| Abstract: | A new fungal pathogen Entomophthora erupta infecting Cyrtorhinus lividipennis was found during a survey of pathogens of C.lividipennis in Guangdong province,China in 2009.The fungus caused an epizootic in rice fields during autumn 2009,with infection rate in C.lividipennis reaching 33.1%.The main stages of C.lividipennis infected with the fungus were adults or 3rd,4th and 5th instar nymphs.Infection rates from the 3rd,4th and 5th instar nymphs and the adults of C.lividipennis populations were 2%,6.7%,8.3% a... |
