Author(s): JS Tara, Madhvi Gupta
Abstract: Detailed bionomics of Euthalia aconthea (Common baron fly) has been recorded for the first time in J&K on mango plantations. The insects were reared in the laboratory at temperaturernranging between 24 °C-39 °C and relative humidity of 26%-80%. Caterpillars cause considerable damage to mango trees. There are five instar stages. Caterpillar of this butterfly while feeding on the mango trees took about 24-32rndays to develop from first instar to mature larva. Larvae defoliate mango plants, reduce their vigour. Thus, an attempt was made to study the biology of this pest in Jammu as no earlier record of the pest has been obtained from thernregion so far. Biological studies include morphometric measurements of different stages from egg to adult. Larval period varies from 24 to 32 days. Pupal period ranges from 7.5 to 8 days (7.75±0.25days). Adult longevity is 8-12 days with an average of 10.00±1.50 days respectively. So far, no report is available on culture of Euthalia aconthea.
