Repellents are biocides and a proof of efficacy is required for active substance inclusion as well as for product authorization. Here, we describe two test systems for efficacy evaluation of ant repellents with the substances DEET 50 %, Margosa extracts 100 %, baking powder: sodium hydrogen carbonat...

The development of resistance against insecticides, which are primarily used for bed bug (Cimex lectularius) control, is considered to one of the main reasons for the worldwide expansion of this pest. This study provides evidence of the occurrence of resistance and the mechanisms associated with a d...

In the European Union, baits against pharaoh ants (Monomorium pharaonis) have to be authorized as biocidal products. The dossier to be submitted for authorization of the product has to include a proof of product efficacy. No consistent test standards have been established by the European Commission....

Pyrethroid-resistance in bed bugs, Cimex lectularius, has been described in many countries, but up to now, for Germany no data are available. However, pest control companies increasingly report difficulties in controlling bed bugs with pyrethroids. In the present study four bed bug strains were coll...

In a semi natural test system for efficacy evaluation of rodenticidal products according to the Infectious Diseases Protection Act of the Federal Republic of Germany, 80 choice tests with Mus musculus and 62 choice tests with Rattus norvegicus from 1984 to 2010 were evaluated. The tests were conduct...

Exploitation of very high or low temperatures for bed bug, Cimex lectularius, control can be a supporting measure or even an alternative to chemical control methods. To observe the influence of heat, groups of adults, juveniles and eggs (group size = 20 individuals) were exposed to ambient temperatu...

The German cockroach (Blattella germanica) is host for several parasites. Due to the high population density in laboratory cultures of cockroaches, transmission rates of parasites as well as parasite prevalence can also be high. Cockroaches are important test organisms for efficacy testing of insect...

The use of bait in a bait station may significantly alter bait acceptance, and consequently its efficacy for rodent control. Here, we describe a method for efficacy testing of rodent bait stations under laboratory conditions. Bait stations are tested in an experimental setup of three test chambers (...

In order to elucidate the role of temperature as a crucial survival factor for human body lice (Pediculus humanus humanus), we investigated the influence of different temperature regimes on survival of adult lice after their last blood meal as well as on oviposition and egg hatch rates. The Federal ...
