A scientist from The University of Manchester has hit upon an innovative way to control greenflies which infest our gardens and farms.

Dr Mouhammad Shadi Khudr, discovered that living lacewing insects- which are used as a way to biocontrol greenflies – are also effective after they have died.

Dr Khudr, an evolutionary ecologist based at the University's Division of Evolution and Genomic Sciences, discovered how genetic variations in greenflies' respond to the fear of predation by lacewing – known as aphid lions.

The greenflys' genetic variation and life history influenced how they responded to traces of their predator.

He hit upon the discovery while looking at how different lineages of one species of greenfly responded to lacewings on a crop.

Even though each greenfly line had a distinct way of responding to the exposure to the traces of the aphid lion –they all suffered from dramatic reduction in their reproduction, he says.
