Ichneumonidae of Taman Rimba Kenong

anglais. Species diversity and abundance of Ichneumonidae(Hymenoptera: Ichneumonoidea) in Taman Rimba Kenong was studied. A total of 72 ichneumonid wasp individuals comprising of 33 genera were collected. The cryptines had the highest number of 43 individuals belonging to 20 genera followed by the campoplegines (13 individuals and 5 genera), metopiines (8 individuals and 2 genera) and pimplines (5 individuals and 3 genera). Comparison of the ichneumonids abundance between the Kesong and Kelahup trails revealed a significant different results (p0.05). Potential factors that contributed to the differences were discussed. The genus Goryphlls was the largest group having 11 specimen, and this was followed by the Hypicera (6 individuals) and Venturia (5 individuals) all of which were members of cryptines. Two genera (Epelaspis and Laguna) were found to be new records for Taman Rimoa Kenong and Malaysia. The morphological characters of both genera were illustrated and described. The Shannon diversity Index (H`) indicated that the ichneumonids species in Kesong trail was not significantly higher (H`=2.942) than in Kelahup trail (H`= 2.X67l. Overall, however, the H` in Taman Rimba Kenong was 3.172. This value was considered high and comparable with other large scale forests (e.g. Hulu Muda Forest Reserve. Belum Forest Reserve and Danum Valley Conservation Area, Sabah). The results indicated that Taman Rimba Kenong is one of the rich areas for the purpose or species conservation especially for the Ichneumonids wasps.

inconnu. Kepelbagaian spesies dan kelimpahan lchneumonidae (Hymenoptera: Ichneumonoidea) di Taman Rimba Kenong telah dikaji. Sejumlah 72 individu penyengal ikneumonid yang tergolong dalam 33 genus telah dikutip. Cryptine mempunyai oilangan yang terbesar dengan 43 individu yang tergolong dalam 20 genus, diikuti oleh Campoplegine (13 individu dan 5 genus), Metopiine (8 individu dan 2 genus) dan Pimpline (5 individu dan 3 genus). Perbandingan kelimpahan ikneumonid antara rintis Kesong dan Kelahup menunjukkan hasil yang berbeza secara signifikan (p0.05). Faktor yang berkemungkinan menyumbang kepada perbezaan itu telah dibincangkan. Genus Goryphus ialah yang terbesar dengan 11 spesimen, dan ini diikuti oleh Hypicera (6 individu) dan Venturia (5 individu) semua adalah anggota Cryptine. Dua genus (Epe/wpis dan Laguna) adalah rekod barn bagi Taman Rimba Kenong dan Malaysia. Sifat morfologi kedua-dua genus telah diilustrasi dan dihuraikan. Indeks Kepelbagaian Shannon (H`) menunjukkan spesies ikneumonid di rintis Kesong adalah tinggi secara signifikan (H`=2.942) daripada rintis Kelahup (H`= 2.867). Secara keseluruhan, H` di Taman Rimba Kenong adalah 3.172. Nilai ini telah dianggap tinggi dan sebanding dengan hutan yang lebih besar (misalnya Hutan Simpan Hulu Muda, Hutan Simpan Belum dan Kawasan Pemuliharaan Lembah Danum, Sabah). Hasil telah menunjukkan Taman Rimba Kenong adalah salah satu kawasan yang kaya bagi tujuan pemuliharaan spesies khususnya penyengat Ikneumonid.
