INTRODUCTION •Eri silkworm, Philosamia ricini is multivolitine and their cocoons are open mouthed. Unlike all the other silk worms, the Philosamia ricini caterpillar does not spin one continuous strand of silk when making its cocoon. ARPN … Circulatory system, blood and immune system 6. 0000158428 00000 n Both pupation rate and neatness defects in the trimolters were slightly improved than in the tetramolters. The rearing periorinance of different eco-races of eri silkworm Philosamia ricini was studied during autumn season of year 2006 and 2007. 0000113952 00000 n 0000159573 00000 n 0000034187 00000 n 0000141693 00000 n Two species of wild silkworms, the Chinese oak silkworm (Antheraea pernyi) and the castor silkworm Philosamia cynthia ricini, can acquire a serious disease caused by Nucleopolyhedrin Viruses (NPVs) (known as AnpeNPV and PhcyNPV, respectively). 0000122619 00000 n 0000078205 00000 n 0000150541 00000 n 0000038267 00000 n 0000028929 00000 n 0000087206 00000 n evolutionary temperature adoption. 14. 0000049297 00000 n xref 0000101114 00000 n 2013). is also known as Endi or Errandi and it belonging to family saturniidae. A study conducted at Mulberry Silkworm Seed Station (MSWSS), Chandka, has shown that the quality of cocoons can be improved and larval period can be reduced by adopting improved techniques of rearing. There are eyespots on the outer forewings. 0000109236 00000 n 0000117162 00000 n 0000138666 00000 n The Borduar eco-race of P. ricini showed better rearing performance than Titabar, Dhanubhanga and Mendipathar eco-races. 0000043702 00000 n The sensilla basiconica present on the maxillary palp of P. ricini larvae respond to gustatory, mechanical, and olfactory stimuli (Barsagade et al. The secondary structure and thermal behavior of SF powder were determined by FT-IR and TGA analyzer, respectively. ↑The author is most commonly cited as "(Boisduval)" referring to Boisduval, 1854, Ann. 0000029217 00000 n Carbohydrate-Binding Module Family. Eleven inbred silkworm lines (M-101, M-103, M-104, M-107, Pak-1, Pak-3, Pak-2, Pak-4, PFI-1, PFI-2, and S-1) were evaluated for various parameters of cocoon production under different temperature and relative humidity conditions ( 25 ± 1 , 30 ± 1 , and 35 ± 1 ° C in combination with 55, 65, and 75% RH for three hrs during 4th and 5th instar. 0000120096 00000 n 0000147707 00000 n 0000049688 00000 n 0000125439 00000 n 0000044478 00000 n 0000088884 00000 n Samia ricini is a non-mulberry, multivoltine, domestic moth, reared indoor.

The average length, breadth, weight and duration of the fully grown Vth instar larvae were found to be 84.21±0.50 mm, 18.59±0.54 mm, 17.98±0.37 g and 13.72±0.13 days, respectively. 0000010994 00000 n The cumulative evaluation index values for different traits showed that Pak-4 (61.42) was the best line followed by M-101 (59.15), Pak-2 (56.37), Pak-3 (52.83) PFI-I (52.62), and M-107(50.03).
