A number of viruses are known to cause the disease in mulberry silkworm, Bombyx mori L. and cause significant cocoon crop loss to the farmers. The study has been undertaken to assess the prevalence of silkworm viral diseases caused by B. Mori Nucleopolyhedrovirus (BmNPV), B. mori Infectious Flacherie Virus (BmIFV) and B. mori Densovirus1 (BmDNV1) through external symptoms and molecular characterization from different climatic regions of India. During the intensive exploratory surveys in 2017, silkworm larvae with typical symptoms of BmNPV, BmIFV and BmDNV1 were collected across seven provinces from North India [Kashmir (temperate), Jammu, Ghumarwin in Himachal Pradesh, Dehradun in Uttarakhand (subtropical) and South India [Karnataka, Andhra Pradesh and Tamil Nadu (tropical)]. Dissection of diseased specimens confirmed the presence of virus through anatomical changes viz, size, shape and colour of organs after disease attack. The viruses were isolated and identified through PCR amplification of highly conserved genes. The results reveal that BmNPV, BmIFV and BmDNV1 are evenly prevalent across India. The infection percentage of BmNPV, BmIFV and BmDNV1 in North India (11.41 ± 1.21, 7.81 ± 0.67 and 7.40 ± 0.61) was significantly higher than South India (1.61 ± 0.17, 1.52 ± 0.14 and 1.62 ± 0.14), respectively. The highest prevalence of these viruses was observed from subtropical followed by temperate and tropical climate. The knowledge of the prevalence of these viruses in India and their synergism with bacteria and influence of other possible factors is important for preventing cocoon crop losses caused by viral diseases in India.Keywords

Trichomalopsis uziae Sureshan and Narendra Kumar (Hymenoptera: Pteromalidae) is a new addition to the already reported parasitoid complex of the tachinid uzi fly, Exorista bombycis (Diptera: Tachinidae), which causes 10-20% reduction to the silkworm (Bombyx mori L.) cocoon production in the states of Karnataka, Andhra Pradesh, and Tamil Nadu. Due to the non-availability of information on its biological characteristics, an attempt has been made in the present investigation to document the parasitism impact of T. uziae female at various densities of its host and reproductive performance of parasitoid at ratios of 1 to 5:5 (Parasitoid: Host) and 1:1 to 50 (P: H). The reproductive performance of the parasitoid was also assessed based on the durations of host exposure for 1 to10 days at a constant P:H ratio of 1:5. The results revealed that there was no perceptible change in the rate of parasitism at different parasitoid densities. However, the progeny production per female was significantly higher (P < 0.01) at a P:H ratio of 1:5 in comparison with 2:5 to 5:5. Further, at a variable host density (from 1 to 50), there was a linear decrease in per cent parasitism with an increase in host density and it was more drastic from a host density in exceed from 15. However, both progeny production and sex ratio increased with an increase in host density, more so from a host density upwards of 15. The host exposure duration and parasitism rate were significantly inferior at 1day exposure, while it was considerably high at other exposure periods. The progeny production was significantly higher at 2 to 5 days of exposure period without much difference in the sex-ratio.
