The present paper is an overview of the persistence of Chlorfluazuron (Atabron 5%), Lufenuron (Match 5%), Flufenoxuron (Cascade 10%) and Hexaflumuron (Consult 10%) under certain environmental factors, the present study was investigated the stability of active ingredients under accelerated storage through 54^oC + 2, 45^oC + 2, 40° + 2, 35°C + 2 , 30°C + 2   for 14 days, 6 weeks, 8weeks, 12 week , 18 week respectively, also, including some consideration for developing studies physical properties for each unsorted and stored benzoyl urea formulation. Generally the chemical properties of the previous pesticides were estimated by HPLC. The results obtained could be summarized as follow: Data showed that the  degradation of active ingredient not exceeds the international limit (acceptable limit) under pervious storage temperature. On the other hand, data showed that Lufenuron more persistence and Chlorfluazuron high degradable under temperature degrees (25°C, 35°C and 45°C). The different physical properties for unsorted and stored tested pesticides are in all allowed limits according to WHO and FAO.
