چکیده
In this study, the efficiency of essential oils from asafoetida, Ferula assa foetida L.,geranium, Pelargonium hortorum L.H. Bailey and walnut leaves, Juglans regia F. was investigated on nutritional indices of Rhyzopertha dominica (F.) adults. Wheat grains were treated with different concentrations of the oils. The nutritional indices: relative growth rate (RGR), relative consumption rate (RCR), efficiency of conversion of ingested food (ECI) and feeding deterrence index (FDI) were measured at ۲۸ ± ۲ °C, ۶۵ ± ۵% R. H. in continuous darkness. RGR, RCR and ECI deceased as the concentration level was increased. While, FDI percent increased significantly as the concentration level increased. Asafoetida oil had the most efficiency on nutritional indices and ۲۸.۶۱ ppm of the oil was enough to decrease RGR, RCR and ECI% to ۰.۰۳۲ mg/mg/day, ۰.۴۴۴ mg/mg/day and ۶.۹۹۴%, respectively. FDI percent of adults exposed to ۶.۵ ppm of asafoetida oil was ۱۳.۳۱% which increased upto ۶۴.۶۲% at the concentration of ۲۸.۶۱ ppm. In the second experiment, the effect of tested essential oils was evaluated on F۱ progeny reduction of R. dominica. Walnut and asafoetida leaves essential oils significantly suppressed progeny production by (۵۹.۹۲%) and (۵۳.۲%) respectively.کلیدواژه ها
