In terms of control, many farmers in Indonesia are still using synthetic insecticides that are not environmentally friendly, so </em><em>intoxicating yam (Dioscorea hispida </em>Dennts<em>)</em><em> and </em><em>tropical whiteweed (Ageratum conyzoides </em>L<em>.)</em><em> are used as </em><em>botanical insecticide</em><em> that are environmentally friendly. The </em><em>objective</em><em> of this </em><em>research is</em><em> to determine the effect of </em><em>botanical</em><em> insecticide </em><em>that made of</em><em> intoxicating yam </em><em>extract, tropical whiteweed extract</em><em>, and mixed</em><em> extract of intoxicating yam and tropical whiteweed</em><em> on the mortality of cocoa pod sucking pests. This research was carried out from November 2020 to February 2021, at the Plant Laboratory II </em><em>Estate Crop </em><em>Department, </em><em>Politeknik Negeri Lampung</em><em>. </em><em>The research</em><em> used a Randomized Block Design (R</em><em>BD</em><em>) consisting of </em><em>four</em><em> treatments</em><em>, namely: </em><em>P</em><em><sub>0</sub></em><em> (</em><em>c</em><em>ontrol), P</em><em><sub>1</sub></em><em> (intoxicating yam extract), P</em><em><sub>2</sub></em><em> (</em><em>tropical whiteweed </em><em>extract), and P</em><em><sub>3</sub></em><em> (combination of </em><em>both </em><em>extracts</em><em>), </em><em>which were repeated </em><em>six</em><em> time</em><em>s.</em><em> The highest mortality of cocoa pod sucking pests was found in treatment P</em><em><sub>1</sub></em><em> (</em><em>72.73%</em><em>)</em><em>. The </em><em>mortality</em><em> of </em><em>cocoa pod sucking pest </em><em>was caused by extract of </em><em>intoxicating yam </em><em>which contains the active ingredients of saponins, alkaloids, flavonoids, and cyanide which enter the digestive system of the cocoa pod sucking pest as stomach poisons, resulting in the death of the cocoa pod sucking pest</em><em>.</em><em> Based on the results of the </em><em>research</em><em>, it was concluded that </em><em>intoxicating yam extract is the most potential as botanical insectiside for </em><em>cocoa pod sucking pest.</em></p> ER -
