Voracious ladybird to tackle large whitefly hot spots

What is Delphastus-System?
  • The small black ladybird Delphastus pusillus
  • Both the larvae and the adults are efficient against whitefly
  • Biological control of both the tobacco whitefly Bemisia tabaci and the greenhouse whitefly Trialeurodes vaporariorum
  • Curative biological control agent of large whitefly hot spots 
What are the benefits of Delphastus-System?
  • Active during the entire season because D. pusillus is not diapause sensitive
  • Whitefly larvae that have already been parasitized by parasitic wasps will be avoided
  • Can survive a short cold period 
How does biological control with Delphastus-System work?
  • D. pusillus traces prey through touching
  • They prefer the early stages but feed on all whitefly stages
  • Females eat 100 to 150 whitefly eggs a day to ensure reproduction  
  • Both the larvae and the adults need a large food supply to survive, more than 1000 whitefly eggs or 700 larvae
  • They need to be introduced in large whitefly populations
