Abstract
The efficacy of Neem Azal®-T/S (1% Azadirachtin A) was field-evaluated during
2002 in olive tree orchards. The research was carried out in Idlib, northwest of
Syria. Two concentrations (0.3% and 0.5%) of Neem Azal®-T/S were used against
Euphyllura olivin Costa (Homoptera: Psyllidae) and Prays oleellus
(Lepidoptera: Yponomeutidae), as well as one concentration (0.15%) of Roger®
(40% Dimethoate), at two date of applications. Results showed that Neem
Azal®-T/S at a rate of 0.5% was highly effective on larvae of P. oleellus
and on nymphs of E. olivin, and is the most appropriate insecticide to be
recommended for integrated pest management of both insects. Although Dimethoate
effectively control led P. oleellus larvae, it was harmful to its
parasitoids. Using natural pesticides, such as Azadirachtin A, was beneficial in
producing healthy food with no chemical residues, cost-effective, preserved the
natural enemies of insect pests, and less polluting to the environment.
