Abstract :
The melon aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. To control the pest population, research on the use of the environmental and plant-based compounds has increased in recent decades. Essential oils due to volatility and very short-term persistence in the environment, as biocompatible pesticides can be considered as one of the best alternatives to chemical pesticides in aphids control. In the current study, chemical composition and fumigant toxicity of the essential oil from Peppermint, Mentha pipertia L. (Lamiaceae) was evaluated against the melon aphid, A. gossypii in the laboratory conditions under 25±2°C, 60±5 RH and 16L:8D photoperiods. The essential oil was obtained by hydrodistillation method, using a modified Clevenger-type apparatus. Mortality was evaluated at different concentrations that rang from 0.1 to 0.9 μL/L air, and with three replications at the interim of 24 hours. Also, nymph production deterrent effect of the oil at sublethal concentration was studied against parthenogenesis form of aphid. Results indicated that essential oil of M. pipertia is toxic to A. gossypii. The major components in the oil were Menthol (30.09), Menthone (20.38), 1,8- Cineole (9.09), Cyclohexanol, 5-methyl-2-(1methylethyl)- ĮȕĮ (8.72), 2-Cyclohexen-1one, 2-methyl-5- (6.63) and Carane, cis (4.53). Probit analysis showed that the LC50 values for nymphs and adults of A. gossypii were 0.059 and 0.0081 μl. L-1 air, respectively. Also, the degree of nymph production deterrent effect was calculated for essential oil of M. pipertia as 48.51 ± 5.51. The overall results showed that the Peppermint essential oil has high potential in controlling the melon aphid especially in protected areas such as greenhouses.
