Understanding insect flight patterns is crucial for managing invasive species. This study uses Bayesian networks to predict the flight activity of three exotic forest insects, informing phytosanitary risk assessments for wood exports.

Area of Science:

  • Forest entomology
  • Ecological modeling
  • Invasive species management

Background:

  • Insect flight activity is influenced by environmental factors like temperature and time.
  • Complex interactions between these factors are not fully understood.
  • Predicting insect flight is vital for assessing phytosanitary risks.

Purpose of the Study:

  • To develop Bayesian network models predicting the flight activity of three exotic forest insects: Hylurgus ligniperda, Hylastes ater, and Arhopalus ferus.
  • To identify key environmental drivers influencing the flight patterns of these species.
  • To inform phytosanitary risk assessments and targeted mitigation strategies for invasive species.

Main Methods:

  • Utilized 7,144 hours of insect sampling data combined with meteorological and temporal variables.

  • Constructed individual naïve Bayes tree augmented networks for each insect species.
  • Discretized meteorological and temporal variables for model input.

    • Main Results:

    • Bayesian network models showed good calibration for predicting insect flight activity.
    • Maximum hourly temperature and time since sunrise were key for H. ligniperda.
    • Time of day and year were most influential for H. ater and A. ferus.

    Conclusions:

    • Bayesian networks provide a robust framework for predicting exotic insect flight activity.
    • Understanding flight patterns aids in quantifying phytosanitary risks associated with wood exports.
    • Targeted mitigation can prevent the spread of invasive species through international trade.
