Spider Mite Resistance

Spider mite resistance refers to a plant's genetic capacity to withstand or tolerate infestations by spider mites (Tetranychus species), common agricultural pests that damage cannabis through feeding on leaf tissue. Breeders have identified and selected for traits that reduce pest susceptibility, including leaf surface characteristics, trichome density, and plant vigor that may help mitigate damage. This classification encompasses genetics sourced from diverse lineages known to exhibit stronger tolerance to spider mite pressure under cultivation. Spider mite resistance is of particular interest in breeding programs targeting sustainable, low-input production environments. While not absolute immunity, resistance traits can reduce the severity of infestations and diminish the need for intensive pest management interventions.

Breeders incorporate spider mite resistance into commercial and craft breeding lines to reduce crop losses and chemical input requirements. Crosses between resistant cultivars and desirable phenotypes have produced offspring with improved pest tolerance while maintaining target cannabinoid and terpene profiles.
