“…[28] noted that the greatest challenge to the environmental health are those of municipal solid waste and human excreta. The negative effect of uncontrolled dumping of wastes in developing countries has been a great threat to public health [29,25]. The composition of the dumpsites in this study agrees with that of Onyido et al, (2009) , where they reported the high frequency of M. domestica.…”

“…The negative effect of uncontrolled dumping of wastes in developing countries has been a great threat to public health [29,25]. The composition of the dumpsites in this study agrees with that of Onyido et al, (2009) , where they reported the high frequency of M. domestica. This indicates the probable endemicity of diseases transmitted by these vectors in the city as the environmental conditions (warm humid climate), etiological sources of infection (faecal materials in the refuse) and human population for the maintenance of infections abound.…”

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.

“…Members of the Aedes stegomyia subgenus are receptacle breeders. They breed in small water containers including tree holes, tin cans, tyres and discarded or broken household utensils (1,11,16). CDC ovitraps consisted essentially of black jam jars that are but mimics of receptacles where the mosquitoes breed.…”

A surveillance study of Aedes Stegomyia mosquitoes in three ecological locations in Enugu Southeastern Nigeria was undertaken between January and December 2006. The study sites were No. 33 Park Avenue Compound GRA, Gmelina forest canopy and Ekulu River banks. Twelve CDC ovitraps were set weekly at each location. Each trap was left for 48 hours before collection. At collection, each paddle was wrapped with a clean duplicating white sheet and later sent to the National Arbovirus and Vectors Research laboratory Enugu, for examination under the microscope for the presence of mosquito eggs. A total of 5,251 mosquitoes made up of four species, (Aedes stegomyia aegypti, A. Stegomyia africanus, A. Stegomyia inteocephalus and A. Stegomyia simpsoni) were collected. A. aegypti were 5,191 mosquitoes (98.86%) and formed the bulk of the collection. Mosquito yields from the three ecological locations were 3,186(60.67%) from No.33 Park Avenue, 927 (17.65%) from the Gmelina forest and 1,138 (21.67%) from Ekulu River banks. In all the locations, the mean number of mosquitoes collected, the number of egg-positive paddles and the mean number of eggs hatching out per paddle were least in hot dry and cold dry periods but were significantly higher in warm humid wet period. Graph plots of monthly mosquito collection revealed high mosquito population peaks between April and June and minor peaks around September and November periods.The public health implications of the findings were discussed, and suggestions for regular monitoring and control of the mosquitoes, and protection of individuals and the public were made.

Radicalization in waste-to-energy systems are on the rise to meet human energy demands. Biogas generation from kitchen wastes is one such scheme, though affected by poor yields and methane levels at low temperatures. In this research, biocatalytic extracts with fermentative properties were hereby assessed on their potential to fasten these processes and increase the biogas yield at ambient temperatures. The variations in kitchen waste substrate anaerobic parameters and elemental composition as well as biogas yields and methane levels were monitored in a 28-day retention period. Three 40-liter batch and unstirred bio-digesters containing biocatalysts Terminalia b., Acanthaceae spp. and a control setup were used. The results indicated rapid saccharification rates in the samples with additives. Terminalia b. additives exhibited high volatile solids hydrolysis rate of 98.3% followed by Acanthaceae spp. (50.8%) and control sample (29.4%). Similar trends were observed in organic carbon reduction as the levels of nitrogen, phosphorus and sulfur linearly increased. The biocatalysts did not affect substrate pH, volatile fatty acids and alkalinity levels. Terminalia b. sample produced 2.32 folds higher while Acanthaceae spp. sample produced 1.375 folds higher than the control sample. Terminalia b. methane levels were highest (45.475±0.922%) followed by the control sample (41.750±1.401) and Acanthaceae spp. sample (39.275±0.263%) after 28-day retention period at 19.5±0.5°C. Use of these biocatalysts in biofuel synthesis can thus optimize biogas production leading to greener economies.
