The trap crop technique relies on the attraction of insect pests to plantings other than the main crop. Application using of lemon grass for Habitat modification on paddy field can alter species composition and community structure including Arthropods from insect groups. The lemon grass was planted 20 day before main crop (paddy variety IR 64). This study was conducted in Pasuruan, East Java. Samples were taken using sweep net on vegetative paddy phase, generative paddy phase and ripening paddy phase. Sampling periods from Desember 2012 to March 2013. Each sample was sorted and identified to the family and morphospecies or species. Samples are identified in Zoological laboratory on department of biology, ITS. Study on Arthropoda diversity at different habitats by comparing the species richness is useful for determining ecological indicators at each habitat. The arthropods caught were then classified into some classes: pest (herbivore), natural enemy (parasitoid and predator), and other arthropods. After that, the Species Diversity Index was determined using its Shannon-Wiener Index (H’), Evenness (e), and Species Similarity Index (IS). The compotition of arthropods were classes from herbivore, predator, parasitoid and detritivore. The sum of H’ is higher on paddy field with trap crop application than paddy field without trap crop application. Indicate that a stable relationship could be maintained between rice insect pests and their arthropod natural enemies.Keywords : Habitat modification, Trap crop, Arthropods, compotition, abundance, diversity
