GrowersHouse Duponchelia Fovealis Lure 2 Pack

Delphastus pusillus is a small black beetle that preys on whiteflies and whitefly eggs, providing a biological control option for whiteflies in tropical and semi-tropical plants and commercial greenhouses. It preys on all whitefly species and life stages but prefers eggs and nymphs, with high prey consumption rates, long adult survival, and high reproduction. The predator avoids feeding on whitefly nymphs parasitized by Encarsia formosa and Eretmocerus eremicus in later development stages, making it compatible with these whitefly parasites. Adult female beetles must feed on over 200 eggs per day to reproduce, which may limit benefits in greenhouses where whitefly populations are low. Item numbers DPUS1 and DPUS1K are available.

Storage and release: store at 50-59 °F (10-15 °C) before use, release in the early morning or late evening, open the container and gently shake beetles onto foliage close to infestations, then place the container upright among plants to release the remaining beetles. Application rate guidelines for the Duponchelia fovealis lure by infestation level: Preventative — 1–2 beetles per square foot or at least 100 adults per whitefly hotspot, or 10 adults per infested plant, weekly for 3–4 weeks; Moderate — 2–4 beetles per square foot or 500 adults per hotspot, or 1–2 adults per 10 square feet, weekly for 4 weeks; Heavy — 4–6 beetles per square foot or 500 adults per hotspot, or 3–4 adults per 10 square feet, weekly until established. Delphastus pusillus is most effective at high whitefly densities.
