Delphastus Pusillus for Whitefly Control
Delphastus Pusillus for Whitefly Control
Delphastus pusillus is a small black beetle used to control whiteflies. It preys on all whitefly species and stages, but prefers eggs and nymphs, delivering high prey consumption, long adult survival, and rapid reproduction. This biological control agent is effective in tropical and semi-tropical plants and in commercial greenhouses where whiteflies are present.
For best results, store at 50-59 °F (10-15 °C) and release in the early morning or late evening. Open the container and gently shake beetles onto foliage near infestations, then place the container upright among plants to release the remaining beetles. It is most effective at high whitefly densities and may provide limited benefit when populations are low, since adult females must feed on over 200 eggs per day to reproduce. It avoids feeding on whitefly nymphs parasitized by Encarsia formosa and Eretmocerus eremicus, making it compatible with these parasites.

Plant was well packed and shipment was very fast. Received a very nice fully rooted plant in the pot!

Product was delivered promptly and the quality of the product was very good, as hoped for. I was thrilled to receive the product so quickly! Thank you!
Product is great. Didn't care for having to pay am extra $17 tariff to UPS to get it delivered, but I guess that's not your doing. Thank you Mr. President.
My new babay arrived safely and only lost two little leaves so far. The first one I ordered from different shop arrived with two leaves attached that fell off within ten minutes of unboxing and 22 leaves that had came off during shipping. So glad she arrived looking as beautiful as i was hoping. Also had a surprise red arrow syngonium cutting that’s beautiful. Also customer service was amazing. Will definitely order from them again. Hoghly recommend this shop.
Great flag and it works well on our hangar ceiling. A little worried it wouldn't arrive in time for our event but it did.
Enjoyed putting them together
I think I’m in love! This beauty came delicately packaged. Seemed to have no stress at all from shipping. I live in Miami, I was worried about shipping all the way from California. To my surprise she arrived well taken care of already. I can tell this grower takes pride in caring for these babies. Shipping was fast. I just ordered again same day!
