| Abstract | ||
| Two Field experiments were conducted during 2020 and 2021 summer seasons at the Plant Protection Research Station at Qaha, Qalubiya Governorate, to study the effect of Cinnamon Oil, Lupine oil, (ethyl alcohol, acetone and petroleum ether) extracts from Cinnamon and Lupine plants and Pasha (chemical insecticides) for control the Lima Bean Pod Borer, Etiella zinckenella (Treit.). The concentrations of plant oils and extracts (v/w%) used in this investigation were 2, 1 and 0.5% and were used at the recommended concentrations for Pasha. Cinnamon Oil, Lupine oil, petroleum ether extract from the Cinnamon plant and ethyl alcohol extract from Lupine plant (2%) showed maxima reductions in the larval population and Cinnamon Oil and Lupine oil (2%) after the first and second sprays during 2020 and 2021 summer seasons on cowpea green and dry pods, respectively. Ethyl alcohol extract from the Cinnamon plant (2%) recorded the highest percentage of total protein in cowpea grains (15.51 and 16.75% during the two summer seasons, respectively). Also, the highest yield (green and dry pods) was obtained after treatment by Cinnamon oil (2%) (1775 and 1000 kg/fed.) and (1880 and 1100 kg/fed.) in 2020 and 2021 summer seasons, respectively. Cinnamon Oil and ethyl alcohol extract from Cinnamon plant (2%) used in the field resulted in the highest protection from pests during the storage. Reduction in progeny was 99.16 and 97.97 for Cinnamon Oil and ethyl alcohol extract from Cinnamon plant (2%) in seasons 2020 and 2021, respectively. Hence the efficiency of oils and plant extracts in controlling insects leads to a reduction in the damage caused by insect pests in the field and store. | ||
