摘要

Survey of entomopathogenic fungus, Verticillium lecanii (Zimm.) Viegas on C. viridis showed that the fungus is the most effective natural mortality factor during the rainy season. Pathogenisity test conducted on green scale infested Coorg mandarin plants was positive. Field trials for the control of this pest were conducted on arabica coffee before the rainy season with seven insecticides and their sub-lethal doses in combination with fungus at 10 x 10~6 spores/ml. A field trial was also conducted onCoorg mandarin. Tests on arabica coffee just before the onset of rainy season indicated that in the orchards where more light interception (4800-23900 lux) was recorded, the fungus alone or in combination with the micro-dosages of insecticides was ineffective, however, monocrotophos (0.05%), quinalphos (0.05%), primiphosmethyl (0.05%) and fenitrothion (0.05%) gave good result. But in orchard with more shade and less light interception (900-14100 lux), sprays of fungus containing 10 x 10~6 spres/ml + 0.005% quinalphos + 0.05% Teepol even before the onset of rainy season in coffee and during rainy season in citrus were highly effective killing 95.58 and 97.50% scales respectively. Methyl parathion (0.005%)+ fungus + Teepol (0.05%), primiphos methyl (0.05%)+ fungus + Teepol (0.05%), fenitrothion (0.05%), primiphos methyl (0.05%) and phenthoate (0.05%) were also effective under these conditions.
