Abstract

This research aims to determine the effect of application of liquid and solid dosage of Beauveria bassiana and biocompound fertilizer on species diversity and abundance of predator spiders, paddy ratoon with different ge levels in tidal land. The research was conducted in south sumatera rice production centers in tidal land Desa Mulya Sari Banyuasin district. This research was conducted from March until July 2013. Identification did at laboratory of entomology insect pest and plant pathology department, faculty of agriculture, sriwijaya university. This research is a field experiment on 3 paddy ratoon fields applied by B. Bassiana in different compund. Compound preparations are given in these fields are paddy ratoon applied by liquid and solid dosage of B. Bassiana, paddy ratoon applied by biological compound fertilizer and solid dosage of B. Bassiana, paddy ratoon applied by liquid and solid dosage of B. Bassiana and biological compund fertilizer. The results showed that the type of species and families on the land A land B, and C land spiders are predators that come from families Oxyopidae, Araneidae, Tetragnathidae, Lycosidae, Theridiidae, Clubionidae. According to the amount of direct observation in the field spider predators on land are relatively high because of the good condition in research land, no tillage and without used pesticide. On the on characteristics of the community if the dominance index is high then the index will be low evenness. The abundance of spiders in the canopy is the ultimate predators of spider Araneidae family is 62.5%. The highest relative abundance on the surface of the soil that is 100% family Lycosidae. Diversity of spider species are predators high in the canopy during the 38 days after cutting (hsp) is 1.73. The highest species diversity on the ground that at the time of 3 days after cutting (hsp) is 1.32.
