Aphis craccivora Koch on wheat in Pakistan
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 2
Abstract
Aphids are important insect pest of wheat (Triticum aestivum L.) which affect crop directly through feeding and indirectly by transmitting different viral diseases. Various aphids are reported in Pakistan and their population intensity on wheat crop is observed increasing over the last few years. An aphid specie on wheat was observed during 2009 which has consistent natural occurrence and association with the crop during the subsequent years (i.e. 2010-13) at the Nuclear Institute for Food and Agriculture (NIFA), Peshawar, Pakistan. Morph-taxonomic analyses of 2009 aphid collections were carried out and the aphid was identified as Aphis craccivora Koch commonly called cowpea aphid. This is the first report of Aphis craccivora Koch occurring on wheat in Pakistan. Further studies are needed to confirm this aphid as wheat pest and to explore its potential role as vector of barley yellow dwarf virus (BYDV’s) the cause of barley yellow dwarf disease in cereals.
