Pest Pressure Terpenes

Pest pressure terpenes refer to volatile compounds that plants produce in response to herbivory or pest stress. Cannabis breeders have observed that certain chemotypes exhibit elevated levels of defensive monoterpenes and sesquiterpenes when exposed to insect feeding or mite populations. Lineage records frequently report that some cultivars display naturally higher baseline terpene production, potentially linked to pest-resistance traits selected across generations. These stress-response profiles are of interest to breeding programs focused on integrated pest management (IPM) and cultivar resilience. Understanding which genetic backgrounds express robust terpene defenses can inform selection strategies for greenhouse and outdoor production environments.

Breeders working in resilience-focused programs monitor terpene profiles under controlled pest exposure to identify parents with reliable defensive chemistry. Selection for elevated pest-pressure terpenes may support cultivation goals in low-input or organic production systems.
