Results of Identification of Common Species in Genus Hieroglyphus (Orthoptera: Acrididae) in Hoa Binh Province in 2010-2011

This study aimed to clarify the scientific name of a common grasshopper species belonging to the Hieroglyphus Krauss (1873) genus, which causes serious damage to plantation in Hoa binh province since 1997. Fifty individuals of this species were reared singly at 25⁰C ambient temperature condition for their morphologic characteristic observation and description. These characteristics were collated to those described in taxonomic system of Mistshenko (1952). Our study has confirmed that the species studied is H.tonkinensis Bolivar (1912). Our results of survey on the grasshopper species during 2010 and 2011 at 3 epidemic sites in Hoa Binh province at coordinates of 20053’34”N, 105014’56”E; 20045’53”N, 105015’49”E and 20041’39”N,  105013’44”E indicated that the most common grasshopper species in this province is H.tonkinensis Bolivar (1912). During survey periods this species occurs with high frequency of above 40% and may account for 87% of the population.
