Effect of Soursop Bark Extract (Annona muricata L.) as a Botanical Insecticide on Cockroach (Periplaneta americana L) Mortality

The American cockroach (Periplaneta americana) be an insect which are disease vectors for humans. The control of American cockroaches be often carried out by the community by using synthetic insecticides, however the use of synthetic insecticides can have a negative impact on both humans and the environment. Therefore, natural alternatives are needed that are safer for the environment and humans by using vegetable insecticides. Soursop bark contain active compounds that have potential as vegetable insecticides. This study aim to determine ability of soursop bark extract as vegetable insecticide on mortality of adult American cockroaches, to determine LC50 value of soursop bark extract, and to determine compounds present in soursop stem bark. This research conduct from August 2022 to February 2023. Research this research use experimental method with Completely Randomized Design (CRD) with 5 treatments (control (-), 1%, 3%, 5%, and control (+)) and 5 repetition. Average American cockroach mortality calculate after 24th, 48th, and 72nd hours. Data that obtain analyze using One Way ANOVA. Results show that soursop bark extract be effective as nabatic insecticide against American cockroach mortality with LC50 value of 2.89%. Bioactive compounds that contain in soursop bark extract be alkaloids, flavonoids, saponins, steroids, and tannins
