Abstract

The southern coast of the Caspian sea is an increasingly urgent problem, because of pesticide applications is increasing. This research is based on management of pesticide that is a component of integrated pest management (IPM), which seeks to minimize pesticide use through application of alternative tactics. The response of Phyllocoptruta oleivora (Ashmead) to different percent of mineral oil and determination of LC90 & LC50 using bio – assay technique was tested.
The treatment applied in three different techniques including: submerging fruit in the treatment, using spray tower and backpack (bp) sprayer. Probit analysis has been done using P/PROBAN computer programme. Laboratory evaluation of mineral oil indicated that in very low concentration of mineral oil the mortality were very high, using submerging technique. The LC90 & LC50 were calculated 0.37 & 0.74 %, respectively, using (bp) sprayer .
