The biology of a newly discovered deathwatch beetle that infests one-year-old and older black spruce Picea mariana B.S.P. cones is described. This pest reduces the amount of seed retained in the cones that persist on the trees for many years. Up to 50% of a cone crop at a location may be damaged and annual damage between 1963 and 1979 averaged up to 18% for samples from 33 locations. Undamaged cones may not retain enough seed to naturally re-establish stands following harvest or fire. Substantial seed losses were observed when infested cones were harvested for seed extraction. This cone beetle has been recorded only from Newfoundland.

AbstractA small repository in a cathedral in Poland, storing severely damaged books, was investigated with regard to insects and fungi. Entomological and microbiological surveys were performed to estimate the extent of the infestation and the microbial deterioration of the books. Most of the books were attacked by insects although to varying degrees. They were damaged by tunnels bored by the larvae and filled with larval faeces. Some living larvae and many dead adult beetles were found in the books or in the frass. The larvae and most of the beetles were identified as the common deathwatch beetle Xestobium rufovillosum (DeGeer, 1774). The development of Xestobium rufovillosum in books is an unusual case and has rarely been mentioned in the literature. Several books in the repository were also covered by microfungi, especially by Chaetomium murorum, Ch. elatum, Myxotrichum chartarum, Stachybotrys atra and Epicoccum nigrum. The temperature in the repository varied, depending on the season of the year (2.6 °C – 26.2 °C), while the relative humidity was high (constantly above 65 %). The concentration of the fungal bioaerosol was very high (4,120 cfu/m3). The article includes a list of recommendations pertaining to the elimination of the microorganisms and insects.

A new species of the genus Dorcatoma Herbst (Coleoptera: Anobiidae) is described based on material from Latvia and Sweden, and recorded also for Poland. Dorcatoma janssoni n. sp. is very close in appearance to D. chrysomelina Sturm, but male genitalia and biology are different. Antennae and male and female genitalia are figured, and the biology of the new species is described. Dorcatoma ambjoerni Baranowski is removed from the synonymy of D. setosella Mulsant & Rey. A key is provided for the European species of the Dorcatoma chrysomelina-group.
