- 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.
