background: hymenolepis diminuta is a cestod of rodents and rarely infects humans. infection in humans is via ingestion of infected insects. this study was aimed to detect h. diminuta cysticercoids in red flour beetles, tribolium castaneum, and cockroaches originated from different regions of iran. methods: the red flour beetles and cockroaches were collected from local bakeries in five cities ...

conclusions the results showed that p. americana is a possible reservoir and potential vector of some pathogenic agents. results one hundred percent of cockroaches had bacterial infections. culturing of the external parts wash homogenates resulted in the isolation of escherichia coli, proteus, serratia, klebsiella, enterobacter, pseudomonas, staphylococcus aureus, streptococcus, enterococcus, c...

The Internet has brought great convenience to society, but copyright disputes have become more complex in the era, and new features about by led changes litigation. Taking photographic works as an example, article briefly analyses characteristics of era introduces “copyright cockroaches” (plaintiffs who seek gain benefits filing numerous lawsuits). Through analysis overseas current situation li...

cockroaches is not easy to document, given the precarious hygienic conditions of some of the habitats where they live. In fact, asthma is the only disease consistently associated with exposure to cockroaches [4–6] . Curiously enough, cockroaches have no lungs (they breathe through lateral spiracles in the body) [1] , but inhalation of cockroach materials by humans may trigger IgE antibody respo...

In response to the anthropogenic assault of toxic baits, populations of the German cockroach have rapidly evolved an adaptive behavioral aversion to glucose (a phagostimulant component of baits). We hypothesized that changes in the peripheral gustatory system are responsible for glucose aversion. In both wild-type and glucose-averse (GA) cockroaches, D-fructose and D-glucose stimulated sugar-gu...

Static electric fields are found throughout the environment and there is growing interest in how electric fields influence insect behaviour. Here we have analysed the locomotory behaviour of cockroaches (Periplaneta americana) in response to static electric fields at levels equal to and above those found in the natural environment. Walking behaviour (including velocity, distance moved, turn ang...
