13.5 Mortality at Each Stage
of the Life Cycle of C. capitata
and Overall Mortality

on puparium formation as well as on the
overall mortality. The effect of such extracts
on insect mortality was also recorded as
emergence or non-emergence of the adult
stage. Results are shown in Table 13.1
(Broussalis et al ., 2010).

The effect of the CH 2 Cl 2 and 50% EtOH
extracts at 1000 and 100 ppm were evaluated
