  1. The number of observations and proportion of potential mosquito larval habitats containing pupae are presented by habitat type and size for control and intervention sites with statistical comparison using logistic regression (significant values appear in italics). A small number of habitats that were not classified into larger groups or the size was not able to be determined were not included in the above statistical comparison
