Tyrophagus putrescentiae (Schrank, 1781). fig trees were sprayed five Repellent substances (extract Melia azedarach L., extract Styrax officinalis L., Sulfur powder, micron Sulfur, Summer oil) are sprayed at arrival number of pests on tree to economic threshold 1 pest/ leaf. Average efficacy on nymphs were (93.6, 91.1, 89.5, 82.8, 60.1%), and on adults were (91.2, 89.2, 83.8, 74.3, 57.2%) respectively. M. azedarach extract gave the highest efficient in death and repellent the pest compared with other repellent substances, then followed with S. officinalis extract, while Summer oil was the least efficient. The results of statistical analysis appeared that their effects were significant between treatments (M. azedarach and S. officinalis) and other treatments at level 5%. It may be possible to use M. azedarach in an integrated pest management (IPM) as alternatives to traditional insecticides efficient and healthy on the environment.
