Ovitrap and method of controlling vector born disease

An ovitrap comprising:

• a container, a cover, and a dividing mechanism for dividing the container into two regions, which in use are filled with water, and which communicate via an opening such that a first volume below the dividing mechanism defines a larvae trapping region, and a second volume above the dividing mechanism defines an egg receiving region, a light source having a cool, white spectra, with two peaks, a first peak at 450 nm-470 nm, and a second peak at 500 nm-700 nm, the light source mounted above the container and positioned to direct light downwards at a water surface, such that when the light source is turned on to create a photo stimulus, larvae respond by moving in a direction away from the light source, from the second volume into the first volume below the dividing mechanism via the opening, and a gating mechanism operatively linked to the light source which opens and closes the opening when the light source is respectively turned on and off, such that the larvae are trapped in the first volume.
