Figure 1. Persistence of B. bassiana spores on foliage (open circles, colony forming units
per sq leaf cm 2 ) and soil (open diamonds, colony forming units per dry soil gram).
Daily precipitation is shown (bars, millimeters per day). 96
Figure 2. Principal response curve (PRC) for the predator guild from pitfall trapping,
indicating the effects of a single spraying of B. bassiana (squares) or lambdacyhalothrin
(triangles), compared with the control (circles). Values deviating from the
reference value of 0 indicate treatments effects. Weights (right) indicate the affinity of
the taxon with the PRC trend. 97
Figure 3. Principal response curve (PRC) for the predator guild from soil cores, indicating
the effects of a single spraying of B. bassiana (open bars) or lambda-cyhalothrin (grey
bars). Weights (right) indicate the affinity of the taxon with the PRC trend. 98
Figure 4. Principal response curve (PRC) for the herbivore guild, indicating the effects of a
single spraying of B. bassiana (open bars) or lambda-cyhalothrin (grey bars). Weights
(right) indicate the affinity of the taxon with the PRC trend. 99
Figure 5. Principal response curve (PRC) for the decomposer guild, indicating the effects of
a single spraying of B. bassiana (open bars) or lambda-cyhalothrin (grey bars).
Weights (right) indicate the affinity of the taxon with the PRC trend. 100
