Odoiporus longicollis Oliver and Cosmopolites sordidus Germar are important pests for damaging bananas in China (Zhang, 1999).
Polytus mellerborgi, a native of Indo-Malaya, has become widely spread by commerce and is now present over much of the tropical
world where bananas are grown from southeastern Polynesia through Melanesia, Micronesia, Indo-Malaya, south China, Burma, India,
Ceylon, islands of the Indian Ocean to Madagascar, etc. (Zimmerman, 1968). The aim of this scientific note is to inform and alert
about the geographical spread of banana weevils, which are important pests of bananas in Hainan Province, China. Particularly, our
main goals were to identify a new record species and to determine its current distribution. A survey for the presence of banana weevils
was conducted in 11 cities (counties) in Hainan Province from May 2008 to December 2009. Levels of infestations and banana
damages were evaluated in about 5 plots per site. The incidences of infestations were determined by visual symptoms of stalk boring
(n = 30 plants/plot) and dissecting leaf sheaths outside stalks for identifying and counting the adults based on occurrence level from
Lu et al. (2002). Most specimens are deposited in Environment and Plant Protection Institute, Chinese Tropical Agricultural Sciences.
O. longicollis, C. sordidus and P. mellerborgi were all found in commercial banana fields in Hainan Province. O. longicollis occurred
mainly in Ledong.....
