( The Potential of Botanical Insecticides to Control of Aphis gossypii on Gerbera and its Compatibility with Menochilus sexmaculatus )   Kutu daun Aphis gossypii diketahui dapat menghambat peningkatan produksi gerbera. Upaya pengendalian hama ini masih mengandalkan penggunaan insektisida sintetik. Namun, pada beberapa kasus, praktik pengendalian hama tersebut seringkali kurang efektif. Insektisida nabati merupakan salah satu teknik pengendalian ramah lingkungan yang dapat mengatasi permasalahan tersebut. Penelitian ini bertujuan menguji keefektifan formulasi insektisida nabati ekstrak daun suren (Toona sinensis) dan bunga piretrum (Chrysanthemum cinerariaefolium) dalam pengendalian A. gossypii pada tanaman gerbera serta kompatibilitasnya dengan Menochilus sexmaculatus. Penelitian dilaksanakan di Kebun Percobaan Balai Penelitian Tanaman Hias dari bulan Februari sampai November 2017. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan 12 perlakuan dan tiga ulangan. Perlakuan ekstrak bunga piretrum dan daun suren serta campuran keduanya (Formula I, Formula II, Formula III) diuji keefektifannya terhadap nimfa A. gossypii pada tanaman gerbera koleksi plasma nutfah nomor 01200002. Pengujian dilakukan pada dua taraf konsentrasi 0,35% dan 0,40% (w/v) dengan metode semprot serangga dan residu pada daun. Uji kompatibilitas insektisida nabati terhadap M. sexmaculatus dilakukan dengan metode semprot serangga. Hasil penelitian menunjukkan bahwa semua perlakuan insektisida nabati memiliki aktivitas insektisida, namun hanya perlakuan konsentrasi 0,40% yang menunjukkan persentase kematian tertinggi hama target. Penyemprotan langsung insektisida nabati pada nimfa A. gossypii lebih efektif dibandingkan dengan residu pada daun gerbera. Perlakuan Formula III 0,40% menunjukkan mortalitas tertinggi, dan keefektifannya setara dengan imidakloprid dalam mengendalikan kutu daun di rumah kaca. Ekstrak insektisida nabati uji kompatibel dengan M. sexmaculatus, sementara imidakloprid bersifat toksik terhadap keduanya. Dengan demikian, penggunaan imidakloprid untuk pengendalian kutu daun pada tanaman gerbera perlu dibatasi.

The botanical insecticide is one of the environmentally-friendly control techniques to overcome this pest. The objective of research was to examine the effectiveness of the botanical insecticide from Toona sinensis leaf and pyrethrum flowers extract to control gerbera aphids and its compatibility with Menochilus sexmaculatus. The research was conducted at Segunung Research Station from February to November 2017, using a Randomized Completed Design with 12 treatments and three replications. Extract of Toona leaf, and pyrethrum flowers, and mixture of both (Formula I, Formula II, Formula III) were tested for its effectiveness against A. gossypii nymphs on gerbera. Testing was arranged at two concentration levels of 0.35% and 0.40% (w/v) by insect spraying and leaf residual methods. The compatibility test against M. sexmaculatus was worked by using the insect spraying method. The results showed that all botanical insecticide had insecticidal activity, but only a concentration of 0.40% showed the highest target pests mortality. Direct spraying of A. gossypii is more effective than residue on the leaf. The Formula III 0.40% showed the highest mortality and equal to imidacloprid for controlling aphids in greenhouses. The botanical insecticide extract was compatible with M. sexmaculatus, while imidacloprid was toxic them both.
