AbstractBACKGROUND: The invasion ofHelicoverpa armigera(Hübner) (Lepidoptera: Noctuidae) into the New World has made it possi-ble for this pest to hybridize with a native American species,H. zea(Boddie), under natural conditions. We investigated the via-bility and development of hybrids of these twoHelicoverpaspecies. We reared the parental species and evaluated crossesbetweenH. armigeramales andH. zeafemales andvice versa, two intercrosses between hybrids, and eight backcrosses betweenhybrids and parental species. We estimated the length of immature stages, fecundity, survival, sex ratio, and heterosis.RESULTS: Although hybridization occcurred, with heterosis during the development of immatures, reproductive incompatibil-ities also were observed between the parental species and between hybrids from subsequent crosses. The interspecific crossesbetween hybrids and backcrosses confirmed the possibility of introgression events and their perpetuation infield populations.The results indicate that hybridization events are favored at high population levels, while at low population levels the?speciesidentities?will be maintained.CONCLUSIONS: The possibility of interspecific geneflow and its perpetuation through successive crosses and backcrosses sug-gests several recommenations for management. Populations of both species should be maintained at an equilibrium level toreduce the chance of interspecific crosses, which are presumably more likely to occur during pest outbreaks. The existenceof hybridization and resistance to different active pesticide ingredients should be monitored. All practices related to managingthe resistance of these pests to chemical and biological insecticides should be systematized to reduce the chance of selectingfor resistant individuals.
