Fruit flies (Bactrocera spp.) are an important pest for horticultural crops, especially fruits and vegetables. One of the most effective and eco-friendly methods to control male and female fruit flies is by usingtraps that use Methyl Eugenol (ME) block plus fruit essence as an attractant. The purposes of this research were to acquire the most effective formulation of ME Block plus fruit essence to catch the most male and female fruit flies on the chili plantation and to detremine the increase in total of fruit flies caught. This research started from December 2017 to January 2018 at Cibeureum Village, Sukamantri District, Ciamis Regency, West Java Province. The research was conducted using a randomized block design consisting of 8 treatments and 3 repetitions. The treatments consisted of adding fruit essence to the ME block: 2 ml of ME on cotton; 2 ml of ME block; 2 ml of ME block + 4 ml of mango essence; 2 ml of ME block + 4 ml of orange essence; 2 ml of ME block + 4 ml of guava essence; 2 ml of ME block + 4 ml of star fruit essence; 2 ml of ME block + 4 ml of chili essence; Antilat (Organic pesticide) as a comparison. The results showed that ME block plus fruit essence has increased the total of male fruit flies caught, but it did not attract female fruit flies. The best combinations with the highest average of male fruit flies caught were ME block plus orange essence with 750.67/5 week, followed by ME block plus chili essence with 746.00/5 week

Alternaria solani merupakan patogen penyebab penyakit bercak cokelat pada tanaman tomat. A. solani mampu menyerang hampir seluruh bagian tanaman yaitu tangkai, batang, daun, ranting maupun buah tomat. Serangan pada benih dapat menyebabkan benih rebah, bercak atau benih menjadi busuk. Penggunaan pestisida nabati atau ekstrak tanaman untuk mengendalikan penyakit pada beberapa jenis tanaman telah banyak digunakan. Salah satu bahan alam yang dapat digunakan sebagai pestisida nabati ialah tanaman binahong (Anredera cordifolia) yang merupakan tanaman yang populer digunakan sebagai obat tradisional untuk kesehatan maupun sebagai bahan antimikroba. Penelitian ini bertujuan untuk menguji kemampuan ekstrak kasar umbi udara binahong dalam menghambat pertumbuhan koloni jamur A. solani serta menekan kejadian penyakit pada bibit tomat. Penelitian menggunakan Rancangan Acak Lengkap (RAL) yang terdiri atas tujuh perlakuan (konsentrasi ekstrak 0,25%, 0,5%, 1%, 2%, dan 4%; kontrol tanpa ekstrak; dan fungisida propineb 0,3%) yang diulang sebanyak empat kali. Pengujian penghambatan pertumbuhan koloni jamur A. solani dilakukan dengan teknik makanan beracun. Pengujian pada benih dilakukan dengan empat perlakuan dan lima ulangan yang masing-masing terdiri atas 25 benih tomat dengan menggunakan teknik perendaman. Hasil pengujian menunjukkan ekstrak kasar umbi udara binahong 2% mampu menghambat pertumbuhan koloni A. solani sebesar 37,22% dan menekan kejadian penyakit pada bibit tomat dengan penekanan mencapai 83,33%.
