Behavioural differences in host-finding among different maize germplasms have not been studied, and may contribute to the pest status of stunting pathogens vectors. In this study, we compared the preferences of a specialist leafhopper, D. maidis (Hemiptera: Cicadellidae), and a more generalist planthopper, P. maidis (Delphacidae), on a suite of three maize cultivars, a temperate and a tropical germoplasm and a landrace. Moreover, we analysed the volatile organic compounds (VOCs) emitted constitutively by the maize plants that could act as non- contact cues determining host-finding.
