Department of Veterinary Parasitology, Veterinary College and Research Institute, Namakkal. Tamil Nadu

Abstract

In vitro trials were carried out to determine the efcacy of plywood coated with spores of entomopathogenic fungi (bait) against adult ies. One hundred fresh pupae each were placed into three in vitro trial chambers (A, B and C) made of ne mesh with zip lock system and upon  y emergence, plywood (5 x 3”) smeared with mixture of fungal spores with honey and castor oil separately at the concentration of (15 x 107) were placed in the chamber A and B respectively. The bread slices soaked in milk were placed in the control chamber(C). The fungal infected ies showed the behavioural changes after 4th day of infection, which included reduction in feeding, resting at hot places, grooming and wobbling prior to death. Mortality was recorded from 5th day onwards. Castor oil and honey based baits caused > 90 per cent mortality in adult ies.
