Teaching About Behavior with the Tobacco Hornworm
The American Biology Teacher, 2001 Overcrowding of a species is often its undoing. Competition for limited resources, spread of disease, and behavioral changes lead to death or severe stress that ultimately reduces the population. This important biological principle is not easily demonstrated in the classroom since a reasonably large population of easily viewed organisms must be ...

DNA insecticides based on iap3 gene fragments of cabbage looper and gypsy moth nuclear polyhedrosis viruses show selectivity for non-target insects [PDF]
Archives of Biological Sciences, 2015 DNA insecticides are novel preparations based on short single-stranded fragments of anti-apoptotic (IAP) genes of nuclear polyhedrosis viruses. In this article we report about the harmlessness of the DNA insecticides based on single-stranded ...

A quantitative micro-tomographic gut atlas of the lepidopteran model insect Manduca sexta
iScience, 2023 Summary: The tobacco hornworm is used extensively as a model system for ecotoxicology, immunology and gut physiology. Here, we established a micro-computed tomography approach based on the oral application of the clinical contrast agent iodixanol ...

Intraspecific combinations of flower and leaf volatiles act together in attracting hawkmoth pollinators. [PDF]
PLoS ONE, 2013 Insects pinpoint mates, food and oviposition sites by olfactory cues. Recognizing and localizing a suitable target by olfaction is demanding. Odor sources emit characteristic blends of compounds that have to be identified against an environmentally ...

Apolipophorin-III mediates antiplasmodial epithelial responses in Anopheles gambiae (G3) mosquitoes. [PDF]
PLoS ONE, 2010 Apolipophorin-III (ApoLp-III) is known to play an important role in lipid transport and innate immunity in lepidopteran insects. However, there is no evidence of involvement of ApoLp-IIIs in the immune responses of dipteran insects such as Drosophila and
