| Abstract: | The white peach scale Pseudaulacaspis pentagona Targioni during the middle of first instar nymphs could be controlled with dilution (1:1000-1500, W.P.. water) of 25% buprofezin W. P. spraying one time in the peach garden. Its effect for controlling its instar nymphs reached 92.2 % -96.3% and persisted for three weeks. However toxic effect was slower than that of conventional insecticides. |
