• storage after receipt: 1-2 days
• storage temperature: 8-10°C/47-50°F

Remarks

Eretmocerus eremicus is less susceptible to pesticides than Encarsia formosa.

Intensive deleafing (in tomatoes) hinders the population build up of whitefly parasites.

 

Appearance

Eretmocerus eremicus

Female adults: lemon-yellow

Male adults: brownish-yellow, thick antennae

Other stages: develop inside host

 

Encarsia formosa

Female adults: black head, black thorax, yellow abdomen

Male adults: hardly appear

Other stages: develop inside host

 

Mode of action

Female adult parasitic wasp parasitizes the larva of the whitefly. Host feeding also takes place.

 

Visual effect

After about 2 weeks, the first parasitized pupae can be seen in the crop. The parasitized whitefly pupa turns yellow or black in colour dependent of the combination parasite/host. The adult parasitic wasp emerges from the pupa through a round hole.
