“…Similar studies on the pathogenicity of different B. bassiana isolates also demonstrated their effectiveness in infecting other curculionid species, such as the boll weevil, Anthonomus grandis (Wright and Chandler 1992), the pecan weevil, Curculio caryae (Shapiro‐Ilan et al. 2003, 2004), the chevron water hyacinth weevil, Neochetina bruchi (Chikwenhere and Vestergaard 2001), the pine weevil, Hylobius abietis (Turchinskaya and Sherlyngina 1974), the rice weevil, Sitophilus oryzae (Dal Bello et al. 2001) and the banana weevil, Cosmopolites sordidus (Godonou et al.…”

“…These B. bassiana isolates are indigenous to the province of QC, Canada, and they were collected from cadavers of coleopteran species in Ile Perrot (IP-CPB) (45°23¢N, 73°57¢W), and in Cookshire (CFL) (45°24¢N, 71°37¢W). Similar studies on the pathogenicity of different B. bassiana isolates also demonstrated their effectiveness in infecting other curculionid species, such as the boll weevil, Anthonomus grandis (Wright and Chandler 1992), the pecan weevil, Curculio caryae (Shapiro-Ilan et al 2003, the chevron water hyacinth weevil, Neochetina bruchi (Chikwenhere and Vestergaard 2001), the pine weevil, Hylobius abietis (Turchinskaya and Sherlyngina 1974), the rice weevil, Sitophilus oryzae (Dal Bello et al 2001) and the banana weevil, Cosmopolites sordidus (Godonou et al 2000;Nankinga and Moore 2000). Similar LC 50 and LT 50 values were obtained against P. strobi during this experiment for the isolates CFL and IP-CPB.…”

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.

Beauveria bassiana (Balsamo) Vuillemin was tested under maximum challenge conditions with an estimated dose of 1.1 × 105 conidia/mm2 for its effects on eggs of four of the major beetle pests of stored grain and grain products. When ambient relative humidity (RH) was 92%, hatch of fungus‐treated Rhyzopertha dominica (Fabricius) eggs was 13% versus 58% for control eggs, and hatch of treated Tribolium castaneum (Herbst) was 17% versus 51% for controls. There was no fungus effect at RH of 48 and 73%. Fungus treatment of Cryptolestes ferrugineus (Stephens) and Oryzaephilus surinamensis (Linnaeus) eggs had no effect. Sectioned T. castaneum eggs demonstrated that the fungus penetrates and infects them.

There are several insect species causing serious economic losses in strawberry, Fragaria vesca L., productions. In Quebec, Canada, the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), the strawberry bud weevil clipper, Anthonomus signatus (Say) and the strawberry root weevil, Otiorhynchus ovatus (L.) are the most important pests. We tested the susceptibility of these pests to the entomopathogenic fungus Beauveria bassiana under laboratory conditions. Sixteen isolates were evaluated for their insecticide potential against these insects. Adults of each species were infected by the immersion method. All isolates were pathogenic to adults of all three species, causing mortality rates between 23.3% and 100% at a concentration of 1 × 107 conidia/ml. Based on the screening results, isolate INRS‐CFL was selected for its insecticide potential and then used for further analyses against L. lineolaris, A. signatus and O. ovatus adults. Bioassays were performed to evaluate the lethal concentration (LC50) and the average survival time (AST) of this isolate against both insect species. Results of dose–response mortality bioassays using four concentrations – 1 × 104, 1 × 106, 1 × 108 and 1 × 109 conidia/ml – indicated a LC50 values of 5.3 × 105, 1.8 × 107 and 9.9 × 107 conidia/ml at 7 days after inoculation for L. lineolaris, A. signatus and O. ovatus respectively. Using a dose of 1 × 108 conidia/ml, the AST values were estimated at 4.41, 7.56 and 8.29 days, respectively, at a concentration of 1 × 108 conidia/ml. This study demonstrated the potential of B. bassiana for the management of L. lineolaris, A. signatus and O. ovatus. Results also suggest that the heteropteran species is more susceptible than coleopteran species to B. bassiana.
