“…bassiana I93-825 was maintained in long-term storage at À80°C on microporous beads (Pro-Lab Diagnostics, Austin, TX, USA). Conidia were mass-produced using our standard 2-stage production system on barley flake (Jenkins et al, 1998;Anderson et al, 2011). Conidia were harvested using a Mycoharvester (Acis Manufacturing, Devon, UK), dried to 5% moisture content over silica gel, sealed in foil laminated sachets and stored at 5°C until use.…”

“…Conidial formulations were applied to substrates (paper or cotton jersey) at a rate of 3 Â 10 6 conidia/cm 2 using an airbrush sprayer (Anderson et al, 2011), to give an equivalent volume application rate of 20 mL/m 2 . Spore formulations were applied to HP™ Color-Laser Paper or jersey knit cotton, which were then cut into 9 cm circles.…”

“…Reducing the non-target mortality would also facilitate the use of the fungus with other biocontrol agents and natural enemies. Transmission of M. anisopliae among host insects [18][19][20][21][22][23] , including M. domestica 24,25 , has previously been demonstrated but rates of transmission and the effects of infection can vary between strains 10,14,26 .…”

BACKGROUND RESULTSMetarhizium anisopliae was transmitted between adult M. domestica flies with 91.67% -100% mortality resulting across the three ratios of infected: non-infected flies tested (1:2, 1:5, 1:10). The mean lethal time (LT50) for female recipients mixed with infected male donor flies at the three ratios were 3.95, 4.79 and 5.65 days, respectively, whereas for male recipients mixed with infected female donors at the same ratios the LT50 were 4.98, 5.98 and 7.44 days, respectively. Infection with M.anisopliae significantly reduced the reproductive capacity of female flies during the first four days of infection with 25% less eggs oviposited by infected flies than those that were uninfected. CONCLUSIONAutodissemination among house flies and reduction in oviposition in the early stages of infection could contribute significantly to the effectiveness of M. anisopliae used in biocontrol programs.

“…Cuticle penetration of the germinating conidia is mediated by mechanical and enzymatic degradation, with later one being highly sensitive to temperature, RH and pH conditions (Goettel et al 1989). After penetration, fungus grows in the host haemolymph, taking up nutrients, producing toxins, destroying host cells and eventually killing the insect (Anderson et al 2011). The defense mechanism of the insect is based on innate components consisting of cellular and humoral factors.…”

Beauveria bassiana HQ917687 virulence to housefly larvae and adult was assessed at different relative humidity, RH (50, 75, 90, and 100 %) and temperature (15, 20, 25, 30, 35, 40, 45°C) conditions at the fungal dose of 10 8 conidia/ml. Depending on the temperature and RH regime tested, difference in mortality rates of housefly adult and larvae were detected. During assay on adult housefly, 100 % mortality was achieved at RH, 90 and 100 % while the temperature of 30°C showed maximum mortality at all the tested humidity conditions. Lethal time, LT 50 was 2.9 days at 100 % RH. Larval mortality at different humidity conditions varied between 30 and 74 %, with maximum mortality at 100 % RH and 30°C. Optimum temperature for B. bassiana virulence to housefly larvae was also found to be 30°C. The interaction between temperature and RH revealed significant effect of RH at moderate temperature range (20-35°C), while such an interaction was not observed at extreme temperatures. The results obtained in this study have useful implications in understanding the pathogen behavior under actual field conditions. This in turn may help devising suitable entomopathogen release schedules for maximum fungal infection.
