Biodiversity of sericigenous Saturniidae of Manipur in India

Abstract :

The biodiversity of sericigenous Saturniidae producing silks was surveyed, and thirteen different species were collected from the Northeast region of India, particularly Manipur. The collected wild silk moths belong to six genera, Antheraea, Actias, Attacus, Samia,Cricula and Rhodinia. Of these, seven species belong to Antheraea, two to Samia and one each to Actias, Attacus, Criculaand Rhodinia. Antheraeaproylei, A. pernyi, A. assamensis, and Samia ricini are commercially exploited for seed and silk production, while Antheraea roylei, Antheraea compta, Samia canningi, Attacus atlas, Antheraea frithi and Antheraea helferi yield silk products but are yet to be exploited. Seasonal incidence pattern of wild silkworm species revealed that S. canningi and A. atlas occurred throughout the year except December and January. The population densities of a few species like R. newara, A. helferi, A. roylei and A. compta were low and scattered. However, A. frithi population reached more than one lakh in wild condition indicating the best adaptability to build up the population in the prevailing ecological conditions of the region. Economic parameters among the sericigenous species indicate highest 642�33.10m filament length in A. frithi, which is comparable to the commercially exploited species, A. proylei (635�48.05m). Hence sericigenous saturniids have economic parameters and so need multiplication for silk production. Therefore, the need of the hour is conservation of sericigenous species in the region, thereby improving the livelihood of the tribal inhabitants and maintaining the ecological balance
