Abstract: A method and apparatus for the non-toxic control of whitefly and other small bodied infestation insects on growing and cropping plants is provided. The apparatus comprises a vehicle element, the vehicle element being capable of being towed by a second vehicle through a field, at least one fan attached to the vehicle for pulling air and insects flying within the air from above the growing and cropping plants towards the vehicle, at least one heated grid element for heating the air that was pulled towards the vehicle by the fans, the heating element being attached to the vehicle, wherein the air is heated to a certain temperature such that substantially all of the insects flying above the growing and cropping plants are destroyed, but the cropping and growing plants are not destroyed. The method effectively eliminates all of the insect infestation in the treated areas without harming the growing and cropping plants.
