title: Studies on the ovitraps baited with hay and leaf infusions for the surveillance of dengue vector, Aedes albopictus in northeastern India.
abstract: Ovitraps baited with hay and leaf infusions were evaluated for enhancing the   oviposition response of gravid females of the dengue vector Aedes albopictus. The egg   density per trap (mean ± SEmean) was the highest with 30% infusions of Pennisetum grass hay   (623.6 ± 41) and rice straw (580 ± 51.3), which corresponded to oviposition activity index   (OAI) of 0.62. Infusions (5-50%) of mango and banana leaves with OAI ranging from -0.36 to   0.39 were not observed to enhance the oviposition response significantly over control. Rice   straw and Pennisetum grass hay are available round the year in northeastern India and the   use of these infusions can be a cost effective way to augment the ovitrap surveillance of   dengue vectors.
