This study was conducted to evaluate the potency of Brucea javanica (melur) for controlling two species ofcrucifer pests, i.e. Crocidolomia pavonana and Plutella xylostella. Melur fruits, twigs, and leaves were extracteddirectly with methanol or sequentially with hexane, ethyl acetate, and methanol. The most active extract was thenfractionated by preparative layer chromatography using hexane, mixtures of ethyl acetate and methanol, andmethanol as eluents. The most active fraction was formulated as EC (emulsifiable concentrate) and WP (wettablepowder) formulations, and tested for their toxicity and antifeedant effect against C. pavonana and P. xylostellalarvae. The results showed that methanol extract of melur fruits was more active than that of twigs and leaves.Fractionation of methanol extract of melur fruits yielded an active fraction which was eluted with ethyl acetate-methanol 9:1. EC and WP formulations of melur fruits were active against C. pavonana larvae with LC50 of 0.39%and 0.21%, respectively. The same formulations were also active against P. xylostella larvae with LC50 of 0.31% and0.54%, respectively. In no-choice tests, the antifeedant effect of the EC formulation on C. pavonana larvae (feedinginhibition [FI]: 70.9%-97.5%) was higher than on P. xylostella larvae (FI: 52.2%-83.9%), but the antifeedant effect ofthe WP formulation on the two species was relatively the same. In a choice test, the EC formulation at LC 85completely inhibited feeding by C. pavonana larvae (FI: 100%).

The purpose of this research was to evaluate the safety of mixture formulations of Tephrosia vogelii and Piper aduncum at various storage temperatures and their insecticidal activity against C. pavonana larvae. Formulations were made from T. vogelii and P. aduncum (1:5) in emulsifiable concentrate (EC) and wettable powder (WP) form. Both formulations have strong insecticidal activity against C. pavonana. This research used a randomized completed design in different temperature treatments. Insecticidal activity of formulations after storage was tested against C. pavonana. The treatments were done using deep leaf method in 5 concentrations and 5 replications. The results showed that LC95 value of EC formulation after storage at condition: below 4°C, room temperature, and 40°C were 0.19%, 0.34% and 0.21% respectively. Based on LC95 value of EC formulation from each treatment, indicated that EC formulation after storage could hold insecticidal activity as good as insecticidal activity before storage due to LC95 value after storage relatively lower than LC95 value before storage (0.35%). In the contrary, WP formulation activity was significantly decreased in all treatments compared to WP formulation activity before storage based on LC95 value.

Petani sangat mengandalkan insektisida sintetik dalam upaya pengendalian hama. Penggunaan insektisida sintetik yang tidak bijaksana dapat menyebabkan kerusakan lingkungan yang ditandai dengan musnahnya mikro organisme tanah, matinya musuh alami, dan matinya organisme bukan sasaran lainnya. Selain itu dampak negatif residu pestisida pada produk pertanian dapat menyebabkan gangguan kesehatan pada manusia yang mengkonsumsi produk yang terkontaminasi residu pestisida. Pengendalian hama alternatif yang ramah lingkungan sangat dibutuhkan dalam proses budidaya tanaman, diantaranya adalah insektisida botani. Upaya mengurangi ketergantungan petani terhadap insektisida sintetik dapat dilakukan dengan menjadikan petani sebagai produsen insektisida dan bukan hanya sebagai konsumen. Insektisida botani dari bahan tumbuhan yang ada di sekitar tempat bercocok tanam dapat digunakan sebagai tindakan pencegahan (preventif) dari serangan hama. Piper aduncum atau yang disebut sirih hutan dan Tephrosia vogelii atau disebut kacang babi banyak ditemukan di lahan pertanian produktif Alahan Panjang, Sumatera Barat. Campuran dua jenis bahan ini dengan perbandingan 2:1 diketahui dapat mengendalikan hama dari golongan Lepidoptera yang menyerang sayuran. Sosialisasi penggunaan di tingkat petani, latihan penyiapan bahan tanaman dan pembuatan larutan semprot dengan konsentrasi 5%, perlu dilakukan agar pengendalian hama efektif dan efisien. Manfaat kegiatan ini dapat membantu petani dalam mengendalikan serangan hama pada tanaman budidaya, mengurangi penggunaan insektisida sintetik, menghemat biaya produksi dan secara tidak langsung meningkatkan pendapatan petani.

Wereng batang coklat atau WBC (Nilaparvata lugens Stal.) merupakan salah satu hama utama pada tanaman padi yang dapat menyebabkan kerusakan dalam waktu relatif singkat. Serangan hama ini mulai mengemuka di Sumatera Barat sejak tahun 2009-2017. Insektisida berbahan aktif buprofezin adalah salah satu insektisida yang banyak digunakan untuk mengendalikan populasi WBC. Pelatihan cara menakar dan aplikasi buprofezin ini telah dilaksanakan di Keltan Rambutan Kelurahan Bungus Barat dan Keltan Sakato Kelurahan Lambung Bukit, Kota Padang. Tujuannya adalah untuk memperlihatkan kepada petani kemampuan insektisida berbahan aktif buprofezin selama 1 jam terhadap 10 ekor WBC yang disediakan. Perlakuannya berupa aplikasi buprofezin pada dosis tertentu (½ dosis anjuran, dosis anjuran, 1½ dosis anjuran), masing-masing dalam 5 ulangan. WBC yang digunakan merupakan populasi lapangan dari lahan persawahan Kecamatan Pauh. Hasil pengujian di Keltan Rambutan menunjukkan bahwa insektisida sesuai dosis anjuran mematikan 20% WBC, dan di Keltan Sakato mematikan 24% WBC, dosis anjuran mematikan 26% WBC dalam satu jam. Dosis anjuran Buprofezin memang tidak ditujukan untuk mematikan 100 % wereng uji, namun lebih kepada dampaknya terhadap penghambatan ganti kulit 2-3 hari kemudian.

The research was conducted at Laboratory of Insect Physiology and Toxicology of Plant Protection Department of Bogor Agricultural University from May to July 2008. Leaves, twigs, barks, and roots of Eurycoma longifolia (Pasak bumi) were extracted with hexane, ethyl acetate, and methanol solvens. The extraction was used single method and level method. Insecticidal activity of each extract has been examined in laboratory to major cabbage pests Crocidolomia pavonana using leaf residual method. Methanol root extract from single method and level method caused 100 and 75.5% mortality of insect test respectively. Hexane and ethyl acetate extracts of leaves, twigs, and barks have low insecticidal activity. The antifeedant effect worked at insect test and varied depends on concentration level. Antifeedant effect also contributed to mortality of larvae along with toxicity of each extract.

The attacks of brown planthopper or BPH (Nilaparvata lugens) in West Sumatra have been recorded since 2012 and continued to increase throughout 2015-2017. Wolf spider (Pardosa pseudoannulata) and lady beetle (Verania lineata) are two predators that can be used as natural enemies. Some research reports that the wolf spider can consume the BPH as much as 5-15 individuals while lady beetles consume as much as 1-11 individuals per day. Training on the use of two predators was carried out in farmer group of Rambutan, Kelurahan Bungus Barat and farmer group of Sakato Kelurahan Lambung Bukit, Padang City. The training aimed to show to farmers the predation rate of both predators against ten individuals of BPH provided. The treatment consisted of the predation rate of both predators (1 individual of wolf spider, 1 individual of lady beetle, 1: 3 composition of the joint predator) in 3 replications. All wolf spiders, lady beetles and BPH used were collected from rice field in Pauh District, Padang City. Within one hour, joint predators in Rambutan were able to consume 53% of the BPH provided, while joint predators in Sakato were able to consume 43%. Some efforts from farmers are needed to protect and conserve the presence of two predators so that they can act as natural enemies in the field.
