| کفشدوزک Muls. Cryptolaemus montrouzieri و کفشدوزک نقاب‌دار دولکه‌ای،Chilocorus bipustulatus (L.) از جمله شکارگرهای مهم شپشک‌های خانوادۀ Diaspididae و Eriococcidae در ایران می‌باشند. از جمله روش‌های شیمیایی مبارزه با شپشک‌ها استفاده از روغن‌های معدنی بوده که سازگاری بالاتری با محیط داشته و با سرعت نسـبتاً زیادی در محیط از بین رفته و خطر بـروز مقاومـت یـا طغیـان آفـات ثانویه در رابطه با این ترکیبات بسیار کم است. در این مطالعه اثر روغن ولک روی حشرۀ کامل و سنین مختلف لاروی کفشدوزک C. montrouzieri و C. bipustulatus روی برگ‌های مرکبات در شرایط باغ مورد برررسی قرارگرفت. ابتدا سنین مختلف لاروی و حشرات کامل کفشدوزک‌های مزبور بهصورت جداگانه رهاسازی و سپس با غلظت‌های 5/0، 1 و 5/1 درصد روغن ولک و آب (شاهد) روی برگها اسپری و پس از 24 ساعت تعداد حشرات مرده و زنده شمارش شد. نتایج نشان داد که در سطح احتمال 5 درصد اختلاف معنی‌داری بین اثر غلظت‌های مختلف و در تمام مراحل سنی هر دو کفشدوزک وجود دارد. غلظت 5/1 درصد دارای بیشترین مرگ‌ومیر، بهترتیب به‌میزان 11/1±16/92 و 24/1±83/96 درصد در لارو سن اول کفشدوزک‌های C. montrouzieri و C. bipustulatus بود. براساس نتایج و مقایسۀ آن با معیارهای ارزیابی سازمان بین‌المللی مبارزۀ بیولوژیک (IOBC)، درصد مرگ‌ومیر غلظت‌های ١ و 5/0 درصد روغن ولک در اکثر مراحل سنی برای هر دو گونه کفشدوزک در ردۀ دوم گروهبندی اثرات جانبی آفتکشها (با خطر متوسط) قرارگرفتند. | ||

| Predator ladybird, Cryptolaemus montrouzieri and the armored-scale ladybeetle, Chilocorus bipustulatus (L.) are important predators of Diaspididae and Eriococcidae families in Iran. Application of mineral oils are among chemical methods to control mealybugs which are more compatible with the environment and relatively quickly are destroyed in the environment and the risk of secondary pest resistance in regards with these compounds is very low. In this study, the effect of Volk oil® on adult and different larval stages of C. montrouzieri and C. bipustulatus was evaluated on citrus leaves in orchard conditions. Ladybeetles were released and then sprayed with Volk oil at the concentrations of 0.5, 1, 1.5 percent and water (control) was carried out and after 24 hours the number of dead and alive insects were determined.. The results showed that there were significant differences between the effects of different concentrations on life stages of both ladybirds at 5% level. The concentration 1.5% had the highest mortality rate, as 92.16±1.11and 96.83±1.24 percent on the 1st larval stage of C. montrouzieri and C. bipustulatus ladybirds, respectively. Based on the results and compared with the evaluation criteria of the International Organization for Biological Control (IOBC), mortality rate caused by 1 and 0.5% concentrations of Volk oil in most age stages for both predators were placed in the second group of side effect ranking (Moderately Harmful).
