| Abstract | ||
| A laboratory study was carried out to evaluate the effect of the naturally derived miticide Abamectin, dicofol and three local mineral oils (Super Shokrona, Shokrona and Star oil ) on different developmental stages of the two phytophagous mite species, Eutetranychus orientalis (klein) and Brevipalpus californicus, (Banks) and the predatory mite, Amblyseius scutalis ( Athias Henriot) ( = Amblyseius gossipi El -Badry). Abamectin and dicofoi were the most effective compounds against all the developmental stages of the two phytophagous mites while eggs and adults of the predatory mite were less susceptible to the same compounds. Eggs of E.orientalis were more susceptible to the three local mineral oils than eggs of B. califomicus. Super - Shokrona was more effective on the two phytophagous mites than Star and Shokrona oils . The three local mineral oils were less toxic on eggs of the predatory mite, A. scutalis. Immature stages of B. califomicus seemed to be more susceptible to the mineral oils than those of E. orientalis . The three local mineral oils were found to be less toxic on adult females of the predatory mite than on those of the two phytophagous ones. | ||
