Figure 3
Steinernema feltiae and Steinernema carpocapsae IJs dispersal in the absence of pheromones from insect host cadavers. (A) Dispersal assay. IJs are placed in the center of a 6 cm diameter agar plate. The dashed lines represent a 1.3 cm diameter circle that marks the dispersal boundary. IJs that move outside the boundary are considered dispersed. Quiescent period is the time it takes IJs to resume normal activity and move toward the dashed lines. (B) S. feltiae IJ dispersal. The mean ± s.e.m. of 3 replications is presented. *Indicates statistically significant difference from Day 0 among means. Linear regression analysis. R2 = 0.93. (C) S. carpocapsae IJ quiescence. It is varaible with time and temperature. (D) S. carpocapsae IJ dispersal after quiescence.
