Antheraea frithi Moore, the source of wild tasar silk, is an indigenous wild silk moth of north-east India. The detailed life history, bionomics and rearing performance of A. frithi in relation to a newly reported food plant, Terminalia arjuna (Roxb.) has been described in the present study. Life cycle of A. frithi has five larval instars. The first instar larva measures 1.98 ± 0.13 cm × 0.198 ± 0.010 cm in length and breadth and 0.0142 ± 0.002 g in weight while the fifth instar larva measures 6.98 ± 0.18 cm × 1.12 ± 0.13 cm in length and breadth and 4.76 ± 0.45 g in weight. Wing span of male and female is recorded as 11.4–13.5 and 13.0–14.7 cm respectively. The incubation period (6–7 days), larval duration (35–39 days), fecundity (162–176 eggs), hatching (78–81 %), effective rate of rearing (57–59 %) and cocoon yield (67–79 nos) has been recorded. The reelable cocoons with a filament length (mts) and filament denier (d) is 493–575 m and 4.6–5.3 respectively. The shell weight (g) of male and female cocoons measures as 0.19–0.39 and 0.2–0.6, respectively. The shell ratio (%) for male and female cocoons stands as 8.1–8.4 and 9.4–9.8 % respectively. 相似文献
