abstract = "Residual efficacy of the insecticide deltamethrin, an EC formulation containing 25 g/L
AI + 225 g/L PBO (piperonyl butoxide synergist), against lab populations of Sitophilus oryzae,
Rhyzopertha dominica, Tribolium castaneum and Sitotroga cerealella was investigated in the
laboratory by applying product water solutions (0.25 mg AI/kg) to wheat grain (at 25±1°C and
60±5% r.h.). Adult mortality on 0, 7, 14 and 30 days old deposits was estimated after 2, 7 and 14
days of exposure to treated wheat grain and additional 7 days of recovery. Progeny reduction
(PR, %) was also assessed. After 2 days of exposure to deposits of all ages, deltamethrin caused
only 0-10% mortality of coleopterans (up to 37% after the recovery period) and 23-30% of S.
cerealella, while mortality before and after recovery from 14 days of exposure was 95-50% for
S. oryzae, 97-100% for R. dominica, 99-100% for T. castaneum and 100% for S. cerealella. Progeny
production of S. oryzae was highest after parents contacted with 14 days old deposit of
deltamethrin (PR, 76%), and lowest after contact with fresh deposit (PR, 95%), while R. dominica
and T. castaneum had no progeny on any deltamethrin deposit age in wheat (PR, 100%), and
S. cerealella had only a very low progeny (PR, 99%). The results showed that the synergised
deltamethrin, applied at 0.25 mg/kg in wheat grain, is a highly effective insecticide for storedproduct
insect control, while a higher dose is required for successful residual control of S. oryzae.",
