Delineating the calling pattern of from native and non-native plant species.

The study attempted to understand the effect of the host plants on the call parameters of native tree cricket, (Order: Orthoptera, Sub-order: Ensifera, Family: Gryllidae) while calling from native () and non-native host plant species ( and ). The study was conducted at four locations across India. Calls of were recorded on these host plants in the field and spectral and temporal parameters of calls were analysed. The results suggested that the peak frequency varied among the two non-native plant species while the difference in temporal pattern between the native and non-native host plants was observed only in the syllable period. The study also quantified the choice of calling positions of insects from the three-host species. The native chose non-native leaves extensively as a preferable site to baffle (37%). Differences in the call parameters and choice of the host plant by insects may ultimately affect the preference and performance of insects on invasive plants. The study would aid in exploring the underlying evolutionary and ecological processes of adaptive success of insects on non-native plants.
