Investigations into insect chemistry
… Chem. Internat. Edit., 12</em>, p. 644). The insect kingdom has been the subject of the most intense work and it has now been revealed that many facets of insect behavior are governed by chemical stimuli.</p> <p>The name “pheromone” is derived from the Greek <em>pherein</em> (to bear, …

Insect brain modeling for cognitive robotics
… lines: the first one has been directed to the insect brain modeling; the second line has been oriented to the simulation and the implementation of the model in robotic structures and then to the analysis of the behavior of the robots in order to obtain comparative results with real flies as …

Micromechanical actuators for insect flight mechanics
… to develop MEMS actuators to aid in the study of insect flight mechanics. Specifically, we are developing actuators that can stimulate the antennae of the crepuscular hawk moth Manduca Sexta. The possible mechanosensory function of antennae as airflow sensors has been suggested, and recent …

Material Characterization of Insect Tracheal Tubes
The insect respiratory system serves as a model for both robust microfluidic transport and mate- rial design. In the system, the convective flow of gas is driven through local deformations of the tracheal network, a phenomenon that is dependent on the unique structure and material properties of the …

Investigating post-harvest insect-microbe interactions and their ramifications for global food quality, human health, and insect behavior
… by S. oryzae and L. serricorne were performed. Insects were released into the dispersal apparatus with habitats located at opposite ends. Our study found that microbes modulated the preference and progeny production of L. serricorne, which dispersed to the uninfested habitats, while S. oryzae …

Structure-Function Analysis of Insect Olfactory Receptors
… into an internal representation of the world. Insects employ their keen sense of smell for a variety of tasks including location of food sources, which can vary from yeast growing on ripe fruits for the vinegar fly Drosophila melanogaster to mammals for blood-feeding insects such as the …

Disrupting insect-mediated transmission of plant viruses
… which virus particles are transported on these insects’ specialised piercing mouthparts (stylets). Virus infection can change plant-vector interactions and it is thought that this may accelerate virus transmission. To better understand how to inhibit virus transmission, I studied vectoring of …

January: Search Based On Social Insect Behavior
January is a group of interacting stateless model checkers. Each agent functions on a processor located on a super computer or a network of workstations (NOW). The agent's search pattern is a semi-random walk based on the behavior of the grey field slug (Agriolimax reticulatus), the house fly …

Biologically-inspired control framework for insect animation.
Insects are common in our world, such as ants, spiders, cockroaches etc. Virtual representations of them have wide applications in Virtual Reality (VR), video games and films. Compared with the large volume of works in biped animation, the problem of insect animation was less explored. Their small …

Molecular pharmacology of an insect GABA receptor
… melanogaster and is a major target site for insecticides. The aim of this dissertation was to characterise RDL receptors with particular focus on the agonist binding site. To assess the potency of a range of GABA analogues on RDL receptors, I expressed receptors in Xenopus oocytes and used …

Butterflies fly away: insect decline in California, USA
… sensational study documenting reductions of insect biomass from protected areas in Germany, reports of insect decline have become common across the world. While some patterns have emerged, such as a 2% annual rate of decline in temperate terrestrial insects, many questions remain, including …

Structural and Physical Characterization of Insect Flow Systems
… geometry, kinematics, and physical properties of insect internal structures that make up the respiratory and circulatory systems. This characterization is necessary to better understand how these systems function to transport fluids at the microscale, and ultimately, how we might computationally …

The Biotechnological Applications of an Insect-Specific Alphavirus
… and classification of a growing number of novel insect-specific viruses (ISVs). These viruses appear to be evolutionarily related to many human pathogens but have either lost or have yet to gain the ability to replicate in vertebrates. The discovery of ISVs has raised many questions as to the …

Biomechanical and neurophysiological investigation of insect tympanal organs
Investigating how insects receive sound via the structure of their auditory organs could inspire new, more sensitive, acoustic sensor systems to be developed, where the insect hearing organs that have previously been documented are believed to be more sensitive than any man-made devices that can …

Intraspecific plant polyploidy effects on goldenrod insect herbivores

A Neuroethology Approach For Insect Senses And Behavior
Neuroethology is the study of neural basis of natural behavior. I studied learning using sound as a cue in fruit flies and made recordings from the Johnston's organ (JO), I also investigated associative learning in mosquitoes. Finally, I studied Salticid (jumping) spiders to investigate the neural …
