Abstract

Onion is one of lowland vegetables commodity that has been long cultivated intensively by farmers in Indonesia. Probolinggo is one of the regions which give considerable contribution of producing onion to the national needs. In an effort to increase production, onion farmers in Probolinggo mostly relies on external supply in the form of artificial chemicals (fertilizers and pesticides). However, the using of artificial chemicals can cause pollution and damage the environment. So that utilization of biological agents and organic fertilizers which are environmentally friendly can become other solutions to increase the yield of onion production. Based on this case, it is very important in efforts to increase production of onion by combining organic fertilizers to enrich the content of organic matter in the soil with biological agents in tackling pests attack. Based on the research results in application of combining organic fertilizers granules plus NEP and biological agents Heterorhabditis sp. in District Gending Probolinggo shows that : 1. reducing the population of pests Spodoptera exigua up to 72.260%. 2. improving onion plant growth more optimal. From the result, it shows that the combination of organic fertilizer granule plus biological agents and NEP Heterorhabditis sp. (P2A1) is more effective than the combination of the others. Keywords: onion, biological agents, spodoptera exigua

Abstract

The exploration of the butterfly on The University of Jember has been conducted. The objective of this study is to explore the diversity of butterfly on UPT Agrotechno Park The University of Jember. The research has been done during August to September 2020. Sampling was carried out by scanning methods in the fields with sweeping net. The results revealed the existence of 18 genus with four belonging to the families Papilionidae, Pieridae, Nymphalidae, and Lycaenidae. Moreover 24 species had been identified namely Papilio sp. 1, Papilio sp. 2, Troides sp., Graphium sp., Appias sp., Catopsilia sp., Delias sp. 1, Delias sp. 2, Eurema sp.1, Eurema sp. 2, Leptosia sp., Euthalia sp. 1, Euthlia sp. 2, Dophla sp., Elymnias sp., Euploea sp. 1, Euploea sp. 2, Hypolimnas sp., Junonia sp. 1, Junonia sp 2, Discophora sp., Acraea sp., Zizina sp. dan Lampides sp. Butterflies use plants as host plants and food plants. High host plant diversity is directly proportional to the diversity of butterfly species. The UPT Agrotechnopark Universitas Jember has 1 hectare of land in which there are collections of fruit, vegetable, ornamental, medicinal and food plants. The high diversity of host and forage plants in the UPT Agrotechnopark is a good habitat for butterflies. However, identification to the species taxa are further needed.
