ABSTRACT

Second instar larvae of Chrysoperla carnea were released on green peppers in a green-house in order to control an aphid population of Myzus persicae. Over a study period of nearly 16 weeks, successful control was obtained in the treated green-house as the aphid population was maintained below the economic threshold (around 20 aphids/plant), however, in the control greenhouse where no larvae were released the aphid population underwent its exponential growth to reach 2384.5±380.5 aphids/plant, most of the control plants were with less foliage, flowerless and fruitless.

Key Words: Chrysoperla carnea, release, Green-houses, Green pepper.
