| Abstract |
This study was carried out to evaluate the efficacy of two natural bio-pesticides against the two- spotted spider mite, Tetranychus arabicus that is considered one of the major mite pests attacking apple trees in Egypt. It causes series damage for leaves, affecting on the productivity of apple trees. The first bio-acaricide is Challenger 36% SC that is produced from fermentation culture of the microorganism, Streptomyces fummanus. The second is GC- Mite 20% EC which is produced from garlic extract and various essential oils (botanical components). The two former compounds were sprayed against the all stages of T. arabicus on apple trees with concentration 40 cc and 1 liter per 100 L. of water, respectively. They gave reduction in the population density of the mite pest averaged 92.60 and 83.07 %, respectively. Also, the same bio-acarides produced slight reduction on the dominant predatory mite Euseius scutalis averaged 28.28, 20.54 %, respectively. From the obtained results concluded that, it could be these bioacaricides can be used successfully against the mite pest with slightly effect on the predatory mite. Thereby, and can be used in the Integrated Pest Management of this mite pest.
