Studies on the efficacy of ethanolic and water extracts as well as the ashes of the plant parts of Jatropha curcas (L.) and Azadirachta indica (A. Juss) for the control of Anobium punctatum on boards of Alstonia boonei were carried out at the wood work unit of the Michael Okpara University of Agriculture, Umudike. A completely randomized design with three replications was used. Data were collected weekly for one year after application (1 YAA). Result showed that among the plant parts of Jatropha curcas and Azadirachta indica tested, Jatropha Seed and Jatropha Bark, Neem Leaf and Neem Bark were the most effective in controlling the number of boards attacked and number of gallery activities of the insect pest. The least number of pest infestation occurred with ashes of Neem Leaf (4.07) and (29.5) respectively for number of boards attacked and number of galleries on boards, followed by ashes of Neem Bark. All the plant extracts reduced significantly(P>/0.05) the activities of the beetle than the control, which had the highest number of boards of Alstonia boonei attacked as well as the highest number of galleries on boards. Ash treatment however performed better than the other extracts in reducing the activities of the pest. Therefore this study showed that biopesticide extracts from Azadirachta indica and Jatropha curcas could be recommended for further studies.
