Behavioral responses to visual overstimulation in the cockroach Periplaneta americana L.

Cholesterol turnover in the American cockroach, Periplaneta americana (L.).

Modulation by octopamine of olfactory responses to nonpheromone odorants in the cockroach, Periplaneta americana L.

Olfactory receptor cells in insects are modulated by neurohormones. Recordings from cockroach olfactory sensilla showed that a subset of sensory neurons increase their responses to selected nonpheromone odorants after octopamine application. With octopamine application, recordings demonstrated increased firing rates by the short but not the long alcohol-sensitive sensilla to the nonpheromone vo...

The Odorous Attractant of the American Cockroach, Periplaneta Americana (l.)

1. Procedures have been developed for studying quantitatively the response of the male American cockroach to the odorous attractant of the female. 2. The percentage of male roaches responding to extracts of the attractant of the female has been found to vary with the log of the concentration of the attractant throughout a wide range. 3. Adaptation to the olfactory stimulus has been demonstrated...

New Analogs of Sex Pheromones of American Cockroach (periplaneta Americana L.): Behavioral and Electroantennographic Study

New chemical analogs as well as 2 main components, PA and PB, of the sex pheromone of Periplaneta americana L. have been studied by our original behavioral technique and electroantennogram recording. Behavioral assays included measurements of dose–response relationship and testing the effect of the analogs on peri-planones perception. Among 9 analogs, 7 elicited typical sex behavior of males. A...

odor-tracking performance in the American cockroach Periplaneta americana

Determining the location of a particular stimulus is often crucial to an animal’s survival. One way to determine the local distribution of an odor is to make simultaneous comparisons acrossmultiple sensors. If the sensors detect differences in the distribution of an odor in space, the animal can then steer toward the source. American cockroaches, Periplaneta americana, have 4 cm long antennae a...
