“…How the two species recognize their sex pheromone blends and achieve behavioral isolation is an issue that has been intensively investigated (Wang et al, 2005; Wu et al, 2013; Xu et al, 2016). The two species could be successfully hybridized in the laboratory (Wang and Dong, 2001; Wang et al, 2004; Zhao et al, 2006) and the fertile hybrids provide us with an unique opportunity to study the genetic basis of sex pheromone detection. In this study, we used SSR, calcium imaging, immunocytochemistry and digital 3D-reconstruction to comparatively study the pheromone detection in the two sister species, their hybrids and backcrosses.…”

“…C type sensilla in H. armigera display additional responses to (Z)-11-hexadecenyl acetate (Z11-16:Ac) and (Z)-11-hexadecenol (Z11-16:OH) (Chang et al, 2016; Xu et al, 2016), while those in H. assulta are reported to be activated also by (Z)-9-hexadecenol (Z9-16:OH) and Z11-16:OH, plus (Z)-9-hexadecenyl acetate (Z9-16:Ac) (Berg and Mustaparta, 1995) and Z11-16:Ac (Xu et al, 2016). These differences and the availability of hybrids of the two species provides an ideal system to study the genetic basis of their sex pheromone communication (Wang and Dong, 2001; Wang et al, 2004; Tang et al, 2005, 2006). …”

Hybridization of sympatric closely related species may sometimes lead to introgression and speciation. The sister species Helicoverpa armigera and Helicoverpa assulta both use (Z)-11-hexadecenal and (Z)-9-hexadecenal as sex pheromone components but in reversed ratios. Female H. armigera and male H. assulta could hybridize and produce fertile male hybrids, which can then backcross with females of the two parent species to get backcross lines in the laboratory. In this study, we compared the olfactory responses to pheromone compounds in the periphery and in the antennal lobes (ALs) of males of the two species, as well as of their hybrids and backcrosses. Single-sensillum recordings were carried out to explore characteristics of male-specific sensilla on the antennae, and in vivo calcium imaging combined with digital 3D-reconstruction was used to describe what happens in the macroglomerular complex (MGC) of the AL. The results show that the population ratio of the two male-specific types of olfactory sensory neurons responding to two sex pheromone components are controlled by a major gene, and that the allele of H. armigera is dominant. Consistently, the study of the representative areas activated by sex pheromone components in the ALs further support the dominance of H. armigera. However, the topological structure of the MGC in the hybrid was similar but not identical to that in H. armigera. All subtypes of male-specific sensilla identified in the two species were found in the male hybrids and backcrosses. Moreover, two new subtypes with broader response spectra (the expanded A subtype and the expanded C subtype) emerged in the hybrids. Based on the inheritance pattern of the pheromone sensory system, we predict that when hybridization of female H. armigera and male H. assulta occurs in the field, male hybrids would readily backcross with female H. armigera, and introgression might occur from H. assulta into H. armigera through repeated backcrossing.

“…Wang & Dong (2001) reported that the reciprocal F 1 generations and backcrossed generations from the two sibling species could be obtained successfully in laboratory conditions, allowing genetic studies of different characters. Wang et al. (2004) reported that there was a clear contrast in feeding preference between the two species, H. armigera having a strong feeding preference for cotton and H. assulta preferring to feed on pepper rather than on cotton.…”

The genetic basis of larval host-plant preference was investigated in reciprocal F 1 , F 2 , and backcrossed generations derived from hybrid crosses between the generalist species Helicoverpa armigera (Hübner) and the closely related specialist species Helicoverpa assulta (Guenée) (Lepidoptera: Noctuidae). Host-plant preference for cotton [ Gossypium arboreum L. (Malvaceae)] and pepper [ Capsicum frutescens L. (Solanaceae)] of fifth-instar caterpillars was tested by using a two-choice leaf-disk assay. Helicoverpa armigera and H. assulta were significantly different in their feeding preferences, but the difference was not significant in the reciprocal hybrids, which showed there were no maternal/cytoplasmic effects. Comparisons of feeding preference between different groups of females or males demonstrated that the trait was not controlled by sex-linked loci. The distributions of feeding preference index values for crosses that carried similar complements of autosomal genes were not significantly different, whereas crosses with different complements of autosomal genes were associated with significantly different feeding preferences, indicating that feeding preference of the two species for cotton and pepper, respectively, is controlled by autosomal genes. It was found that one major autosomal locus affected this feeding preference, with the H . armigera -derived alleles being partially dominant to those carried by H. assulta . The genetic analysis of hybrids contributes to understand the evolution of feeding preference in these closely related species.

1. Genetic analysis of feeding preference can make an important contribution to our understanding of the evolution of host-plant selection in phytophagous insects. Two closely related flea beetles, Altica viridicyanea (Baly) and Altica fragariae Nakane, with separate host plants [ Geranium wilfordii Maxim. and Duchesnea indica (Andrews) Focke respectively] were hybridised to analyse the inheritance mode of feeding preference.2. Adult hybrid F 1 ( A. viridicyanea female × A. fragariae male) preferred G. wilfordii to D. indica in two-choice tests, regardless of which plant they had fed on as larvae. Adults of one backcross to A. fragariae preferred D. indica to G. wilfordii , and the two backcrosses to A. viridicyanea consumed only a very small percentage of D. indica . Adult females of F 2 showed no significant preference, whereas males of F 2 showed slight preference for G. wilfordii over D. indica .3. Both the mean feeding preference and the segregation pattern of beetles indicate that the feeding preference of A. viridicyanea and A. fragariae for G. wilfordii and D. indica , respectively, is mainly controlled by a major dominant autosomal gene (or several genes). 4. The variance between feeding preference and oviposition preference of female F 2 indicate that the two behaviour traits of Altica species are controlled by different gene(s).
