Abstract
A device for killing insects, comprising a frame mounted for movement over the ground in a direction of travel, a first grid and a second grid mounted on the frame, the first grid and the second grid each extending laterally in relation to the direction of travel and being spaced apart in the direction of travel by a gap such that insects to be killed bridge the gap when the frame is moved over a field containing insects and a power supply connected to supply an insect killing voltage to one of the first grid and the second grid.

A device for killing insects, comprising:
- a frame mounted for movement over the ground in a direction of travel;
- a first grid and a second grid mounted on the frame;
- the first grid and the second grid each extending laterally in relation to the direction of travel and being spaced apart in the direction of travel by a gap such that insects to be killed bridge the gap when the frame is moved over a field containing insects;
- and
- a power supply connected to supply an insect killing voltage differential between the first grid and the second grid.
A device for killing insects, comprising:
- a frame mounted for movement over the ground in a direction of travel, the frame having a base;
- a live grid, a forward grounded grid and a rearward grounded grid, each mounted on the frame;
- the live grid, the forward grounded grid and the rearward grounded grid each extending laterally in relation to the direction of travel;
- the live grid being between the rearward grounded grid and the forward grounded grid and being spaced apart in the direction of travel from each of the rearward grounded grid and the forward grounded grid by respective gaps such that insects to be killed bridge the gaps when the frame is moved over a field containing insects;
- a barrier forming a base for the frame and the barrier extending forward of the grounded grid in the direction of travel for protecting against contact of the live grid and the grounded grid with vegetation;
- and
- a power supply connected to supply an insect killing voltage differential between the live grid and the forward and rearward grids.
A device for killing insects, comprising
- an open circuit electrical grid assembly having three parallel grid elements extending laterally and spaced from each other by insulating spacer posts;
- the grid elements being arranged to have a center grid element and a pair of outer grid elements;
- a means for supplying an insect killing voltage differential to the open circuit electrical grid assembly;
- and
- a lower plate extending laterally over the full width of the open circuit electrical grid assembly and the plate being positioned to allow a leading edge of the lower plate to contact and yield plants to agitate the plants to disturb insects and extending sufficiently forwardly and rearwardly of the grid elements to protect the plants from contacting the grid assembly as it passes over the plants.
