Intermediate snail host of Schistosoma species are known to exist and constitute public health problems in Imo state. Effects on this study were devoted to evaluate the ecology and distribution of the snail hosts of Schistosoma species at the water bodies of Ihitte Uboma local Government area and this was researched during the months of June and September, 2015. A total of 600 pulmonate or lunged snails were collected using scoop net technique from different water bodies in five villages, out of these, 345 (57.5%) were dissected and screened for cercariae of human Schistosomes 67 (19.4%) tested positive. The snail infected were Bulinus  species 55 (82.1%) and Biomphalaria Pfeifferi (17.9%), out of the Bulinus species, Bulinus globosus recorded the widest ecological range, highest  distribution and infection rate of 44.8% followed by Bulinus truncatus (22.4%). The other two genera Lymnaea spp and Melanoides spp encountered in the study did not test positive for cercariae. Environmental modifications such as water resources development schemes in the area are some of the ecological and epidemiological risk factor promoting the spread of the snails. Statistically, presence of urinary and intestinal Schistosomiasis becomes indicated in Ihitte Uboma L.G.A. Regular and timing mollusciciding, malacological and public health education are therefore recommended and imperative.

Different seeds are dispersed from infested to uninfested areas possibly due to several biotic and abiotic mechanisms, and this spread of seed aids the invasion process across the landscape. Currently, in District Charsadda KP, Pakistan, there are about thousands of motorized vehicles, each capable of carrying infested seeds and therefore spreading crop seeds and plant seeds. Studies were conducted in 2019 to investigate the role of the utility vehicles in the dispersal of seeds in District Charsadda. A large number of seeds were found on vehicles. In the current study undertaken in KP, the maximum number of species from the family Apiaceae (3.00), Poaceae (3.00) and Solanaceae (3.00) were found dominant on the vehicles. Whereas, the minimum species number from the family Asteraceae (1.00), Fabaceae (1.00), Ebenaceae (1.00), Umbelliferae (1.00) and Cucurbitaceae (1.00) were associated with the vehicle. These seeds were found on several parts of the vehicles and were contained within mud or dust that had presumably transferred to the vehicle as it undertook its routine activities. The early implications from this present study is that utility vehicles are capable of collecting, carrying, and presumably distributing large numbers of seeds that seed is carried on many parts of the vehicle. Thus, any washing or cleaning procedure used to remove seeds from vehicles will need to concentrate on all parts of the vehicle. Cleaning vehicles at appropriate places should be seen as a possible way to reduce seed spread by utility vehicles.
