A Wind Tunnel for Odor Mediated Insect Behavioural Assays

12.4K
Here, we describe the construction and use of a wind tunnel for odor mediated behavioural assays with insects. The wind tunnel design facilitates the release of odor sources by several methods, with and without visual stimuli. Wind tunnel experiments are important methods to identify behaviorally active volatile...

Osmoregulation in Insects01:47

Osmoregulation in Insects

17.5K
Malpighian tubules are specialized structures found in the digestive systems of many arthropods, including most insects, that handle excretion and osmoregulation. The tubules are typically arranged in pairs and have a convoluted structure that increases their surface area.

Administering and Detecting Protein Marks on Arthropods for Dispersal Research

7.8K
Proteins are often used to mark arthropods for dispersal research. Methods for administering internal and external protein marks on arthropods are demonstrated. Protein mark detection techniques, either through indirect or sandwich enzyme-linked immunosorbent assays (ELISAs), are also illustrated.

Distribution and Dispersion00:54

Distribution and Dispersion

24.1K
To understand intra-specific interactions in populations, scientists measure the spatial arrangement of species individuals. This geographic arrangement is known as the species distribution or dispersion. Highly territorial species exhibit a uniform distribution pattern, in which individuals are spaced at relatively equal distances from one another. Species that are highly tied to particular resources, such as food or shelter, tend to concentrate around those resources, and thus exhibit a...

Assessing Biofilm Dispersal in Murine Wounds

5.1K
Here, we describe ex vivo and in vivo methods for assessing bacterial dispersal from a wound infection in mice. This protocol can be utilized to test the efficacy of topical antimicrobial and anti-biofilm therapies, or to assess the dispersal capacity of different bacterial strains or species.

Summary
This summary is machine-generated.

Human activities drive biological invasions by introducing and spreading species. Decomposing human-mediated dispersal into departure, transport, and arrival phases reveals how species traits and human actions shape invasion pathways in insects.

Area of Science:

  • Ecology
  • Invasive Species Biology
  • Conservation Biology

Background:

  • Biological invasions pose significant ecological and economic threats globally.
  • Human activities are the primary drivers of species introductions and their spread beyond native ranges.
  • Understanding the mechanisms of human-mediated dispersal is critical for managing invasive species.

Purpose of the Study:

  • To analyze the influence of human activities and species traits on insect invasions.
  • To develop a framework for understanding human-mediated dispersal in three distinct temporal phases.
  • To improve the accuracy and applicability of invasion models for insect pests.

Main Methods:

  • Decomposition of human-mediated dispersal into departure, transport, and arrival phases.
  • Analysis of the interplay between human activity characteristics and species biological traits.
  • Integration of dispersal mechanisms into ecological invasion models.

Main Results:

  • The study demonstrates how distinct phases of dispersal are modulated by specific human activities and species traits.
  • A novel framework is presented for dissecting complex invasion pathways.
  • The research highlights variability in the distribution of invasive insects based on dispersal mechanisms.

Conclusions:

  • Understanding the temporal phases of dispersal enhances predictions of invasion pathways for insects.
  • The proposed framework can improve the realism and generalization of invasion models.
  • This approach provides insights into the success of invasive insects and aids in risk assessment for non-native species.
