Résumé :
Aim: Seed production is the backbone of sericulture in India. In order to cater for the increased demand for seed (egg), the already prevailing seed production techniques need to replace with new and robust techniques. Therefore, the present study was designed to understand the oviposition preference of Antheraea mylitta and selected suitable host plants for future improvement of seed production. Methodology: Choice (nylon net cage) and no-choice (earthen cup) experiments were conducted to study the oviposition preference of A. mylitta on Shorea robusta, Terminalia tomentosa, T. arjuna, Ziziphus mauritiana, Careya arborea, Syzygium cumini and Buchanania lanzan. Mated female moths were released freely into the nylon cage to observe their oviposition preference in the choice test. Whereas, half of both fore wings and hind wings of mated female moths were excised and individually placed in an earthen cup for oviposition. The total number of eggs laid on the host plants in both experiments was recorded and analysed. Results: Mated females released freely within the cage have laid the majority of their eggs on the floor and net instead of their host plants. Among the host plants, the highest number of oviposition was recorded on the S. robusta, T. tomentosa and T. arjuna compared to other host plants. The highest number of eggs per moth was observed on T. tomentosa and followed by S. robusta, T. arjuna and Z. mauritiana, and exceeded the numbers of eggs in the control in the no-choice experiment. Interpretation: The study revealed that both S. robusta and T. tomentosa were highly preferred host plants of A. mylitta for oviposition. Therefore, the volatiles or feeding supplements of S. robusta and T. tomentosa may be identified and applied to A. mylitta during rearing and grainage to enhance seed production. Key words: Host plants, Oviposition preference, Sericulture, Tasar silkworm, Terminalia tomentosa

Résumé :
Aim: The present study was carried out to introspect the effect of temperature, humidity and rainfall on the emergence of Antheraea mylitta Drury. Methodology: An experiment on seasonal and non-seasonal emergence was carried out in 2019 and 2020 at Kathikund and Kharsawan of Jhakhand, India. Meteorological parameters (temperature, humidity and rainfall) were noted twice daily. Similarly number of adult moths emerged were age-graded and segregated as male and female. They were counted twice in a day within the grainage buildings (preservatory of seed cocoons). Results: The emergence of Antheraea mylitta varied month wise following: June to September, March to May, and November to February. Although the emergence of male individuals was more compared to females, no significant difference was observed statistically. Further increase in rainfall (57%) – humidity (15%) triggered more non-seasonal emergence of females. A strong positive correlation between humidity and rainfall with the emergence of adult moths compared to temperature throughout the year across both the seasonal (June-October) and non-seasonal (November-May) months was observed. The erratic/non-seasonal emergence was strongly correlated with humidity (0.75) compared to rainfall (0.32) and temperature (0.19). Daily emergence differed significantly (p<0.01) between the seasonal and non-seasonal months. Interpretation: During seasonal months, the number of adult moths emerged remained almost constant; however in non-seasonal months, the pattern of adult emergence exhibited a non-linear interrupted by sudden intervals of zero emergence. The intervals corresponded significantly to the effect of humidity and rainfall (p<0.001), however, no significant effect of temperature (p>0.05) was observed.

Résumé :
Aim: Variation in total soluble proteins and protease inhibitor levels were investigated to determine nutritional and plant defense status in different leaf types of Terminalia arjuna (Roxb.) Wight and Arn., and Schleichera oleosa (Lou.) Oken, two host tree species of the economically important, non-mulberry Tasar silkworm, A. mylitta. Methodology: Quantitative spectrophotometric assays based on diagnostic amidolytic substrates were conducted to assess serine protease inhibitor activities in young, semi-mature and mature leaf types. A microplate quantification assay for total protein estimations was used with leaf types sampled over a year. Efficacy of total trypsin inhibitor and chymotrypsin inhibitor activities detected in T. arjuna (a primary host plant) was further evaluated on gut extracts of fourth instar A. mylitta and Pieris brassicae L. (a Pierid pest of crucifers) to assess the physiological adaptation of larvae to dietary antifeedants. Molecular provenances with rbcL genes were obtained that are available as NCBI accessions #MN460810 for T. arjuna and #MT010554 for S. oleosa. Results: Intra-specific variations were evident in leaf phenology of two tree species. Generally, young leaf type of both tree species had high levels of total protein and trypsin inhibitory activities, while mature leaf type of T. arjuna had low total protein content and trypsin inhibitor levels. Mature leaf type of S. oleosa had low trypsin inhibitor levels during the months of July and August. Midgut proteases of A. mylitta and P. brassicae were significantly more susceptible (p≤0.05) to both trypsin and chymotrypsin inhibitors detected in young and semi-mature leaf types of T. arjuna than the mature leaf type. Interpretation: In this study, differential inhibition of digestive proteases in A. mylitta and P. brassicae by protease inhibitors from different leaf types of T. arjuna, suggested adaptation to dietary antifeedants. Such reports on nutritional quality, foliar antifeedants, phenology and host plant utilization are relevant for strategies to domesticate the tropical Tasar silkworm, A. mylitta.

Résumé :
Tropical Tasar silkworm Antheraea mylitta Drury (Family: Saturniidae) produces Tasar silk which has very high demand globally and because of their wide range of distribution in tropical regions, they have adapted to different niches forming different ecoraces. In Odisha, alone seven types of ecoraces of A. mylitta have been reported, namely Modal, Sukinda, Nalia, Jata-Daba, Adaba, Umerkote, and Boudh. These ecoraces show differences in their phenotypes, genetic constitution, fecundity, voltinism, etc. In the past few decades, there is the substantial deterioration of habitats due to many anthropogenic activities. This has resulted in a large decline in wild Tasar cocoon production. Lepidopterans are accepted as ecological indicators of ecosystem health and it is apprehended that through anthropogenic and climatic factors this precious genetic resource, which took millions of years to evolve, may face the threat of extinction shortly if adequate conservation measures are not taken. This paper attempts the geospatial mapping of these ecoraces in the state of Odisha through RS and GIS tools, which will provide a greater scenario for their conservation

Résumé :
Taxonomic equivocality and complexity exist in the two species of Ceratopogonids, Forcipomyia (Microhelea) fuliginosa Meigen and Forcipomyia (Microhelea) esakiana Tokunaga. Incongruencies and inaccuracies in species identification restrict further biological and ecological studies on the host-ectoparasite association. Preferential landing and hemolymphophagy of F. fuliginosa and F. esakiana on Antheraea mylitta Drury larva were studied under field conditions. The silkworm A. mylitta is reared in the tasar sericulture industry, contributing 1466 metric tons (2021–22) of indigenous raw silk in India. Ectoparasitic behavior of the biting midges, F. fuliginosa, and F. esakiana is an increasing threat to the silkworm, necessitating proper identification. Intra and inter-variations of these two closely related species have been stated. Morphological-based identification of these species has been substantiated with COX1 molecular data. A Bayesian-modeled approach to reconstruct the dendrogram of the two species based on the COX1 sequences generated has been presented along with the referred sequences of F. fuliginosa from Genebank. The species F. esakiana is being reported for the first time from India, along with its ectoparasitic hemolymphophagous nature. The role of these insectivorous species in transmitting pathogens to the larvae of tasar silk needs further investigation.

Résumé :
Aim: To investigate the integrated use of chemical fertilizer and potential tasar silkworm (Antheraea mylitta) excreta as fertilizer on the growth, yield and quality of rice.. Methodology: A pot experiment was designed in Completely Randomized Design with four replicates with nine treatments, where Terminalia arjuna leaf litter, tasar silkworm excreta and recommended dose of chemical nitrogen fertilizer at 25%, 50% or 100% alone or in combinations was applied in transplanted rice plants. The observations were recorded for different growth parameters at 30, 60 and 90 days interval, while yield traits were recorded at the time of crop harvest. Results: Leaf litter and tasar silkworm (Antheraea mylitta Drury) excreta on growth, yield and quality of rice revealed that application of 100% recommended dose of nitrogen (RDN) from tasar silkworm excreta recorded significantly higher plant height, panicle length, number of grains panicle-1 and 1000 grain weight at rice harvest. While, chlorophyll index, grain yield, number of effective tillers per hill, biological and protein yield of rice recorded significantly higher in 75% recommended dose of nitrogen through chemical nitrogen fertilizer + 25% recommended dose of nitrogen from tasar silkworm excreta. Nitrogen and protein content of grain recorded statistically higher in 50% recommended dose of nitrogen through inorganic fertilizer + 50% RDN from tasar silkworm excreta. Grain yield was significantly correlated with nitrogen uptake and protein yield, plant height, effective tillers per hill, 1000 grain weight, straw and biological yield. Interpretation: Integrated use of 75% RDN through chemical nitrogen fertilizer with 25% RDN from tasar silkworm excreta is suitable for higher production that may reduce the external input of chemical nitrogen fertilizers and promote zero waste management.
