POTENSI SERANGGA DI SEKITAR TANAMAN PADI (Oryza sativa L.) PADA AREAL PERSAWAHAN LALETEN KABUPATEN MALAKA

Abstract

Rice field ecosystem is artificial ecosystem. Insects as one of the rice field eccosystem components play a pivotal role in the food chain which is as herbivore, predator and detrivore. This research aims to identify insects in the rice field at Laleten Vilagge. Also potential insects, and factors affecting the insects' activities were investigated. The research was conducted in Malaka Regency, East Nusa Tenggara during March, 2017. The research method was Trap Method using net and lamp. Biological wealth equation was used to assess the potential insects. The results shows that insects in the rice field of Laleten were grouped in three based on their role as predator, herbivore and detrivore. Insects found in the net trap were 8 species, 7 families, and 6 ordos. Insects found in the lamp trap was 1 species, 1 family and 1 ordo. From all the insects, it was identified insect diversity values as followed; 54.26 for predators, 35.12 for herbivore and 30.79 for detrivore. The average of biodiversity value (R) was 120, 17.

Serangga Entomofagus Sebagai Biological Control di Areal Persawahan Fafibola Kabupaten Timor Tengah Utara

“…Serangga musuh alami sebagai biological control memiliki banyak manfaat bagi manusia. Manfaat dari serangga entomofagus secara garis besar dapat digolongkan dalam biological control yang alamiah dan ramah lingkungan, manfaat ekonomis, manfaat untuk penelitian, manfaat rekreasi dan parawisata [4].…”

“…Pengetahuan dan informasi keanekaragaman jenis serangga entomofagus sebagai biological control dan peranannya pada masyarakat sekitar areal persawahan, Kabupaten Fafibola Kabupaten TTU belum tersedia [4]. Kurangnya pengetahuan dan informasi tentang biodiversitas dan potensi serangga serangga entomofagus sebagai biological control sering berdampak pada kegiatan yang mengancam penurunan dan kepunahan biodiversitas serangga -serangga entomofagus yang disebabkan oleh rusaknya ekosistem akibat aktivitas yang tidak bijaksana oleh manusia terhadap lingkungan seperti pengundulan hutan, polusi pestisida dari pertanian dan pencemaran air.…”
