Relative to the other four species, a greater number of S. carpocapsae infective juveniles entered the R. indifferens larvae, and 4th-stage juveniles and adults were recorded in 31 of 40 pupae. Thirteen puparia each contained hundreds of S. carpocapsae infective juve-niles. In 1 pupa, reproduction occurred, as evidenced by the presence of 1st- and 2nd-stage juveniles.
Even though H. bacteriophora killed a greater per-centage of pupae than S. feltiae, the reproductive potentials of the two species within the puparia were fairly equal. Seven puparia were infected with H. bacteriophora adults and eight puparia with S. feltiae adults. Seven puparia of each species were infected with hundreds of infective juveniles. A greater percent-age (50%) of pupae were dead but not infected with S. feltiae. Higher mortality of noninfected pupae may have been due to an interruption of metamorphosis.
