This invention provides the application of compounds in attracting or controlling midges, relating to the field of
midge control technology. Through screening and identification, this invention has obtained five compounds (
butyric acid,
butyraldehyde,
propionaldehyde, 2-hexanone, and
acetophenone) with significant attractant activity against Formosan
midge. These compounds can be used alone or in combination, are
environmentally friendly and have a high affinity for non-target organisms, greatly enriching the candidate resource of
midge attractants. They can be directly applied to the monitoring and large-scale
trapping of midges, effectively reducing midge
population density, thereby reducing midge bites and the spread of midge-borne diseases, which has significant
public health implications.
