Abstract

Leptocorisa acuta.merupakan hama utama pada tanaman padi sawah di Sulawesi Utara. Kerusakan L. acuta menghisap isi malai/gabah menyebabkan gabah menjadi kosong atau hampa. Untuk menekan populasi L. acuta petani masih tergantung pada insektisida, karena belum ada cara lain yang mampu menurunkan populasi hama L. acuta secara nyata.. Tujuan penelitian adalah mempelajari padat populasi hama dan penyebaran cendawan Beauveri bassiana pada hama padi L. acuta di Kabupaten Bolaang Mongondow. Lokasi pengambilan contoh pada tanaman padi hama L. acuta dilakukan di Kecamatan Poigar, Lolayan, dan Dumoga. Manfaat dari Penelitian ini diharapkan dapat memberikan informasi mengenai padat populasi serta penyebaran cendawan Beauveria bassiana. Hasil yang diperoleh menunjukan bahwa padat populasi hama walang sangit L. acuta telah menyebar pada pertanaman padi di tiga Kecamatan Poigar, Lolayan, dan Dumoga. Populasi tertinggi ditemukan pada Kecamatan Poigar yaitu 33 ekor/ 10 kali ayunan kemudian diikuti oleh Kecamatan Dumoga 30.67 ekor/ 10 kali ayunan dan Kecamatan Lolayan 13.67 ekor/ 10 kali ayunan. Untuk penyebaran Cendawan Beauveria bassiana ditemukan pada tiga Kecamatan yaitu Poigar, Lolayan dan Dumoga. _____________________________________________________________________________Kata kunci: Tanaman Padi, Leptocorisa acuta, Beauveria bassiana

Abstract

Ground dwelling arthropods contribute to decomposition, nutrient cycling, and biological control, and their community structure can reflect management intensity in agroecosystems. Intensive vegetable cultivation in Modoinding District, South Minahasa Regency, North Sulawesi, commonly involves routine fertilizer and pesticide use, yet baseline information on soil associated arthropod diversity across major crops remains limited. This study assessed the diversity, functional roles, and population levels of ground dwelling arthropods in vegetable fields using pitfall trapping. Sampling was conducted at ten georeferenced points distributed across key vegetable producing villages, with traps operated for two days and repeated three times. Arthropods were sorted through macroscopic observation and identified using microscopic examination, primarily to order and family levels. Community diversity was quantified using the Shannon Wiener index. Overall, eight orders and seventeen families were recorded, representing decomposers, predators, herbivores, vectors, parasitoids, and omnivores. Decomposer groups, particularly Collembola, were generally dominant in several crop fields, while predator groups such as ants and spiders were also consistently present. Shannon diversity values across host crops ranged from 0.255 to 1.333, indicating low to moderate diversity and suggesting that some fields were characterized by strong dominance of a limited number of taxa. These findings provide baseline data for biomonitoring programs in Modoinding and support the use of ground dwelling arthropod communities as practical indicators to evaluate ecological responses to vegetable production management.
