Abstract

Macrotermes gilvus (subterranean termite) can play dual roles as decomposers of natural wood and pest in plantations and urban area. The damages caused by termites in the urban area reaches 35% and in the wood industry can reach 40%. Nowadays, termite control is still carried out by the application of synthetic termiticide. In termites’ case, environmental pollution issue is more important than the resistance of termite to termiticide, so it’s necessary to find alternative termiticide from natural materials. This study examined the potential of clove essential oils to control M. gilvus with two methods. The test methods were oil residue on filter paper and soil in a glass tube H. Clove essential oil on filter paper was applied and dried for one minute, after that put in the petri dish. For soil treatment, the soil was soaked with clove essential oil for one hour and dried for one day, after that the soil treatment put into the bridge tube. Each method was infested by 50 termites with ratio 90% workers and 10% soldiers. Termite mortality on treated filter paper was observed after 72 hours, and on treated soil were observed daily until 7 days. The result showed that clove essential oils caused mortality of M. gilvus more than 90% after consumed and contacted on treated filter paper and contacted on treated soil with concentration 0.80% and 1.20%, respectively. Based on the results, clove essential oil has the potential to be developed and can be used as an alternative against termites, that was environmentally friendly.

Abstract

Stingless bees (Tetragonula laeviceps Smith) play a crucial role as pollinators in agricultural ecosystems, but their populations are increasingly threatened by synthetic insecticide uses. This study aimed to evaluate the effects of five insecticides on T. laeviceps through topical, residual, and oral applications, both individually and in combination with the adjuvant Agristik 400 L (AG). The tested insecticides included indoxacarb, chlorfenapyr, indoxacarb + chlorfenapyr, flupyradifurone, and abamectin + acetamiprid. The results showed that all insecticides caused 100% mortality at the recommended concentrations. Flupyradifurone had the lowest LC50 values (0.35 ppm for topical application, 0.73 ppm for residual, and 0.94 ppm for oral), indicating the highest toxicity compared to other insecticides. The addition of adjuvants significantly increased insecticide toxicity, especially in residual and oral applications. Unwise insecticide use poses a serious risk to pollinator populations and agricultural ecosystems. Therefore, insecticide application should consider plant flowering phases to minimize its impact on bees, and sustainable pest management strategies should be promoted to ensure environmental balance and agricultural productivity.

Abstract

The rice productivity in Gondel Village, Kedungtuban District, Blora Regency, Central Java, has declined. Factors such as attacks by plant pests and diseases (OPT), climate change (DPI) impact, and decreasing soil quality are the leading causes of crop failure. This training aims to enhance the understanding and skills of Gondel Village farmers in making biofertilizers and introducing environmentally friendly pest and disease control methods. The activity involved 40 farmers from 8 farmer groups (Gemah Ripah, Margo Mulyo, Ngudi Makmur, Sido Dadi, Sido Makmur, Tambah Makmur, Tambah Rizki, and Sri Mulyo), with each group represented by five farmers. The training methods included analysis of soil chemicals, socialization, practical propagation of Trichoderma sp. on rice media, and biofertilizer production. Pre-test and post-tests were conducted to assess the improvement in farmers' knowledge. Trichoderma biofertilizer was formulated using carriers such as a) Manure and b) Compost, zeolite, and humic acid. The results of the soil chemical properties analysis showed that farmers' use of chemical fertilizers was very intensive, resulting in very high levels of phosphorus (P) and calcium (Ca) and high levels of potassium (K), magnesium (Mg), and cation exchange capacity (KTK). Evaluation results indicated that the training significantly improved the farmers' knowledge of biofertilizer production in theory and practice. However, some farmers still need further guidance on the propagation of the biological agent Trichoderma sp.

Abstract

The cabbage crop caterpillar, Crocidolomia pavonana, that can be very damaging to Brassicaceae plants in Indonesia, particularly in the Cianjur Regency. Farmers in the area have been using synthetic insecticides like emamectin benzoate to control this pest, but it seems that continuous use of these insecticides can lead to resistance in the pest. This research aimed to determine the level of resistance and distribution of emamectin benzoate in C. pavonana in Cianjur Regency. Field populations of C. pavonana were collected from five villages in three districts in Cianjur Regency. As a comparison, a laboratory population was used to determine the resistance ratio. All populations were tested for toxicity to determine the LC50. The results showed that populations of C. pavonana from Cianjur Regency were still susceptible to emamectin benzoate. Treatment at 22.08 í— 10-4 mg a.i/l concentration in 72 hours after treatment showed that the population's mortality was >90%. The resistance ratios of C. pavonana in Cianjur Regency were quite concerning (resistance indocation), with a range of 1.33–2.01 indicating resistance to emamectin benzoate was moderate. Interestingly, the Sindang Jaya population showed the highest resistance ratio. It's worth noting that over 90% of farmers in the region use this insecticide in the field, which supports the idea of resistance to the chemical. This study provided valuable insight into the distribution of insecticide used and resistance levels of C. pavonana in the area support each other.

Abstract

Nematoda daun Aphelenchoides merupakan salah satu patogen tanaman yang memiliki kisaran inang yang luas dan menyebabkan kehilangan hasil panen. Metode konvensional telah sering digunakan dalam pengendalian nematoda termasuk nematisida kimia, perawatan air panas, dan nematisida hayati tetapi memiliki keterbatasan. Hal ini memerlukan eksplorasi metode alternatif yang ramah lingkungan dan efektif, seperti teknologi gelombang ultrasonik. Penelitian bertujuan mengetahui efektivitas gelombang ultrasonik dalam eliminasi nematoda daun Aphelenchoides pada umbi bawang serta pengaruh pada pertumbuhan umbi bawang. Ekstraksi nematoda menggunakan metode pengabutan (mist chamber) dan perendaman air dingin. Nematoda diidentifikasi berdasarkan karakter morfologi. Umbi bawang merah yang telah diinfestasikan Aphelenchoides diberi perlakuan ultrasonik dengan lama perlakuan selama 26, 30, 37, 44, 60 menit dan kontrol. Umbi bawang yang telah diberi perlakuan ultrasonik ditanam di pot dan diamati parameter pertumbuhannya sampai panen. Data ditabulasikan di Microsoft Excel dan diolah menggunakan SAS JMP. Perlakuan ultrasonik dengan durasi yang lebih dari 37 menit menghasilkan tingkat mortalitas yang tinggi (≥84,00%).  Waktu papar yang berbeda menunjukkan pengaruh yang tidak berbeda nyata dengan kontrol pada tinggi tanaman dan panjang akar. Lebih lanjut, perlakuan ultrasonik dengan durasi yang lebih lama (≥ 37 menit) sangat efektif dalam menekan populasi nematoda Aphelenchoides tanpa memengaruhi pertumbuhan tanaman bawang merah.
