The impacts of infestation by the green peach aphid (Myzus persicae) on sweetpotato whitefly (Bemisia tabaci) settling on tomato were determined in seven separate experiments with whole plants and with detached leaves through manipulation of four factors: durations of aphid infestation, density of aphids, intervals between aphid removal after different durations of infestation and the time of w...

INTRODUCTION Jigger infestation is an important but neglected public health problem. The study assessed the knowledge, attitude and practices of household members on jigger infestation, practices and control within Murang'a district, a rural location in Kenya. METHODS A cross-sectional descriptive study design was used. Structured interview schedules and observation checklist were used to col...

Received: December 2011, Accepted: September 2012 Background: Head lice infestation is one of the most common parasitic infections with a long history in the world. The purpose of this study was to determine the prevalence of head lice infestation among 3-6 years old children going to nursery schools in Kashan, Iran in 2009. Materials and Methods: This cross-sectional study was performed on 120...

Few studies have examined how insect outbreaks affect landscape-level hydrologic processes. We report the hydrologic effects of the invasive, exotic hemlock woolly adelgid (HWA) in a headwater catchment in the southern Appalachian Mountains. The study watershed experienced complete mortality of an evergreen tree species, Tsuga canadensis (L.) Carr. (eastern hemlock), after infestation was first...

Objective: To assess the health needs for health promoting Ashram schools in rural Wardha. Methods: It was a cross sectional study undertaken in 10 Ashram schools, using qualitative (SWOT analysis, Transect walks and Semi-structured interviews of teachers) and quantitative (Survey) methods. Hemoglobin examination of all children was done by using WHO hemoglobin color scale. Anthropometric measu...

Invasive, polyphagous crop pests subsist on a number of crop and non-crop resources. While knowing the full range of host species is important, a seasonal investigation into the use of non-crop plants adjacent to cropping systems provide key insights into some of the factors determining local population dynamics. This study investigated the infestation of non-crop plants by the invasive Drosoph...

This is a report of a case of bird mite infestation which occurred in Wollongong in mid-December1996.The individual suffered hundreds of bites, most of which were marked by itchy red papules3–4 mm in diameter. Tiny mobile parasites (< 1 mm) collected from the skin and adjacentbedroom wall were identified as bird mites from the family Gamasidae, most probably from thegenus Ornith...

Histamine is used in bronchial and dermal provocation, but it is rarely considered an environmental risk factor in allergic disease. Because bed bugs defecate large amounts of histamine as a component of their aggregation pheromone, we sought to determine if histamine accumulates in household dust in bed bug infested homes, and the effects of bed bug eradication with spatial heat on histamine l...

Dermanyssus gallinae (Mesostigmata: Dermanyssidae), a mite of poultry, represents the most important ecotoparasite of egg-laying poultry in several countries. We estimated the prevalence of D. gallinae infestation in 38 industrial poultry farms (28 egg-laying and 10 reproductive hen farms) in the governorate of Nabeul (North-East Tunisia). Traps were placed in two locations of each farm during ...
