Detecting pest insects across large areas means placing vast numbers of traps, with associated costs to set them up and check them regularly. Grid patterns have been the traditional choice, but a new study shows trap-placement patterns using parallel lines could be just as effective with much lower servicing requirements.
Unmanned aerial vehicles are finding a variety of applications in agriculture, and a team at the University of Idaho has developed an open-source drone design that can successfully sample insects in a field.
A group of researchers gets creative with some simple materials: strips of cardboard, rolled up and tied with string. Affixed to tree trunks or limbs, the "trunk refugia" show promise as a simple and inexpensive tool for sampling tree-dwelling insects and arthropods.
In a new study at the University of Arizona, researchers used body-mounted cameras to evaluate the efficiency of two insect pest sampling techniques—a sweepnet and a vacuum—in a cotton field. The perspective offered new insights into how such methods can be evaluated and could help growers and integrated pest management professionals further fine-tune their sampling techniques.
