| Abstract: | High numbers of Harmonia axyridis adults were observed even when aphid populations were low or absent in kenaf (Hibiscus cannabinus) fields. Compared to a control group given access to water alone or cotton aphids and water, longevity of H. axyridis adults provided with kenaf leaves containing extrafloral nectar significantly increased. |
