Time course for Steinernema carpocapsae IJ population quiescent period and pheromone stimulated dispersal. (A) The IJ quiescence time at 20 °C in the presence and absence of pheromone extracts. (B) Pheromone extracts stimulated percent IJ dispersal in the first 30 min whereas untreated IJs are quiescent at 20 °C. (C) The IJ quiescent period at 15 °C in the presence and absence of pheromone extracts. (D) Pheromone extracts stimulated IJ dispersal in the first 30 min when untreated IJs were quiescent at 15 °C. The mean ± s.e.m. of 4 replications is presented. #Experiment stopped after 24 h. *Significantly different compared to control.
