The Synergistic Effect of Surfactants and Plant Oils on the Effectiveness of Levo to Control the Fourth Phase Larvae of the Great Wax Moth Galleria Mellonella L. (Lepidoptera: Pyralidae)

Abstract

The laboratory study aimed to know effect three surfactants (Inex-A, Stickon, Wetfix) and plant oils Includes Bitter apple oil Citrullus colocynthis, and Rosemary oil Rosmarinus officinalis on effectiveness five concentrations ppm ((30,40,50,60,70) for commercial pesticide plant origin Levo2.4SL (Oxymatrine) on fourth phase larvae to Great Wax Moth G.mellonella. The results showed that were significant differences in mortality percentage to fourth phase larvae of Great Wax Moth worm by the effects Levo pesticide on larvae, as (Levo + rosemary oil) treatment excelled in achieving highest larval mortality percentage 84%, followed by (Levo + bitter apple oil) treatment, with an average mortality percentage was 72%. while mortality percentage in (Steckon + Levo) and (wetfix + Levo) treatments was 70, 67.33, respectively. Levo pesticide efficacy decreased in (Inex + Levo) treatment to 38% compared with mortality percentage in before addition treatment to Levo pesticide, which amounted to 63.33%.
