چکیده

جورج پوینار، حشره شناسی پیشرو است که با تسلط بر حشره شناسی، نماتودشناسی و دیرینه شناسی، نقش چشمگیری در توسعه دیرینه‌شناسی کهربا داشته است. مطالعات بنیادی او در دهه‌های 1960 و 1970 روی نماتدهای Steinernema و Heterorhabditis، چرخه‌ زندگی، مسیر بیمایزایی و نقش و محل همزیست باکتریایی را روشن کرد و در معرفی نماتودهای بیمارگر حشرات به عوامل کنترل بیولوژیک، نقشی کلیدی داشت. پوینار پایه گذاری مهم در توسعه مطالعه نماتودهای بیمارگر حشرات و تثبیت این زمینه در چهارچوب آسیب‌شناسی کاربردی حشرات بود. در دهه های بعدی، تحقیقات بروز وی روی موضوع کهربا، تاریخچه تکامل حشراتی را که میلیون‌ها سال حفظ شده‌ بودند را آشکار کرد. بدین ترتیب هم الهام‌بخش داستان‌های علمی تخیلی بود و هم پایه گذار روش های استاندارد در مطالعه دیرینه‌شناسی زیست‌شناسی شد. پوینار با پیوند بین پدیده های زیست شناحتی در حشرات و نماتودهابا روند تغییرات دیرینه شناسی، هم پنجره ای جدید در زیست باستان شناسی باز کرد و نیز میراثی جاودان در سیستماتیک ، بوم‌شناسی و کنترل بیولوژیکی باقی گذاشت. وی با فهمی که در موضوعات دیرینه‌شناسی، حشره‌شناسی، تکامل و میکروبیولوژی داشت، اطلاعات ارزشمندی را روی فسیل‌های ارایه کردند. این نوشته با هدف معرفی نقش و جایگاه پروفسور پوینار در مسیر تکامل نماتودهای بیمارگر حشرات به عنوان عوامل کنترل زیستی نگاشته شده است. امیداوریم خوانندگان این نوشتار، از میزان علاقه، تلاش، پشتکار و جامع نگری جورج پوینار الهام بگیرند و این رویکرد همه جانبه نگر و عمیق را در تحقیق، تحصیل و زندگی بکارگیرند.
