Consummatory Behavior
Neotropical Entomology (39)1 2010
Abstract
We examined behavior of larvae of L4 L.longipalpis on a soil substrate when exposed to the fire ant Solenopsis invicata (Westwood). When ants were absent, most larvae tended to remain at or close to the soil surface, but when ants were present the larvae burrowed into the soil. Sandflies seek refuge...

Abstract
Actions of 5alpha-pregnan-3alpha-ol-20-one (3alpha,5alpha-THP), in the midbrain ventral tegmental area (VTA) modulate sexual receptivity of female rats. Actions of 3alpha,5alpha-THP at GABAergic substrates in the VTA are known to modulate consummatory aspects of sexual behavior among rodents, such a...

Abstract
A series of experiments studied the effects of the kappa-opioid receptor agonist U50,488H on consummatory successive negative contrast (cSNC) in rats. In cSNC, previous experience with a 32% sucrose solution leads to greater rejection of 4% sucrose than exclusive experience with 4% sucrose. Experime...

Abstract
Aplysia egg laying is a complex behavior requiring synchronized activity in many organs. Aspects of the behavior are synchronized via the direct effects of peptide bag cell neurohormones and via stimuli arising during the behavior. Stimuli synchronizing egg laying were examined by treating A. fascia...

Nonphysical contact between cagemates alleviates the social isolation syndrome in C57BL/6 male mice.
Abstract
We attempted to identify the contribution of the selective deprivation of physical contact to the emergence of the isolation syndrome. To this end, we devised a pseudoisolated housing condition in which male 3-week-old C57BL/6 mice were caged in pairs, but were separated by a transparent perforated...

Abstract
Ghrelin, an endogenous ligand for the growth-hormone-secretagogue receptor, is a 28-amino acid peptide with a post-translational acyl modification necessary for its activity. It has central nervous system actions that affect appetite, body mass and energy balance. An intracerebroventricular (ICV) in...

Oviposition in Delia platura (Diptera, Anthomyiidae): the role of volatile and contact cues of bean.
Abstract
We conclude that olfaction plays a major role when D. platura females are searching for oviposition sites. Volatile compounds released from germinating beans such as 4-hydroxy-4-methyl-2-pentanone, 1-hepten-3-one, 1-octen-3-ol, and 3-octanone should be considered as key compounds that mediate ovipos...

Abstract
Increased ingestion of ethanol by RIIbeta(-/-) mice is likely the result of altered PKA activity within neuronal pathways that control ethanol-consummatory behaviors. Conversely, the RIIbeta subunit of PKA appears not to play a critical role in neuronal pathways that regulate appetitive behaviors di...
