The Role Of Octopamine In Syllable-Period Selective Phonotaxis In Female Cricket Acheta Domesticus, Darley Magno
The Role Of Octopamine In Syllable-Period Selective Phonotaxis In Female Cricket Acheta Domesticus, Darley Magno
Honors Theses
Female crickets respond phonotactically to the calls of conspecific males. Females' phonotaxis has been reported to be variable, ranging from unselective to selectve in response to calls with varying syllable periods (30-90 ms). Octopamine, an intertebrate neurotransmitter, has been reported to increase aggressive behavior in crickets, (Stevanson et al. 2005) but the effects of octopamine on behaviors such as phonotaxis have not been investigated. The goal of this study is to determine the effects of octopamine on the syllable-period selective phonotactic response of females. Results suggest a decrease in phonotactic responsiveness shown by 5-10 day-okds after prothroacic nanoinjection of octopamine.
Chelerythrine Chloride And Its Effects On Phonotactic Behavior In Female Crickets Acheta Domesticus, Haneul Shin
Chelerythrine Chloride And Its Effects On Phonotactic Behavior In Female Crickets Acheta Domesticus, Haneul Shin
Honors Theses
Selective phonotaxis by female crickets has been shown to be variable. Mechanisms which underlie such behavioral variability are being studied. Juvenile Hormone III is a neuromodulator that has been shown to increase selectivity in phonotactic behavior of female crickets. In an attempt to further explore its effects on the behavioral responses of femaile crickets, experiments have been performed with chelerythrine cloride that is known to have an opposite effect of Juvenile Hormone III. Chelerythrine chloride, a potent protein kinase C blocker, has been hypothesized to block the effect of Juvenile Hormone III which acts through a protein kinase C pathway, …
