Abstract

Keanekaragaman kupu-kupu dari Gunung Salak, Indonesia. Penelitian mengenai kupu-kupu telah banyak dilakukan di seluruh dunia, namun informasi basis data tentang kupu-kupu sangat terbatas di Indonesia. Penelitian ini bertujuan mengetahui spesies dari komunitas kupu-kupu yang berada di hutan alam dan habitat sekitarnya di areal Gunung Salak, Taman Nasional Gunung Halimun-Salak, Bogor, Jawa Barat. Pengumpulan data ekologi dilakukan pada bulan September sampai dengan Desember 2003. Survei kupu-kupu dilakukan dengan menggunakan transek sepanjang 200 meter di lima lokasi terpilih yang berbeda. Survei mengumpulkan 237 individu dari 28 spesies yang terdiri dari dari 4 famili. Famili yang paling sering dijumpai adalah Nymphalidae. Pencatatan yang dilakukan menunjukkan bahwa Nymphalidae memiliki jumlah species terbanyak dan kelimpahan individu tertinggi. Dalam tataran species, Melanitis leda adalah spesies dengan kelimpahan tertinggi. Penelitian lebih jauh diperlukan untuk menyediakan informasi yang lebih lengkap tentang komunitas kupu-kupu di daerah ini.

Abstract

The effectiveness of Neochetina eichhorniae as a biocontrol agent of waterhyacinth was evaluated in West Java and DKI Jakarta. The objective of this research was to study the implication of the existence of N. eichhorniae on waterhyacinth. Research was conducted in several freshwater ecosystem infested by waterhyacinth and N. eichhorniae, including Cibinong and Lido lakes (Bogor District), Muara Angke Sanctuary (North Jakarta), and Citarum Hulu river (Purwakarta District), conducted during April to August 2004. The impact of N. eichhorniae on waterhyacinth was evaluated by leaf damage intensity and growth parameter of the plant. Results showed that there was no correlation between waterhyacinth and the occurrence of the N. eichhorniae. The population of N. eichhorniae adults was significantly low in any locations studied. Thus, the existence of the biocontrol agent can not result in decreasing of waterhyacinth population.

Abstract

The establishment of Neochetina spp. as biocontrol agent of waterhyacinth are related to the weevil’s ability to disperse and to increase their population sizes. The objective of this research was to study the distribution and abundance of Neochetina spp. at several areas in West Java and DKI Jakarta. The field research was done in several freshwater ecosystem infested by waterhyacinth, including Cibinong and Lido lakes in Bogor, irigation canal in Karawang, Muara Angke Sanctuary in North Jakarta, and Citarum Hulu river in Purwakarta, during April to August 2004. Coordinate and elevation of the research sites where N. eichhorniae and N. bruchi found were reported, while their abundances were observed by direct hand-collection technique. The results of the research showed that N. eichhorniae was widely distributed and established in most sampling sites, except in Karawang, whereas N. bruchi was not found in any sampling sites. Our observations also indicated that N. eichhorniae was distributed passively so that the weevil couldn’t colonize isolated habitats or locations.
