Product Overview

The Koppert Delphibug Predatory Beetles (432) contains 1,000 adult Delphastus catalinae or predator beetles in buckwheat hulls. They contest all phases (eggs and larvae) of greenhouse whiteflies (Trialeurodes vaporariorum) and cotton whiteflies (Bemisia tabaci). They eliminate large number of target species by actively biting and sucking them until dried. Once an egg, larvae or pupa has been sucked, only the outer casing will stay. The conventional yellow excrement is a good indication of feeding activity.

For application, rotate or shake the bottle gently before use. Introduce in a DIBOX or on the leaf (gerbera). Administer in a cluster and discharge in the morning or in the evening.

Comments

The predatory beetles need sufficient food (whitefly eggs) in order to reproduce.
The beetles can play dead by pulling in their legs and head.
Activity can be confirmed by the presence of yellow excrement on the underside of the leaf.
