Penicillum oxalicum spg1: A novel entomopathogenic fungus isolated from mummified Bemisia tabaci (Gennadius) of cotton

摘要: Whitefly has assumed the status of a serious pest cotton in north India recent past due to its severe attack on crop. The productivity crop fallen substantially from 574 kg ha-1 lint year 2014 -15 197 2015-16 Punjab. During extensive epidemiological surveillance whitefly month September 2016, mummified whiteflies with fungus were noticed both abaxial and adaxial surfaces leaves infested plant at village, Mandi Khurd, Mansa District Punjab, Punjab Agricultural University, Regional Research Station, Bathinda, India. was isolated purified white fly characterized molecular level by sequencing 633 bp D2 region Large Subunit (LSU) rRNA gene identified as Penicillium oxalicum spg1. sequence been submitted NCBI, USA accession no. KY214238. microscopic studies (stereo- scanning electron) further strengthen entomopathogenic potential P. There are few reports spg1 against other insects pests. To our knowledge, this is first report isolation identification fly. It’s biocontrol agent can be exploited promising way nominal interference biological equilibrium.
