and early winter seasons of 1963, 1964, and 1965 showed that ovipositlon prior to 

 diapause was negligible. However, diapausing females about 30 days old often 

 became reproductive. Observations on the general behavior of the females are 

 given.

9 pp. 

 Studies of overwintered boll veevils in the trap crop plantings of cotton showed 

 that time of greatest infestations was variable with peak numbers occurring after 

 mid-June more than 50 percent of the time. Results obtained from pheromone traps 

 were similar to data recorded in the trao plots. Results of the 9 years of experi- 

 mentation show the difficulty of scheduling automatic Insecticide programs for 

 overwi'Atered boll weevils that would be highly reliable in affording good control 

 every season. Data on the summer and fall migration of the boll weevil to the 

 trap plantings and pheromone traps showed that major migration does not occur 

 until late August or about the time of F^ generation. However, in the 1967 

 season, some movement of the insect was noted throughout the summer prior to the 

 time of the large migrating F . Summer and late summer r.igration occurred at a 

 time when most of the cotton in the test areg^was being treated with scheduled 

 app^^XLations of insecticides.
