Abstract:

Labiratory experiment was conducted to evaluate comparative bio-efficy of certain naturally occurring indigenous plant extracts against destruction of Bihar hairy caterpillars, Spilarctia obliqua Walker (Lepidoptera: Arctiidae) under mustard agroecosystem. The unripe fruits of Annona retoculata Linn. (Annonaceae), leaves of Pongamia glabra Vent.(Fabaceae), arial parts of Lantana camara Linn. (Fabaceae), leaves of Piper nigrum Linn (Piperaceae) were collected from Kanpur region. The collected plant materials were dried in shade, make them powder farm and extracted them with the help of soxhlet apparatus using alcohol as solvent. From stock solution different concentrations (0.5, 1.0 and 2.0 per cent) were prepared from each plant extract. Three treatments were used and each treatment with three replication were introduced. The data were dipected from results that unripe fruits extract of Annona reticulata showed maximum larval mortality 67.90 per cent and placed at top followed by leaves of Pongamia glabra 66.80 per cent, leaves extract of Piper nigrum Linn 62.62 per cent larval moratality, whereas extract of Lantana camara gave only 50.57 per cent larval mortality to the Bihar hairy caterpillars, Spilarctia oblique Walker under laboratory conditions.
