[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...
A rearing procedure for the house longhorn beetle Hylotrupes bajulus L
1973 - IRG/WP 228
The technique practised at the Princes Risborough Laboratory for culturing Hylotrupes bajulus is described. It is modified from methods previously suggested by German workers. A protein and vitamin enriched wood diet to accelerate larval growth is employed and larvae are subsequently given a period of cool storage to induce pupation. Adults are confined in groups with prepared surfaces for egg lay...

Threshold levels for dip treatments of chlorpyrifos for borer control
1995 - IRG/WP 95-10137
Chlorpyrifos has been used in non-pressure treatments of freshly sawn lumber and millwork for ten years or longer to control wood boring beetles. Since chlorpyrifos provides a quick kill of existing beetle larvae at the time of the treatment in solution concentrations as low as 0.05%, treaters tend to use less than recommended rates as a cost saving measure. However, laboratory studies conducted i...

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, ...
