Hypersensitivity to chironomid larvae.

Chironomid larvae (red midge larvae) are often used by aquarists as fish food. Their hemoglobins can cause IgE-mediated allergic diseases in exposed and unexposed people. The aim of this study was to find out the prevalence of positive skin tests to chironomids in patients suffering from rhinitis and/or bronchial asthma in Ciudad Real (Spain).
