| Abstract |
Oil crops peanut (Arachis hypogasae) and Sesame (Sesamum indicum L.) varieties were evaluated for their resistance to the red spider mite Tetranychus urticae Koch infestation, with influence of sowing date and fertilizer sources on population abundance of mites on both crops. Peanut crop: obtained results revealed that balady variety expressed highly susceptible, while Giza 4 variety was resistant and Giza 5 was intermediate one. Sesame crop: Data showed that Giza 25 variety was susceptible to spider mite infestation more than Giza 32, In both of oil crops peanut and sesame the rate of infestation is markedly influenced by planting date and fertilizer sources whereas obtained results indicated that plants of the both crops seeded later (30th of May) suffered heavier infestation than that seeded earlier (30th of April). Adding nitrogen fertilizer alone had considerable role in level infestation of spider mites, followed by mixture of N and K while the opposite took place with adding potassium, alone.
