In stored wheat products, Rhyzopertha dominica (F) (Coleoptera: Bostrichidae) is an important pest that results in significant economic losses. Insect physiology and behavior can be affected by bioactive compounds extracted from plant wastes, which are important tools for developing bioincesticides. The purpose of this study is to develop an insecticidal packaging film based on pectin and essential oil (EO) extracted from Citrus aurantium (L., 1753) fruit peels.The encapsulation efficiency (EE) and cumulative release (CR) of C. aurantium EO into pectin film were determined. Further, Film packaging was tested against Rhyzopertha dominica adults reared on Karim and Khiar durum wheat (Tritichum durum Desf.) varieties. The fumigant toxicity was assessed after 10, 20, 30 and 40 days of storage. Moreover, emergence inhibition of R. dominica adults was determined. In addition, germination rate, weight loss and grain damage were examined.Results revealed that the lethal concentration that killed 50 % of the exposed adults developed into karim and khiar varieties were 278.45 and 688.79 µL/L air, respectively. Moreover, high encapsulation efficiency of C. aurantium essential oil into pectin film with an EE = 80.6 %. Moreover, pectin: EO film achieved complete (100 %) mortality and emergence inhibition of R. dominica adults for all storage periods. Also, pectin: EO film represent the better treatment which preserve the quality and quantity of wheat grains as well as grain damage, weight loss and germination rate. To concludepectin- C. aurantium EO film showed a significant fumigant effect against R. dominica adults and the emergence of their descendants after different storage periods and could be recommended as an active ingredient for a natural packaging against stored product insects.
