Hybridization between Helicoverpa armigera and Helicoverpa assulta (Lepidoptera: Noctuidae): development and morphological characterization of F1 hybrids

Popis výsledku v původním jazyce

Hybridization between two species ? H. armigera and H. assulta were studied. The cross between female of H. armigera × male of H. assulta yields only fertile males and sterile individuals without any penis and valva or ostium bursae on the genital segments. Sterility was done by not only external sex organs, but also the varieties of the abnormal internal reproductive system: 1) without internal reproductive organs, 2) with 1 to 3 the undeveloped bursa copulatrix, or 3) with one or two undeveloped testes. The normal male hybrid adults show higher flight activity in comparison with males of both species. On the other hand, the cross between female of H. assulta × male of H. armigera yields morphologically normal offspring of males and females. We describe some morphological abnormalities found in hybrid pupae and adults, attributed to large sex-linked or cytoplasmic incompatibility, and analyze the ratios of female, male, and abnormal individuals in F1, F2 and backcross offspring.
