Insect Survey Bulletins
This web site is designed to bring you up-to-date news on the distribution and abundance of pest aphids at a regional scale. The information is based on data from a network of sixteen suction traps. The traps are emptied daily during the 'aphid season' and the aphids identified to species in most cases. Each trap is representative of what is flying over an area of radius approximately 80 km, but there is considerable local variation in aphid density at ground level. The data are used for fundamental studies on factors affecting the dynamics of aphid populations and to provide sponsors with information that aids aphid control decisions.
