| dc.description.abstract | In Ethiopia, chickpea production was limited due to both biotic and a biotic factors. Biotic factors such as diseases; root diseases and foliar diseases and insect pests mainly Helicoverpa armigera Hübner and C.chinensis (L.). The latter two insect pests were among the major factors affecting chickpea production in Ethiopia. Helicoverpa armigera causes up to 33% pod damage at field and C. chinensis (L.) can causes up to 50% kernel weight losses in Ethiopia .Production constraints, post-harvest loss of chickpea is very high in subsistence farmers’ storage conditions. Callosobruchus chinensis L. attacked chickpea are significantly affected not only in terms of quantitative and qualitative, but also these grains lose their germinating capacity completely. Therefore, this study was aimed to determine the efficacy of locally available botanicals against Callosobruchus chinensis on chickpea grain storage. The study was carried out at , grain and seed quality laboratory, College of Agriculture and Environmental Science, Bahir Dar University. The study was done using at different concentrations Neem (A. indica) seed powder (2.5, 3 and 3.5%) and leaf powder (5, 6 and 7%), Wild oil nut (J. curcas) seed powder (7, 8 and 9 %) and E. globuluss (Labill), leaf powder (7, 8 and 9%) were used. The result showed that using Jatropha seed powder( 9% and 8%,) Neem seed powder (3.5%,2.5% and 3%), Neem leaves powder (7%),Eucalyptus leaves powder(9%),had more than (90% ) adult mortality. Jatropha seed powder (9%) Neem seed powder (3.5 %), Neem leaves powder (7%), and Eucalyptus leaves powder (9 %) Malathion (0.05%) concentrations did not produce f1 progeny. No percentage of grain weight loss was recorded when Chickpea grains treated with jatropha seed powder (9%), Neem seed powder (3.5%) and Malathion (0.05%) (Standard check). An incomplete kill of C. chinensis was observed on Chick pea grain that was treated with Eucalyptus leaves powder (7% and 8%), Jatropha seed powder (8%) and Neem leaves powder (6 and 5%). Hence, these concentrations resulted in lower f1 progeny production, percentage of grain damage, percent of weight loss and low germination percentage compared to control treatment and is recommended for application. However, further investigation is needed to determine the non-target effect and effective rate and frequency of application. | en_US |
