Effect of varietal feeding on larval duration and cocoon parameters of six strains of eri silkworm
Samia ricini

earing of six strains of
Samia ricini
(eri silk worm) i.e. Yellow plain (YP), Yellow spotted (YS), Yellow Zebra (YZ), Greenish
blue plain (GBP), Greenish blue spotted (GBS) and Greenish blue zebra (GBZ) was conducted on
Ricinus communis
(Castor),
Heteropanax fragrans
(Kesseru),
Evodia fraxinifolia
(Payam) and
Manihot utilissima
(Tapioca) to evaluate the effect of seasonal pattern
on larval duration and cocoon parameters in Nagaland, India. Larval duration during spring season was maximum in all strains in all
food plants; however minimum for all strains was recorded during summer season on Castor, Kesseru and Tapioca. Cocoon weight
was recorded to be minimum (2.8±2 0.55 gm) in YP on Kesseru and maximum (4.06±0.68 gm) in GBZ on Castor during spring
season; shell weight fluctuated between 0.34±0.08 gm during spring in GBS on Kesseru and 0.58±0.09 gm during summer in YZ
on Castor and percentage of silk ratio was found to be minimum and maximum in YP on Payam during spring (11.37±1.29) and in
GBS on Castor during summer (16.05±1.59) respectively. The variation in larval duration and cocoon parameters reflected variation
in nutrient composition of food plants and dynamic environment conditions prevailing in 1different seasons of the year. Payam and
Tapioca plants could be fed either singly or alternately with Castor or Kesseru to attain the commercial advantage to ensure more
value added production. While there were differences in the productivity parameters with respect to strains and seasons, the present
study shows that all the strains on four host plants expressed adoptability and suitability for commercial rearing under Nagaland
climatic condition.
Biography
L N Kakati is presently Head, Department of Zoology, Nagaland University, Nagaland, India and teaches Ecology & Environmental Biology, Biosystematics,
Evolution and Bio statistics in the postgraduate level. He has more than 30 years of research experience of wild silk moth biology and travelled extensively in
different hilly states of North Eastern region of India for exploration of wild silk moths. He completed three research projects and presently undertaking two new
projects sponsored by different funding agencies in India. Four students have been conferred Ph.D degree under his guidance and four students are presently
pursuing research with him. He visited Khonkaen University, Thailand and Tokyo Agricultural University Tokyo for presentation of scientific papers in International
seminars. He attended 48 seminars, chaired in technical sessions and delivered lectures in seven seminars as invited Resource person/Keynote speaker. He is
presently member of 12 scientific associations and published 70 research papers.
