| Abstract | ||
| A study conducted in Tech. Faculty/Musiaib during 2012-2013 for isolation and identification of collateral fungi from Apricot leaf ,white fly ,dubas palm and the predators that are feeding on each of the mentioned pests well as detection of diseases of some fungi isolated from nymphs, pupa and adults of these insects . fungi Penicilium janczwski, Aspergillus terreus, A. parasticus and Clado sporiumcladosporiods are isolated from Apricot aphid and the fungi A. sterreus , A. parasticus and Drechslraaust traliensisare isolated from white fly while the fungi A. parasticus, A. pesudodeflictus, Trichoderma auroviride, Drechslraaus traliensisare isolated from dubas palm . The results showed that the fungi Penicilium janczwski gave the highest percent of appearance from apricaot aphides 50% while the fungus A. parasticus, gave the least percentage 22%. Also the fungs A. terreus recored the highest percentage of appearance 48% with white fly while the fungs A. terreus wheras and Cladosporium cladosporiodsleast gave the percentage 26% . In addition the fungus Trichoderma auroviride gave the highest percentage of appearance with date palm dubas 62%,where the fungus Drechslraaus traliensis gave the least percentage 30% . The fungus Penicilium janczwskii suspension in a conc. 13.5×102 was more effected on nymphs and the adults of apricot aphids with killing percentage of 45.00 and 42.99% for the two phases respectively after 5 days of the treatment ,while the suspension of A. terreus at a conc. of 18.9×102 gave the highest killing percentage for nymphs and adults of White fly 37.17% and 37.23% respectively after 5 days of the treatment .On the other hand Trichoderma auroviride gave higher killing percentage 23.39% and 35.29% both for nymphs and adults of date palm Dubas respectively after 5 days of treatment . Neither of the suspension isolated from Homoptera or the preditors of Coccinilla (7 point and 11 points) showed any effect on larvies and adults of the Coccinilla . | ||
