A field trials were conducted to evaluate the efficiency of the new products of Radiant 12% SC, Spintor 24% SC and Runner 24% SC, alone or as mixture with mineral oil in comparable with conventional insecticide dursban 48% EC, against the egg masses of cotton leafworm Spodoptera littoralis and some predators at Qalubia and Sharkia Governorates during 2005 and 2006 cotton seasons, respectively. Generally from the results of the two seasons, radiant, spintor and runner alone recorded moderate percent mortalities for S. littoralis egg masses, and when mineral oil was added to radiant and spintor compounds their activities increased and resulted in egg masses percentages equal or in par with that obtained with the conventional insecticide dursban. Increasing the concentrations of radiant and spintor induced a gradual increase in their activities against egg masses of cotton leafworm. Generally, the all tested compounds and their mixtures with mineral oil recorded low reduction percentages in predators population ranging  between 19.13 and 37.20 % which recorded for radiant at 10 ml/feddan concentration and spintor 35 ml + mineral oil 1000 ml/feddan, respectively, as compared with 77.29 % resulted with conventional insecticide.
