“…In our studies the percent mycosis and sporulation was higher in the treatments in which the lower concentration of B. bassiana was applied alone against R. dominica compared with other treatments. Similar results were noted by Tefera and Pringle (2003), who found the higher mycosis and sporulation in cadavers of Chilo partellus (Lepidoptera: Pyralidae) at lower dose rates of B. bassiana compared with the highest concentration; this may be attributed to the self-inhibition mechanism at highest dose rates (Garraway and Evans 1984). Likewise, Adane et al (1996) reported maximum sporulation on Sitophilus zeamais (Coleoptera: Curculioniae) by isolate 190-520 of B. bassiana.…”

“…The cadavers were incubated at 25±2 o C, 75% r.h. for 7 days and those showing external white fungal growth were determined under a stereomicroscope. The data for sporulation were determined by mixing mycosed cadavers from each replication in 20 ml distilled water with a drop of Tween-80 in a beaker (Tefera and Pringle 2003). The treatments were replicated independently three times.…”

A laboratory assay was designed to determine the insecticidal efficacy of Beauveria bassiana (Balsamo) Vuillemin (Hyphomycetes: Moniliales) and diatomaceous earth (Diafil 610) against Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae). The fungus B. bassiana was applied at 2.23×10 7 , 2.23× 10 8 and 2.23×10 9 conidia kg −1 of wheat individually as well as mixed with 200 and 400 ppm of Diafil 610. The conditions for the trials were 30±2 o C with 55% r. h. and the counts for mortality were made after 8, 16 and 24 d. All the dead adults were removed after each count and the vials were kept for the next 60 d to assess the emergence of the F 1 generation. The findings from these studies proved that the extended exposure interval and the highest combined dose rate of the entomopathogenic fungus and the diatomaceous earth gave the maximum mortality of the beetles. The emergence of the progeny was also highly suppressed where the maximum dose rate of the synergized treatments was applied. The rate of mycosis and sporulation in the cadavers of R. dominica was maximum where the low dose rates of B. bassiana were applied.

“…Larvae exposed to Cry1Ac and B. bassinia simultaneously Larvae of O. furnacalis, which had entered the third instar within the 24-h period, were dipped into B. bassiana conidia suspension in serial concentrations of 1.8 Â 10 7 , 1.8 Â 10 6 , and 1.8 Â 10 5 conidia ml À1 for approximately 30 s (Tefera and Pringle, 2003a). The larvae were air-dried for 10 min in sterile Petri dishes.…”
