Growth and development of Spilosoma obliqua on Lantana camara

The paper reports growth, development and field establishment of Bihar hairy caterpillar, Spilosoma obliqua on lantana (Lantana camara) previously not reported as the preferable host. Extensive survey, laboratory experiments and field observations were carried out in 2011–12 and 2012–13. When fed continuously on lantana, life span was 66.43±4.23 days and adult stage duration was found 9.07±0.56 for male and 7.93±0.96 for females. Total larval period was recorded as 42.67±3.15 days and pupal period was recorded as 8.33±0.30 days. The male-female ratio was 4:1. Mean fecundity was observed 366±55.48 eggs pair⁻¹. Larvae were found as efficient fruits, leaves and twig feeder. Two seasonal life cycles were recorded under laboratory conditions and in field.
