Abstract. Windriyanti W, Rahmadhini N, Fernando I, Kusuma RM. 2023. Arthropods discovered on refugio flowering plants in Mangifera indica plantation. Biodiversitas 24: 4747-4754. The diversity of Refugio flowering plants with different ways of flowering phenology provides alternative food sources for arthropods. Insects are the largest class of arthropods, most of which are ecological services that function as natural enemies and pollinators. Insects require an energy source over a long-term period to promote a stable and healthy population. The use of flowering plants as refugia can maximize the role of insects as ecological services in agroecosystems by providing natural enemies and pollinators with a source of food and shelter. The refugia plants used in this study were sunflowers (Helianthus annuus), king’s salad (Cosmos caudatus), Peruvian zinnia (Zinnia peruviana), Tridax procumbens (Asteraceae), and Alternanthera sessilis (Amaranthaceae) with hedgerow and insectary bank planting patterns. Data collection and periodic direct observation (scan sampling) were conducted by transects. Observed parameters included species composition and population of arthropods in two different agro-systems, monoculture and polyculture. Identification results showed 8 orders, including 44 morphospecies, belonging to 25 families. Arthropod abundance in the on-season of the refugia was found in 1422 individuals. Ecological engineering is a habitat manipulation technology using refugia plants that has increased the composition and population of natural enemy insects and pollinators.

Abstract

Background: Spodoptera litura is a significant pest of crops, causing substantial yield and economic losses. Overreliance on chemical insecticides has led to negative impacts on human health and the environment, as well as the emergence of pest resistance. As a sustainable alternative, Nuclear Polyhedrosis Virus (NPV) has been widely recognized as an effective biological control agent. This study aimed to explore the occurrence of S. litura NPV (Sl-NPV) across multiple regions in East Java Province, Indonesia. Methodology: Field surveys were conducted on maize and tobacco plants in 11 regions, including Mojokerto City, Mojokerto Regency, Jombang, Sidoarjo, Batu City, Malang, Lamongan, Kediri, Blitar, Pamekasan, and Bangkalan. Pathogenicity was evaluated using Koch’s postulate through spray applications on second-instar S. litura larvae. This study employed isolation of NPV from naturally infected S. litura larvae showing typical NPV infection symptoms. Findings: The exploration successfully identified Sl-NPV in Pamekasan and Blitar. Pathogenicity tests revealed that the isolate from Pamekasan was capable of inducing mortality in healthy larvae, whereas the isolate from Blitar did not produce infection symptoms when applied. These results highlight variability in pathogenic potential among isolates. Contribution: The findings provide important insights for the development of local Sl-NPV isolates as environmentally friendly biopesticides to support sustainable pest management in Indonesia.

Abstract

Wereng mangga (Idioscopus spp.) merupakan salah satu hama penting yang dapat mengganggu pertumbuhan dan produktivitas tanaman mangga, terutama pada fase pembungaan. Informasi mengenai spesies, populasi, dan tingkat serangan wereng pada mangga Gadung Klonal 21 di Kabupaten Pasuruan masih terbatas. Penelitian ini bertujuan mengidentifikasi spesies wereng mangga, gejala serangan, populasi, dan persentase serangan pada mangga Gadung Klonal 21. Penelitian menggunakan metode deskriptif dengan pengamatan lapangan dan identifikasi morfologi. Hasil penelitian menunjukkan bahwa di lahan pertanaman mangga Gadung Klonal 21 Desa Oro–Oro Ombo Wetan, Kabupaten Pasuruan ditemukan dua spesies wereng mangga, yaitu Idioscopus nitidulus dan Idioscopus clypealis, dengan dominasi tertinggi pada I. nitidulus sebanyak 548 individu dibandingkan I. clypealis sebanyak 13 individu. Serangan wereng ditandai dengan munculnya embun jelaga, bunga mengering, dan kerusakan malai akibat produksi honeydew yang memicu pertumbuhan jamur embun jelaga (sooty mold). Persentase serangan dan populasi wereng meningkat pada minggu awal hingga pertengahan pengamatan karena melimpahnya tunas muda dan fase pembungaan yang mendukung perkembangan hama.
