Item Efficacy of Lemon Extracts in Controlling Mealy Bugs of Stored Yam (Dioscorea rotundata)(Agricultural Science Digest,, 2023) Adu-Gyamfi, R.; Ankutse, E.; Odonkor, I.; Adu-Acheampong, S.Background: The use of plant extracts in controlling mealy bugs is widespread especially on stored products. Despite this, research on lemon extracts, which is known to be very effective against some insect pests are limited. We assessed the repellent ability of lemon extracts in controlling mealy bug infestation and observed if there was any added benefit of the extract in retarding sprouting of yams in storage. Methods: We used the complete randomized design with three treatments and three replications. The treatments consisted of lemon peels, lemon leaf extracts and a control. Ten tubers of Pona white yam variety were rubbed on the periderm with each treatment and placed on a shelf. Two yam tubers naturally infested with mealy bugs were placed at the edges of each replication to serve as sources of infestation. Result: Results showed that yam tubers treated with lemon peel extracts recorded relatively low mealy bug counts compared to untreated ones and, tubers treated with lemon extracts recorded relatively higher weights compared to those without any treatment. Furthermore, there were no significant differences in neither counted mealy bugs nor yam weight per treatment between extracts from leaves or peels. Lemon extract treatments did not affect sprouting and shelf life of tubers in storage. We conclude that lemon extracts are effective repellents of mealy bugs and can be promoted as a safe bio pesticide for stored yam against mealy bug infestation.Item Migration And Development: A Case Study Of Nkonya Hometown Association On The Development Of Nkonya Ntumda.(University Of Ghana, 2022-01) Odonkor, I.The study seeks to examine the role of Nkonya Hometown association in the development of their community. The study was primarily designed to explore the motivation behind the formation of a hometown association, along with its impacts, as well as the obstacles it faces when interacting with community and local government officials, and to learn about its participation in decision-making processes that affects the beneficiary community. The Nkonya Hometown association is based in Accra. The study employed the theory of social capital as its theoretical foundation to show how the social solidarity mechanisms are interwoven with resources created by associational entities to deliver public good results among communities. The study employed a qualitative research design in exploring how hometown association contributes to the communal development. An interview guide was used as the primary data collection instrument. Twenty-Five (25) respondents were chosen using snowballing sampling. The respondents interviewed includes seven (7) executives of the Nkonya Hometown association, Ten (10) members of the association, and eight (8) opinion leaders and members from the origin community. According to the findings of the research, the association's members benefit from strong social networks that help them maintain and improve their sense of ethnic identity and self-worth. Their members have access to external assets via a bridge network, which aids in the dissemination of knowledge. The research's conclusion is that the local association in this study was not immune to difficulties that impede the pursuit of its purpose and aims, and even its very existence itself.
