Glasshouse vs Outdoor — Pest Behaviour Differences

Environmental buffering changes outbreak dynamics.

Glasshouse Systems

Characteristics: - Higher temperature stability - RH manipulation possible - Predator programmes structured - Localised microclimates

Effects:

Thrips: - Flower-driven risk amplified - Heat spikes cause rapid escalation

Spider Mite: - Low RH structural outbreaks common - Ventilation critical

Aphids: - Flush cycles amplified by fertigation - Parasitoid stability key

Characteristics: - Natural RH variation - Rainfall impact - Wind dispersal

Effects:

Thrips: - Less humidity-driven - More migration-based

Spider Mite: - Often moderated by natural humidity - Localised drought stress increases risk

Aphids: - Strong migration influence - Natural enemies more diverse

Protected systems amplify environmental instability. Outdoor systems amplify migration instability.
