Collembola Diversity between Chemical Pesticide and Bioinsecticide in Broccoli Farm (Brassica oleraceae var. italica)

Abstract

The existance of Collembola diversity was determined by how land system work. Farming systems with excessive pesticide application can reduce number of Collembola. On the other hand nowaday people aware of environment by using bioinsecticide. The Method were comparing two land system which use Chemical pestisice and Bioinsecticide. Procedure were using Trapping wells (PMS) in three plots; T0: control without treatment, T1: Chemical Insecticide, T2 : Bioinsecticide for 24 hours. The factors that measure are abiotic factors by taking 10 grams of soil planting Broccoli (Brassica oleraceae var Italica), after 24 hours of taking separates it with other land animals, then identifying Collembola species were using Microcam based on identification book of Collembola. The result showed that density and Biodiversity of land system bioinsecticide was the highest value and indic. It was found also that in Broccoli farm dicovered 3 Familia and 8 species of Collembola both litter and soil. Species found that Isotomurus sp, Seira sp, Lepidosira sp, Coecobrya sp, Callyntura sp, Homidia sp, Sallina sp and Ascocytrus sp, three Family is derived from Isotomidae, Entomobryidae and Paronellid.
