“…It is important to develop alternative strategies such as entomopathogenic fungi to control P. xylostella populations, which will result in a reduction in the use of synthetic insecticides. Entomopathogenic fungal agents such as Beauveria bassiana (Balsamo) Vuellemin, Isaria (Paecilomyces) fumosoroseus (Wise) Brown and Smith and Metarhizium anisopliae (Metschnikoff) Sorokin have the potential to infect and kill P. xylostella . Among these fungal pathogens, the I. fumosorosea SCAU‐IFCF01 strain used in this study has demonstrated high effectiveness against P. xylostella , the first report of such rapid insecticidal activity against P. xylostella .…”

“…As the resistance of P. xylostella to chemical insecticides and B. thuringiensis toxins highlights a need for alternative tactics, an interest in incorporation of fungal biocontrol agents into its management systems has been increasing. To date, a few fungal agents including Beauveria bassiana (Balsamo) Vuellemin,10–13 Metarhizium anisopliae (Metschnikoff) Sorokin14 and Paecilomyces fumosoroseus (Wize) Brown and Smith15, 16 have been under investigation. Studies have demonstrated the potential for application of these fungal agents against the pest species and B. bassiana has proved the most promising 14…”

Six bioassays were conducted to evaluate the interaction between Beauveria bassiana SG8702 and a nereistoxin analogue insecticide, diammonium S,S'-(2-dimethylaminotrimethylene)di(thiosulfate), which is highly compatible with the fungal biocontrol agent against diamondback moth Plutella xylostella (L.). Second-instar larvae were exposed to sprays of B. bassiana alone (assay 1) at concentrations of 21-38, 157-232 and 822-1133 conidia mm(-2) or together with the insecticide at the low application rates of 5, 10, 25, 50 and 100 microg AI ml(-1) (assays 2-6), and then maintained at 25 degrees C and 12:12 h light:dark photoperiod for daily monitoring of mortality for 8 days. Based on the modelling of the resultant time-concentration-mortality data sets, the fungal agent was highly virulent to P. xylostella with an LC50 decreasing from 269 conidia mm(-2) on day 4 to 107 on day 8. Lower lethal concentrations or shorter median lethal times resulted from fungal sprays including the tested chemical rates; the latter never caused higher mortalities than the fungal treatments alone. The fungal action over 3-7 days after spray was significantly enhanced by including in the fungal sprays the chemical at rates of > or =25 microg ml(-1) for 2.6- to 1756-fold reduction of LC50 values, > or =50 microg ml(-1) for 4- to 274-fold reduction of LC70 values and 100 microg ml(-1) for 9- to 33-fold reduction of LC90 values respectively. These rates were equivalent to 5-20% of the chemical rate labelled for field application. The fungal and chemical interaction outlined above highlights the feasibility of combined formulation or application of B. bassiana and the chemical insecticide for P. xylostella control.

-Chemical insecticides are broadly applied to control diamondback moth, Plutella xylostella (L.). Diamondback moth is a major pest of cruciferous worldwide, and resistance of this pest to insecticide has been often reported. Thus, this research investigated the interactions among the fungi Metarhizium anisopliae (Metsch.) Sorok., Beauveria bassiana (Bals.) Vuill., and the larvalpupal parasitoid Oomyzus sokolowskii (Kurdjumov) before and after application of the fungi on DBM larvae offered to the parasitoid. The experiment was carried out at 26 ± 1
