The Powers of Survival of Storage and Domestic Pests under Winter Conditions in Britain

Abstract

In order to test their ability to survive the winter in unheated buildings, 68 species of storage and domestic insect pests were exposed throughout one or more winters in wooden screens and various outbuildings at the Pest Infestation Laboratory, Slough, Bucks.Generally, cultures containing all developmental stages were exposed. The chief aim was to demonstrate some survival or else the complete failure of the culture; conclusionsabout single stages were added where possible.The ability or failure of a species to overwinter may be affected by the following factors, which are discussed: cold-hardiness, effects of previous conditions, differences between strains or races within a species, severity of the winter, length of period of exposure, moisture conditions, type of building, protection by materials in storage, biological heating of the immediate environment.The shortest experiment lasted 16 days, the majority for about six months.

The Insect and Mite Fauna of a Scottish Flour Mill

“…From observations carried out in the unheated sections of this mill it would appear that Endrosis sarcitrella, Tipnus unicolor and Cryptophagus cellaris might safely be included in the list of " hardy " insects, able to survive the winter in unheated buildings. This is in agreement with the results obtained by O'Farrell & Butler (1948) (as quoted by Solomon & Adamson (1955), who did not study these species). It is suspected that both E. sarcitrella and T. unicolor overwinter in larval form whilst G. cellaris may do so in either adult or larval form.…”

“…cornutus and T. confusum both inhabited milling machinery where temperatures were higher than elsewhere in the flour-milling section. These two species are considered by Solomon & Adamson (1955) to be, respectively, very susceptible and moderately susceptible to low-temperature conditions such as normally exist during winter in Britain. This may explain their failure to become established in the unheated sections of this flour mill, and their absence from the empty granary studied by Coombs & Freeman. Ephestia kuehniella, however, has been found capable of withstanding winter conditions and this appears to be confirmed by its ready establishment in the unheated sections of this flour mill.…”

Thatch, Turves and Floor Deposits: a Survey of Coleoptera in Materials from Abandoned Hebridean Blackhouses and the implications for their Visibility in the Archaeological Record

“…These Ptinidae are familiar inhabitants of dry materials in store houses (Howe & Burges, 1951;Coombes & Freeman, 1956;Salmond, 1957;Hunter et al, 1973). The two species seen here are believed to be the only synanthropic ptinids that occur outside of heated storehouses and are regarded as ''hardy'' (Solomon & Adamson, 1956). Both are thought to have a greater tolerance for low temperatures and dampness than the other synanthropic species from this family (Hunter et al, 1973;Coombes & Freeman, 1956).…”

Ocorrência de coleópteros em alimentos industrializados para cães, comercializados na região metropolitana de Recife, PE

“…No Reino Unido e na Itália, O. surinamensis, T. castaneum e R. dominica têm sido relatadas infestando grãos armazenados a granel e produtos acondicionados em embalagens fechadas (Solomon & Adamson 1995, Trematerra et al 2000, Cox & Collins 2002. Essas duas espécies têm sido encontradas na Austrália em fazendas onde predominam o cultivo de cereais como aveia e trigo (Sinclair 1982).…”

“…Esse resultado é similar àqueles observados por Arbogast (1991) sobre baixa freqüência desses coleópteros em produtos armazenados a granel em varejos nos Estados Unidos. No estágio adulto, L. serricorne é capaz de perfurar embalagem plástica de produtos alimentícios, causando sérios problemas na comercialização (Arbogast et al 2005 (Solomon & Adamson 1995). Ainda que a habilidade de vôo de R. dominica (Leos-Martinez et al 1986) pudesse permitir a essa espécie maior dispersão entre os produtos comercializados abertos (Trematerra et al 2004), ela tem sido encontrada em baixa freqüência.…”
