Abstract
The use of oils obtained from plants has been an alternative to pest management, because they are selective, biodegradable and have little effect on non-target organisms. The objective of this work was to evaluate the storage effect on jatropha oil ( Jatropha curcas L), for a period of 150 days, and its potential on the cabbage aphis ( Brevicoryne brassicae (L.) (Hemiptera: Aphididae)). Mortality was evaluated in relation to the time after application. The solution was sprayed onto discs of kale leaves containing aphids, with the help of Potter's Tower. Seven oil concentrations were tested, with 10 replicates per treatment. There was no statistical difference between the storage time and the different concentrations of J. curcas on B. brassicae mortality, all treatments being efficient in the management of cabbage aphis.
