January: Search Based On Social Insect Behavior
… pattern is a semi-random walk based on the behavior of the grey field slug (Agriolimax reticulatus), the house fly (Musca domestica), and the black ant (Lassius niger). The agents communicate to lessen the amount of duplicate work being done. Every algorithm has a memory threshold above …

Obstacle Navigation Decision-Making: Modeling Insect Behavior for Robot Autonomy
… that this algorithm can be extended to predict behavior of cockroaches in arenas with clear barriers between the entrance and the goal. For robotics, this algorithm could add some variability to robot paths in situations where heuristics fail. For biology, this algorithm is a model that may help …

Investigating post-harvest insect-microbe interactions and their ramifications for global food quality, human health, and insect behavior
… for microbes across time, 2) elucidate the behavioral response of each species to microbially mediated volatile emissions in grain, and 3) determine how foraging preferences affect development and fitness among habitats of different quality by each species. To assess the vectoring capacity, …

Interaction Between Insects and Apple (Malus X Domestica Borkh.): Insect Behavior, Genotypic Preference, and Plant Phenolics With Emphasis on Japanese Beetle (Popillia Japonica Newman)
… x domestica Borkh.) genotypes were evaluated for insect injury in 1998 and 1999. Foliar and fruit injury from 12 insect species was inconsistently affected by genotype. Spraying trees with oil affected neither fruit insect injury nor fruit phytotoxicity. In choice feeding assays, incidence of …

An improved artificial bee colony algorithm for training multilayer perceptron in time series prediction
… Bee Colony (ABC) algorithms built on the social insect behavior are proposed in this research for training ANN, namely the widely used Multilayer Perceptron (MLP). Here, three improved learning approaches inspired by artificial honey bee's behavior are used to train MLP. They are: Global Guided …

Life on a Ball: Multi-Week Tethered Behavior in Drosophila
… to make high-resolution neurophysiological and behavioral measurements during naturalistic tasks. Tethered paradigms have a particularly rich history in the study of insect behavior and in this thesis I describe technology that extends by one-hundred fold—from hours to weeks—the timescale over …

Map-Building and Position Estimation in Mobile Robots Using Self-Organizing Maps
… basic environmental hazards. Recent studies of insect behavior and navigation reveal a number of elegant strategies that can be valuable when applied to the design of autonomous robots, without the need for higher level cognitive processes such as object identification and labelling. These …

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, …

Use of sensory information by cerambycids and their natural enemies to locate resources and mates
The purpose of this dissertation is to extend knowledge of the cues and signals that cerambycids and their natural enemies use to locate mates and resources. Many species of longhorned beetles (Coleoptera: Cerambycidae) prefer to feed in trees that are stressed, weakened, or in the process of …
