This research was aimed to study the population dynamics of egg parasitoids of H. armigera on unsprayed fields of cotton monoculture and intercropped with maize. The plot size of each field was 19 m x 20 m, with five replicates. We collected H. armigera eggs from both fields periodically since 23 days after planting (dap) to 100 dap. The eggs were collected on 9 sample units (size of sample unit: 1 m2) in 7-days interval. The number of collected and parasitized eggs was recorded and the emerged parasitoids were identified to species level. The result showed that the fluctuation pattern of H. armigera egg population was not different on cotton monoculture and cotton intercropped with maize. The parasitoid population was relatively high during the flowering phase of cotton and maize. The parasitoids of H. armigera eggs found in cotton monoculture and cotton intercropped with maize were T’toidea armigera, T’toidea guamensis, T’toidea bactrae bactrae, T’toidea bactrae fumata, T. chilonis and T. chilotraeae . The dominant species on early season until the flowering phase of the plants was T’toidea armigera, while on the latter phase of the plant phenology was T. chilotraeae. Implication of this population dynamics and the succession of the parasitoids in biological control are discussed. %U https://jurnal.unej.ac.id/index.php/JPH/article/view/27 %J Jurnal Pengendalian Hayati %0 Journal Article %P 78-82%V 1 %N 2 %@ 2721-7701 %8 2012-12-05
