      Abstract

      The purpose of research was to investigate biodiversity, population of bagworm and their parasites in South Sumatera, Indonesia. Survey was conducted in rainy and dry seasons, from October 2008 to August 2009. The method used was purposive sampling method, with ornamental plants grown in home yard, public garden and garden flower’s seller as the targets. The observation was covered: species of bagworm, number of bagworm exist on each ornamental plant, position of bagworm, form of bagworm’s case, level of parasitization of bagworm and information of bagworm’s control. Identification of bagworm species refered to Kalshoven (1981), Mitchell et al. (2001), and related articles about bagworm. Nine species of ornamental plants, i.e. Rose (Rosa sp), Orchid (Dendrabium anosmum), Asoka (Ixora spp.), Bougenvillia (Bougenvillia spectabilis), Hibiscus (Hibiscus rosasinensis), Euphorbia (Euphorbia milli), Palmae (Hyophorbe lagenicaulis ), Roselle (Hibiscus sabdariffa), and Alamanda (Allamanda cathartica) were observed. All plants were grown in home yard, five species (rose, bougenvillia, hibiscus, asoka, palmae, and alamanda) were planted in public parks, and all ornamental plants -except roselle- were found in garden flower’s seller. The species of bagworm associated with those ornamental plants were identified as Pagodiella hekmeyeri Heyl, Clania variegata Sn, Chaliodes kondonis Sn, Oiketicus abotti Templ, Pteroma plagiophles Hps, Mahasena corbetti Tams, dan Clania minuscula Joannis. Population of Pteroma plagiophles was the highest both in rainy and dry seasons. Rose, bougenvillia and alamanda were attacked by three of bagworm species, hibiscus and euphorbia were attacked by four species of bagworm. Orchid, palmae, asoka and roselle were attacked by five species of bagworm. Position of bagworm in ornamental plants varied in parts of the tree such as leaves, trunk, branch and flower. Bagworms were easily identified by the form of their cases. Each species had its own type of case, such as Chalioides kondonis with its cone-shape case. Level of parasitisation was low (0.00 – 18.54 percent). The rank of bagworm’s number and species found was as follows: home yards, public parks and flower seller. Controlling of the bagworms was done by mechanical hand picking. No chemical control was applied on these insect.
