Cascading effects of polyphenol-rich purple corn pericarp extract on pupal, adult, and offspring of tobacco hornworm (Manduca sexta L.) [PDF]
Communicative and Integrative Biology, 2020 A major bottleneck in the commercialization of plant-based pest management compounds is that the extraction methods are complex, time-consuming, and even highly expensive.

RNA Interference in the Tobacco Hornworm, Manduca sexta, Using Plastid-Encoded Long Double-Stranded RNA [PDF]
Frontiers in Plant Science, 2019 RNA interference (RNAi) is a promising method for controlling pest insects by silencing the expression of vital insect genes to interfere with development and physiology; however, certain insect Orders are resistant to this process. In this study, we set

Digestion-related proteins in the tobacco hornworm, Manduca sexta. [PDF]
Insect Biochem Mol Biol, 2020 Food digestion is vital for the survival and prosperity of insects. Research on insect digestive enzymes yields knowledge of their structure and function, and potential targets of antifeedants to control agricultural pests. While such enzymes from pest species are more relevant for inhibitor screening, a systematic analysis of their counterparts in a ...

Contrasting Roles of Cannabidiol as an Insecticide and Rescuing Agent for Ethanol–induced Death in the Tobacco Hornworm Manduca sexta [PDF]
Scientific Reports, 2019 Cannabis sativa, also known as marijuana or hemp, produces a non-psychoactive compound cannabidiol (CBD). To investigate the defensive role of CBD, a feeding preference assay was performed with tobacco hornworm Manduca sexta.

A Toll-Spätzle pathway in the tobacco hornworm, Manduca sexta. [PDF]
Insect Biochem Mol Biol, 2012 Insects synthesize a battery of antimicrobial peptides (AMPs) and expression of AMP genes is regulated by the Toll and Imd (immune deficiency) pathways in Drosophila melanogaster. Drosophila Toll pathway is activated after Spätzle (Spz) is cleaved by Spätzle processing enzyme (SPE) to release the active C-terminal C106 domain (DmSpz-C106), which then ...

Effects of high-fat diet on feeding and performance in the tobacco hornworm, Manduca sexta. [PDF]
Comp Biochem Physiol A Mol Integr Physiol, 2019 Nutritionally balanced diets are important for overall fitness. For insects, fat is vital for development due to its high-energy value. Little is known about how insects regulate dietary fat for storage, but research has shown conflicting results on how ...
