Efficiency of some alternative insecticiceds on the white peach scale, Pseudaulacaspis pentagona (HEMIPTERA: DIASPIDIDAE) [electronic resource].

Includes reference.

The present work was conducted to evaluate the efficiency of some altemative insecticides on the nymph and adult female populations of P. pentagona under laboratory and field conditions. Two groups of altemative insecticides were evaluated, these groups were Mineral oils (Misrona oil 85% mayonnaise & Alboleum oil 80% mayonnaise were used at rate of 2.5 %.) and Neem extracts (Neemix 4.5 % EC & Trilogy 90 % EC were used at rate of 1% and 1.5 %, respectively). One Organophosphorus insecticide (Fenitrolhion 50 % EC at rate of 0.15%) was used as control measure for the two altenative groups. Laboratory bioassays of the tested alternative groups were carried out under laboratory conditions. by dipping the infested branches in the solution of each tested compound where the field evaluations were carried out in peach orchard at Qalubiya Governorate by spraying the tested alternative compounds with motor sprayer (Kobota).
