Some parameters of Chrysoperla Carnea on floral feeds of castor and feeding potential on selective aphid species

Abstract

The present study entitled some parameters of Chrysoperla carnea on floral Feeds of Castor and Selective aphid Species under laboratory conditions during 2014-2015. The present findings recorded that the maximum of 36.6 days was observed as oviposition period when females were fed with a combination of artificial feed (proteinex and glucose solution), while minimum oviposition period of 24.2 days was observed when females were provided with artificial feed alone. In that order, the maximum of 749.8 eggs per females was recorded when C. carnea were fed on combination of artificial feed + 20g floral, and lowest adult longevity was observed in control. The mean number of aphids consumed throughout the larval period recorded as 309.2±8.11 of Aphis gossypii; 197.6±5.99 of Rhopalosiphum maidis and 130±4.49 of Lipaphis erysimi, and it was also clear from the present study that proteinex along with glucose solution can be used to supplement honey that could result in long survival of male and female C. carnea adults.
