“…Tithonia diversifolia is a plant can be used as a vegetable insecticide. T. diversifolia acts as antifeedant and anti-oviposition for whitefly (Susanti et al, 2015) which contains essential oils in the form of α-pinene, σ-pinene, and limonene compounds (Oladipupo et al, 2012). From the assay on the effect of corn volatile compound repellent to B. tabaci, there was no significant difference between volatile compounds which dissolved in n-hexane and ethanol.…”

Bemisia tabaci is one of the red chili pests that plays a role as a Begomovirus vector. This vector can be controlled through Integrated Pest Management (IPM) practices. One of the potential practices is by utilizing corn as a barrier crop to prevent the vector from attacking the main crop. The aim of this research was to examine the repellence activity of the volatile compound obtained from various ages of corn crop against B. tabaci. The volatile compound was collected from the corns at 4 week after planting (WAP), 6 WAP, 8 WAP, 10 WAP, and 12 WAP. Volatile compound capture device was designed with two solvents, i.e. hexane and ethanol, then the volatile compound analyzed by Gas Chromatography Mass Spectrometry (GC-MS). B. tabaci repellency against volatile compound was examined using Y-tube olfactometer. Each treatment was employed with 5 replications. Data were analyzed using ANOVA with 95% and further analyzed by Least Significant Different (LSD). The parameter observed was the total of B. tabaci avoided the volatile compound tested until half of the control olfactometer arm. The results showed that all ages of the corn produced repellent compound and the most optimal were corn aged 12 WAP with repellency rate of 83.72%. GC-MS analysis identified the volatile compound were citronella, limonene, β-phellandrene, β-caryophyllene, 1.8 cineole, farnesol, caryophyllene, and patchouli alcohol.

“…This shows that there is a high antifeedant in synthetic pesticides and the EEN antifeedant effect is still low. Antifeedants work by stimulating specific food-repellent nerves in the form of chemical receptors (chemoreceptors) found in the mouth (mouthpart) [26]. The antifeedant activity of Tithonia extract occurs due to the presence of food-inhibiting compounds that block or disrupt the signals of eating stimuli found in food [27].…”

Spodoptera exigua is a cosmopolitan and polyphagous pest. Botanical pesticides are an alternative technique to control S. exigua. This study aimed to evaluate the effect of an ethyl acetate extract of Nothaphoebe coriacea Kosterm bark (EEN) on the biological activity of S. exigua larvae and to determine the most effective concentration to manage S. exigua. This experiment was arranged on a single factor completely randomized design with the concentration level as a factor. Botanical pesticide formulated from ethyl acetate solvent in maceration extraction. The test was carried out by dipping the leaf mustard into the treatment solution and then feeding it to 10 S. exigua larvae. The result showed the EEN had an 0.5% extract content with bioactive from the alkaloids and tannins groups. Mortality and feeding inhibition showed good responses to the biological activity test. However, the mortality rate test revealed different responses the most effective concentration of EEN was 0.5%. This concentration has a mortality of 92% and kill 3.6 individuals per hour, but has a low feeding inhibition of 72.82%. A botanical pesticide from EEN can be developed to control S. exigua. The LC50 obtained from the application of the EEN to S. exigua larvae was 0.062%. EEN has the potential to be developed as a botanical pesticide.

“…Terdapat beragam cara untuk menanggulangi serangan hama kutu kebul. Diantaranya yaitu dengan penggunaan ekstrak daun tithonia sebagai pestisida nabati (Susanti, Widyastuti & Sulistyo, 2015). Di Sri Lanka, petani menggunakan tanaman penjaga (crop protection) untuk mencegah serangan kutu kebul secara ramah lingkungan (Prasannath, Dharmadasa, Menike, & De Costa, 2020).…”

Hama kutu kebul merupakan salah satu persoalan yang cukup sering terjadi di Kabupaten Gorontalo. Minimnya pengetahuan petani cabai rawit mengenai hama kutu kebul merupakan salah satu sebab banyaknya hama kutu kebul yang menyerang tanaman cabai rawit maupun hortikultura lainnya. Fokus utama kegiatan ini adalah menjawab persoalan kutu kebul pada cabai rawit melalui pemantauan secara partisipatif melalui pendekatan citizen science. Tujuannya adalah untuk meningkatkan skill dan pengetahuan petani mengenai pemantauan, pencegahan, serta pengendalian hama kutu kebul pada cabai rawit. Kegiatan ini menggabungkan dua aspek, dimana aspek pertama adalah kegiatan peningkatan kemampuan petani dalam pemantauan, pencegahan, dan pengendalian hama kutu kebul, dan aspek kedua yaitu pemantauan partisipatif berbasis citizen science. Kegiatan ini terlaksana dalam bentuk pelatihan tiga sesi, dimana sesi-1 yaitu mengenai pengenalan hama kutu kebul termasuk ciri-ciri serta penanggulangannya. Lalu pada sesi-2, yaitu praktek pembuatan dan pemasangan alat perangkap yellow sticky trap, dimana petani mempelajari cara membuat perangkap hama kutu kebul. Kemudian pada sesi-3, peserta belajar mengenai prosedur field work, yakni pengamatan, pencatatan, serta input data. Kegiatan ini memberikan pemahaman kepada petani mengenai pentingnya penggunaan perangkap kuning, serta keterampilan kepada petani agar dapat membuat dan menggunakan perangkap kuning sehingga mengurangi serangan hama. Sebelum kegiatan, petani belum mengetahui bahwa mereka dapat membuat sendiri perangkap sederhana dengan menggunakan bahan yang mudah ditemukan disekitar dan memberikan dampak yang baik bagi tanaman mereka. Setelah kegiatan ini, petani menyadari pentingnya pemantauan hama dan juga memahami cara pembuatan perangkap untuk menanggulangi hama kutu kebul sehingga hasil panen dapat dimaksimalkan.
