Feasibility of using domestic, high-definition video cameras to monitor insect predation.
Abstract
Domestic, high definition video cameras are capable of recording predatory events in cotton crops in considerable detail. Modifications to the power supply and shielding to protect the cameras from the elements can be made easily and cheaply.The cost per camera and associated hardware is approximately AUS$2,200. Software to support a set of cameras would cost another $1000 dollars although this would depend on the quality of the images needed, the size of the files to be stored and the time available to download events. We assume portable computers and various large capacity hard drives are available. Both are relatively cheap these days.The cameras are likely to get too hot if used in full sun positions (even with a sun shield) during the hottest parts of the day for some regions (ca. 12-00 to 15:00 pm in mid-summer), however for many months and over periods when insects are most active (dawn and dusk) temperatures would be acceptable. The camera houses used in this project would be sufficient for many studies.This project has captured parasitism of a late instar Helicoverpa larvae by a large Ichneumonid wasp. This was captured by leaving the cameras for 3 hours unattended from 6-00 am to 9-00 am in a clover pasture at UNE. This event is an excellent example of the performance of the camera system tested in this project.
