Identification of Soil Arthropods on The Allium Fistulosum Fields

Abstract

Agricultural land is one of the factors of biodiversity. Biodiversity (biodiversity) is all types of plants, animals, and microorganisms that exist and interact in an ecosystem that greatly determines the level of agricultural productivity. In general, the soil serves as a place of life, a place of defense, and a source of food for soil organisms. Soil macrofauna can improve the physical, chemical and biological properties of the soil, its presence is influenced by vegetation diversity.  The purpose of the study was to identify soil fauna communities active at ground level and their relationship to soil physico-chemical factors on leek fields. This research was carried out on leek land owned by local farmers located in Pinang District, Tangerang City, Banten using the pitfall trap method. Pit fall traps are used to collect soil insects that are above ground level, carried out for 24 hours on leek fields. The results showed that there are 2 classes, namely Insecta and Arachnida and 4 orders, namely Orthoptera, Spodoptera, Arachnida, and Hymmenoptera from the Phylum Arthropoda. The presence of soil arthropods obtained indicates the presence of low diversity based on Shannon's Diversity Index. Ant populations are found predominantly on leek cropland which are a class of Insecta class, order Hymmenoptera of 112. This is because ants act as polyphagous predators, namely having many types of food, so their existence does not only depend on one source of food.
