Soil-transmitted helminthic infection is a common public health challenge of primary school children in resource poor and developing countries like Nigeria. The prevalence of intestinal parasites among 200 school children in Oban was carried out between August and November 2021. The investigation was done at St. Michael's Primary School and Early Child Nursery School. The study adopted a cross-sectional, school based, descriptive study. The participants for the study were selected using a systematic sampling technique. Information collected included age, sex, source of drinking water. Results obtained showed that the overall infection rates were 86.72% (i.e., 111 out of 128pupils examined) in St. Michael's primary school, and 90.28% (1.e., 65 out of 72 children examined) in Early Child Nursery School. The children were infected with various parasites. The prevalence of parasites found were as follows: Ascarislumbricoides (57.03%), Trichuristrichiura (32.03%), Hookworm (54.31%) and Strongyloidesstercoralis (16.41 %) in St. Michael's Primary School, Ascarislumbricoides (63.90%), Trichuristrichiura(43.05%), Hookworm (51.38%) and Strongyloidesstercoralis (47.22%) in Early Child Nursery School. Mixed infection with Ascarislumbricoides, hookworm and Trichuristrichiura was observed in six children. It is presumed that poor standard of personal hygiene; insanitary environment and ignorance among other things contributed to the prevalence of these infections amongst children in the community. This calls for radical control measures aimed at the various intestinal parasites. There is need for health education and legislation if the spread of these infections and severe morbidity in infected individuals especially school children must be prevented. [ABSTRACT FROM AUTHOR]

The present study evaluated the effect of extracts of three spices in control of Callosobruchus subinnotatus (Pic). The experimental design used was completely randomized design (CRD). Ginger, scent leaf and curry leaf were obtained and screened for phytochemical and proximate composition using standard laboratory techniques. The Bambara nut was subjected to three treatments (To, T1, T2 and T3) which were replicated 4 times. To was used as control while the rest were treated with the spices. Results from the study showed that the highest mortality rate was recorded on 100g of Ginger extract having percentage mortality of 93.33% (T3). It was followed by scent leaf with a mortality rate of 43.33% (T1). The result also showed that Ginger powder extract gave the lower mean number of holes (41) and with lower weight loss of 4.9% of nuts amongst the extracts used. Bambara nuts that were not treated with plant spice extracts (To) gave the highest mean number of holes or punctures (211) and the highest weight loss 25.5% of nuts. Conclusion of this study is that the plant extracts were effective at controlling Callosobruchus subinnotatus, though at varying degrees. These biopesticides are part of humans and animals food, often are used as ethno-medicines, and are more environmentally friendly being biodegradable, so all these things recommend to be used in the detriment of chemical pesticides.
