THE IMPORTANCE OF PALPATION IN FOOD SELECTION BY A POLYPHAGOUS GRASSHOPPER (ORTHOPTERA, ACRIDIDAE) Academic Article

abstract

• The behavioral responses of final-instar nymphs of Schistocerca americana to a variety of acceptable and unacceptable plants were recorded. Palpation occurred on all plants and the palps are involved in both acceptance and rejection. On most unacceptable plants, rejection was at first dependent on biting the leaf, but subsequently on Lantana, Machaeranthera, Moms, and Physalis, rejection often occurred after palpation of the surface alone. This is consistent with the suggestion that associative learning occurs. This response did not wane even when the insects had been without food for over 2 h. There was also some evidence of an innate response to the surface characteristics of Physalis. The features of the surfaces that produced these responses were not determined. 1993 Plenum Publishing Corporation.
