Trichogramma achaeae is a parasitic wasp, used in the control of butterflies and tuta absoluta. Trichogramma achaeae lays its eggs in the eggs of a butterfly or moth. After a butterfly egg has been parasitized, it turns black. An adult Trichogramma achaeae is about 0.3 mm in size. Their kinked antennae and dark brown abdomen are remarkable.
Life cyle and relative effectiveness
Adults lay eggs ín the eggs of butterflies and tuta absoluta. Eggs that are heavily hairy or have scales are less suitable for parasitation. The amount of parasitic wasps that develop in the egg can go up to 20 to 30 pieces. The proces from egg to adult will take approximately 9 to 11 days. The total life cycle of trichogramma is 12 to 16 days. The optimum temperature is between 20 and 25°C.
Application and dose
Trichogramma achaeae must be stake out at first observation. We recommend a combination with pheromones.
Preventive 10 to 15 parasitic wasps per square meter.
Curative 25 to 150 parasitic wasps per square meter.
