Monitoring airborne movement of crop insect pests and beneficials

Abstract

This chapter explores monitoring airborne movement of crop insect pests and beneficials. The chapter begins by highlighting the importance of trapping methods when it comes to monitoring specimens. This is then followed by a review of the visual observation of insects and a discussion of various forms of radar that can be used, such as scanning entomological radars, vertical-looking and weather surveillance radars. A section on optoelectronics is also provided, focusing specifically on short-range and long-range monitoring as well as imagers and the strengths, limitations and prospects of these devices. The chapter also provides a review of radiotelemetry and harmonic radar as well as a case study on moths over a cotton crop.
