Age structure of Anopheles subpictus (Diptera:Culicidae) collected by a light trap in Halmahela, Indonesia.
Age structure of Anopheles subpictus Grassi was studied at a Halmahela village, Indonesia. Ovary development of females reared with 2% sugar solution after emergence ceased at Stage I and their ovary size remained small (mean length x width = 0.68 x 0.18 mm). Females with such small ovaries occupied 21.2% of unfed Stage I females in cattle-bait samples. The remaining unfed Stage I or II females had cleary larger ovaries (mean 1.17 x 0.39 mm). Unfed Stage I or II females collected by the outdoor light trap all had large ovaries (mean 1.42 x 0.34 mm) irrespective of stages and parity. The parous rate of unfed stage I or II females collected by the light trap (86.6%) was significantly higher than that of cattle-bait samples (69.6%). Feasibility of using outdoor light trapping in malaria entomology was discussed.
