A preliminary analysis of the costs and benefits of the biological control agent Dactylopius opuntiae on Opuntia stricta in Laikipia County, Kenya [PDF]

BioControl, 2020
AbstractOpuntia stricta(Haw.) Haw (Cactaceae) is invasive in Laikipia County, Kenya, impacting negatively on biodiversity and livelihoods. To control this invasive plant the biocontrol agentDactylopius opuntiae(Cockerell) (Hemiptera; Dactylopiidae) ‘stricta’ biotype was released in 2014.
