Transcriptional control of behaviour: engrailed knockout changes cockroach escape trajectories [PDF]

open access: yes, 2009
The cerci of the cockroach are covered with identified sensory hairs that detect air movements. The sensory neurons that innervate these hairs synapse with giant interneurons in the terminal ganglion that in turn synapse with interneurons and leg motor ...

A Comparison of Three Approaches for Larval Instar Separation in Insects—A Case Study of Dendrolimus pini

open access: yesInsects, 2019
The number of larval instars is important from both theoretical and practical perspectives. Three previous studies based on head capsule widths (HCWs) have suggested that Dendrolimus pini larvae pass through seven instars, but the estimated HCW means ...
