“…Numerous entomopathogenic fungi are currently used to control insect pests. The entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin (Hyphomycetes) is a well‐known, naturally occurring and widely distributed natural pathogen of various coleopteran pests (Gottwald and Tedders 1983; Khan and Selman 1984, 1987, 1988; Rodrigez and Pratissoli 1990; Ardan 1994; Padin et al. 1997).…”

Studies were conducted under laboratory conditions to document the potential of Beauveria bassiana conidia applications for controlling the white pine weevil, Pissodes strobi (Peck). A screening test including six B. bassiana isolates allowed us to demonstrate that CFL (Centre de Foresterie des Laurentides) and IP-CPB (Iˆle Perraultcharanc¸on du pin blanc) were the most virulent isolates among the ones tested, with percentages of mortality after 3 weeks of 73% and 85.5%, respectively. These two B. basiana isolates were applied either onto soil or branch sections to compare the effectiveness of these potential control strategies. Greater than 75% mortality was observed within 3 weeks for both modes of application using suspensions of B. bassiana at a concentration of 1.0 · 10 8 (soil application) and 1.0 · 10 9 conidia/ml (branch application). The results demonstrate for the first time that B. bassiana is an effective entomopathogen against P. strobi.

“…Alternative approaches to the conventional use of synthetic insecticides and Bt‐toxins for the control of DBM are highly appreciated because of increasing importance of integrated management strategies relying on biocontrol possibly combined with selective insecticide application. Entomopathogenic fungi (EPF) are considered the most promising alternative approach because they are currently being developed as biocontrol agents of many insect species (Ibrahim and Low 1993; Padin et al. 1996, 1997, 2002; Selman et al.…”

Recently, formulated forms of EPF have been used against various insect species, and inverted emulsion formulations (water-in-oil type) are used as a promising formulation for these entomopathogens when applied as biocontrol agents of insects (Batta 2003a(Batta ,b, 2004(Batta , 2005(Batta , 2007(Batta , 2008Batta and Abu-Safieh 2005;Michalaki et al 2006).…”

Aims: To isolate and formulate a native strain of Zoophthora radicans naturally infecting larvae of diamondback moth, Plutella xylostella, existing in South Australia and to provide evidence that formulation of the fungus is effective against P. xylostella larvae, and therefore, it could be used as a tool in pest management of this insect. Methods and Results: Dose–response bioassays using formulated and unformulated forms of the fungus strain were carried out against third instar larvae of P. xylostella. Results obtained have indicated a significant increase in the larval mortality when higher concentrations of a formulated form of the fungus strain were applied compared to the treatments with the unformulated form (85·0 vs 57·5% of larval mortality, respectively, at the top concentration of 107 conidia/ml). The median lethal concentration (LC50) for a formulated form was 100 times less than that of the unformulated form when they were applied against the third instar larvae of P. xylostella. In addition, the formulation used in the present bioassays has preserved the viability of introduced fungus conidia for longer time in comparison with the unformulated conidia. Conclusions: The effective application of a formulated fungus strain against P. xylostella larvae constitutes the first step towards its use in pest management of this insect. Significance and Impact of the Study: The formulated fungus in inverted emulsion could be used as an alternative tool to insecticides in pest management of P. xylostella larvae because of the development of resistance to insecticides in the treated larvae.

“…The possibility of using fungal pathogens to control insects has been studied for many years but little attention has been paid to the use of fungi as control agents against storage pests (Khan and Selman, 1988;Rodrigues and Pratissoli, 1990;Adane, 1994;Adane et al, 1996;Padı´n et al, 1997;Hidalgo et al, 1998;Moino et al, 1998).…”

This research was carried out to evaluate the suppressive efficacy of entomopathogenic fungi Beauveria bassiana against adults of Callosobruchus maculatus (F.) and Sitophilus granarius (L.) on stored grains in darkness (27±2°C and 65±5% RH). The insects were inoculated by following immersion in five aqueous suspensions with concentrations determined with preliminary tests and compared with untreated wheat and cowpea as control. Probit analysis showed that the lowest LT 50 values in suspensions with highest concentrations (2.3 × 10 7 conidia ml -1 ) were 6.63 and 10.45 days for C. maculatus and S. granarius, respectively. On the other hand, the LC 50 values on day 9 post-treatment were 3.17 × 10 6 and 6.08 × 10 7 con.ml -1 for C. maculatus and S. granarius, respectively. Comparison of Lc 50 , LT 50 values and mortalities indicated that in both assays, B. bassiana was consistently more virulent for C. maculatus than S. granarius. The overall results showed that these two pests were controlled successfully with entomopathogenic fungi Beauveria bassiana.
