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.Keywords

Biology and feeding potential of Micromus australis Hagen (Neuroptera: Hemerobiidae) was studied under laboratory conditions on Melanaphis sacchari (Zehntner), The predator was observed to pass through three larval instars. On an average first, second and third instars lasted for 2.00 ± 0.0, 1.35 ± 0.49 and 1.76 ± 0.44 days and consumed 58.82 ± 9.68, 67.47 ± 24.56 and 96.18 ± 20.15 aphids, respectively. The fecundity was 818.90 ± 331.81 eggs/female. The individual larvae consumed 213.18 ± 21.95 aphid nymphs to complete the larval duration (5.12 ± 0.49 days) and an adult consumed on an average 585,24 ± 120.49 aphid nymphs over a period of 41.75 ± 11.36 days. Per day consumption of the aphids was 41.82 ± 4.18 and 14,02 ± 9.41 by larva and adult, respectively.Keywords
