# Foraging behavior and locomotion of the invasive Argentine ant from winter aggregations

**Daniel A. Friedman, Deborah M. Gordon** (2018) · Entomology

## Instructions

Use this skill when working with topics related to **Argentine ant, Linepithema humile, invasive species, supercolony**.

When applying this skill:
1. Analyze invasive social insect ecology and supercolony dynamics
1. Understand chemical ecology of nestmate recognition via cuticular hydrocarbons
1. Evaluate genetic and behavioral mechanisms of invasion success

## Key Concepts

- **Argentine ant**
- **Linepithema humile**
- **invasive species**
- **supercolony**
- **nestmate recognition**
- **collective behavior**
- **chemical ecology**
- **cuticular hydrocarbons**

## Methods & Techniques

- Recorded foraging rates and walking speeds of three L. humile colonies over three 24-hour periods.
- Measured environmental conditions including temperature, humidity, and light levels.
- Analyzed the correlation between foraging activity and the presence of the native ant species Prenolepis imparis.
- Utilized mixed effect models to assess the relationships between environmental factors and ant behavior.

## Key Findings

- Colony foraging peaked between 10 and 15˚C, regardless of maximum daily temperature.
- Worker walking speed increased with temperature and decreased with humidity.
- Foraging activity was consistent throughout the day and night, with a predictable daily cycle.
- Heavy rain caused ants to aggregate in sheltered areas, halting foraging activity.

## Prerequisites

- Evolutionary biology and ecology fundamentals
- Social insect biology and colony organization
