Abstract:

An experiment was carried out during rabi 2011 and summer 2012 in Large Plot Completely Randomized Design with four treatments viz., pheromone traps @ 30, 40, 50 /ha  and control withten replications to standardize the requirement of pheromone traps for mass trapping of Helicoverpa armigera (Hubner) Hardwick infesting tomato [Solanum lycopersicum Linnaeus] crop. The results revealed that the highest moth catches were recorded (9630 moths /ha) during first year, while 9405moths /ha were recorded during second year with an average of 9518 /ha during two consecutive years. The treatment of 50 traps /ha recorded significantly lowest population of eggs (0.78 /10 twigs), lowest larval population (1.32 /10 twigs) resulting in lowest fruit damage (3.71%).
