Aphidicidial activity of seven essential oils against the cabbage aphid, Brevicoryne brassicae L. (Hemiptera: Aphididae).

Abstract

The aphidicidial activities of seven essential oils were investigated against Brevicoryne brassicae (Hemiptera: Aphididae) under laboratory conditions. Applications of each tested essential oil significantly reduced the reproduction potential of the cabbage aphid and resulted in higher mortality. Quantity of applied essential oils also had an important effect on daily fecundity. In general, these seven applied essential oils can be considered as an important aphidicide to control aphid population, particularly J. excelsa, J. oxycedrus, L. nobilis and F. vulgare.
