Delphastus catalinae is a specialized whitefly predator in the lady beetle family. The adult beetles fly, while larvae are slow moving and travel from plant to plant on leaves. Delphastus is used to control whiteflies in tropical and semi-tropical plantings as well as commercial greenhouses.Delphastus avoids feeding on parasitized whiteflies, therefore is compatible with the use of Encarsia spp. (see Encarsia) and Eretmocerus spp. whitefly parasites. Delphastus also tends to feed in high-density whitefly populations, while parasites do best at lower densities of whiteflies. Delphastus adults prefer feeding on whitefly eggs. Delphastus do not survive in the absence of prey, therefore should be released only after whiteflies are detected.
- Roughly .5-1.0 predator per 1 sf.
- Once the beetles warm up they become active immediately, therefore should be released as soon as possible. If necessary, beetles can be stored for 1-2 days at 50-61º F (10-16º C), but longer storage will reduce egg laying.
