| Abstract | ||
| The following fungi Alternaria alternata, A.pluriseptata, Aspergillus terreus, Eurotium eurotiorum, Stachybotrys atra, Ulocladium chartarum were isolated from the nymphal and adult instars of two-spotted spider mite. Fungal inoculum of 106 spores/ml revealed a rate of mortality 45.9, 42.03% on the egg mites for both S.atra, Trichoderma harzianum, respectively. The spore suspension of A.terreus on nymphal instars showed rate of mortality 63.03% after 72 hourse of treatment. It was also shown that the spore suspension of A.terreus, and T.harzianum revealed highest rate of adult instars mortality 65.5, 62.9% respectively. The effect of culture filterate of A.terreus and A.alternata on egg instars mortality was 55.9, 53.1% respectively. An increase of fungal culture filtrate in the media was showed an increase in the rate of mortality of nyphal instars. Apparently that the culture filtrate of A.alternata ; A.pluriseptata and A.terrens revealed mortality rates of 46.2, 45.5, 44.4% respectively. The rate of mortality in the culture filterate on adult instars 45.8, 45.01% by A.terreus and A.alternata respectively. | ||
