Functional response of Chrysoperla rufilabris (Neuroptera: Chrysopidae) to Klamabothrips myopori (Thysanoptera: Phlaeothripidae) under laboratory conditions

Klambothrips myopori Mound and Morris, is widely distributed in California, causing severe leaf distortion on Myoporum sp., a horticulturally important plant species. K. myopori is currently being managed using pesticides and alternative strategies are needed to reduce the risk of resistance. Studies were conducted to develop biological control strategies using Chrysoperla rufilabris. The current study determined the consumption rate of C. rufilabris at constant densities of K. myopori eggs, 1^st instars, 2^nd instars, propupa and pupa and defined the functional response of predator females. The predator consumed significantly more instars than other prey stages, and displayed different types of functional response depending on prey stages.
