Spider Mite Resistance

Spider mite resistance refers to genetic traits that confer tolerance or resilience to spider mite infestations, a common horticultural pest affecting cannabis cultivation. This resistance is not a single gene but rather a combination of plant characteristics—including leaf texture, epicuticular wax profiles, and pest-deterrent secondary metabolites—that reduce mite colonization or reproduction rates. Breeders working in this category often select parent plants showing reduced damage under mite pressure or recovered vigor post-infestation. Spider mite resistance is particularly relevant in indoor and outdoor cultivation programs where integrated pest management is a priority. Documentation of resistance traits remains informal across most breeding communities, though some cultivators maintain detailed phenotype records.

Breeders incorporate spider mite-resistant genetics by selecting for parents that show reduced feeding damage, slower mite population growth, or faster recovery after exposure. This trait is often stacked with other pest-resistance or resilience characteristics to improve overall cultivation robustness without chemical intervention.
