Abstract

The aim of the present study was to evaluate the direct attack of the oriental hornet Vespa orientalis L. against local Iraqi honeybees Apis mellifera L. at the some middle governorates in Iraq through 2009,2010 and 2011.Results showed that the direct mortality of beehives caused by hornets in 2011 was generally higher than those of 2010 and 2009 which were reached to 28.1 , 27.7 and 20.2 % respectively . The beehives in Wasit governorate were highly affected by the hornet ,then Al-Najaf , Kerbala and Al-Qadissiya, which were 30.9 , 24.89 , 23.1 and 22.64 % respectively . It can be concluded that the impact of the hornet was progressively increased through 2009 to 2011 , which may belong to the increasing of global warming .
