SUMMARY
The distribution studies of Cenopalpus pulcher and Qrthatydes californicus on different parts of apple trees in Gharbia Governorate during 2003 season, showed that more than 80% of the mite population occurred on the new terminal and mature leaves from the outer parts (around the tree), while less than 20% (near the trunk). Two spraying methods were conducted. In the oriented spraying method only the outer circumference part of apple tree was sprayed with Super Misrona oil + Sulphur, Biofly and Flufenoxuron compared with Kelthane-S. On old outer leaves, Super Misrona oil + Sulphur and Flufenoxuron gave 87 and 89% average reduction against the tenuipalpid mite; while Biofly gave 68%. Also, new terminal leave, Super Misrona oil + Sulphur and Flufenoxuron gave 86 and 82%; while Biofly gave 63%. On the other hand, the indirect spraying liquid "drift" gave some reduction on old outer leaves (near the trunk), Super Misrona oil + Sulphur and Flufenoxuron gave 74 and 76%; while Biofly gave 53%. Kelthane-S was highly effective against the tenuipalpid mite as, on old outer leaves it gave 97%; while gave 93% on new terminal leaves. On old outer leaves, Super Misrona oil + Sulphur was highly toxic against O. californicus (100% kill); Flufenoxuron and Biofly 90 and 84%. On new terminal leaves, Super Misrona oil + Sulphur gave highly toxicity against the predator (100% kill); Flufenoxuron and Biofly 91 and 80%. Also, Kelthane-S was highly effective (100% kill). In the whole tree spraying trail gave similar results to those obtained from the oriented trail (outer circumference spraying). The oriented spraying of circumference part was more economic (about 3 times), and safer to the environment than spraying the whole tree. The whole tree spraying was expensive (estimated cost was 410 LF). On the other hand, oriented spraying program showed the lowest cost (i.e. estimated as 145 LE).
