Control of relative humidity during shipment of parasitic insects

Control of relative humidity during shipment of parasitic insects

Journal of Economic Entomology 80(2): 537-539

Control of relative humidity was required for maximum survival during shipment of nine species [Meigenia mutabilis, Anastatus disparis, Glyptapanteles flavicoxis, Opius dimidiatus, Chrysocharis clarkae, Diglyphus begini, Edovum puttleri, pediobus foveolatus, and Tetrastichus asparagi] of adult parasitic insects. Combinations of humiditrons (container of saturated salt solutions covered with semipermeable surgical dressing), moist sponges, and freezepacks provided adequate relative humidity for 4 d, the normal time required for domestic shipment, but only the humiditrons were suitable for a longer time period of 11 d.
