Agricultural research in Nigeria: the roles of institutional libraries
(Bowker,part of reed business information ltd. Windsor court, east grinstead house east grinstead, west sussex RH19 1XA,UK, 2001-06) Ekpenyong, G. D.
Investigates the problems of agricultural research libraries vis-à-vis their effects on the advancement of agricultural research in Nigeria. Proffers solutions in the form of modern electronic information facilities like electronic networking, e-mail and internet access. A method of working is suggested in which research institutes and universities in southwest Nigeria can each selectively develop a database information system on agricultural research, all of which are coordinated through a local area network. This will facilities access to information possessed by other such institutions. The advantages of the model are numberous: reduction of the cost information acquisition, reduction in the duplication of reserch efforts and greater productivity by agricultural research scientist.
Automating a large library in Nigeria: the story so far
(1997) Ekpenyong, G. D.
The University of Ibadan library is the first largest library to automate its library services in Nigeria. It is now a focal point for library automation in the country. Highlights the span of library automation in this library and also reflects the impact of the world bank book project started in 1991 in research and teaching in the university.

Computer technology and information retrieval in Nigeria
(Journal of the African society for the psychological study of social issues, 1994-09) Ekpenyong, G. D.
Computer technology, though still advancing in developed countries, is still in its infancy in Nigeria. The benefits of this technology are highlighted and its potential as a fast and easy way of communication globally is undiputed. How can Nigeria benefit from this technology? Some of the problems of introducing this new technology and actually making it work are discussed.
The effect of climate on the seasonal activity and abundance of Amblyomma Variegatumn (fabricus,1794) (acarina:ixodidae)
(University of Ibadan, 1996) Ekpenyong, G. D.
Amblyomma variegatum (fabricus,1794) (acarina:Ixodidae) is a tropical tick found in all the ecological sones of Nigeria. It parasitises all livestock, but is most common on cattle of the zebu type. A variegatum is a 3-host tick. In Nigeria, cattle are reared in the savannah zone of northern Nigeria and only brought down to the south (forest zone) where Ibadan is located, to be slaughtered for food. Cattle are not reared in the south becuase of the adverse effect of Glossina sp. on them. In Ibadan there is only one rainy season per year and this period coincides with the high incidence of A. variegatum adult females on trade cattle during the rains. In this study, it was observed that climatic factors such as rainfall, temperature, humidity and sunshine affect the seasonal appearance of the adults, larvae and nymphs of A. variegatum on trade cattle.

The effect of flooding and sodium chloride on the development of Amblyomma Variegatum (Fabricius, 1794) (Acarina: Ixodidae)
(Acarologia, 1993) Ekpenyong, G. D.
The effect of flooding in water and sodium chloride were investigated to establish ecological factors that limit the widespread distribution of Amblyomma variegatum in some localities. Sample of replete adults, eggs, and larvae of A. variegatum were immersed in 500ml of water for different durations (3, 6, 12, 24, 48, 72 and 96h), then dried and incubated at 25 °C, 85% RH. A second batch was immersed in 500ml of different sodium chloride concentrations (0, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) for periods as stated earlier and thereafter incubated. They were observed for preoviposition time, ovipositional pattern and time of egg eclosion. Result showed that replete females died only after 24 h flooding in water. Eggs were most resistant to flooding. Replete females and larvae were more tolerant to NaCl solution than the eggs.
The effect of humidity on the reproduction of Amblyomma variegatum (Fabricus, 1794) (Acarina: Ixodidae)
(Acarologia, 1991) Ekpenyong, G. D.; Akinboade, O. A.
The effect of humidity on the reproduction of Amblyomma variegatum (fabricus,1794) (acarina:ixodidae) was studied using different humidity ranges at constant tempreture of 25 °C
Experimental Infestation of rabbits with Amblyomma Variegatum larvae:host effects on larval yield, engorged weight and engorgement period.
(1990) Ekpenyong, G. D.
Rabbits infested Amblyomma variegatum larvae were not able to acguire a resistance which effectively inhibited their feeding. There was no significant diiference in "larval yeild",engrogement period of the larvae harvested from the primary, secondary and tertiary infestations. While enviromental tempreture had a marked influence on the "larval yeild", engorged weight and engorgement period of the larvae, the sex of the rabbits did not affect them.
Faculty status for Nigerian university librarians: the Ibadan university case
(University of Ibadan, 1980-12) Ekpenyong, G. D.
The fight for faculty status by university librarians has been on for more than a century and is still being debated the world over today. The writer outlines the meaning of faculty status and how it affects university librarians in developing country- Nigeria. Suggested solutions to this problem are made including the recognisation of the Ibadan university library step-up to reflect a faculty with corresponding faculty titles and ranks.
Festivals in Nigeria: a bibliography
(The department of culture, Federal Ministry of Youth, sports and culture, P.M. B 12524, Lagos, 1981) Ekpenyong, G. D.
or national awareness for the revival of our cultural heritage. It is hoped that Nigerians and aliens resident in Nigeria, researchers in African studies, would find this publication a guide to a better knowledge of the cultural heritage and diversity of the peoples of Nigeira. It is necessary to emphasise, however that although this is a pioneering effort to record all the known and unknown traditional festivals held annually or in some cases, after a long interval of time, this bibliography is by no means exhaustive.
Laboratory studies of the life cycle and behaviour of Amblyomma Variegatum (Fabricus,1794) (Acarina:ixodidae)
(1990) Ekpenyong, G. D.
Amblyomma variegatum is a 3-host tick parasitising livestock in Nigeria. It is of great economic importance because it is a known vector of disease-causing microorganisms, such as Dermatophilus congolensis, Theileria mutans and cowdria ruminatium. It has a long life cycle which in the laboratory at 25 °C and the relative humidity of 85% lasts 160-200 days. It was observed that the longest developmental period occurred at the egg stage(eggs are laid on the ground). This makes this stage the most vulnerable, considering that they are the ones more exposed to climatic and enviromental hazards.
Marketing and promotion of information services in the university of Ibadan library
(Sage, 2003) Ekpenyong, G. D.
Lack of an effective marketing strategy of library resources has been found to be the main reason why target users- university teachers, researchers and students- are not using the Kenneth Dike library of the university of Ibadan as they should. It was found that less than a quarter of these targeted user register annually in the library. A more aggressive marketing strategy has been set in place to sensitize users to the wealth of information resources available in this great library.
Prospects for new information technology in Nigerian libraries

Studies on bacterial association with Amblyomma variegatum (Fabricius, 1974) (Acarina: Ixodidae)
(University of Ibadan, 1990) Ekpenyong, G. D.; Akinboade, O. A.
Amblyomma variegatum, a haematophagus estoparasitic arthropod, is a known vector of several protozoan, bacterial, rickettsial and viral parasites of livestock. Being a 3-host tick , the larvae, nymphs and adults are active in transmitting these microorganisms. In this study, four bacteria Staphylococcus pyogenes, Enterobacter alvei, Escherichia coli and Klesbsiella rhinoscleromatis were isolated from the haemolymph of A variegatum detached from trade cattle. Staphylococcus pyogenes and Klebsiella rhinoscleromatis were found in the egg and larval extracts. It was observed that these two bacteria are transmitted transovarially by A. variegatum.
