## Abstract

An acoustic lethal ovitrap, comprising a tray defining an inner space and having a floor which slopes downwardly toward a center point, and also having a side wall defining a curved internal radius; a housing mounted within the tray; a transducer and power/control unit mounted within the housing for generating acoustic energy at a desired wavelength; a solar panel mounted on the housing and producing power for the transducer and power/control unit of the apparatus; wherein the tray captures water and attracts mosquitos to the water within the tray, and the transducer within the housing generates acoustic energy sufficient to kill mosquitos as they are attracted to the device.

## Claims

### Claim 1

An acoustic lethal ovitrap, comprising:
a tray defining an inner space and having a floor which slopes downwardly toward a center point, and also having a side wall defining a curved internal radius;
a housing mounted within the tray;
a transducer and power/control unit mounted within the housing for generating acoustic energy at a desired wavelength;
a solar panel mounted on the housing and producing power for the transducer and power/control unit of the apparatus;
wherein the tray captures water and attracts mosquitos to the water within the tray, and the transducer within the housing generates acoustic energy sufficient to kill mosquitos as they are attracted to the device.

### Claim 2 (depends on 1)

The apparatus of claim 1 wherein the transducer generates acoustic energy resonant with dorsal tracheal trunk of a mosquito causing it to rupture, and cavitation which causes shock trauma to an entire body of the mosquito.

### Claim 3 (depends on 1)

The appatus of claim 1, wherein the transducer is an acoustic transducer having a cylindrical piezo ceramic for generating sound in a horizontal toroid.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the tray defines an open top area to expose water to sight of female mosquitos.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the tray has drain ports to allow vertical oviposition sites for mosquitos.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the tray has two-textured black interior, smooth below the drain ports and slightly rough above the drain ports.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein the floor sloping downwardly toward the center keeps the center filled with water, ensuring contact with water at all times such that the device does not become a mosquito breeding site.

### Claim 8 (depends on 1)

The apparatus of claim 1, further comprising a center cradle to offset the transducer from the trap base.

### Claim 9 (depends on 1)

The apparatus of claim 1, wherein the transducers and power/control unit have a ceramic ring that generates the sound and is a water level sensor.
