Anoplophora glabripennis (Cerambycidae) TheAsianlonghornbeetleattacksmainlyhealthytrees. Hostsincludebroadleaftreespecies, mostlymaple, butalsobeech, horsechestnut, poplar, birch, willowetc. Females tend to live longer than males, 14-66 days compared to 3-50 days respectively.ALB may have one or two generations per year. Theycan overwinter as an egg, larva or pupa. ALB fly for 2 to 3 days after emergence while mating and feeding. Adult ALB are usuallypresent from May to October. A single female can lay 30 to 70 eggs in her lifetime. After 10-15 days, the eggs hatch and the larvae tunnel into the wood. The adults burrow out of the tree, leaving round exit holes 6-18 mm in diameter. adult larva damage caused by larvae exit holes of adults damage caused by feeding adults www.invasive.org/gist/photos/ Q-Detect EPPO Workshop, Ljubljana, Slovenia, February 2013
The pine sawyer Monochamus galloprovincialis (Coleoptera: Cerambycidae) Monochamusbeetleattacksmainlyweakened trees, but when abundant it can also attack healthy trees weakened by the complementary feeding of adults and incisions made by females. Heavy larval feeding causes the death of trees and lowers the timber value. Monochamusgalloprovincialisis the vector of the pathogenic nematode Bursaphelenchusxylophilus. Insects require 10 to 13 months to develop and have a single generation per year. The emergence occurs from May to September with a peak in July. Females lay eggs from May to August and the young larvae have an extremely fast development before tunneling into the xylem, where they overwinter. adult vectorfor a pinewilt nematode, Bursaphelenchusxylophilus larva whichcausespinewiltdisease: damagecausedbylarvae Q-Detect EPPO Workshop, Ljubljana, Slovenia, February 2013
Rhynchophorus ferrugineus (Coleoptera: Curculionidae) The red palm weevil Preferredhosts: canarydate palm date palm andcoconut palm. Severalgenerationsoflarvae maybepresent in one palm tree; the RPW will not leavethe palm as long as there is stillenough foodforthedeveloping larvae. While the adults cause some damage through feeding, it is the burrowing of the larva into the heart of the palm that can cause the greatest mortality.Severallifecyclesmay becompleted in one year, depending on theclimate. adult life cycle larva palm tree dying off due to RPW infestation the base of leaf attacked by the RPW cocoon Q-Detect EPPO Workshop, Ljubljana, Slovenia, February 2013
OTHER POSSIBLE SOURCES OF LARVAL SOUNDS – BREATHING, SCRAPING MANDIBLES AGAINST THE BARK, STRIDULATION? Soundproduction in larvaeofCerambycidaeis a rarephenomenondescribed in onlyfewspecies. Larvaeprobablyemitthesoundsbythescratchingof mandiblesagainstthegallerywalls (or knockingofthe headagainstthewalloflarvalburrow) (Kočárek, 2009; VictorssonandWikars, 1996; Izumi etal., 1990). Why do we do it? • sounds directed to the larvae of the • same species for the purpose of holding together or expressing claim of space; • helps the larva secure resources by keeping away other potentially competitive larvae (canibalistic behaviour among larvae of M. sutor when placed in close contact confirmed this assumtion). No mention of larval stridulation in either Curculionidae or Cerambycidae family found in the literature.

Advantages/ disadvantagesofthe laser vibrometercompared to themicrophone • Contraryto accelerometers, microphones or other bioacousticsensors,laservibrometers are completely non-contact and as suchare not affected by theproperties of the test surface.Zeroloadingofthe test surface alsomeansthatthemechanicalproperties of themeasurementsurfaceare notmodified in anywayduring therecording. • Microphones, forexample, lack a completecouplingwiththe substrate andthereforedetectalsotheairbornecomponentofheemittedstructure-borne signals. Theydemandamplification → thesignalsthat are picked up are inevitablymaskedbytheenvironmentalairbornenoise. • Thelaser vibrometer, however, recordsonly substrate-borne vibrations. • LVis characterized by high sensitivity and a broad frequency range between 0 and 22 kHz, • robustness and • a working distance of several meters to the tested surface, which expands recording posibilities in relation to previously used acoustic methods for detection of wood boring insects. PDV-100 ideal foruse in thefield: - lightweight (2.6 kg) portable laser vibrometers, - veryrobust - 4h battery time disadvantage: laservibrometers are expensive but with their wide use in measurementswhereconventional sensors may be difficult or impossible, their price is decreasing and they willbecomemore and more accessiblefor use in science and applications.

Lucanus cervus (stag beetle) LARVAL STRIDULATION The stridulatory apparatus of stag beetle larvae consists of a pars stridens (file) on the coxae on the middle legs and a plectrum (scraper) on the trochanter of the hind legs. The larvae rub these parts, in their middle and hind legs, together to produce a sound. The sound is a very short rattle, repeated once or twice. It lasts ca. 1 second and the sound frequency is about 11 kHz. http://maria.fremlin.de/stagbeetles/stridulation.html
