Altering Social Cue Perception Impacts Honey Bee Aggression With Minimal Impacts On Aggression-Related Brain Gene Expression, James W. Harrison, Joseph H. Palmer, Clare C. Rittschof

Entomology Faculty Publications

Gene expression changes resulting from social interactions may give rise to long term behavioral change, or simply reflect the activity of neural circuitry associated with behavioral expression. In honey bees, social cues broadly modulate aggressive behavior and brain gene expression. Previous studies suggest that expression changes are limited to contexts in which social cues give rise to stable, relatively long-term changes in behavior. Here we use a traditional beekeeping approach that inhibits aggression, smoke exposure, to deprive individuals of aggression-inducing olfactory cues and evaluate whether behavioral changes occur in absence of expression variation in a set of four biomarker genes …

Sequential Social Experiences Interact To Modulate Aggression But Not Brain Gene Expression In The Honey Bee (Apis Mellifera), Clare C. Rittschof

Entomology Faculty Publications

Background: In highly structured societies, individuals behave flexibly and cooperatively in order to achieve a particular group-level outcome. However, even in social species, environmental inputs can have long lasting effects on individual behavior, and variable experiences can even result in consistent individual differences and constrained behavioral flexibility. Despite the fact that such constraints on behavior could have implications for behavioral optimization at the social group level, few studies have explored how social experiences accumulate over time, and the mechanistic basis of these effects. In the current study, I evaluate how sequential social experiences affect individual and group level aggressive phenotypes, …

Characterization Of Head Transcriptome And Analysis Of Gene Expression Involved In Caste Differentiation And Aggression In Odontotermes Formosanus (Shiraki), Qiuying Huang, Pengdong Sun, Xuguo Zhou, Chaoliang Lei

Entomology Faculty Publications

Background

The subterranean termite Odontotermes formosanus (Shiraki) is a serious insect pest of trees and dams in China. To date, very little is known about genomic or transcriptomic data for caste differentiation and aggression in O. formosanus. Hence, studies on transcriptome and gene expression profiling are helpful to better understand molecular basis underlying caste differentiation and aggressive behavior in O. formosanus.

Methodology and Principal Findings

Using the Illumina sequencing, we obtained more than 57 million sequencing reads derived from the heads of O. formosanus. These reads were assembled into 116,885 unique sequences (mean size = 536 bp). …
