Plant–Insect Interactions

Research in plant–insect interactions at CECE explores the sophisticated chemical dialogues that shape the relationships between plants and herbivorous insects. We investigate how plants emit specific volatile blends, surface chemicals, and defensive compounds in response to insect feeding, and how insects decode these cues to locate hosts, avoid unsuitable plants, or overcome plant defenses. By integrating molecular, behavioral, and chemical approaches, this research uncovers the evolutionary arms race between plants and insects and reveals the biochemical strategies that underpin ecological resilience and adaptation.

Predator–Prey Interactions

Our work on predator–prey interactions focuses on the chemical signals that mediate detection, avoidance, and survival across trophic levels. CECE researchers study how predators track their prey using olfactory cues and how prey species evolve chemical defenses or deceptive signals to evade predation. Through laboratory and field-based experiments, we aim to understand the chemical basis of these interactions and how they shape community dynamics, ecological stability, and the evolutionary trajectories of both predators and prey.

Microbial Ecology

CECE investigates the central role of microorganisms in the ecology and fitness of both plants and insects. Our research examines microbial communities associated with roots, leaves, insect guts, and external structures, identifying how these microbes produce bioactive compounds that influence nutrition, immunity, behaviour, and host–microbe co-evolution. By decoding the chemical signals exchanged among microbes, plants, and insects, we aim to reveal their contributions to health, defense, symbiosis, and ecological specialization.

Applied Chemical Ecology

Applied chemical ecology at CECE translates fundamental discoveries into innovative, sustainable solutions for agriculture and environmental management. Focusing on pheromones, kairomones, repellents, attractants, and other semiochemicals, our research develops ecologically compatible strategies for pest monitoring, behaviour modification, and crop protection. This work bridges basic science with field implementation, contributing to reduced pesticide dependence and the promotion of resilient, environmentally responsible agricultural systems.

Pollinator Chemical Ecology

Our research in pollinator chemical ecology investigates the chemical cues that guide pollinators to flowers, influence their foraging decisions, and structure plant–pollinator networks. CECE studies floral volatiles, nectar chemistry, and pollinator sensory physiology to understand how plants attract and reward pollinators and how pollinators navigate complex chemical landscapes. These insights support conservation of pollinators, enhancement of crop pollination, and a deeper understanding of how chemical signals maintain ecological balance.

Neuroethology

The neuroethology program at CECE focuses on how insects and other organisms perceive, process, and respond to chemical information at the neural level. By combining electrophysiology, neuroimaging, genomics, and behavioral assays, our research uncovers how odorants and tastants are encoded by sensory systems and transformed into instinctive or learned behaviours. Through this lens, we aim to understand the neural circuits underlying host selection, mating, foraging, and predator avoidance, linking chemical cues directly to ecological outcomes.
