چکیده انگلیسی
In recent years, the use of plant derivatives such as essential oils has been considered as a substitute for chemical pesticides in pest control. Essential oil of Cyperus rotundus L. rhizomes was extracted by hydrodistillation and its compounds were identified by GC/MS. Also, the contact toxicity and repellent activity of essential oil against adults Callosobruchus maculatus F., Oryzaephilus surinamensis L., and Trogoderma granarium Everts were evaluated in the laboratory (27â¯Â±â¯2â¯Â°C, 65â¯Â±â¯5% relative humidity, and dark conditions). The results showed that elemenone (13.59%), α-cyperone (13.14%), and caryophyllene oxide (13.03%) were the major constituents of essential oil. The values of LC50 for C. maculatus, O. surinamensis, and T. granarium in contact toxicity were 0.36, 0.51, and 0.2â¯Î¼L/cm2, respectively. The repellency percentage of essential oil on O. surinamensis, T. granarium, and C. maculatus was 94%, 94%, and 80% after 2â¯h, and 90%, 92% and 70% after 4â¯h, respectively. According to these results, essential oil of C. rotundus can be used as a suitable substitute for chemical pesticides to protect the stored products against pests.
