摘要:

Emergence of boll weevils from overwintering habitat was variable among years and among fields within a year. Use of heat units to predict emergence was no more accurate than use of Julian dates. Emergence curves with confidence limits were constructed to show the variability in emergence that could be expected at any time during the emergence period, and to predict future emergence.
