Abstract

Palm oil is one of the plantation commodities in Indonesia and had widespread in Indonesia. One of pests that attack oil palm is insect, and the most damaging pests usually from Lepidoptera. The aim of this study was to determine and counting percent parasitization of the parasitoids that parasitize palm leaf-eating pests in the oil palm plantation of PTPN VIII Cindali, Bogor. The study was conducted in 6 blocks of PTPN VIII Cindali oil palm plantation from September 2014 - June 2015 with observations once a month. Sample was taken by means of each block taken 5 plants in every plots randomly to be observed and palm leaf-eating insects taken to kept until the parasitoid was emerged. The outgoing parasitoids then counted and identificated. The results of the study founds 6 species of palm leaf-eating pests and 5 species of Hymenoptera parasitoids that parasitize these pests. Pests that found were Setora nitens, Amatissa sp., Birthosea bisura, Mahasena corbetti, Metisa plana and Pseudococcus sp. Whereas parasitoids that found were Spinaria spinator, Charops bicolor, Telenomus podisi, Aphanogmus sp. and Acerophagus sp.

Abstract

The coconut rhinoceros beetle (Oryctes rhinoceros L.) and brown rhinoceros beetle (Xylotrupes gideon L.) (Coleoptera: Scarabaeidae) are insect pests commonly found in oil palm plantations. Availability of breeding sites is one of factors that can increase the beetle population. Therefore, this study aimed to determine the abundance and age structure of the coconut rhinoceros beetles and brown rhinoceros beetles in the breeding sites located in a plantation with immature and mature stage of oil palms. The results of this study indicated that the abundance of coconut rhinoceros beetle was found to be lower than brown rhinoceros beetle (4.47±13.56 compared to 25.23±16.48 individuals/plot) in the oil palm plantations in PTPN VIII Parakan Salak, Sukabumi Regency. The population of coconut rhinoceros beetle was found in the breeding site located in the plantation with mature oil palms, but not found in the location with immature plants. The age structure of coconut rhinoceros beetle was dominated by the 1st and 2nd instar larvae. The age structures of brown rhinoceros beetles in the breeding sites located in the immature and mature oil palm were similar, and they were dominated by the 1st, 2nd, and 3rd instar larvae. Results of correlation analysis show that there is no correlation between soil chemical characteristics of the breeding site and the beetle population. Soil chemical characteristics at the breeding sites in both locations were relatively similar, and consequently, the abundance and age structure of coconut rhinoceros beetle and brown rhinoceros beetle not significantly different between both locations.
