The present article discusses three cases of human infestation by Corythuca ciliata (Lace bugs), a parasite of plane trees. The cases were all in the Piedmont region of northwest Italy and the symptoms involved a large number of hives on the subjects' bodies which were scarcely or not at all itchy and which spontaneously cleared up in all the cases in less than 24 hours. It can be concluded tha...

J. Econ. Entomol. 86(3): 712-714 (1993) ABSTRACT We tested a population dynamics model that predicts that swarming of honey bees, Apis mellifera L., is a regulatory process of tracheal mites, Acarapis woodi (Rennie), parasitism. If the model is correct, then feral colonies that are free to swarm should have fewer numbers of infested worker bees, infested workers should have fewer numbers of mit...

Ethiopia’s largest freshwater lake, Lake Tana, is home to 21 endemic fish species, the majority of which are cyprinids in genus Labeobarbus. The lake undergoing numerous ecological changes, including an invasion water hyacinth (Eichhornia crassipes (Mart.) Solms (WH). aim this study was predict future productivity Tana by considering increasing infestation. This accomplished analyzing a 12-year...

The cost and effectiveness of two bed bug (Cimex lectularius L.) integrated pest management (IPM) programs were evaluated for 10 wk. Sixteen bed bug-infested apartments were chosen from a high-rise low-income apartment building. The apartments were randomly divided into two treatment groups: diatomaceous earth dust-based IPM (D-IPM) and chlorfenapyr spray-based IPM (S-IPM). The initial median (...

Current bed bug, Cimex lectularius L., control usually involves insecticide applications that pose a high risk of insecticide exposure to residents and applicators. To minimize these risks and the amount of insecticides used, we designed and evaluated a dust band treatment technique. The laboratory assay showed that 1% cyßuthrin dust treated bands are highly effective in killing bed bugs. We fu...

Two passive methods in the assessment of intradomiciliary infestation by Rhodnius ecuadoriensis were tested: (i) the Gomes Nu ez sensor box (GN), (ii) sheets of white typing paper and (iii) one active timed manual method. The study was carried out in the Alto Chicama River Valley, Province of Gran Chim , Department of La Libertad. The study design consisted of an initial searching of triatomine...
