Honey bee (Apis mellifera) colonies of African and European descent were compared for levels of Varroa destructor infestation in 3 different ecological regions in Mexico. The 300 colonies that were studied were located in subtropical, temperate sub-humid, and temperate dry climates. The morphotype and mitotype of adult bees as well as their rates of infestation by varroa mites were determined. ...

Aim: To study the prevalence of tick infestation in dogs in and around Bhubaneswar. Materials and Methods: A total of 610 dogs (360 stray dogs & 250 pet dogs) in and around Bhubaneswar belonging to either sex were examined for tick infestation during a period of one year (Aug 2011July 2012). Standard parasitological procedures were followed for collection, processing and identification of ticks...

Insect infestation behaves as a complex system, characterized by non-linear spatial dynamics and emergent patterns that evolve from smaller to larger spatial scales. The emerald ash borer (EAB) is an invasive species that has infested and killed millions of ash trees across North America. Existing EAB models use traditional statistical approaches that often cannot address the spatiotemporal com...

Birds face varying risk from parasites as they select and utilize habitat. Unfortunately, behavioral and habitat correlates of parasitism in birds are not well documented. This study combines data from a foraging behavior study with results from a banding study to test whether behavior and habitat affect an ectoparasite infestation by trombiculid mite (chigger) larvae on the bird community foun...

Short-term oxygen consumption and filtration rate experiments were conducted to evaluate the response of edible cockle Cerastoderma edule when infested by the Digenean trematod Labratrema minimus. In this experiment the metabolic activities of bivalves were measured to detennine this particular aspect of the host-parasite interaction. We have used the Bucephalidae digenea Labratrema minimus inf...

Goat warble-fly infestation is caused by przhevalskiana silenus (Diptra Oestridae) larvae and it is characterized by the presence of warble under the hide of the back and flanks of the animal. This study was carried out from March 2009 to March 2010 on the hides sent to the khorasn leather industries for grading, processing and tanning. This study demonstrated from 340,797 goat hides e...

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...
