Abstract


The objective research is to know the daily activities and preference of predatory birds Lanius sp. to several stages of Sexava spp. Ten predatory birds 12 to 14 months of age were bought at merchant bird in Yogyakarta. The study was conducted naturally under controlled condition in cages. Before the study was conducted the predatory birds were acclimatized for three days by feeding them cricket and gradually changed to Sexava spp. The young nymphs, old nymphs, adult male, and adult female of Sexava spp. were found at coconut plantation in Dumagin village became the new dietary of the predator. The result showed that Lanius sp. is a diurnal bird; the activities were dominated by hunting and preying (16.52%), followed by flying (6.53%), jumping (5.70%), and walking (4.58%). The Lanius sp. preferred to prey on significantly more nymphs of Sexava spp. than the adult. The birds prey proportionally on the young nymphs, old nymphs, male, and adult females for 50%, 41%, 5%, and 4%, respectively.

 

Penelitian bertujuan untuk mengetahui aktivitas harian burung predator Lanius sp. dan preferensinya terhadap berbagai fase hama Sexava spp. Burung berumur 1–1,2 tahun sebanyak 10 ekor diperoleh dari pedagang burung di Yogyakarta. Kajian preferensi burung predator Lanius sp. terhadap belalang Sexava spp. dilakukan di bawah kondisi fisik alami dan terkontrol dalam kandang uji. Sebelum kajian dilakukan burung predator diaklimatisasi selama 3 hari dengan pakan jangkrik dan berangsur-angsur diganti dengan belalang Sexava spp. Belalang Sexava spp. stadia nimfa muda, nimfa tua, imago jantan, dan imago betina diperoleh dari kebun kelapa desa Dumagin, dipakai sebagai mangsa burung predator. Hasil kajian menunjukkan bahwa Lanius sp. termasuk burung diurnal; aktivitas siang hari didominasi berburu mangsa dan makan (16,52%), diikuti terbang (6,53%), melompat (5,70%), dan berjalan (4,58%). Lanius sp. Secara signifikan lebih memilih stadia nimfa dibandingkan imago belalang Sexava spp. Proporsi nimfa muda, nimfa tua, imago jantan, dan imago betina yang dimangsa berturut-turut yaitu 50%, 41%, 5%, dan 4%.
