Abstract
The whitefly Bemisia tabaci (Gennadius, 1889) and the cotton aphids Aphis gossypii are serious pests that are causing damage to the Broccoli (Brassicca oleracea) crop; therefore, this research was conducted to study the effect of the alcohol extract of loquat Eriobotrya japonica at three concentrations 5%, 10% and 15% on the population density of these two pests in a field in Baghdad/Iraq. The total phenol compounds have been detected. The results revealed that the alcohol extract of loquat had an efficient reduction against the whitefly and aphid pests. All the loquat alcohol extract concentrations had the same effects in the reduction of aphid and whitefly density.
