Specifications

Active Ingredients 15,000 Eretmocerus pupae on 250 cards Each cardboard strip contains 5 cards each, wrapped in plastic, in a cardboard box, each card holds 60 parasitized whitefly pupae.
Tech Comments Ercal is best to be used in combination with generalist predatory mites (Amblyseius andersoni, Amblyseius swirskii, Neoseiulus cucumeris or Amblydromalus limonicus) or, in tomato, with predatory mirid bugs (Macrolophus pygmaeus). On heated, edible and ornamental crops (+16°C) Eretmocerus can be used throughout the year. On other crops use late spring to late autumn; ideal for poinsettia crops.
Control Mode of action: Adult female parasitic wasps parasitize the second and third larval stage of the whitefly. Additionally, host feeding also occurs. Due to Eretmocerus laying its egg under or next to the whitefly scale, gives this species a broader host range compared to Encarsia. Visual effect: Parasitized whitefly pupae turn yellow, the adult parasitic wasp can be seen clearly within the parasitized whitefly pupae shortly before it emerges. Environmental conditions: For optimal performance of Eretmocerus eremicus the 24 hour average greenhouse temperature needs to be at least 20°C/68°F. Eretmocerus eremicus is still active at temperatures above 30°C/86°F.
