The adaptive nature of the foam proteome produced by Mahanarva spectabilis (Hemiptera: Cercopidae) when infesting forage grasses with different levels of antibiosis-type resistance.

ABSTRACT: The spittlebug Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) produces a stable extracellular foam during its nymphal stage, which plays a critical role in survival and host plant interactions. In this study, we present the first comprehensive proteomic characterization of foam secreted by M. spectabilis nymphs, using a shotgun LC-MS/MS approach. We analyzed the foam produced by nymphs feeding on four forage cultivars showing different levels of antibiosis-type resistance against M. spectabilis, as follows: Cenchrus purpureus cv. Pioneiro (moderately resistant) and cv. Roxo de Botucatu (susceptible); Urochloa brizantha cv. Marandu (resistant), and Urochloa decumbens cv. Basilisk (susceptible). A total of 196 proteins were identified, including a substantial fraction of unann
