولها بود. این یافته ها، گام مطالعات ایمنی شناسی حشره، دارای اهمیت باشد.

BACKGROUND Owing to the changing climate, narrow crop rotation, and changes in insecticide application practice, sugar beet weevil (SBW) (Bothynoderes punctiventris Germar) has become the most important economic pest in sugar beet. To develop alternative control methods, an area-wide (AW) control program using aggregation pheromones was implemented over 4 years on an area of 6 and 14.8 km2 in e...

The objective of this study was to estimate the silky cane weevil rate of dispersal under near-natural conditions inside a screened enclosure where an array of buckets was baited with cut sugarcane stalks. One hundred weevils were released and weevils inside the buckets were counted hourly for 8 h, and then 24 and 48 h after release. A passive diffusion model was used to estimate the weevil’s d...
