Fumigant toxicity of essential oils from citrus reticulate Blanco fruit peels against Rhyzopertha dominica F. (Col.: Bostrichidae)
Journal Title: Scientia Agriculturae - Year 2013, Vol 1, Issue 3
Abstract
The insecticidal activity of a large number of essential oils and other plant extracts has been assessed against several major agricultural pests. This study was conducted to determine the insecticidal activity of essential oils fromcitrus reticulate Blanco (Rutaceae) against adults of theRhyzoperta dominica.The exposure times were 24 and 48 hours in all experiments. Experiments were performed in completely randomized design with 3 replications. After treatment the samples were held under constant conditions in rearing room at 26±1ºC, 60±5 R.H. in darkness. The results indicated that the mortality of adultsincreased with increased concentration and exposure time.LC50 values were 18.30 and 15.52 and LC95 values were 78.15 and 57.97 μl/l air at 24 and 48 h after exposure of R.dominicaadults respectively. Therefore, these essential oils were suggested to be used for R.dominicacontrol in stores.
