TNLA Green Report Podcast, Season 5, Episode 4: Thrips Management & Biological Control Innovations, Katerina Velasco-Graham & Team

Implement strict sanitation protocols in greenhouses and nurseries, including removing and destroying infested plant parts, to prevent the establishment and spread of short spine thrips.

Utilize scouting methods like beating foliage over a white clipboard or setting up blue or white sticky traps to monitor for thrips, especially on young leaves and flowers.

Differentiate short spine thrips from other thrips species by their smaller size, rapid movement, two-toned body coloration (golden-brown head/thorax, dark abdomen), and specific antennae features (requires magnification).

Integrate biological control agents such as predatory mites (e.g., Amblyseius swirskii), nematodes, and minute pirate bugs (Orius spp.) into your pest management program, as these are commercially available and show promise.

Consider pre-planting dip treatments for cuttings using biopesticides (e.g., Baeria Bassiana) or mineral oils to eliminate initial infestations, as demonstrated by Florida studies.

When chemical control is necessary, use products effective for fast knockdown and residual toxicity; top conventional options include Chloronapir, Spinosad, and Sufoxaflor plus Spinetoram, while mineral and sesame oils are effective biorational choices.

Maintain vigilance with incoming plant shipments, especially from regions known to have short spine thrips (e.g., Florida), by implementing a quarantine period and thorough scouting before introducing new plants into your main growing areas.
