Abstract
According to Ministry of Agriculture Protocol for natural materials,
the successful material should gave initial effect ≥ 70% and residual
effect ≥ 40% reduction. This condition was fulfilled at 1.5%
concentration of all plant oils tested alone or as mixtures used against
Thrips tabaci and Tetranychus urticae infestations on bean plants. Also,
both pests were more susceptible to the oil mixtures of (fixed + volatile)
than plant oils alone at 1.5% such as (cottonseed + lemongrass), (linseed
+ citronella) and (castor + lemongrass) for adults of T. tabaci and T.
urticae. The mixtures showed higher efficiency in general. Concerning
the residual effect, onion oil alone and the mixture of (cottonseed +
lemongrass) oil at 1.5% caused 100% reduction in adults of both pests.
Also, the same reduction occurred by the use of mixtures of (linseed +
lemongrass) oil against T.tabaci and (castor + chamomile) oil against
T.urticae .
