To evaluate the effect of insecticides on the life table parameters
of O. insidiosus, the insects that adulthood were paired. Only treatments
that allowed the formation of five or more pairs were
assessed, these treatments were considered to be harmless to O.
insidiosus. Each couple was placed in a 5-cm-diameter Petri dish
containing a B. pilosa stem as oviposition substrate and moistened
cotton wicks. The B. pilosa stems were changed daily and couples
were fed eggs of A. kuehniella every 48 h. The number of eggs laid
and the survival of adults were assessed daily.
