Population dynamics of aphids and its predators alongwith its management

In Pakistan, oilseed cultivations belonging to Brassica genus (Rapeseed, Mustard and Canola) are the most essential crops with respect to eatable oil production. In Indo-Pak, such cultivations have considered as chief oil origins over centuries. This trail was executed at the Ghazi University, D. G. Khan, and Air-Port Campus farming area. The outcomes revealed that insecticidal based treatments significantly reduced the aphid population by the application Bifenthrin and Acetamaprid. In case of botanical extracts, Allium cepa and Moringa oleifera induced mortality of aphid. Moreover, insecticide based treatments reduced percent predator population increasingly than botanical extracts.
