Abstract

The pheromone trap catch of Helicoverpa armigera was investigated during the period of April-December in Habikino (1996-2007 and 2010-11), Kishiwada (2000-11) and Yao (2000-11) in Osaka prefecture. The male moths were caught from early April to late December and the peak catches were detected during the period of September-October. In the past 4 years, 2008-11, more moths have been caught than during the period of 1996-2007.
