EVALUATION OF MORPHOTYPES OF SOM, PERSEÁ BOMBYCINA KOST. FOR THE PREARING COF MUGA SILKWORM, ANTHERAEA ASSAMENSIS HELFER (LEPIDOPTERA: SATURNIDAE)

Abstracts

 

The som, Persea bombycina Kost major food plant of muga silkworm shows various morphotypes within the species. Eight (PB 001, PB 002, PB 003, PB 004, PB 005, PB 006, PB 007, PB 008) morphotypes of som food plant maintained at Regional Muga Research Station, Boko were evaluated for rearing performance of muga silkworm, Antheraea assamensis Helfer during Kotia commercial (October – November 2012) and Chotua seed crop (February – March 2013) rearing seasons. Among the eight morphotypes higher moisture percent was recorded in the tender leaves of PB 003 (69.70%) followed by PB 006 (67.50%) and least in PB 002 (61.02%) during Kotia commercial crop rearing. The mature larva weight (11.30 g), effective rate of rearing (59.66%) and cocoon yield (61 cocoons/ g) recorded were highest in muga silkworm fed on PB 003 morphotype of som followed by batch of larvae fed on PB 006 morphotype and least in larvae fed on PB 002. Data of important cocoon characters like single cocoon weight, single shell weight and silk ratio of muga silkworm fed on different morphotypes were different. The single cocoon weight was ranged from 5.31g to 5.45 g, Shell weight 0.42 to 0.46g and Silk Ratio percent 8.02 to 8.66%. The rearing parameters i.e. mature larva weight, Effective rate of rearing and cocoon yield per/dfl and cocoon parameters i.e. single cocoon weight, single shell weight and silk ratio were observed higher during Kotia commercial crop than that of Chatua seed crop of muga silkworm fed on different morphotypes of Som. The score of evaluation index of rearing and cocoon parameters indicated that PB 003 was more suitable for muga silkworm rearing as received highest score of 411.21 which was followed by PB 006 having score 408.24 during Kotia commercial crop. Similar trend was observed during Chotua seed crop.

ROLE OF CERTAIN PHYSICO-CHEMICAL PROPERTIES OF WATER ON ABUNDANCE OF TREMATO DE PARASITES OF CHANNA PUNCTATA (BLOCH) IN SONE BEEL, ASSAM INDIA

Abstracts
Helminth parasite infection in fishes by trematode (Liver fluke : Parasitic flatworms having external suckers for attaching to a host) parasites can lead to severe change in nutrient content and may result in host mortalities and character of a water body may influence the parasitic fauna. Hence a study was carried out from January 2014 to December 2014 to find out the effect of physico-chemical characteristics of water on the abundance of trematode parasites of Channa punctata (Bloch) in Sone Beel, Assam, India. During the present investigation two species of trematodes were recorded. In the present study We had come across concurrent infections by two parasite species. Percentage abundance infection is positively correlated to pH (r = 0.688, p-0.05), Dissolved oxygen (DO mg/L) (r. = 0.847, p<0.01) and Water Temperature (WT) (r. = 0.720, p<0.01) but negatively correlated with Total Alkalinity (TA), Dissolved oxygen (DO mg/L) is positively correlated with pH (r= 0.668, p<0.05), Free carbon dioxide (FCO) is also positively correlated with pH ( r = 0.763, p<0.001), & Dissolved oxygen (DO mg/L) at r = 0.615, p<0.01, TA mg/L is negatively correlated with free carbon dioxide and water temperature strongly correlated with percentage abundance (r = 0.720, p<0.01), pH (r = 0.863, p<0.01), DO (0.808, p:0.15), FCO (r = 0.669, p<0.05) and negatively correlated with TA. The mean Abundance, Water temperature (WT), pH, dissolved oxygen (DO mg/L), free carbon dioxide (FCO2 mg/L) and Total alkalinity (TA mg/L) respectively 60.15%, 27.3°C, 6,7, 5.3 mg/L. 12.2 mg/L and 44.43 mg/L. Seasonal variation in the occurrence of these parasites are also effected by certain ecological conditions, particularly distribution of intermediate hosts and also the age of the host and the life cycle of the parasite species.

CHARACTERIZATION OF RHIZOSPHERE AND RHIZOPLANE MICROFLORA OF SACCAHARUM OFFICINARUM

Abstracts

 

The microflora from rhizosphere and rhizoplane of Saccharum officinarum was studied and characterized. The total viable count of Nutrient agar plates was observed greater in Rhizospheric sample than rhizoplane sample of sugarcane plant S officinarum). Total viable count of Potato Dextrose Agar (PDA) plates was also observed greater in rhizospheric sample than rhizoplane sample. This indicates that microbial number and enzyme activities were higher in the rhizosphere than rhizoplane or root surface. In the present study bacteria like Pseudomonas, Azotobacter, Proteus, Azospirillum, Burkholderia, Rhizobium, Bacilius, Escherichia coli and Herbaspirillum were found in rhizosphere and rhizoplane of sugarcane plant. Among the fungal population isolates obtained were Aspergillus, Cladosporium, Fusarium, Penicillium, Trichoderma and Rhizopus.

NOCTUIDAE (INSECTA : LEPIDOPTERA) OF MUZAFFARNAGAR FROMUPPER INDO-GANGETIC PLAIN

Abstracts

 

A survey conducted for the collection of Noctuidae from Upper Indo-Gangetic plain, Muzaffarnagar, in particular, the survey resulted into a record collection of 47 noctuid species represented by 36 genera and 13 subfamilies. The present attempt has been first of its type. Hampson (1892 & 1894) have used for determination of noucid species including Arctiidae and Lymphatidae as subfamilies of Noctuidae. The noctuids reported from Varanasi and Palamau ecosystems have also been compared with the noctuids recorded from Upper Indo-Gangetic plain ecosystem together with their food plants. The Catocalinae remain dominant and rich. Spodoptera lilura (Fabr.) assessed being recorded in all 3 ecosystems. Noteworthy, have been the determination of synonyms of the noctuid species, and revision of subfamily placement by British Museum.

IMPACT OF STORAGE DAYS ON THE EMERGENCE OF TRICHOGRAMMA JAPONICUM ASHMEAD (HYMENOPTERA : TRICHOGRAMMATIDAE)

Abstracts

Trichogramma japonicum Ashmead is commonly used biocontrol agent through inundative field release. The impact of storage of T. japonicum for different days (10, 15, 20, 25 and 30 days after parasitization) for different life stages (egg, larval and pupal) at 10°C was studied under laboratory condition. It was observed that there was significant reduction in adult emergence from parasitized Corcyra cephalonica (Stainton) eggs containing egg, larval and pupal stages of T. japonicum due to storage. Maximum adult emergence (59.4%) was observed when the egg stage of T. japonicum was stored for 10 days and percent adult emergence decreased upto 34.7% when storage period extended to 30 days. The percentage of adult emergence ranged from 55.8% (at 10 days after storage) to 33.7% (at 30 days of storage) in larval stage. Storage of T. japonicum at pupal stage (7 days after parasitization) exhibited maximum adult emergence (64.5%) as compared to both egg and larval stages.

ORTHOPTERA (INSECTA) FROM MUZAFFARNAGAR, A TERAI DISTRICT INNORTH-WEST OF UPPER INDO-GANGETIC PLAIN, INDIA

Abstracts

The grasshoppers and locusts together with nymphs are the destructive insect defoliating the uncultivated and cultivated green vegetations and belong to the superfamily Acridoidea under Orthoptera (Insecta). The present study has been undertaken to characterize the Orthopteran insects of Muzaffarnagar in particular, situated as a part of north-west of Upper Indo-Gangetic plain, located at the base of Himalayan and Shivalik ranges. This part has been recorded with 33 species under 26 genera from 14 subfamilies and 08 families. A few species like Acrida exaltata, Trilophida annualata, Aiolopus thalassimmus tamulus, Hieroglyphus banian, Oxya velox and sorted out in common north of Himachal Pradesh to deep south up to Bihar and Madhya Pradesh. Perhaps the reason had been that these remain tolerant to change in climatology like monsoon rain, and physiography of soil to lay their eggs in large number. It has been concluded that these phototaxic species are reported from every part of Uttar Pradesh.
