Abstract

Event Abstract Back to Event Changes in the selectivity of phonotaxis and its neuronal correlates in response to prothoracic nanoinjection of modulators in female cricket Acheta domesticus Benjamin Navia1*, Ashley Groeneweg2, John Stout2 and Gordon Atkins2 1 Kettering College, Department of Science and Math, United States 2 Andrews University, Department of Biology, United States Phonotaxis in female crickets has been shown to exhibit variability. While some females respond to syllable periods typical of the males’ calling song (50–70 ms), others only respond to calling songs with shorter or longer syllable periods, outside the range of males’ calling songs. Other females are not selective to any syllable period and respond to the full range of calling songs. Nanoinjection of histamine into the prothoracic ganglion decreases phonotactic selectivity. Nanoinjection of antihistamine has the reverse effect. Nanoinjection of Juvenile Hormone III increases phonotactic selectivity, while a protein kinase C inhibitor blocks the effect of Juvenile Hormone III. This suggests that Juvenile Hormone II exerts its effects through a protein kinase C pathway. The L3 neuron is a prothoracic interneuron in female crickets that responds selectively to the syllable period of the male’s calling song. The L3 neuron has been proposed to be responsible for syllable period-selective responses during phonotaxis. If this is true, then L3s should show variable responses, which would parallel the phonotactic behavior. Preliminary results indicate that the application of histamine to the prothoracic ganglion decreases the selective responses, whereas injections of antihistamine increases L3s’ selectivity. This mirrors the effect of these two modulators on phonotactic selectivity. Juvenile Hormone applications also increase the selective responses of L3 similar to its effect on phonotaxis. The effect of protein kinase C blockers on the response of L3s is currently being tested. To date the data support the hypothesis that processing by L3 contributes to the syllable period selective phonotaxis observed in this species. References Atkins G., Kilmer J. et al.
