How does Delphibug work
The predatory beetles need sufficient food (whitefly eggs) in order to reproduce. The beetles can play dead by retracting their legs and head. Activity can be confirmed by the presence of yellow excrement on the underside of the leaf Adults and larvae eat large numbers of whitefly eggs and larvae. They bite them open and consume them.

Best working conditions Delphibug
The minimum temperature for successful use of Delphibug is 20°C. However, Delphibug is at its most effective at temperatures between 22°C and 30°C.
Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Failure to do so can have a negative impact on their quality. In case you do need to store Delphibug, please follow the instructions below.
  • After receipt: 1-2 days
  • Storage temperature: 12-14°C
  • In the dark
  • keep the bottle horizontal
