Title: Cockroaches as House Hold Pests
Author: Mashaer Mohi El din, Mohammed
Abstract: A laboratory study was carried out to investigate the hygienic importance of three cockroach species in the Sudan (Blattela germanica, Blatta orientalis and Periplaneta americana) as mechanical transmitters of pathogenic bacteria. This was followed by controled experiments using insecticides (propoxur and malathion), chemical compounds (sodium fluoride and boric acid) and natural plant products (usher leaves and whole fruits) with the aim of finding effective, environmentally safe methods of control. Standard bacteriological methods were used to isolate and identify pathogenic bacteria carried by cockroaches. Baits composed of sugar and starch containing insecticidal components was employed in the experiments. Palatability and mortality values were statistically analyzed and expressed as LD50 and LD95 (the concentration of the test that killed 50% and 95% of the exposed adults after 24 hours, respectively). The study showed that cockroaches transmit several pathogenic bacteria. Although insecticides were more toxic than chemical compounds and the latters were more toxic than natural plant products, the study recommends the use of natural plant products for control because of environmental, economical and practical reasons
