Abstract

Weaver ants (Oecophylla smaragdina (Fabricus)) are carnivorous insects and play a role as biocontrol agents in urban habitats. This study aims to analyze the foraging behavior of O. smaragdina in two different habitats, namely urban and non-urban. The two locations are characterized by differences in the intensity of human interaction and the distance between the trees and the tree canopy. The behavioral observation method uses all sampling events with five behavioral categories: lurking (M1), approaching (M2), carrying (M3), communicating between ants in a colony (K1), and competition with other ants (K2). We tested three different types of feed: chick scraps, Tenebrio molitor Linnaeus larvae, and sugar. The results showed that there were three sequences of foraging behavior in urban areas, namely: (1) M1, M2, K1, M3, (2) M1, M2, K1, M3, K2, and (3) M1, M2, K2, M3. Meanwhile, there is only one pattern in non-urban areas, namely M1, M2, M3. Approaching food (M2) and lurking food (M1) were the dominant responses of O. smaragdina in urban and non-urban areas. In urban areas, broiler chickens were the type of feed most approached by ants, followed by sugar and beetle larvae. O. smaragdina in non-urban areas also preferred chicken pieces as feed compared to the others, but only one individual O. smaragdina approached (M2) chicken pieces and none approached the others. Foraging ants are more active at high temperature and low humidity, compared to low temperature and high humidity. Therefore, the foraging behavior of O. smaragdina is influenced by habitat factors.

Abstract

Keberadaan burung Cenderawasih semakin terancam punah karena perburuan liar, dan rusaknya habitat, oleh orang-orang yang tidak bertanggung jawab. Penelitian ini bertujuan untuk mengetahui jenis-jenis burung Cenderawasih yang ada di Hutan Kampung Nunsyari Distrik Yapen Timur Kabupaten Kepulauan Yapen Provinsi Papua, mengetahui bentuk penyebaran jenis-jenis cenderawasih di Hutan Kampung Nunsyari Distrik Yapen Timur Kabupaten Kepulauan Yapen, dan mengetahui gambaran umum habitat burung cenderawasih di Hutan Kampung Nunsyari Distrik Yapen Timur Kabupaten Kepulauan Yapen. Metode yang digunakan pada penelitian ini adalah metode Index Ponctuelle de Abondance (IPA). Teknik analisis data yang digunakan adalah Kelimpahan Burung, Keanekaragaman Jenis Burung, Frekuensi Atau Sebaran Burung. Hasil analisis kelimpahan menunjukkan P. m. jobiensis sebanyak 0.68, Manucodia jobiensis sebanyak 0.09, Cicinnurus regius 0.14, dan Diphyllodes magnificus 0.090, keragaman jenis burung Cenderawasih adalah sebesar 1, Frekuensi Relatif Sebaran Burung jenis Paradisaea minor jobiensis terdapat 68%, Manucodia jobiensis 9%, Cicinnurus regius 14%, dan Diphyllodes magnificus 9%.
