Ctenocephalides felis is an ectoparasitic flea species commonly found on dogs and cats. The current study verified the in vitro virulence of conidia of the entomopathogenic fungus Beauveria bassiana produced under different color LED light (red, blue, purple, green, yellow, and white) to adults of C. felis. The fungal isolates were cultivated on malt extract agar (MEA). Bioassay treatments used aerial conidia in test tubes. Adult fleas were obtained from a house cat in Chiang Mai province, Thailand. The experiments were composed of one control and eleven treatment groups. All of the treatments with B. bassiana conidia caused adult mortality after an exposure of 12 h. Among the conditions used in this study, B. bassiana cultured under red LED and fluorescent light were the most effective in causing mortality (100 %) in adult fleas after 36 h. The experimental results indicate that these aerial conidia of B. bassiana have promising potential for use in control of C. felis adult stages.

Beauveria bassiana is an important entomopathogenic fungus that used as a biocontrol agent of insect pests. Maintaining and preserving B. bassiana cultures is essential for the effective evaluation of its potential as microbial agent against insect pest, for biodiversity studies and also for exchange of fungal material between laboratories. In the present work we evaluated the suitability of four preservation materials based on gelatin and rice to maintain the viability of B. bassiana to be used as baits for insect’s control. The gelatin amended with sugar recorded the maximum viability after 70 days of storage as 98.3% compared to 63.3% on rice media. Effective control of 80% of the ants was observed after 10 days of feeding on gelatin amended with sugar and rice bait. The results demonstrated that treatment with formulations containing conidia of B. bassiana presents insecticidal activity against ant in addition of acting as preservation materials.

Microbial control agents targeting soildwelling organisms need to be compatible with commonly used fertilisers The bacterium Serratia entomophila is used as a microbial control agent for control of the New Zealand grass grub Costelytra zealandica and Beauveria bassiana is an entomopathogenic fungus used to control a range of insect pests These biocontrol agents were formulated into granules and applied to pots together with five fertilisers commonly used on pastures throughout New Zealand Compatibility with S entomophila was also assessed in a field trial where treatments were applied by direct drilling and surface application There appeared to be no deleterious effect from the application of the fertiliser treatments on the establishment and survival of either S entomophila or B bassiana On the contrary there was a suggestion that some nitrogenous fertilisers may lead to an increase in numbers of the bacterial biocontrol agent
