The six acetone extracts were highly toxic to adult female R. invadens in the combined mode experiment. T. vogelii stem-bark, followed by its seed; A. senegalensis root-bark and T. candida seeds extracts, was most insecticidal to the mealybug. Respective 48-h LD50 values for T. vogelii stem-bark and seed, A. senegalensis root bark, T. vogelii leaf and T.candida seed extracxts were 4.6, 4.6, 11.1, 11.3 and 15.6 µg/insect. Generally, mortalities by each effective extract increased with increase in concentrations. Knowledge of specific mode of action of individual insecticidal extracts of plants is required for developing botanical insecticide for field control of the mealybug pest.</p></div> </div> </div> <div class="block block-layout-builder block-field-blocknodejournalarticlefield-year-of-publication"> <div class="content"> <div class="field field--name-field-year-of-publication field--type-entity-reference field--label-above"> <div class="field__label">Year Of Publication</div> <div class="field__item"><a href="/taxonomy/term/765" hreflang="en">2006</a></div> </div> </div> </div> <div class="block block-layout-builder block-field-blocknodejournalarticlefield-volume"> <div class="content"> <div class="field field--name-field-volume field--type-entity-reference field--label-above"> <div class="field__label">Volume</div> <div class="field__item"><a href="/taxonomy/term/557" hreflang="en">7</a></div> </div> </div> </div> <div class="block block-layout-builder block-field-blocknodejournalarticlefield-page-range"> <div class="content"> <div class="field field--name-field-page-range field--type-range-integer field--label-above"> <div class="field__label">Page Range</div> <div class="field__item">201-207</div> </div> </div> </div> <div class="block block-layout-builder block-field-blocknodejournalarticlefield-authorname-s-"> <div class="content"> <div class="field field--name-field-authorname-s- field--type-entity-reference field--label-above"> <div class="field__label">AuthorName(s)</div> <div class="field__items"> <div class="field__item"><a href="/mu-ukwela" hreflang="en">M.U.
