Mulberry Defoliators: Distribution and Occurrence from Aurangabad (M.S.), India

Author- Sunil B. Avhad and Chandrashekar J. Hiware

Abstract - A field investigation on the seasonal incidence of frequently occurring leaf eating pests of mulberrywas carried out for two annual cycles from Aurangabad district of Maharashtra state. The presentsurvey was conducted during June 2009 to May 2011. The result shows that, different pests aredamaging the Mulberry cop from the study area which causes heavy economical loss to sericulturefarmers. The pests occurred were leaf roller, Bihar hairy caterpillar, cutworms, Red hairy caterpillar,Jassid / leaf hopper, Southern green stink bug / Pentatomid bug, Tree hoppers, Litchi bug, wasp mothand wingless grasshopper etc. In the present study classification, occurrence and type of damage andsymptoms of the defoliator insect communities was also worked out in the mulberry field fromvarious sites in Aurangabad district of Maharashtra state, India.

Title-Two New Species of the Genus Lytocestus (Caryophyllidea-Lytocestidae) from Freshwater Catfish, Clarias Batrachus Linnaeus(1758)

Author- R.T. Pawar and C.J. Hiware

Abstract - The present paper deals with the two new caryophyllaeid species of the genus Lytocestus viz. L. vyasaei n.sp. and L. purnensis n.sp. from the freshwater catfish Clarias batrachus L. from Marathwada region (M.S.) India. The differentiating characters of L. vyasaei are long, neck absent, head is conical shape, and ovary is bilobed, butterfly shaped. In L. purnensis body is elongated, grass blade like, neck present, and ovary is bilobed, H – shaped each lobe joined each other by ovarian isthmus.

Abstract :This paper deals with avifaunal diversity of Nipani reservoir, Belgaum district, Karnataka. It is a perennial reservoir situated at 16º.23’.54’’N L and 74º.21’, 48’’E L of
Belgaum district of Karnataka State (India). Since no data pertaining to avifauna of this
region is available, it was decided to prepare a checklist of birds. Observations were carried out during the period of February 2010 to January 2012. Visual method was used for counting the birds. The avifauna observed during the study period is discussed in the text. The results revealed that 49 aquatic birds were identified. They were belonging 9 orders and 19 families. Some of them were passage migrant, local migratory and winter visitors. The observed birds grouped into cormorant Herons, Egrets, Ducks, Cranes, Coot, Kingfisher Stork, Wagtail, Sandpiper, Terns and Ibis etc. During winter the maximum birds were observed due to easy accessibility of food
and shelter for migratory birds.

Keywords : Nipani reservoir ,Aquatic avifaunal diversity.

Studies on Biology, morphology and Karyotype of Chironomus stigmaterus Say (chironomidae Diptera) from Aurangabad (M.S.) India

AV Gunjal, RJ Chavan, AM Gaikwad

Abstract : The present communication deals with the studies on morphological and a karyological features of Chironomus stigmaterus from Aurangabad district of Maharashtra. During the present study morphology of fourth instar larva, pupa and adult was explored. A larva of present specimen shows mentum with 12 teeth and caudolateral tubules at posterior abdominal region. Pupa is red in colour and exuviae type. In male the setation of tergites and sternites highly variable in size and numbers. Adult female is larger than of male. Polytene chromosome observed at 2n=8 in number. These are the thummi complex specimens. The chromosome AB and CD are submetacentric, EF with metacentric and chromosome G is telocentric.

Effect of TBTCL on Glycogen Profile in FreshwaterPrawn, Macrobrachium kistnensis.

Kharat, Laxmi ,B. Ghoble, K.B. Shejule and B.C. Ghoble

Abstract: The present study has been undertaken to investigate, the effect of lethal concentrations 0.33 ppm, 0.26 ppm, 0.17 ppm and 0.09 ppm of tributyltin chloride on glycogen content in ovary, hepatopancreas, gill and muscle of a freshwater prawn, Macrobrachium kistnensis for 24, 48, 72 and 96 hours respectively. The disturbance in the glycogen profile is one of the outstanding biochemical lesions due to the action of TBTCl. There is significant decrease in glycogen profiles in ovary, hepatopancreas, gill and muscle after exposed to lethal concentration of TBTCl under stress condition. This might be due to increase in glycogenolysis by increase in phosphorylase enzyme activity and elevation of succinate and pyruate dehydrogenase leading to anaerobic metabolism during anoxic stress condition caused by toxicant.
Keywords: Lethal concentration TBTCl Glycogen Macrobrachium kistnensis.

Relationship between Total Length, Standard Length and Scale Length of Freshwater Fish Labeo rohita

Phulwade Durgesh. N., Gedam Ajit. K. , Sonawane Smita. R.

Abstract : The length weight relationship, total length-standard length relationship and fish length–average total scale length relationship of Labeo rohita were studied during the year 2013-2014 by correlation and regression method. Positive correlation between total length and weight of fish, standard length and total length was observed. Studies on relation between fish length and average total scale length was also found positive.

Keywords : Average total scale length, Labeo rohita, total length, standard length.

Evaluation of Bivalves as Bioindicators of Metal Pollution in Freshwater

Bhalchandra Waykar • Gajanan Deshmukh

Abstract : The fresh water bivalves, Lamellidens corrianus,Lamellidens marginalis, and Indonaia caeruleus were exposed to chronic concentration of arsenic (0.1719 ppm),
cadmium (0.1284 ppm), copper (0.033 ppm), lead (1.50 ppm), mercury (0.0443 ppm) and zinc (1.858 ppm) separately up to 30 days in laboratory. Dry weight of each animal was used to calculate metal concentrations (lg/g) and the metal body burden (lg/individual). It was observed that lead (1235.4 lg/g) and arsenic (37.9 lg/g) concentration were highest in Lamellidens corrianus, zinc (3,032.3 lg/g) was highest in Lamellidens marginalis, while mercury (5.87 lg/g), cadmium (142 lg/g) and copper (826.7 lg/g) was highest in Indonaia caeruleus.
