[On House-longhorn Beetle Hylotrupes bajulus (L.), (Col., Cerambycidae) in hardwood: Investigations with several hardwood-species, tests on activity of lignin components and Ginkgo biloba, observations on Hesperophanes]
1982 - IRG/WP 1144
Hylotrupes bajulus-larvae feed and develop in softwoods, hardwood acts as a feeding poison. The reason for this is still little known. According to literature some observations contradict this established opinion and the question was raised, whether the colour-strain scutifer (= lividus) is able to live in hardwood. Testing ten European and tropical hardwood-species (following the DIN-EN test proc...

Phytosanitary heat treatment of wood in a laboratory drying oven and, in a pilot-scale kiln using the house longhorn beetle (Hylotrupes bajulus) larvae as a model
2024 - IRG/WP 24-20722
International trade in wood products brings the risk of the movement of tree pests which can cause devasting ecosystem and economic damage. International phytosanitary guidelines were created to help countries that import wood products. Import requirements intend to minimize pest spreading. Thus, the ISPM 15 (International Standards for Phytosanitary Measures No. 15) which specifies the “Regulat...

Proposal for co-operative work. Testing the ability of accidentally introduced tropical insects to survive the cold season in Europe
1976 - IRG/WP 155
By hibernation-experiments in the past it was found that not only the low temperatures may become fatal by freezing. In some experiments we found indications that larvae died by starvation. For example Lyctus africanus-larvae did so in some years with a cold winter (mean above 0°C). If you like to take starvation as a reason for death into account it may be useful to withdraw pieces of infested w...

Supercooling points of Anobium punctatum, the common furniture beetle
1995 - IRG/WP 95-10120
Ice formation within the body of larvae of the common furniture beetle Anobium punctatum causes death of the larvae. Freezing can therefore be used as a means of eradication of the larvae in infested wood. To optimize the freezing process, knowledge of the temperatures sufficient to kill the larvae is essential. Ice formation is initiated by temperatures equaling the so-called supercooling point, ...
