This study aims to monitor and determine the level of resistance of N. lugens to fenobucarb and imidacloprid, to analyse of the specific activities of asetylcholinesterase, Glutation S-Transferase, esterase, and to determine sensitivity of resistant N. lugens to the neem oil. Resistance tests were conducted on a field population from Cipunagara, Subang, West Java, Indonesia, and a standard population originating from Banyuwangi, East Java, that was obtained from the Indonesian Center for Rice Research. Synthetic and neem Insecticides were applied using the leaf-stem dipping method. The resistance ratio obtained by comparing the LC50 value of the field population with the standard. The test insects were considered to be resistant to synthetic insecticide if they had a resistance ratio (RR) of more than 4, indicated resistance if RR ≥1, and susceptible to neem if has RR <1. The results of the research showed that the N. lugens population of Cipunagara indicated resistance to fenobucarb (RR = 2.43), while it was clearly resistance to imidacloprid (RR = 13.95). Specific activities of the acetylcholinesterase and Glutathione S-Transferase of the N. lugens Cipunagara populations were higher than the standard, while the esterase specific activity was lower. These two enzymes are responsible for the resistance of N. lugens to fenobucarb and imidacloprid. Nevertheless, the N. lugens population of Cipunagara was susceptible to neem (RR <1) that never been reported before. Therefore, it is important to know the change in the sensitivity of the target and the metabolic pathway of the insecticide used to manage insect resistance.

An important pest in corn plantation recently reported in Indonesia was Spodoptera frugiperda, a polyphagous pest that have a fast spread rate and caused high damage on young corn. One control that able to use is botanical insecticide. This experiment aims to determine the toxicity of neem, jatropha, clove, and citronella oil (concentrations of 0.1% and 0.05%) against S. frugiferda in corn. Tests carried out using the feeding assay or residue on corn leaves (size 5 x 5 cm). Then, the leaf treatment was given to 10 larvae of S. frugiferda (instars 2) for 48 hours. After that, the feed replaced with untreated feed. The test results showed that concentration neem oil of 0.1% caused the highest mortality of S. frugiferda. Neem oil exposure is also able to inhibit the time of larval development, reduce the percentage of feed consumption, and the weight of pupa the S. frugiferda. Other vegetable oils exposure gave lower mortality in the test insects and some treatments were not significantly different from the controls on the parameters of larval development, pupae weight, and percentage of feed consumption. Neem oils showed strong toxicity against S. frugiperda larvae with Lethal Concentration 50 (LC50) of 0.079 % (CI (95%) 0.066 – 0.095%) and LC95 of 0.338% (CI (95%) 0.024-0.567%).

Penelitian ini bertujuan untuk mengetahui pengaruh ukuran partikel mineral kaolin terhadap mortalitas, pertumbuhan dan perkembangan larva S. frugiperda. Metode penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 7 perlakuan dan 4 ulangan. Perlakuan terdiri atas formulasi mineral kaolin konsentrasi 4% dengan ukuran saringan 100, 200, 300, 400, dan 500 mesh; kontrol air; dan kontrol wetting agent+dispersant agent. Hasil penelitian menunjukkan bahwa ukuran partikel mineral kaolin berpengaruh terhadap mortalitas, lama perkembangan, berat pupa, dan kemunculan imago S. frugiperda. Mineral kaolin ukuran partikel 500 mesh menghasilkan mortalitas larva S. frugiperda (28,75%) yang berbeda nyata dengan kontrol (0,00%) pada 48 jam setelah perlakuan. Sementara itu, pada pengamatan 23 hari setelah perlakuan, semua ukuran partikel mineral kaolin yang diuji menyebabkan mortalitas larva S. frugiperda sebesar 31,25-51,25%; yang berbeda nyata dengan kontrol (0,00%). Perlakuan mineral kaolin 500 mesh menghasilkan total perkembangan larva dan pupa yang terlama yaitu 22,25 hari; berat pupa paling rendah yaitu 0,1506 g serta kemunculan imago normal yang terendah yaitu 8,00 ekor (dari 20 larva yang diberi perlakuan). Dengan demikian, mineral kaolin pada ukuran 500 mesh dapat diaplikan sebagai bahan pengendali hama S. frugiperda.EFFECT OF KAOLIN PARTICLE SIZE ON MORTALITY, GROWTH, AND DEVELOPMENT OF FALL ARMY WORMThis study aimed to determine the effect of kaolin mineral particle sizes on mortality, growth and develpoment of S. frugiperda larvae. The research method used a Randomized Block Design (RBD) with 7 treatments and 4 replications. The treatments consisted of kaolin mineral formulation concentration of 4% with the particle sizes of 100, 200, 300, 400 dan 500 mesh.Two controls were used namely water and wetting agent+dispersant agent. The results showed that the particle size of the kaolin mineral had an effect on mortality, developmental time, pupal weight and emergence of S. frugiperda adult. Kaolin mineral with a particle size of 500 mesh resulted in mortality of S. frugiperda larvae (28,75%) which was significantly different from the control (0,00%) at 48 hours after treatment. Meanwhile, on observation 23 days after treatment, all tested kaolin mineral particle sizes caused the mortality of S. frugiperda larvae of 31,25-51,25%, which was significantly different from the mortality in control (0,00%). The 500 mesh kaolin mineral treatment resulted in the longest total larval and pupal development (22,25 days), the lowest pupal weight (0,1506 g) and the lowest normal adult emergence (8 of 20 treathed larvae). Thus, the kaolin mineral at a size of 500 mesh can be applied as a pest control material for S. frugiperda.

Chili peppers (Capsicum annuum), in their many varieties, constitute a culturally and economically important horticultural crop in a number of countries. The Indonesian cayenne large red chili (Capsicum annuum var. annuum) is used widely in Indonesia mainly in cooking. There have been reports of increased infestation of large red chili by insect pests, particularly fruit flies. The aim of this study was to investigate the effectiveness of five edible vegetable oils (palm oil, coconut oil, soybean oil, corn oil, and candlenut oil) and one non-edible vegetable oil (neem oil) in reducing landings, oviposition, and infestation by the Oriental fruit fly (Bactrocera dorsalis Hendel) in large red chili fruits. This lab-based experiment entailed exposure of large red chili fruits to 20 mature B. dorsalis females (14–21 days old) inside a 15-l plastic container. Six separate containers each held 10 large red chili fruits with a single oil treatment in each. Prior to exposure, each of the treated and control large red chili fruits was punctured once with a needle in order to create an opening for oviposition. Results indicate that the coconut oil formulation was most effective in preventing damage from B. dorsalis females, and reducing fruit fly landings, oviposition, and infestation.

Penggerek buah kopi (PBKo), Hypothenemus hampei Ferr. adalah salah satu hama utama pada tanaman kopi. Persentase serangan hama PBKo pada buah kopi dapat mencapai 100% jika tidak ada pengendalian. Salah satu teknologi pengendalian hama PBKo yang dapat dilakukan adalah penggunaan ekstrak buah kopi yang terinfestasi hama PBKo sebagai atraktan. Penelitian ini bertujuan untuk mengetahui pengaruh esktrak buah kopi yang terinfestasi sebagai atraktan hama PBKo dan memperoleh konsentrasi ekstrak buah kopi terinfestasi yang paling efektif sebagai atraktan imago hama PBKo. Selain itu juga dipelajari serangga arthropoda lain yang tertangkap. Penelitian ini dilakukan di perkebunan kopi rakyat Gunung Tilu, Desa Margamulya, Kecamatan Pangalengan, Kabupaten Bandung, Jawa Barat pada bulan November 2021 hingga Maret 2022. Pembuatan ekstraksi buah kopi terinfestasi dengan menggunakan teknik maserasi dan destilasi air dilakukan di Laboratorium Pestisida dan Toksikologi Lingkungan, sedangkan pengamatan hama dilakukan di Laboratorium Hama Tanaman, Fakultas Pertanian, Universitas Padjadjaran. Penelitian ini menggunakan Rancangan Acak Kelompok dengan 8 perlakuan yaitu P0 = kontrol; P1 = 50 mL air sulingan, P2 = 100 mL air sulingan, P3 = 150 mL air sulingan, P4 = 50 mL ekstrak etanol, P5 = 100 mL ekstrak etanol, P6 = 150 mL ekstrak etanol dan P7 = etanol 10 mL dengan masing-masing perlakuan diulang tiga kali. Hasil penelitian menunjukkan ekstrak buah kopi terinfestasi dengan menggunakan teknik maserasi dan destilasi air tidak dapat menarik hama PBKo serta tidak menurunkan intensitas serangan hama PBKo. Namun, ekstrak buah kopi terinfestasi dapat menarik sejumlah serangga hama dari ordo Diptera famili Drosophilidae dan parasitoid dari ordo Hymenoptera famili Braconidae.
