Feeding potential and development of <em>Chrysoperla carnea</em> (Neuroptera: Chrysopidae) on <em>Paracoccus marginatus</em> (Hemiptera: Pseudococcidae) under no-choice conditions

Abstract

Purpose: Considering the predatory effectiveness of Chrysoperla carnea (Neuroptera: Chrysopidae), studies were carried out at National Agricultural Research Centre, Islamabad, Pakistan to determine the feeding potential and developmental period of its larval instars on Paracoccus marginatus (Hemiptera: Pseudococcidae).Research Method: Eggs, 1 st , 2 nd , and 3 rd nymphal instars and adults of P. marginatus were provided to all three larval instars of C. carnea in a Completely Randomized Design experiment, replicated ten times. Findings:Results indicated that all C. carnea larval instars were found to feed on all P. marginatus stages.
