Studies on the Formosan Plant Seed Oils. XVIII

Developments in plant cell and tissue culture, and in gene manipulation techniques, have provided new tools for generating novel plant phenotypes not attainable solely by traditional selection breeding. Driven by the industrial potential, advances in fundamental plant biotechnology are now being directed to the development of new crops with seed oil compositions targeted towards specific applications. The targets encompass both the edible oil and chemical industries, the latter emphasizing those oils which contain unusual fatty acids with functionalities applicable to specific industrial uses. Traditional concepts of the compositions of plant seed oils must be set aside to embrace a new reality in which a high oleic acid oil can be produced in several current oilseed crops.

Randomized Design

Laboratory experiment was conducted at the Department of Crop Protection Laboratory, Faculty of Agriculture, Bayero University, Kano, in order to assess the effect of oils obtained from the seeds of Jatropha curcas and Moringa oleifera on African Maize Stalk Borer (Busseola fusca Fuller). The effects of the plant seed oils on larvae mortality, pupae and adult emergence were tested on freshly cut leaves/stem of maize 3-4 cm long) and treated with the prepared plant oils at various concentrations (10, 20, and 30%) and control (0%). The experiment was laid out in a completely randomized design and replicated four times. The results showed that both plant seeds oils were lethal to the developmental stages of B. fusca, causing mortality (21%) to the larvae, and subsequently preventing and/or suppressing pupae (2.08) and adult emergence (1.95). Treatment at 30% concentration was found to be more lethal to all the developmental stages of the test insect. Based on the findings of this study, it is recommended that any of the plant seed oils at 30 % concentration could be used to manage B. fusca.
