Wirkung der Glasur von Reis auf die Vermehrungsfähigkeit von Vorratsschädlingen

The glazing of rice kernels with a coating of glucose and talc has a limited effect against infestation by some stored product insects. In the case of long kernel rice the development of te offspring ofTribolium castaneum, Tribolium confusum, Sitotroga cereallella andOryzaephilus surinamensis is significantly inhibited. In case of round kernel rice, a protecting effect againstTribolium castaneum, Tribolium confusum andOryzaephilus surinamensis is observable; whereasSitophilus granarius, Sitophilus oryzae andRhizopertha dominica have a greater number of progeny on glazed than on unglazed round kernel rice.
