Figure 1:
Percentage of mortality of different stages of Maconellicoccus hirsutus according to different concentrations of Heterorhabditis amazonensis; dark gray bars = females; light gray bars = second and third nymphal stages; white bars = crawlers (first nymphal stage). Bars with the same letters do not differ significantly among treatments per developmental stage (means ± sem).
Figure 2:
Percent invasion by Heterorhabditis amazonensis of different stages of Maconellicoccus hirsutus at different concentrations. Dark gray bars = females; light gray bars = second and third nymphal stages; white bars = crawlers (first nymphal stage). Bars with the same letters do not differ significantly among treatments per developmental stage (means ± sem).
Figure 3:
Probability of mortality of different stages of Maconellicoccus hirsutus according to the number of Heterorhabditis amazonensis (probit). A = females, B = second and third instars, C = crawlers. Black lines represent the mean of the probability. Gray lines represent confidence intervals (95%).
Median number of Heterorhabditis amazonensis capable to invade different developmental stages of Maconellicoccus hirsutus.
