Euclytia flava

(Townsend, 1891)

Euclytia flava is a tachinid fly of stink bugs (Pentatomidae) native to North America. The has been demonstrated to use and as for host-finding, with distinct kairomone strains that respond to different host species' . It has been tested for applications, showing preference for pentatomid species over hosts in choice tests. The species can be captured in large numbers using pheromone-baited traps targeting its native host Podisus maculiventris.

Kairomone Strain Variation

Multiple strains of E. flava coexist naturally, with different strains responding to of different . This cryptic variation has implications for understanding host-shift evolution and for selecting effective strains.

New Associations Hypothesis

The has been used to test the 'new associations' concept, showing that wild females preferred to oviposit on pentatomid species rather than known in both field and laboratory conditions.
