Ecological consequences of genetic variation in foraging behaviors of a predatory mite
… predator dispersal and aggregation in response to prey-induced volatile cues becomes more critical. My dissertation addressed predator-prey population dynamics in response to variation in four foraging traits in the predatory mite, Phytoseiulus persimilis (Acari: Phytoseiidae): …

Odorant receptors: regulation, signaling, and expression
Olfactory signal transduction is initiated by binding of odorous ligands to G protein-coupled odorant receptors, resulting in the activation of G protein and second messengers that culminates in the generation of action potentials to relay this signal to the brain for odor recognition. This …

Chemical Manipulation of Honey Bee Behavior
… recordings were conducted to verify an olfactory response of the bees to the tested compounds. Pheromonal compounds were readily detected by bee antennae; whereas, the HCAs did not elicit significant responses in the bee antennae. These data suggest that bee pheromonal compounds, as well …

Two Odorant-Binding Protein Genes in Mosquitoes: Comparative Genomics, Expression, and Function
… transport them to their cognate receptors in the olfactory receptor neurons. With the availability of the genome sequence of the African malaria mosquito, Anopheles gambiae, there has been a profound interest in the characterization and functional analyses of Obp genes in order to understand the …

Deep Brain Stimulation to Increase Generalized Arousal in Intact Mice and a Mouse Model of Traumatic Brain Injury
… here: motor activity and sensory (specifically olfactory) responsiveness. In addition to the question of the effectiveness of CT/DBS to increase generalized arousal, this thesis explores the efficiency of a small set of parameters of stimulation. The data presented in this thesis show that 1) …

Studies of the mechanisms involved in host finding and mating behaviour of the African coffee white stem borer, Monochamus leuconotus (pascoe) (Cleoptera: Cerambycidae)
… to dead females washed with hexane, and the responses could be partially restored by recoating the washed females with the hexane washings, indicating that cuticular hydrocarbons are important for recognition of sex and species. A laboratory bioassay was developed for evaluating the olfactory …

Drosophila melanogaster Genetic Model of Parkinson’s Disease: phytotherapy approach for a new and more sustainable pre-clinical investigation
… considered were lifespan, motor activity, olfactory response, synaptic protein expression, mitochondria and synaptic active zone morphology; both in treated and untreated flies. The overall results indicate that Mpe shows a significant effect on PINK1B9 mutants while Wse acts mostly on …

Meccanismi di difesa e interazioni multitrofiche tra Solanum spp. e Tuta absoluta
La conoscenza delle interazioni pianta-insetto e della resistenza delle piante rappresenta un'opzione chiave di controllo per ottimizzare la gestione sostenibile e integrata dei parassiti e quindi per ridurre l’uso degli insetticidi. Le piante sono in grado di rispondere agli stress abiotici e …
