Hiding in Plain Sight: Cuticular Compound Profile Matching Conceals a Larval Tortoise Beetle in its Host Chemical Cloud
Larvae of tortoise beetles are postulated to have fecal shields as the main defensive strategy against predators. Such a device protects beetles both physically and chemically. In order to examineExpand

Are Aristolochic Acids Responsible for the Chemical Defence of Aposematic Larvae of Battus polydamas (L.) (Lepidoptera: Papilionidae)?
Aristolochic acids (AAs) are thought to be responsible for the chemical protection of the aposematic larvae Battus polydamas (L.) (Papilionidae: Troidini) against predators. These compounds areExpand

Ants visiting extrafloral nectaries and pyrrolizidine alkaloids may shape how a specialist herbivore feeds on its host plants
The presence of extrafloral nectaries (EFNs) attracts predators and parasitoids, and protects the plant against herbivorous insects. By improving plant defences, EFNs reduce the fitness ofExpand

Volatiles released by damaged leaves of Piper mollicomum (Piperaceae) act as cues for predaceous wasps: evidence using plasticine dummies as herbivore model
Volatiles released by damaged plants are used as cues by predators and parasitoids to find their herbivorous prey. Here, we assessed whether odor cues released by simulated herbivore-damaged leavesExpand
