FUNCTIONAL RESPONSE OF Nabis punctipennis Blanchard to Acyrthosiphon pisum Harris IN THE LABORATORY [PDF]

open access: yesChilean journal of agricultural & animal sciences, 2017
ABSTRACT This study analyzed the predatory behavior of adult females of Nabis punctipennis Blanchard (Nabidae) towards Acyrthosiphon pisum Harris (Aphididae) in the laboratory in order to determine its functional response and potential as a biological control agent of this aphid. Both hemipterans are common in alfalfa, Medicago sativa L., in Chile. The
