Abstract

Soybean Glycine max L. Merrill has a strategic position in food security. Soybean varieties are various, such as edamame or commonly called vegetable soybean. The important edamame pest is L. indicata. This pest has a natural enemy in the form of parasitoids that spread at several altitudes. This study aimed to investigate the L. indicata pest population and their parasitoid  in edamame soybean plantations at three different altitudes. In this study conducted at three altitudes namely Purwosari (12 masl), Sebanen (814 masl), and Karangbireuh (1295 masl). At each location consist of one plot (1 Ha) and were  made into 4 sub-plots exchanging 10 x10m. Also, the yellow pan trap was installed at  8–57 Day After Planting to collect L. indicata and parasitoid. The results showed that L. indicata was higher in Purwoasri than in other locations. This is due to environmental factors namely temperature. The parasitoid of L. indicata was found in all locations, namely Braconidae family (parasitoid of larvae). While the the paarasitoid were collected in yellow pan trap in all locations i.e. Pteromalidae, Diapriidae, Eulophidae, Mymaridae and Entomacis sp.

Abstract

The presence of organisms in soil play a pivotal role in the health of a ground ecosystem. Diversity and abundance of soil organisms are mainly influenced by soil characteristics and condition of above-ground habitat. This research aimed to study the diversity of arthropods in topsoil of soybean field and investigate factors that affect the abundance and interaction of dominant arthropods. Field research was conducted in three different locations in Malang District, Indonesia. A sampling of arthropods was focused in the topsoil of soybean fields in the soil surface and below-ground. Results found that three dominant taxa of arthropods in the topsoil of soybean field i.e. collembolan, ants, and mites. Different location of soybean field did not affect the species richness and abundance of the dominant arthropods, except the ant abundance. In contrast, soil strata was altered the abundance of collembolan and mites, but not ants. Based on the GLM (generalized linear model), organic matter had a positive relationship with the abundance of collembolan and ants. The abundance of collembolan and ants also had a relationship with mites, yet not vice versa. In conclusion, organic matter in the soybean field supports not only the abundance of arthropod but also their covariation.
