Abstract

Studies were made to explore the potentiality of Micromus igorotus for the management of aphids in cotton (Aphis gossypii G.), sorghum (Metanaphis sachari Zehntner) and safflower (Uroleucon carthami Theo.) ecosystems during November 2004-December 2005 at main Agricultural Research Station, University of Agricultural Sciences, Dharwad, Karnataka, India. Post-release observations revealed the presence of a mixture of brown lacewing larvae distinctly different from that of M. igorotus in cotton and sorghum ecosystems. These were identified as Micromus australis Hagen and Micromus timidus Hagen occurence of M. australis in cotton and sorghum ecosystems and on the prey aphids constitutes a new record.
