Coupling of EAD to GC was first achieved in 1969, and further developed in 1975 in studies on the sex pheromone of the European grape vine moth. The use of capillary columns allowed a continuous stream of the GC effluent on to the antenna, which had previously not been possible. The GC effluent can be split between the EAD and an EID allowing the correlation of biological response to identified compounds (Figure 12). Recent studies on the Egyptian armyworm found that the use of the whole insect provides better results than the use of the excised head, or the antenna, and showed that as little as 15 pg of compound could be detected. 

With the exception of the corn earworm, fall armyworm, pink bollworm, and Egyptian cotton leafworm programs, these disruption tests were preliminary studies carried out on small plots without optimization of disruptant formulations and with little assessment of crop damage.
