ABSTRACT: Spider mite belongs to the family Tetranychidae that comprise a huge number of different species that attack a wide range of plants. A survey was conducted to gather information about spider mite around the Lake Chad shore area of Nigeria. The aim was to report the status of spider mite on horticultural crops, the amount of loss that is associated with the infestation and to find out the measures being taken by farmers in controlling the pests. A preliminary survey was conducted by visiting and inspecting farms around six villages (Daban masara,Daban giwa,Gapchari,Dumba,Baga and Doro) in the Lake Chad shore area before the focus was centered on Baga and Dumba where the mites are found. Using structured interview method, a sample size of 62 farmers was interviewed around the two villages.

ABSTRACT: Field experiment was carried out during the rabi season of 2013 in the research farm of Uttar Banga Krishi Viswavidyalaya located at Pundibari, Coochbehar, (W.B). The soil of the experimental site was sandy loam in character. Ten treatments under each herbicide were setup with plot size of 2X3 M in maize verity (JKMH-1001). The dose of different herbicides (kg/ha) for the both treatment [Post-emergence application (PPSA) and Pre- emergence application (PE)].

ABSTRACT: Climatic restrictions on vectors, environmental habitats and disease causing agents are important for keeping many animals diseases in check. Alterations of temperature and precipitation regimes may result in a spread of disease and parasites into new regions or produce an increase in the incidence of disease, which, in turn, would reduce animal productivity and possibly increase animal mortality. Some current practices to reduce heat stress in dairy cows, such as shades, sprinklers and ventilation will be suitable for adapting to future climates if the economics of heat stress management do not change radically. However, farmers are not quite aware about the impacts global warming can produce in their operation. Therefore, good research work is needed to help them take strategic and tactical decisions.

Key words: Habitats, precipitation, ventilation, global warming and tactical.

ABSTRACT: Visceral leishmaniasis (VL) is the second largest parasitic killer of human in the world after malaria which is responsible for an estimated 500,000 new cases of VL in each year with 8-10% mortality. The parasite is transmissible to humans and animals by the bite of phlebotomine sand fly. The clinical manifestations are highly diverse, humans and dogs are naturally infected, and the diseases are associated with several risk factors, yet to understand. The aims of this study were to apply traditional and molecular detection tools and more emphasis was given to identify goat as a carrier of visceral leishmaniasis.

ABSTRACT: In the present study, activated carbons of Eichornea crasssipes(EC), Sugarcane bagassae(SB), Tea waste(TW) and Guava leaf(GL) were prepared from agricultural wastes and used as an adsorbents for the removal of Acid Blue 92 (AB92) dye from aqueous solution. The effects of pH, adsorbent dosage, initial dye concentration and contact time on the extent removal of AB92 has been studied by Batch adsorbtion method. The Langmuir and Freundlich isotherm models were applied for the present systems and the Langmuir model was applied to the equilibrium data better. The kinetic data followed the first -order kinetics determined from the Natarajan-Khalaf isotherm, Lagergren isotherm and Bhattacharya Venkobachar isotherm. The intra-particle diffusion was also measured to determine the porousities of the carbons and the boundary effect of the carbons on the adsorption of AB92. Effect of particle size of adsorbents and the thermodynamic parameters of adsorbents can also analysed. The desorption was also studied. From the data GUC has the more relative adsorption capacity and the ECC has the lesser among the above charcoal.

ABSTRACT: The comparative efficiency of methanol extracts of Neem (Azadirachta indica), Bitter Gourd (Momordica charantia) and chemical anthelmintic Albendazole on gastrointestinal nematodes infected goats were evaluated by egg per gram (EPG) count for a period of approximately three weeks. Twelve Kambing Katjang goats naturally infested with gastrointestinal parasite were selected based on EPG count (>300 EPG) and divided into four groups each consisting of three goats. Treatment I was methanol extract of A.indica (0.5 ml/kg body weight), treatment II was methanol extract of M.charantia (1 ml/kg body weight), treatment III was chemical anthelmintic, Albendazole (0.1 ml/kg body weight) and finally treatment IV was control.

ABSTRACT: Cultivation of Pleurotus ostreatus on different saw dust substrates such as Ficus carica (Fig tree, T2), Albizia saman (Rain Tree, T3), Swietenia mahagoni (Mahogany tree, T4), Leucaena leucocephala (Ipil ipil tree, T5), Eucalyptus globulus (Eucalyptus tree, T6) and mixture of all five tree sawdust (T1) supplemented with 30% wheat bran and 1% lime as basal substrates were investigated. The effects of various saw dust substrates comparative growth and yield of performance oyster mushroom were analyzed. The highest mycelium running rate (0.70 cm/day) and the lowest time from primordial initiation to harvest (3.33 days), were obtained in T4.

ABSTRACT: The study was conducted on formulation and preparation of mixed squashes with different combinations of papaya, banana and carrot pulp. The research work was carried out in three phases. In phase I, the moisture content, total soluble solid (TSS), ash, pH, acidity, vitamin C (ascorbic acid), total sugar, reducing and non-reducing sugar of ripe papaya, ripe banana, fully matured carrot and processed mixed squash from these were analyzed. The pulp prepared from papaya, banana and carrot were used for preparation of mixed squash with various combinations along with other ingredients.

ABSTRACT: TEffectiveness of three insecticides, monocrotophos(Azodrin 60EC), Cypermethrin(Cymbush 10EC) and Carbaryl (Vetox 85WP) at specified spray schedule, were evaluated in comparison to untreated control treatment for the management of common upland rice sucking bugs, Aspavia armigera and Stenocoris claviformis. . Cypermethrin at the rate of 15kg a.i./ha was most effective at reducing the population of of the sucking bugs, 24 and 72 hrs after application while carbaryl at 1.5kg a.i./ha was observed to be most effective in producing residual effect on the sucking bugs. Carbaryl at 1.5kg a.i./ha provided better reduction in the population of rice bugs. The application of the selected insecticides did not result in increase in yield of upland rice. Application of insecticides to control sucking bugs in upland rice should strictly be based on damage threshold of the insect pest.
