The objective of the research presented here was to evaluate the impact of the introduction of a toxic food bait on foraging choice by the German cockroach, Blattella germanica (L.). This was done by analysing the importance of learning visual cues associated with feeding sites and the importance of...

Control of cockroach populations in urban environments is now very often performed with insecticides presented in food bait formulations. To be efficient, food baits must attract pests so that contact is made with the active substance and/or that it is ingested. Food baits may be less efficient for ...

The aim of this study was to investigate food bait preference in Blattella germanica (L.) cockroaches in relation to age and to compare their feeding preferences in several choice situations. Food choice presents two components: attractiveness measured by food type eaten first and feeding stimulatio...

German cockroaches, Blattella germanica (L.), live in aggregates and are able to return to their resting sites. Stability of aggregates is ensured both by individual navigation abilities and by conspecific recognition. Naviga tion capacities (estimated by orientation angle of escape direction and by...
