Abstract
A life cycle study of the Tiger moth, Atteva sciodoxa Meyrick., was carried out in the laboratory at an ambient temperature of 27±1 °C, and 200 lux light density. The female moth was laid the eggs singly beneath the Tongkat ali leaves. The neonate of Tiger moth is white and translucent, while the last stage of instar larva is bright yellowish with horizontal black stripe along the dorsal of body. Generally, the metamorphosis of the Tiger moth is complete, passing through three distinct stages, egg, larva and pupa to the adult. The mean total development time from egg to adult for male and female of the Tiger moth were 31.0±3.5 days (range 29-33 days) and 35.2±3.3 days (range 34-38 days), respectively. The larvae of A. sciodoxa passed through five instars larval with the total development duration for male and female larvae is 19.7±1.8 days and 24.1±1.2 days, respectively. The total amount of leaf consumption during the immature stages was 0.176±0.044 g (range 0.135-0.206 g). The water content for young, mature, senescent leaves were 85.81 %, 65.57%, and 59.89% respectively. The higher value in relative growth rate (RGR), efficiency in converting ingested food (ECI), and efficiency in conversion digested food (ECD) were shown that the larvae of A. sciodoxa were more preferred fed on young leaves of Tongkat ali.
