Predators and Parasitoids on Ricefield of Back Swamp and Tidal SwampLands in South Kalimantan

Helda Orbani Rosa [2] | Mariana [10]

Abstract: The objective of this study was to find out the species richness and the dominance of natural enemies (predators and parasitoids) on back swamp and tidal swamp lands in South Kalimantan in two cropping systems, using a survey method. The survey took place from April to September 2012. The equipment used to sample the predators and parasitoids was insect net, yellow trap and light trap. Species richness (R) and dominance index (C) from each cropping system were counted. Twenty two species of predators were found, which were included in family of Formicidae, Staphylinidae, Coccinellidae, Coenagrionidae, Lycosidae, Araneidae, Tetragnathidae, Thomisidae, Oxyopidae, Microphysidae, Miridae, Gerydae, Gryllidae, Tettigoniidae and 14 species of parasitoids included in family of Chalcidoidea, Bethylidae, Braconidae, Ichneumonidae, Eulopidae, Vespidae, Diapriidaae, Pteromalidae, Platygastroidea, Pipunculidae, Lygaeidae. Species richness (R) of predators and parasitoids on local cropping system tended to be higher than on conventional ones in all stages and types of swamplands (back swamp and tidal swamp lands). Dominance index (C) of predators on back swamp land was included in the low category and on tidal swamp land in the medium category, for both cropping systems. Dominance index (C) of parasitoids on back swamp land in local cropping system was included in the low category and in conventional in the medium category. The dominance values of both cropping systems on tidal swamp land were high, dominated by Telenomus rowani (local) and Goniozus nr. Triangulifer (conventional).
