Fig. 2From: Insecticidal effects of deltamethrin in laboratory and field populations of Culicoides species: how effective are host-contact reduction methods in India?Knockdown and mortality of laboratory reared Culicoides nubeculosus. Knockdown of laboratory reared C. nubeculosus recorded 1 h after exposure to deltamethrin papers in WHO tubes (a) and mortality recorded 24 h after exposure (b). Knockdown was assessed as an insect not able to remain on its feet after gently tapping the tube. Grey bands indicate 95% confidence intervalsBack to article page
