Abstract:The age of susceptibility of cotton bolls to attack by Pectinophora gossypiella (Saunders) was determined under field conditions in Imperial Valley, Calif. Bolls of all ages were successfully attacked by 1st to 3rd instars. However, bolls most susceptible to attack were of age 14–21 days. Boll age was correlated with size and moisture content, and a simple means is suggested for determining boll age for field sampling.
