Abstract:
Polyethylene film controlled release packets utilizing ethylene dibromide (EDB) and pdichlorobenzene
(PDB) were designed and tested against late instar larvae of Galleria mellonella
(L.). EDB controlled release packets gave 100% control of larvae in 48 h under
experimental conditions at 26.6° and 32.3°C. PDB controlled release packets gave 13.3 and
17.2% control of larvae in 96 h under similar temperature regimes.
Permeation constants for the EDB and PDB controlled release systems were derived from
experimental rates observed in 4 and 6 mil polyethylene dispenser packets at temperatures of
l0.0°-35.0°C.
