The ability of Manduca moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less likely to be attacked by insects and other predators, and to avoid competing against other caterpillars of the same species for resources.

Building on previous work (Kessler et al., 2015), it is shown that long-tongued hawkmoths assess individual flowers by smelling floral odors with olfactory neurons on their proboscises, and that this close-range perception is crucial for successful pollination and foraging.

A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.

The sense of smell of female hawkmoths has evolved to find the intense odor of floral nectar sources as well as inconspicuous scents of oviposition sites within a complex olfactory landscape.

Floral scent and nectar are highly variable in natural populations and both traits can influence outcrossing rates differently for different pollinators and increase future herbivory.

The full-length structures of the mammalian nitric oxide receptor reveal the molecular activation steps and a binding site for the prototype of FDA-approved stimulators.

Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.

Electrophysiological and morphological identification of individual pheromone projection neurons in male moth reveals a coding system for optimizing mate search strategy, including computation of three female-produced signals in distinct protocerebral regions.

The western corn rootworm escapes biological control by entomopathogenic nematodes by partitioning and phenocopying the plant defense system for self-protection.
