740 Transmission of human disease-causing microorganisms is not, however, entirely the domain of parasitic insects. Many insects, especially flies, may act as mechanical vectors, contaminating human food as they rest or defecate on it, with pathogens picked up during contact with feces or other organic waste. Examples of such insects and the diseases transmitted by them are listed in Table 24.1.

A third category of insects that directly affect humans includes those that may bite or sting when accidental contact is made with them, for example, bees, wasps, ants, some caterpillars (with poisonous hairs on their dorsal surface), and blister beetles. Normally, the effect of the bite or sting is temporary and nothing more than skin irritation, swelling, or blister formation. Bee stings, however, may cause anaphylaxis or death in some sensitive individuals.
