  1. Federal Research and Training Centre for Forest, Natural Hazards and Landscape / Vienna, AustriaLjubljana February 18th – 21st 2013Biacoustic Detection of Anoplophora glabripennisMonochamus galloprovincialisand Rhynchophorus ferrugineus

  2. Main Goals • Create a representative sound database • Create an inventory of sound types • Compile descriptive statistics of bioacousticproperties for all sound types • Test automaticspecies identification • Elaborate a real world bioacoustic test

  3. Methods Hardware • Assembling of contact microphones, preamplifiers, wiring • Assembling of PC-based recording system, Testing of soundcards and solid state recorders • Construction of sound proof recording box at BfW lab Animals • Collection of infested wood • Breeding of larvae Field work • Creation of recordings (field + lab) in various countries • Preprocessing, normalization & standardization of sound files Bioacoustic analysis • Basic inventarization of sounds • Annotation of sound events (machine + manual) • Spectrographic analysis, analysis of pulse repetition rates, etc. • Compilation of descriptive statistics (Sound Recognition Lab 2.0 Sejona R&D) • Species specific clustering of sounds Practical • Development of testing procedure

  4. I. Sound Collection • ALB: Italy (Field) • RPW: Israel (Lab+Field), Bari (Field) • Monochamus: BfW-Lab, Portugal (Field) • Contact Microphones (Elektret 0-16 kHz) • Preamplifiers (0-150 kHz) • Marantz PMD661 • PC-based HDRS with external soundcard

  5. II. Sound Inventory • ALB: breathing, feeding, moving • RPW: breathing, feeding, moving, knocking, chirps • MON: knocking, feeding, stridulation

  6. III. Properties of Sounds • Feeding sounds are loud and frequent → useful for detection in early stages of infestation • Communication sounds have sharp signatures → species identification!

  7. IV. Species Identification • Species can be identified acoustically • Accuracy depends on size of audio file collection

  8. Small and MediumTrees • Attach microphone • Create measurement series • Transfer data to computer • Extraction of suspicious sounds • Comparison with sounds in our database • Creation of measurement report 4. Positive result: • Extract larvae & verify (Visual, DNA-Test)

  9. Containers, Lorries etc. • Insert long polewithmicrophones attached • … same procedure …

  10. Check your trees! • Receive hardware + instructions • Training (optional) • Record your trees (up to 3 weeks) • Upload sound files • We will conduct a detailed bioacoustic analysis • Get results via email Positive result: • Extract larvae & verify result (Visual, DNA-Test)
