A new study shows how stress to soybean crops caused by the soybean aphid can be detected remotely by drone-based multispectral imagery.
In a recent study in Germany, targeted delivery of insecticides by unmanned aerial vehicles was effective against oak processionary moths. Researchers say such drones are suitable for aerial spraying during field studies and may open new doors for "precision forestry."
Researchers at Purdue University are developing new ways to apply spectroscopy in service of greater food security. By analyzing light reflected by plants, they can detect compounds the plants produce soon after they face an insect pest attack or other stressor.
When a colony of honey bees grows to about 4,000 members, it triggers an important first stage in its reproductive cycle — the building of a special type of comb […]
