The unique antimicrobial peptide repertoire of stick insects

Developmental & Comparative Immunology, 2020
The comparative analysis of innate immunity across different insect taxa has revealed unanticipated evolutionary plasticity, providing intriguing examples of immunity-related effector gene expansion and loss. Phasmatodea, the stick and leaf insects, is an order of hemimetabolous insects that can provide insight into ancestral innate immunity genes lost

Active tactile exploration and tactually induced turning in tethered walking stick insects.

Journal of Experimental Biology, 2022
Many animals use their tactile sense for active exploration and tactually guided behaviors like near-range orientation. In insects, tactile sensing is often intimately linked to locomotion, resulting in the orchestration of several concurrent active ...

Tight turns in stick insects

Journal of Comparative Physiology A, 2009
We investigated insects Carausius morosus walking whilst hanging upside down along a narrow 3 mm horizontal beam. At the end of the beam, the animal takes a 180 degrees turn. This is a difficult situation because substrate area is small and moves relative to the body during the turn. We investigated how leg movements are organised during this turn.

Stick Insects Walking Along Inclined Surfaces

Integrative and Comparative Biology, 2002
In the experiments stick insects walk on an inclined substrate such that the legs of one side of the body point uphill and the legs of the other side point downhill. In this situation the vertical axis of the body is rotated against the inclination of the substrate as if to compensate for the effect of substrate inclination.

On the Repeated Evolution of Parthenogenesis in Stick Insects.

Evolution; international journal of organic evolution
Female-producing parthenogenesis is widespread in stick insects. It can be either rare and spontaneous in sexual species, or range from facultative to obligate, the latter sometimes in interspecific hybrids.

Jumping in a winged stick insect

Journal of Experimental Biology, 2002
SUMMARYThe Thailand winged stick insect (Sipyloidea sp.) flees rapidly from a disturbance by jumping forwards when stimulated on the abdomen and backwards when stimulated on the head. The mechanisms underlying these fast movements were analysed by measuring movements of the body and legs from images captured at 250 Hz.A forward jump of both adults and ...
