EFFICIENCY OF THREE TYPES OF OILS AGAINST APHIS FABAE AND TETRANYCHUS URTICAE

Abstract
Refined paraffinic oil, vegetable oil and esterified seed oil emulsified with ethoxylaled fatty alcohol were evaluated in laboratory studies against the faba bean aphid Aphis lobe° Koch and the red mite Tetranythus urticae Scop. The results showed that half-dose 80% EC was the most toxic against the adults of both faba bean aphid and red mite at LC25 , LC50 and LC90 levels. Alpha-z 96.4% EC came next in toxicity and the vegetable oil was the least effective . It is of interest to denote that all candidate oils exhibited 100 % mortality against aphid adults after 24 hours from treatment at the concentrations 200, 100 and 50 ppm. Complete inhibition of egg hatchability of the red mite T. urticae was obtained at 200 and 100 ppm for all oils. Proper mineral oils, esterified seed oils and vegetable oils of consistent quality can contribute in the development of sound integrated pest management programs, since they are environmentally compatible, possess unique modes of action, novel tools for resistance management and reduce impact on beneficial insects.
