The parasitic wasp duo against the whitefly combination

What is Eretmix-System?

• Combination of the black parasitic wasp Encarsia formosa and the lemon yellow wasp Eretmocerus eremicus
• Effective against the tobacco whitefly Bemisia tabaci and the greenhouse whitefly Trialeurodes vaporariorum 

What are the benefits of Eretmix-System?

• Can be used against mixed whitefly populations
• Both parasitic wasps kill whitefly larvae through host feeding
• E. formosa is efficient at low temperatures and prefers to parasitize the greenhouse whitefly
• E. eremicus is efficient at high temperatures and prefers to parasitize the tobacco whitefly 

How does biocontrol control with Eretmix-System work?

• The females prefer to prick the young larvae and then suck them (host feeding)
• Female parasitic wasps parasitize the larvae from the second to the fourth stage 

In which crops can you introduce Eretmix-System?

• Vegetable crops such as tomato and pepper
• Ornamental crops such as anthurium and poinsettia
