BACKGROUND The authors explored how microcapsule size and brief exposure affected the bioavailability of five microencapsulated insecticide formulations, chlorpyrifos 23.1 g L(-1) CS (Detmol-PRO), chlorpyrifos 20 g L(-1) CS (Empire 20), fenitrothion 20 g L(-1) CS (Detmol-Mic), cyphenothrin 10 g L(-1) CS (Detmol-CAP) and diazinon 30 g L(-1) CS (Diacap), to(More)
The rate of population increase of three mite species, Acarus siro (L.), Lepidoglyphus destructor (Schrank) and Tyrophagus putrescentiae (Schrank), was studied on various types of barley and at various combinations of temperature and humidity. The mites were added into the chambers and incubated for 21 days on seven different kinds of barley coming from(More)
The aim of the study was to establish a model of the environmental fate of German cockroach (Blattella germanica L.) allergens Bla g 1 and Bla g 2 in feces under controlled and field conditions. Temporal decline (3, 6, and 9 mo) of allergens Bla g 1 and Bla g 2 in the feces protected from cleaning was measured under laboratory and experimental household(More)
Cryptolestes ferrugineus (Stephens, 1831) is an important insect pest of stored products. Due to its broad host range, short life cycle, and high reproductive capacity, this species has rapidly colonized temperate and tropical regions around the world. In this study, we isolated 18 novel polymorphic microsatellite loci from an enriched genomic library based(More)
BACKGROUND The authors investigated whether fluorescent pigment in thermoset melamine microcapsules incorporated into monitoring baits would be excreted in the faeces of wild house mice in a quantity and intensity that would be detectable by a human observer. RESULTS Experimental mice produced 24-116 UV-visible faecal pellets per 24 h; the mean dry weight(More)
This study represents the first European report of a risk assessment for the contamination of grain by roof rats’ (Rattus rattus L.) faeces in silo structures that have traditionally been considered to be rodent-contaminant proof. In this work, we estimated the rate and magnitude of grain and grain transport silo technology contamination by faeces of R.(More)
Currently hydrogen cyanide (HCN) is industrially produced in the Czech Republic (Lucebni zavody Draslovka Kolin) and is extensively used for Czech mill fumigation. Therefore we evaluated the potential of HCN fumigant for treatment of wooden transport packages (pallets). We tested the penetration of HCN trough wooden pallet materials using gas(More)
In this study, we evaluated phosphine efficacy against two strains of the confused flour beetle, Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae), one laboratory strain, with no previous exposure to phosphine, and one field strain, originated from the flour mill on which we performed the fumigation. The standard Detia Degesh Phosphine(More)
