Deltamethrin (as pyrethroid) and Dipel 2x (as bioinsecticide derived from Bacillus thuringiensis subsp kurstaki) was carried out under laboratory conditions throughout the selection pressure until 14 generations. Mechanism of development of resistance was studied at biologicai, biochemical and histopathological levels UR - http://nile.enal.sci.eg/EALE/2006/AAS/106/0/271.pdf ER -
