A survey was carried out in Vandeikya Local Government Area of Benue State, Nigeria from April-July 2017 to determine availability of freshwater snails of and their preferred habitats. A total of 289 fresh water snails of four different genera were collected across 27 streams in the 7 districts in Vandeikya LGA. Water pH, water temperature and water velocity were also measured. Lenistislibycuswas found to be the most abundant freshwater snail species accounting for 40.83% of the total freshwater snails. Melanoidestuberculata was the second most abundant accounting for 29.411% of the total snails population sampled, Biomphalaria pfeifferi accounted for 17.99% while Bulinus globosus was significantly lower in abundance than the other snails, accounting for only 11.77%. By location, Mbaduku district had highest abundance of snails 84 (29.1%). The effect of the nature of the substratum on the availability of freshwater snails revealed that habitats with rocky substratum favoured the presence of snails accounting for 181(62.7%) freshwater snail collected.Our understanding of factors affecting the availability and abundance of freshwater snails in nature can prove useful in snail control which is integral for the control of the diseases for which they serve as intermediate host.

Aim: This study was conducted to determine the insect vectors living in refuse dumps at Gombe Metropolis in Gombe State of Nigeria.

Study Design: The metropolis were divided into four longitudinal zones, and in each zone three dumpsites were randomly selected. Visual observations were used to estimate the composition of the refuse dumps.

Place and Duration of Study: The study was conducted in Gombe metropolis of Gombe state between the months of May and August, 2018. 

Methodology: Sweep nets, sticky traps, water traps and handpicking were used to collect different vector species. Specimen collected were preserved and transported to the laboratory for identification. Standard Identification keys were used for the identification of the vectors.  

Results: The compositions of the refuse dumps varied from vegetable matter and animal remains to assorted materials including used tyres, electronic parts, cartons, faecal matter, broken bottles, polythene bags. A total of 464 insect vectors belonging to 9 species were collected. Musca domestica 282(60.8%) was the dominant species, followed by Anopheles spp 55(11.9%) and Aedes species 44(9.4%). Periplaneta americana accounts 37(8.0%) of the collections.

Conclusion: The thriving population of these vector species and the abundance of putrefying refuse dumps are risk factors of the endemic diseases transmitted by such vectors in the city. The present work therefore recommends the proper disposal of refuses to avert an epidemic status.

The therapeutic effects of curcumin and/or dimethyl dimethoxy biphenyl dicarboxylate on rats drinking alcohol were evaluated in the present study. Albino Wister rats drinking 20% ethanol in drinking water were treated with curcumin (100 mg/kg body weight) and /or DDB (50 mg/ kg body weight) mixed in diet for 8 weeks. ALT and AST enzymes were significantly reduced in rat drinking alcohol and treated with DDB or Diferuloylmethane compared with rats drinking alcohol (p<0.05). On the other hand, in case of mixed treatment with curcumin and DDB, AST enzyme was elevated significantly compared with rat drinking alcohol(P<0.05). GGT enzyme was reduced after treatment of alcohol drinking rats with curcumin or DDB in comparing with alcohol drinking rats. MDA concentration in liver homogenate significantly reduced in rats drinking alcohol and treated with DDB compared with rats drinking alcohol (p<0.05). However, serum MDA showed a significant reduction in rats drinking alcohol and treated with curcumin compared with rats drinking alcohol (P<0.05). Histopathological studies revealed liver tissue damage after alcohol administration, however an improvement in liver tissue after treatment with curcumin and DDB. In conclusion, curcumin and DDB can influence and improve the impaired antioxidant defense mechanisms resulted from ethanol and combined treatment with curcumin and DDB has no effects.

Imidacloprid is a termiticide that is slow-acting timber and soil applied but can be transferred in termite workers. The objective of this study was to determine efficacy of imidacloprid to control of termites on sand. Termiticides were tested at Imidacloprid 200 g/L concentrations (2 mL/L, 4 mL/L, 6 mL/L and 8 m/L) were tested. Descriptive analysis presented the mean weight loss for wood blocks under treated sand as follows E. grandis 0.003 (Std: 0.02) and G. robusta 0.013 (Std: 0.04) whereby only woodblocks under treated sand with 2 mL/L were attacked, while the mean weight loss for untreated woods under untreated sand were as follows E. grandis was  0.1 (std: 0.06) and G. robusta was 0.216 (std: 0.147). However, termites attacked all untreated wood blocks regardless of wood species. It was concluded that Imidacloprid at concentration of 4 mL/L serves as the best concentration threshold required in the control of  termites on sand in the management of termites. It was recommended that soil is effective mode of applying imidacloprid termiticide integratedly given that the right concentration levels are utilized.

Five different edible insects from Kaduna, Kebbi, Niger, Sokoto and Zamfara States of North-Western Nigeria, namely; Red Locust (Nomadacris setemfasciata), Desert Locust (Schistocerca gregaria), Variegated Grasshopper (Zonocerus wariegatus), Termite (Macrotermes bellicosus) and Brown Cricket (Gryllotapha Africana), were collected alongside with meats from camel (Camellus dromedaries), Cow (Bos indicus), Ram (Ovis aries), Chicken (Gallus gallus), and Fish (Clariaslazera). The insects were oven dried separately at 60ºC for 3-5hrs while the meats were dried at 60ºC for 48hrs. The dried contents of both the insects and the meats were ground separately and each was subjected to proximate analysis. The results indicated the nutrient to have Carbohydrates ranging between 0.7 g - 12.1 g in the insects and 0.4 g-10.2 g in the meats, Proteins ranging from 12.6 g - 57.3 g in the insects and 18.1 g – 70.4 g in the meats, Fats, Fibre, Ash and Moisture having ranges between 5 g - 17.9 g, 5 g - 20 g, 4g -10 g, 11.5 g - 53.6 g, respectively in insects and 18.4 g - 70.4 g Fats, 5 g Fibre, 2.4 g - 10.4 g Ash and 13.4 g – 59 g moisture in the meats. Equally, the minerals showed varied in both the insects and the meats. Statistical comparison of the means of the results showed that the Carbohydrates, the Protein and the Fibre do not differ (P˂0.0) significantly in both the insects and the meats. Similarly Copper, Iron, Sodium, Calcium, Magnesium and Potassium do not differ significantly in the two groups. This suggested that insects as diet when taken in required amount can meet the protein requirement of the human body and can therefore supplement animal meats in our diets.
