Now-a-days we are getting so many Beauveria species on variety of insect fauna. It is very difficult to find out the species of insect which are infected. I am ready to collaborate regarding the same.
I have also benefitted from these papers. We got some fungus attacking mites (pests and predatory) on roses and this intrigued us and we would want to know what they are for future mite control.
Dear Dr Kiran there are two simple methods/experiments to know if the fungus is entomopathogenic. Isolate the fungus and 1) spray on leaf to feed the insect 2)spray directly on the insect and observe if that fungus is lethal or not. Rest you would have surveyed the literature, specefic to your fungus.
Fungal growth usually masks the morphological features of the infected insect. Therefore, for traditional identification, you may have to collect apparently healthy individuals from the same host on which you find infected insects. Both infected and healthy insects may be required for comparing certain characteristics. To be doubly sure about pathogenicity of the fungus, you may have to satisfy Koch's postulates. If you are interested in just the fungal isolate, even if you are unable to get the correct name for the insect host, it is fine. Insect identification is possible in our institute or at the Division of Entomology, IARI.
