Table 1.
Studies testing for sequential radiation in natural enemies, or natural enemy HAD in a single herbivore species which differentially associates with two host-plant species. To be included in this table, quantification of genetic difference between natural enemy populations was required. The genetic signature of HAD typically corresponds to FST ≥ 0.15 between sympatric, host-associated populations.
