Using chemical pesticide intensively has raised serious problem of insect resistance. The goal of this study is to control mosquito populations by establishing mosquito control strategies with benefits of eco-friendly, sustainable, simple, highly specificity, without chemical pesticide, low cost and low human labor. Therefore, we evaluated the Taiwanese freshwater cyclopid copepods that may fit to traditional ovitrap and can be used as an integrated biological vector control strategy. Scheduled process to study and evaluate this strategy will contain three years. In the first year, field surveillance of freshwater cyclopid copepods will be carried out in Tainan, Kaohsiung and Pingtung in southern Taiwan, where are dengue hot spots with indigenous dengue or with highly mosquito index. Specific species with the ability and higher efficiency to prey mosquito larvae will be selected and then artificial-cultured in laboratory for the further study in the next year. Molecular diagnosis of unknown pathogenic microbes vectored by copepods and their sensitivity to cutrrent used pestiside will be further analyzed. In the second year, scheduled field evaluation experiments will be carried out based on the geographic information system (GIS) and clustering cases of indigenous dengue fever. This study will set up sentinel spots, such as biger artificial containers and flooding-basement, for long-term ecological surveillance. In the last year, evaluation and application of these biological agents incorporated to the ovitrap will be carried out to optimize the biological functions on mosquito surveillance and vector control. Over all, this study contains basic research of mosquito biology and microbiology, experimental design, and field applications. These kinds of ecological friendly approached bio-control strategies will lead to environmental sustainable. Goals achievement in this study revealed not only successes in vector control but also biological diversity.橈足類劍水蚤誘卵器登革熱病媒蚊誘卵滅幼器體腔真菌生態友善CyclopidCopepodsovitrapDengue fevervectorovi-larvicidal trapCoelomomycesEco-friendlyIntegrated Applications of Taiwanese Freshwater Cyclopid Copepods and Coelomomyces to Control Dengue Vectors
