Abstract
The oviposition behavior of Callosobruchus maculates F. consists of three phases: patrolling of seed surfaces, preparation of the chosen oviposition site with glue, and egg deposition. An egg-marking pheromone is deposited with the egg. Disturbance of the oviposition sequence by courting males is likely to occur near its onset, but is less likely in later phases. This suggests that females nearing emission of the egg are programmed to complete the process. Alternate hypotheses accounting for the evolution of this behavior are discussed.Keywords
