Pink Bollworm Spring Emergence Related to Weather Parameters

Carol J. Adams, C.A. Beasley, and T.J. Henneberry


 
ABSTRACT

The large variability from day to day in numbers of spring emerging pink bollworm moths caught in gossyplure baited delta traps and in emergence cages was highly correlated with weather variables. The high correlations found may be measures of moth emergence, activity levels, and/or trapability. Moth catches were positively related to temperature and variability of wind direction and were negatively related to wind speed. Other parameters of weather also impacted trap and cage catches as shown by the multiple regression analyses. Traps were situated in a fallow field, in fields planted to cotton and along roadsides throughout the Palo Verde Valley, California. Bolls were collected throughout the fall and placed in cages for monitoring of spring emergence. Data were collected over several years.
