Cockroaches have been regarded as possible vectors of human enteropathogens. Their presence and crawl particularly in food handling establishments could be risky for human health. Therefore, this study was done to determine the vector potential of cockroach for medically important bacterial pathogens in restaurants and cafeterias. A cross-sectional study was conducted on cockroaches from restau...

Results A total of 439 skin tests were performed for indoor aeroallergens in pediatric patients. There were 57.6% (n = 253) men and 42.4% (n = 186) women with mean age of 6.3 years. Patients were divided into the following age-groups: children under 3 years (17.8%, n = 78), 3 to 5 years (35%, n = 154), 6 to 12 years (36%, n = 158) and 13 to 16 years (11.2%, n = 49).

INTRODUCTION Asthma affects approximately 10% of the world's population. Sensitization to allergens is an important risk factor, and exposure to allergens is associated with disease severity. METHODS We performed skin tests to evaluate allergen sensitization to mites, cockroaches, cats, dogs, and molds in 73 asthmatic patients. Enzyme Linked Immunosorbent Assay was used to assay the mite and ...

Insecticidal activity of NK-17 was evaluated both in laboratory and in field. It was found that the toxicity of NK-17 against S. exigua was 1.93 times and 2.69 times those of hexaflumuron and chlorfluazuron respectively, and the toxicity of NK-17 against P. xylostella was 1.36 times and 1.90 times those of hexaflumuron and chlorfluazuron respectively, and the toxicity of NK-17 against M. separa...

Worker yellowjackets (Hymenoptera: Vespidae) were captured in traps baited with combinations of an aqueous solution of acetic acid and polyethylene caps loaded with either butyl butyrate, heptyl butyrate, or isobutanol. Vespula germanica (F.) were captured in large numbers in traps baited with acetic acid and isobutanol or acetic acid and butyl butyrate. Vespula pensylvanica (Saussure) were cap...

Vespula germanica (F.) (Hymenoptera: Vespidae) is a highly invasive social wasp that exhibits a rich behavioral repertoire in which learning and memory play a fundamental role in foraging. The learning abilities of these wasps were analyzed while relocating a food source and whether V. germanica foragers are capable of discriminating between different orientation patterns and generalizing their...
