...Kendra J. Greenlee; John J. Socha; Haleigh B. Eubanks; Paul Pedersen; Wah-Keat Lee; Scott D. Kirkton SUMMARY Abdominal pumping in caterpillars has only been documented during molting. Using synchrotron X-ray imaging in conjunction with high-speed flow-through respirometry, we show that Manduca...

... for climbing in complex branched structures and on a variety of surfaces. Caterpillars therefore are excellent for examining the relationship between soft body deformation and substrate reaction forces during locomotion. In this study, we devised a method to measure the ground reaction forces (GRFs...

...William A. Woods, Jr; Steven J. Fusillo; Barry A. Trimmer SUMMARY Caterpillars are soft-bodied terrestrial climbers that perform a wide variety of complex movements with several hundred muscles and a relatively small number of neurons. Control of movements is therefore expected to place unusual...

..., final-instar caterpillars of generalist-feeding African cotton leafworm Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) were confined to one of 20 diets varying in protein:carbohydrate (P:C) ratio (35:7, 28:14, 21:21,14:28 and 7:35) and in the quality of dietary protein (0%, 20%, 50% and 80...

...Sheri Mezoff; Nicole Papastathis; Anne Takesian; Barry A. Trimmer SUMMARY Caterpillars are ecologically successful soft-bodied climbers. They are able to grip tightly to foliage using cuticular hooks at the tips of specialized abdominal limbs called prolegs. The neural control of proleg retraction...
