A parasitological study was carried out between May and June 2025, to determine the helminth parasites of Agama agama at the Internally Displaced Persons (IDP) Camp located at Uhogua Community, Ovia North-East Local Government Area of Edo State. The lizards were killed by exposure to chloroform, dissected and examined for helminth parasites. A total of 30 lizards were sampled and they were all infected, giving an overall prevalence of 100% and a mean intensity of 24.3 parasites/infected host. The parasites recovered included two nematode species, one species of cestode and a trematode. The nematodes were Strongyluris brevicaudata
and Thelandros scleratus, which were recovered from the large intestine/rectum and a few in the small intestine. The cestode species was Oochoristica sp. recovered from the small intestine and Mesocoelium monodi represented the trematodes, also from the small intestine. The most prevalent parasite was Strongyluris brevicaudata (76.67%), followed by Oochoristica sp. (43.33%) and the least prevalent, Mesocoelium monodi (10.0%). All the parasites recorded infected both male and female lizards, except Mesocoelium monodi, which was only reported in male Agama lizards. The difference in prevalence value amongst the helminth parasites reported was statistically significant (p < 0.05). More samples need to be examined from Uhogua in order to have more materials for proper identification of the Oochoristica sp., as well as to study other parasites that may be present in the study area but were not encountered due to the short duration of this study

Amphibians play vital roles in our ecosystem as both predator and prey, contributing to insect population control and serving as a bio-indicator of the environmental health. This study was done to examine the food and feeding habits of anurans (Sclerophyrs maculata, Hoplobatrachus occipitalis, and Ptychadena pumilio) around the Faculty of Life Science towards the Department of Anatomy at the University of Benin, Edo state, Nigeria. A total of 62 specimen were captured and analyzed using the stomach-flushing method to obtain the stomach content and the prey items were identified. The result revealed that the anurans mainly consumed insects in the Order Hymenoptera, which was the most abundant and frequently occurring prey item (73.43%). Sclerophyrs maculata had the highest dietary diversity, while H. occipitalis showed a preference for Araneae (spiders) and Ptychadena pumilio showed the lowest prey diversity probably due to the number of specimens captured. This study provides insight into the adaptability of these species to their environment, demonstrating their opportunistic feeding habits and the factors influencing their diet. The high consumption of hymenoptera suggests that crawling insects are a readily available and preferred type of food. The presence of empty stomach might indicate low availability of food or fast digestion rate.

Investigation of wall geckos, caught in IDP Uhogua, Benin City, Edo State for their parasites was undertaken between July and September , 2025. A total of 27 specimens were collected consisting of 20 males and seven females. Two species of geckos were encountered, consisting of Hemidactylus angulatus and Hemidactylus mabouia. Out of the 27 samples examined, 17 were H. angulatus and 10 were H. mabouia. Twenty three out of the 27 wall geckos examined were infected with parasites giving an overall prevalence of 85.18%. The parasites recorded included pentastomid;; Raillietiella sp. (55.55%), Cestode; Oochoristica sp. (7.41%), Nematode; Parapharyngodon awokoyai (3.70%) and Thelandros scleratus (62.96%). The most encountered parasite was Thelandros scleratus while the least encountered was Parapharyngodon awokoyai. More males (74.1%) were infected than
Females (25.93%). This difference in prevalence values was statistically significant (p<0.05). The four parasites recorded in this study have previously been recorded by other researchers in Nigeria.Further study needs to be conducted on the helminth parasites of wall geckos from IDP camp Uhogua in order to unravel other species of wall geckos and helminth parasites infecting them which were not recorded in this study due to small sample size and short duration of study. Investigation of two species of wall geckos caught in Uhogua, Benin City, Edo State for their parasites was carried out between July and October, 2025. A total of 32 specimens were collected and all were males. Two species of geckos were encountered, consisting of Hemidactylus angulatus and Hemidactylus mabouia. Out of the 32 samples examined, fifteen were H. angulatus and seventeen were H. mabouia. Nineteen out of the 32 wall geckos examined were infected with parasites given an overall prevalence of 59.38%. The
parasites recorded included; Pentastomid; Raillietiella sp. (37.50%), Cestode; Oochoristica sp.(15.63%), Trematode; Paradistomoides(3.13%) and Nematodes; Parapharyngodon awokoyai (15.63%) and Thelandros scleratus(28.13%). The most encountered parasite was Raillietiella sp. having overall prevalence of 37.50% and mean intensity of 5.67 while the least encountered was Paradistomoides having an overall prevalence of 3.13% and mean intensity of 1.00. The difference in prevalence value was statistically significant (p<0.01). All parasites recorded affected both H. angulatus and H. mabouia except Oochoristica sp.
and Paradistomoides which infected only H. mabouia. The parasites recorded in this study have all been previously reported b other researchers from Uhogua and other localities in Edo State.
