“…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.

“…The value observed for C. sordidus mortality (20.2%), caused by isolate CNPMF 218 (Table 2), was similar to that registered by Khan & Gangapersad [19], in Trinidad and Tobago (20%). Several authors mentioned reductions in the insect population caused by B. bassiana [4, 5, 9, 12], although comparisons are difficult because different methodologies have been used. Efforts to develop a standardized methodology should be made, by monitoring B. bassiana application under integrated management of C. sordidus .…”

“…Thus, the use of biological control agents, such as entomopathogenic fungi, has been considered a useful alternative to pest control. In fact, Beauveria bassiana is one of the most studied entomopathogenic fungi, worldwide, aiming at C. sordidus control [1, 3–5]. …”

The objective of this study was to select strains of Beauveria bassiana for controlling Cosmopolites sordidus (Germ.) in plantain farms (cv. Terra) of the “Recôncavo” and southern regions in the state of Bahia, Brazil. The virulence of 32 B. bassiana isolates against C. sordidus was determined under laboratory conditions. Three isolates (CNPMF 407, CNPMF 218, and CNPMF 416) were selected for evaluation under field conditions in plantations located in the counties of Mutuípe and Wenceslau Guimarães. Population of C. sordidus was estimated every 15 days by using pseudostem traps. The efficiency of the three strains of B. bassiana was compared to chemical control (carbofuran, 4g/trap) and absence of control. Carbofuran caused around 90% of adult mortality after 12 months, with a reduction in the population of C. sordidus since the first evaluation. A low number of trapped insects was observed in the fungus-treated plots, suggesting the efficiency of the isolates in controlling the C. sordidus population. The strain CNPMF 218 was the most efficient in controlling C. sordidus adults in both locations, causing around 20% mortality, leading to 40% population size reduction after 12 months.

“…Application of botanical pesticides such as neem extract in cake form increases yields in weevil infested plots (Musabyimana et al, 2000). Reduction of weevil populations also has been achieved by application of entomopathogenic nematodes at high baiting density (>1,000 points/Ha/yr, Treverrow, 1994;Nankinga and Moore, 2000) but the high application rate has discouraged this technique. Dissemination of the entomopathogenic fungus Beauveria bassiana that infects both larvae and adult Coleoptera, has been reported to be significantly increased when pheromone traps are used to attract weevils to the area in which this pathogen has been applied (Tinzaara et al, 2007b).…”

Management of Cosmopolites sordidus and Metamasius hemipterus in Banana by Pheromone-Based Mass Trapping

Mass trapping Cosmopolites sordidus (Coleoptera, Curculionidae) using a pheromone-baited pitfall trap and Metamasius hemipterus (Coleoptera, Curculionidae) using a pheromone-sugarcane-baited open gallon trap was conducted in commercial banana. Four traps for each insect per hectare were placed in each of two 5-hectare plots of banana. Two additional 5-hectare plots were designated as controls and treated according to the plantation protocol. Capture rates of C. sordidus and M. hemipterus declined by >75 % over 10-12 months. In the banana growing region studied, corm damage was due primarily to C. sordidus, while only a minor amount of damage was attributable to M. hemipterus. Corm damage reduction in trapping plots was, thus, attributed primarily to C. sordidus trapping. In trapping plots, corm damage decreased by 61-64 % during the experiment. Banana bunch weights increased 23 % relative to control plots after 11-12 months of trapping. Fruit diameter did not vary between bunches harvested from trapping plots vs. control plots. Plant vigor, however, as determined by stem circumference at one meter above ground increased in plots with traps compared to control plots. Trapping for C. sordidus in two plantations of over 200 hectares each, reduced corm damage 62-86 % relative to pre-trapping levels. Insecticide control measures in place when the experiment commenced resulted in about 20-30 % corm damage, while use of pheromone trapping to manage C. sordidus lowered corm damage to 10 % or less. It is estimated that the increase in value of increased yield obtained in this trial (23 %) is about $4,240 USD per year per hectare, while the cost of pheromone trapping is approximately $185 USD per year per hectare. The trapping program becomes revenue neutral if bunch weights increase by an average of 1 % per year of trapping. Approximately 10 % of all plantation area in Costa Rica use the pheromone trapping system described here. The system also is used in Martinique, Guadeloupe, and the Canary Islands.
