Abstract

The number of male tobacco budworm, Heliothis virescens (Fabricius), trapped on a daily basis in pheromone traps in individual cotton fields was compared to male and female adult densities measured by nocturnal field sampling. The decline of trap efficiency with increasing female density was demonstrated. A simple relationship for estimating H. virescens male density from the numbers trapped was derived as P♂ = (E2/13)2, where P♂ is density and E2 is the two-day exponential average of number trapped. The standard error for the regression translates to an accuracy ratio of 2:1. The results compare favourably with previous research using mark-release-recapture methodology. Application of the formula is discussed.
