This guide will help you identify the caterpillars eating your tomatoes, and offer you some options for controlling them. If you have tomatoes in your garden, then chances are good at some point that you will encounter tomato hornworms, a serious pest of tomatoes and other plants.

sexta caterpillars combine a suite of parameters that make them suitable for the study of fungal virulence.Tomato Horn worm Caterpillars: Identification and Control Notably, these animals are large enough for weight to provide a reliable and reproducible measure of fungal disease and to facilitate host tissue-specific expression analyses. Infected caterpillars can be rescued by treatment with antifungal drugs. Importantly, fungal burden can be assessed daily throughout the course of infection in a single caterpillar’s feces and hemolymph. These caterpillars can be maintained at 37☌, are suitable for injections with defined amounts of yeast cells, and are susceptible to the most threatening yeast pathogens, including C. To complement existing invertebrate host models, we developed fifth instar caterpillars of the Tobacco Hornworm moth Manduca sexta as a novel host model. While this is commonly done in mammalian models, which are afflicted by ethical and practical concerns, invertebrate models, such as wax moth larvae and nematodes have been introduced over the last two decades. It is thus imperative to study fungal virulence mechanisms, efficacy of antifungal drugs, and host response pathways. The two leading yeast pathogens of humans, Candida albicans and Cryptococcus neoformans, cause systemic infections in >1.4 million patients worldwide with mortality rates approaching 75%.
