Seasonal and nocturnal flight activity of Spodoptera frugiperda Males (Lepidoptera: Noctuidae) monitored by pheromone traps in the coast of Chiapas, Mexico
Florida Entomologist 87 (4), 496-503
Abstract: We determined seasonal and nocturnal flight activity of Spodoptera frugiperda (J. E. Smith) males with traps baited with pheromone in the coast of Chiapas, Mexico. A total of 3015, 3065, and 838 males were captured in 2000, 2001, and 2002, respectively. Pheromone trap catches decreased approximately 72% during 2002 with respect to 2000 and 2001. One of five experimental sites caught 90% of the total captured. The pattern of trap captures was quite variable among years and sites. In general, the flight activity of S. frugiperda males was seasonal, with two distinctive peaks in trap captures during the year. Males were caught during all hours of scotophase, however, most males were captured during the first 7 h. Highest peak capture was between 1900-2000 h. Trap captures were positively correlated with wind speed and temperature, and negatively correlated with relative humidity. Significantly more males were captured at wind speeds of 100-200 and >200 m/min than at wind speeds of 0-100 m/min.
