“…Desa Cigugurgirang merupakan desa yang memiliki sejarah sebagai penghasil jeruk terbaik di kawasan Bandung utara pada tahun 1960-1970 an. Akan tetapi, semua pohon jeruk di kawasan Bandung Utara musnah karena virus citrus vein phloem degeneration (CVPD) pada akhir tahun 1970 an (Beattie & Holford, 2022). Perkebunan jeruk mulai tumbuh lagi sejak 8 tahun terakhir dengan adanya varian baru yang dikembangkan Kementrian pertanian yaitu Jeruk Oranye Parahyangan (JOP).…”

Masalah utama yang dihadapi oleh kelompok tani makmur sedulur di Desa Cigugurgirang dalam proses pengelolaan kebun jeruknya yakni adanya hama jeruk yang sering mengganggu pertumbuhan tanaman jeruk. Selain masalah tersebut, saat ini terdapat kondisi daun jeruk cepat kuning dan belum diketahui secara pasti penyebabnya, salah satu kemungkinannya ada pengaruh kondisi kesehatan tanah. Oleh karena itu, pemantauan kondisi lingkungan di perkebunan jeruk sangat dibutuhkan kelompok tani makmur sedulur. Teknologi pengindraan dan pemantauan lokal di bidang pertanian merupakan salah satu cabang dari smart farming. Pada kegiatan pengabdian kepada masyarakat (PKM) ini pihak Universitas Telkom (Tel-U) melakukan desiminasi produk t-grow yang berfungsi untuk memantau kondisi lingkungan di perkebunan jeruk. Parameter pengindraan pada t-grow berupa pengukuran pH tanah, kelembaban, hidrogen, dan kadar NPK berikut dengan aktuator pengusiran hama dengan frekuensi ultrasonik. Desiminasi produk t-grow ke kelompok Petani Makmur Sadulur dalam bentuk penyuluhan oleh tim dosen dari Tel-U. Berdasarkan hasil evaluasi kegiatan PKM yang dilakukan pihak Tel-U melalui program desiminasi produk hasil penelitian smart farming t-grow kepada kelompok tani makmur sedulur di Desa Cigugurgirang, 100 % mitra sasar setuju dan sangat setuju bahwa kegiatan desiminasi produk t-grow sesuai tujuan PKM. Lebih jauhnya mitra sasar telah memahami pentingnya pemantauan keadaan lingkungan tanaman jeruk sehingga dapat mengatur ulang konsentrasi yang dibutuhkan pada setiap tanaman jeruk.

The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, transmits ‘Candidatus Liberibacter asiaticus’ (CLas), a phloem-limited bacterium associated with the severe Asian form of huanglongbing (HLB), and the most destructive disease of citrus. The pathogen and the psyllid, both of South Asian origin, are now widespread in citrus regions of Asia and the Americas. There is no cure for the disease. Application of synthetic pesticides, in some instances more frequently than fortnightly, to minimise incidence of ACP in citrus orchards, has not prevented inevitable impacts of the disease in regions of Asia where CLas is present. Despite the inevitable spread of the disease, significant progress has been made in Sarawak since the mid-1990s towards effectively implementing integrated pest management (IPM) programs for stemming the impact of the disease and detrimental consequences of over-reliance on synthetic pesticides. Growers are encouraged to plant pathogen-free trees, remove diseased trees, monitor incidence of the psyllid, and to use pesticides judiciously to reduce their detrimental impacts on natural enemies. Knowledge has been enhanced through research on seasonal incidence of the psyllid, use of mineral oils, development of protocols and iodine–starch test kits for detecting infected trees, PCR for confirming the presence of CLas in symptomatic leaves, methods for monitoring incidence the psyllid, and training extension staff and growers. However, major impediments to increasing the average longevity of trees beyond <5 years in poorly managed orchards, based on marcotting (air layering), and >12 years in well-managed orchards, based on pathogen-free trees, still need to be addressed. These include grower knowledge, marcotting, aggressive marketing of synthetic pesticides, high prices of mineral oils, spray application procedures, and better reliance on natural enemies of the psyllid.

Foraging Behaviour and Population Dynamics of Asian Weaver Ants: Assessing Its Potential as Biological Control Agent of the Invasive Bagworms Metisa plana (Lepidoptera: Psychidae) in Oil Palm Plantations

et al. 2022

The bagworm (Metisa plana) is a recurrent indigenous invasive defoliator in oil palm plantations. Moderate foliar injury can cost up to 40% yield loss and more for years. The main objective of this review is to disseminate published research demonstrating the versatile services that would benefit farmers by adopting the Asian weaver ant into their pest management agenda. Oecophylla smaragdina is a natural indigenous enemy applied as a successful biological control agent (BCA) and strong component of integrated pest management (IPM) against important damaging pest infestations of commercial crops in the Asia-Pacific region. Farmers facing invasion could benefit by introducing Oecophylla ants as a treatment. The foraging behavior and population dynamics of this species are poorly documented, and hence need further evaluation. Ants of the Oecophylla genus, while exhibiting an intrinsic obligate arboreal pattern, demonstrate additional lengthy diurnal ground activity. The absolute territorial characteristic via continuous surveillance is significantly valuable to maintain pest balance. The exploratory scheme of major workers over large territories is derived from their inner predation instinct. The insufficient understanding of the population dynamics of this weaver ant species diverges from the knowledge of underground species. However, population density estimations of weaver ants by direct nest visual recordings are practicable and viable. The abundance assessment of individual underground ant species colonies by excavation ends with their extinction, which is not a sustainable model for O. smaragdina. Mathematical model estimation by simulation could not resolve this issue, adding inaccuracy to the deficiency of experimental proof. Thus, long-term monitoring of the population dynamics in real time in the field is compulsory to obtain a valid dataset. Oecophylla colonies, with the criteria of population stability, individual profusion, and permanent daily patrol services, are eligible as a BCA and alternative IPM treatment. The last decades have witnessed the closing of the scientific applied research gap between Asian and African species in favor of O. longinoda with comprehensive novel findings. By introducing Oecophylla ants, two main goals are reached: easing the burden of management costs for injurious insects and ending the practice of applying highly toxic pesticides that are harmful to non-target taxa, thus promoting environmental restoration.
