It was the first time the survey of entomopathogenic fungi infecting aphids was conducted in this subtropical - tropical region, a great species diversity of fungal pathogens including 9 entomophthorales and 1 hyphomycete entomopathogens were observed. Over 4000 alates of three species aphids were trapped from air, 19.22% of them were infected by fungal pathogens and survived less than 3 days although only 5 of 741 B. brassicae were infected , P. neoaphidis was predominant, and most of the infection occurrence in monsoon season over 75% RH. Infected alates from air have proved highly capable of independently initiating progeny colonies in which the fungal infection could be transmitted.
