The common bed bug (Cimex lectularius L.) has recently surged in numbers internationally. A variety of plant-based, or “natural”, products that are stated to kill or repel bed bugs are being marketed directly to consumers, even though the efficac

Few studies have addressed the efficacy of insecticides used against eggs and first-instar nymphs of the bed bug, Cimex lectularius L. (Hemiptera: Cimicidae). Insect eggs are often resistant to insecticides; therefore, information on which products a

Two separate experiments were conducted to determine the transfer of E. coli by fruit flies during short term exposure to apple slices and bologna. Short time exposure (1, 5 and 15 min) of flies to inoculated apple slices were tested in the first exp

The paper identifies the significance of continuity between panels in a multi-panel composite floor. It examines dynamic behaviour through a comparison of the results from a forced vibration test, an eigenvalue analysis and a simulated sweeping test

We observed that teneral adults (72 h), and sclerotized group 2 (S2) bed bugs (n = 30, height climbed = 2.64 cm at >72 h post molt). When heights from all climbing events were summed, teneral bed bugs (650.8 cm climbed) differed significantly (P< 0.0

The Argentine ant, Linepithema humile (Mayr), is a pest in many urban areas of the southeastern United States. In the Piedmont region of South Carolina, there is a documented problem with L. humile invading the campsites of state park campgrounds. Wh

This paper considers the problem of human acceptance of vibration in grandstands. It adopts the BS frequency weighting methodology and uses the vibration dose value (VDV) as an indication of when adverse comments may be expected. Measurements were ta

This paper considers the significance of vertical loads that can produce horizontal movements of frame structures. It is shown that, with a small number of exceptions, vertical loads can induce horizontal movements of symmetric, antisymmetric and asy

This paper provides an overview of the response of grandstands to dynamic crowd loading. It summarizes the guidance which is currently available in the UK and how it has been developed. The interaction between structures and crowds is then considered

This paper considers four laser systems used by the Building Research Establishment (BRE) to investigate the behaviour of structures. Lasers enable remote measurements of vibration and displacement to be taken where access to a structure is difficult
