چکیده

مگس میوه زیتون Bactrocera oleae (Rossi) از آفات مهم زیتون می باشد و هم اکنون حسب شرایط آب و هوایی خسارت قابل توجهی به محصول زیتون وارد می نماید. در این تحقیق، ماده جلب کننده مگس میوه زیتون به نام شیمیایی (olean) 1,7-dioxaspiro[5.5]undecane از گروه ترکیبات جلب کننده‌ای است طی چندین مرحله شیمیایی با موفقیت ساخته شد. این ترکیب جلب کننده حلقوی ابتدا از واکنش شیمیایی بین الکل محافظت شده 3-بوتین-1-ال و گاما-والرولاکتون بدست آمد و سپس محصول با احیای کاتالیستی هیدروژنه شده و بعد از قرار گرفتن تحت شرایط اسیدی به olean تبدیل گردید. قدرت جلب کنندگی فرومون سنتز شده مگس میوه زیتون، Bactrocera oleae ، با دز‌های 1، 2، 5، 50 و 100 میلی گرم در مقایسه با فرومون خارجی اگریسنس در 4 تکرار در یک باغ زیتون به مساحت 3 هکتار در منطقه کلج (طارم سفلی- قزوین) ارزیابی شد. تله‌های چسبی زرد رنگ در قسمت میانی و سمت جنوبی درخت‌ها و به فاصله حداقل 100 متری از هم دیگر نصب شد. فرومون ها به مدت یک ماه در باغ نصب و میزان شکار مگس هر هفته شمارش وهمزمان تله چسبی به طور هفتگی تعویض گردید. تجزیه واریانس داده های این آزمایش نشان می دهد که در طی دو هفته اول میزان جلب تله های تولید شده با دز های 50 و 100 با نمونه خارجی اختلاف معنی داری ندارد و بیشترین شکار را در این بررسی داشته ولی از هفته های سوم به بعد مقدار جلب مگس در مقایسه با نمونه خارجی کاهش یافته است.

چکیده [English]

The olive fruit fly Bactrocera oleae (Rossi) is an important pest cause a lots of damages these days in various climates condition. 1,7-Dioxaspiro[5.5]undecane (olean) as a attractive compound of the olive fruit fly was prepared successfully by several chemical steps. At first, this cyclic attractive compound was prepared from the reaction of the protected alchohol 3-butyn-1-ol and -valerolactone, followed by catalytic hydrogenation and finally treating with an acidic condition afforded olean. Attractiveness of Iranian synthesized pheromone a, at doses of 1, 2, 5, 50 and 100 mg was compared with non-Iranian synthesized pheromone and a control treatment (sticky yellow trap without pheromone) in 4 replications in an olive orchard (3 ha) at Kalaj region (Trom Sofla, Ghazvin) in 2010. Sticky traps (20×25 cm) were placed at the middle and southern part of trees. Distance between traps was 100 m. Pheromones were left in the traps for one month during which their catches were recorded weekly. Each week the sticky traps were renewed. Analysis of variance showed that during the first two weeks, Iranian synthesized pheromone at 50 and 100 mg doses had the highest catch rates which were not significantly different for non-Iranian synthesized pheromone catch rates. Analysis of variance showed that during the third week of study, there were significant differences in catch rates of Iranian synthesized pheromone and non-Iranian synthesized pheromone.
