Abstract
AbstractThe effect of different habitat complexity structure on the feeding success of predatory
Dragonfly and Damselfly over the four of three hours trials was tested using an artificial
habitat complexity structure. Complexity of artificial habitat structure was performed using
woody bamboo stick of 5 cm in length and 2 mm in diameter. The artificial habitats were set
in plastic tank with length and wide of 17 cm and 11.5 cm, respectively and 5.5 cm high. The
deep of water colom was about 4.5 cm. Preys were larvae of mosquitoes. There was highly
significant of feeding success of predators in simple structure of habitats and significant
enough in complex structure of habitats. In other words, feeding success of predatory
Dragonfly and Damselfly was much higher in the simple habitats structure compared to that
of the complex one.

Abstrak
Pengaruh kompleksitas struktur habitat terhadap keberhasilan pemangsaan predator Dragonfly
dan Damselfly selama empat kali tiga jam perlakuan diteliti di laboratorium menggunakan
habitat buatan. Kompleksitas struktur habitat dibuat dengan tongkat dari bambu berukuran
panjang 5 cm dengan diameter 2 mm. Habitat buatan dibuat di bak plastik berukuran panjang
dan lebar masing-masing 17 cm dan 11,5 cm, dan tinggi 5,5 cm dengan kedalaman kolom air
sekitar 4,5 cm. Larva nyamuk digunakan sebagai pangsa dalam penelitian ini. Setiap
perlakuan terdiri dari dua ulangan. Setiap perlakuan berlangsung empat kali masing-masing
selama tiga jam. Hasil memperlihatkan, keberhasilan pemangsaan Dragonfly dan Damselfly
sangat signifikan pada habitat stuktur sederhana, dan cukup signifikan pada habitat yang
kompleks. Dengan kata lain, keberhasilan pemangsaan Dragonfly dan Damselfly jauh lebih
tinggi pada habitat berstruktur sederhana dibanding dengan pada habitat berstruktur
kompleks.
