Cockroach
- Coding of odour and space in the hemimetabolous insect Periplaneta americana
Summary: Selective labelling of the cockroach's antennal lobe output neurons shows that odour responses are stimulus specific and concentration dependent, and preserve information on the spatial structure of the stimulus.
- History-dependent perturbation response in limb muscle
Summary: Muscle response to rapid, identical strain perturbations is history dependent, but is captured by a viscoelastic model with memory; the data and model show that the muscle perturbation response depends on locomotor frequency.
- Thermal stress causes DNA damage and mortality in a tropical insect
Highlighted Article: Experiments in a tropical cockroach, Gromphadorinha coquereliana, show that cold stress does not cause lethal DNA damage, in comparison to freeze stress. Thus this species can be classified as moderately freezing tolerant.
- Electrical interactions between photoreceptors in the compound eye of Periplaneta americana
Summary: In the compound eye of the American cockroach, complex electrical interactions take place between green- and UV-sensitive photoreceptors in each ommatidium.
- The role of the cerebral ganglia in the venom-induced behavioral manipulation of cockroaches stung by the parasitoid jewel wasp
Summary: We show that venom injection by the jewel wasp to either the subesophageal ganglion or the central complex in the brain is, by itself, sufficient to induce a long-term hypokinetic state in its cockroach prey.
