  The Tourism industry in Nigeria is a growing one and already governments are underway to support the effective management and promotion of the industry. Several attempts to enhance this development have suffered some drawbacks due to inadequate access to information of tourism facilities, destinations and services. This paper emanates from a project that was carried out at the Department of Computer Science, Federal University of Technology, Akure, Nigeria. It discuses how a Web-based Geographical Information System (GIS) is used for the rendering and analysis of tourism information for the efficient management and promotion of tourism. A typical model of a Web-Enabled GIS for tourism was implemented using the Oyo State, (Nigeria) tourism as a case study.

  The test plants species, namely Crotaria retusa, Hyptis suaveolens, Ricinus communis and Tithonia diversifolia were extracted with water. The extracts were evaluated on Callosobruchus maculatus for mortality, oviposition and adult emergence effects. The long-term protectant ability and viability were also investigated. The results showed that the aqueous extracts from T. diversifolia were most effective on C. maculatus, followed by extract from Ricinus communis. The least potent extracts were those extracted from Crotalaria retusa and Hyptis suaveolens. Also, the extracts considerably reduced oviposition by C. maculatus. Extracts from T. diversifolia and R. communis drastically reduced infestation and subsequence damage of the treated cowpea seeds for a period of three months. Most of the treated seeds germinated after 90 days storage period. The results from this study revealed that aqueous extracts from all the four plants species were effective in controlling cowpea bruchid, C. maculatus and could serve as an alternative to synthetic insecticides for protection of stored cowpea seeds against bruchids.
