Cotton mealybugs, Phenacoccus solenopsis, (Tinsley) Hemiptera: Pseudococcidae, caused major loss in economic crops at over the world. This study was conducted to test and evaluate effect of some insecticide classes on the cotton mealybugs P. solenopsis, in the field condition on Jews mallow, Corchorus olitorius, L., and okra, Abelmoschus esculentus, L., on Nage Hamade, Egypt. This treatment was Actellic 50 %EC , KZ oil 95% EC (mineral oil), Actellic 50 %EC + KZ oil , Beauveria bassiana (Biothiana), Biothiana + KZ oil (0,75L/ 100L), Biothiana+ KZ oil  (0,375L/ 100L), Metarhizium anisopliae  (Biometa), Biometa+ KZ oil (0,75L/ 100L) and Biometa+ KZ oil  (0,375L/ 100L). All treatment had high effective on nymph than adult. This date showed that high effect was recorded by Actellic 50 %EC + KZ oil on both crop. Biothiana had high effect than Biometa in case used solitary or mixed with KZ oil. Statically analysis shows that the high effect was recorded by Actellic 50 %EC + KZ oil followed by Actellic 50 %EC , bioinsecticides mixed with KZ oil, bioinsecticides solitary  and finally KZ oil only.
