Target only Harmful Insects on the Field

Science Innovations

University of Copenhagen researchers have developed an algorithm when used in tandem with a sensor, can identify fields with large number of harmful instects. This helps the farmer target them with pesticides . Scientists are trying to make the sensors mobile so that they can measure exactly where harmful insects are in a field. This can minimise the use of pesticides in the field and reduce unnecessary harm to beneficial insects such as wasps, bees, ladybugs, phytoselid mites and wolf spiders. The solar powered sensors detects the speed of insect wingbeats, body size in relation to wingspans and colour. It is passed along an algorithm that categorizes the insects into species groups and alerts the farmer via a computer or mobile device.
