The plasticity of sensory perception is provided partially by modulation of receptor cells. The electrical activity of American cockroach chemoreceptor cells in response to sex pheromone was measured under the influence of octopamine treatment and tracheal anoxia. Both experimental procedures caused decreased electroantennograms but affected spike activity(More)
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(More)
Tremendous adaptability of insects is predominantly provided by fast tuning of physiological functioning of an organism to the permanently changing environmental conditions. One of the mechanisms of plasticity in insects is modulation of performance of their sense organs by neurohormones. Activity of at least three out of four receptor cells located in(More)
In the visual systems of insects, different types of photoreceptors contribute to specialized visual channels that mediate distinct functions and behaviors. Large compound eyes of Periplaneta americana contain photoreceptors of two spectral classes, broadband green-sensitive photoreceptors and narrow-band UV-sensitive photoreceptors. Here, we investigated(More)
Interpopulation Variation in the Response of Male European Corn Borers Ostrinia nubilalis Hbn. (Lepidoptera: Crambidae) to Pheromone Blends: an EAG Study M. I. Zhukovskayaa*, O. G. Selitskayab, A. V.

Grooming, a common behavior in animals, serves the important function of removing foreign materials from body surfaces. When antennal grooming was prevented in the American cockroach, Periplaneta americana, field emission gun scanning electron microscopy images revealed that an unstructured substance accumulated on nongroomed antennae, covering sensillar(More)
The effect of serotonin solutions on the locomotor activity of cercariae with different swimming patterns, Cryptocotyle lingua and Himasthla elongate, was investigated during their lifespan using motion track analysis and a frame-by-frame count of behavioral elements. Serotonin caused a noticeable alteration of several locomotion parameters in both species(More)
Grooming is a well-recognized, multipurpose, behavior in arthropods and vertebrates. In this paper, we review the literature to highlight the physical function, neurophysiological mechanisms, and role that grooming plays in insect defense against pathogenic infection. The intricate relationships between the physical, neurological and immunological(More)
Insect antenna is a multisensory organ, each modality of which can be modulated by biogenic amines. Octopamine (OA) and its metabolic precursor tyramine (TA) affect activity of antennal olfactory receptor neurons. There is some evidence that dopamine (DA) modulates gustatory neurons. Serotonin can serve as a neurotransmitter in some afferent mechanosensory(More)
This study aimed to identify the main quantitative characteristics of antennal grooming in healthy American cockroaches. The experiments reported here provide the fi rst evidence that on average, cockroaches cleaned the right antenna significantly more frequently than the left, indicating that healthy insects have functional asymmetry in relation to(More)
