Abstract

Padi merupakan komoditas strategis yang bernilai sosial, politik dan ekonomi, karena merupakan bahan makanan pokok di sebagian besar negara berkembang. Produksi pertanian seringkali terkendala oleh perubahan iklim global, seperti perubahan suhu udara, pola curah hujan, dan meningkatnya permukaan air laut. Perubahan iklim juga berdampak dalam konteks hama dan penyakit tumbuhan. Penelitian ini bertujuan untuk mengetahui komposisi, kelimpahan, keanekaragaman, dan kesamaan komunitas pada lahan pertanian kawasan Paciran Lamongan, dan kawasan Kampus ITS Sukolilo Surabaya, dilakukan sampling dengan menggunakan metode perangkap berupa colour pan traps, dan sweep net. Komposisi, dan kelimpahan serangga herbivora pada kedua lahan pertanian didominasi oleh jenis-jenis serangga dari Famili Acrididae (Orthoptera), Delphacidae (Hemiptera), dan Crambidae (Lepidoptera). Keanekaragaman serangga herbivora pada lahan pertanian kawasan Paciran Lamongan lebih tinggi dibandingkan pada lahan di kawasan Kampus ITS Surabaya, Kesamaan komunitas (CMH) pada kedua lahan pertanian memiliki nilai kemiripan mencapai 0,790. Tingkat kerusakan daun pada lahan pertanian di Paciran Lamongan sebesar 28,79% terutama fase vegetatif hingga generatif, lebih tinggi dibandingkan lahan pertanian di Kampus ITS Surabaya. Intensitas kerusakan daun yang terjadi pada kedua lahan pertanian tergolong kategori berat pada fase vegetatif, dan tergolong sangat berat pada fase generatif. Kelimpahan serangga herbivora menunjukan nilai korelasi positif (+) tidak signifikan (P> 0,05) hanya pada lahan pertanian di Paciran Lamongan, terutama pada fase vegetatif.

Rice is a strategic commodity with social, political, and economic value, as it is a staple food in most developing countries. Agricultural production is often constrained by global climate change, such as changes in air temperature, rainfall patterns, and rising sea levels. Climate change also has an impact in the context of plant pests and diseases. This study aims to determine the composition, abundance, diversity, and community similarity in agricultural land in the Paciran Lamongan area and the ITS Sukolilo Campus area in Surabaya. Sampling was carried out using trapping methods in the form of colour pan traps and sweep nets. The composition and abundance of herbivorous insects in both agricultural lands were dominated by insect species from the families Acrididae (Orthoptera), Delphacidae (Hemiptera), and Crambidae (Lepidoptera). The diversity of herbivorous insects in the agricultural land of the Paciran Lamongan area was higher than in the land of the ITS Campus area in Surabaya. The community similarity (CMH) between the two agricultural lands had a similarity value reaching 0.790. The level of leaf damage in the agricultural land in Paciran Lamongan was 28.79%, especially in the vegetative to generative phases, higher than in the agricultural land at the ITS Campus in Surabaya. The intensity of leaf damage occurring in both agricultural lands was categorized as heavy in the vegetative phase and very heavy in the generative phase. The abundance of herbivorous insects showed a non-significant positive (+) correlation value (P> 0.05) only in the agricultural land in Paciran Lamongan, especially in the vegetative phase.
