Path selection in cockroaches.
In gregarious insects, the exploration and the use of the home range can involve both individual navigational abilities and/or chemical trails. Trail formation can result from an active laying of pheromones but can also derive from the incidental deposition of chemical cues. In this study, we investigated whether scent trails can influence path selection in the cockroach Blattella germanica (L....
متن کاملProprioceptive leg reflexes in cockroaches.
Proprioceptive feedback from the moving wings of locusts contains information which could be sufficient for the control of the timing of the wing-muscle contractions. It has been found, however, that at the high frequency of limb movement used in flight this phasic information content is lost in the ganglionic transfer (Wilson & Gettrup, 1963). During rapid running the legs of cockroaches also ...
متن کاملSelf-organized aggregation in cockroaches
Aggregation is widespread in invertebrate societies and can appear in response to environmental heterogeneities or by attraction between individuals. We performed experiments with cockroach, Blattella germanica, larvae in a homogeneous environment to investigate the influence of interactions between individuals on aggregations. Different densities were tested. A first phase led to radial disper...
متن کاملFleas, Caterpillars and Cockroaches
There is no doubt that the coming decades will see a continued increase in the application of robotics in our daily lives. It is vital that we encourage more young people to pursue careers in STEM fields and in particular, robotics. Universities can play their part by running events that allow participants to explore the field of robotics through hands-on projects. In this paper our experiences...
متن کاملFlavobacteria as intracellular symbionts in cockroaches.
Animal cells are the sole habitat for a variety of bacteria. Molecular sequence data have been used to position a number of these intracellular microorganisms in the overall scheme of eubacterial evolution. Most of them have been classified as proteobacteria or chlamydiae. Here we present molecular evidence placing an intracellular symbiont among the flavobacteria-bacteroides. This microorganis...
