Abstract
The carob moth, Ectomyelois ceratoniae is one of the main pests that attack storing crops. This polyphagous species attacks several other stored host crops such as pomegranate, almond and pistachio. In this study, the fumigant efficacy of Eucalyptus globulus and Artemisia cina essential oils is tested on the Carob Moth E. ceratoniae. After collecting infested pomegranate and rearing insects in laboratory conditions of 27 ±2 C°,16:8 (l: D) and 60 ±5% relative humidity, the efficacy of oils was evaluated on the insects. Results show that the toxicity of essential oils on the eggs (LC 50, LT 50 values) was not significantly different. The fumigant toxicity of E. globulus (LC50 = 5.92μl/l air) was greater than A. cina (LC50 = 12.95 μl/l air). And lethal time values (LT50) were (10.47 h) and (60.27 h), respectively. According to this study it is possible to propose essential oil as alternative pesticides in pest controlling programs
