BACKGROUND The aim was to determine the incidence of seed migration not only to the chest, but also to the abdomen and pelvis after transperineal interstitial prostate brachytherapy with loose (125)I seeds. METHODS We reviewed the records of 267 patients who underwent prostate brachytherapy with loose (125)I seeds. After seed implantation, orthogonal chest radiographs, an abdominal radiograph...

18 Netting window screens and eave baffles (WSEBs), allowing mosquitoes to enter but not exit 19 from houses, were assessed as an alternative to indoor residual spraying (IRS) for malaria vector 20 control. WSEBs treated with water, the pyrethroid lambda-cyhalothrin (LC), or the 21 organophosphate pirimiphos-methyl (PM), with and without a binding agent (BA) for increasing 22 insecticide persis...

Indirect effects of insect control strategies on weed populations are important to consider when developing robust integrated pest management strategies. Weed seed predation rates were investigated in corn managed under three contrasting treatments based on control practices for corn rootworm: (1) the transgenic crop Cry3Bb Bt corn, (2) the broad-spectrum insecticide tefluthrin, and (3) no inse...

BACKGROUND Developing scientifically valid, economically acceptable insecticide resistance management (IRM) programs is critical for sustainable insect management. The diamondback moth, Plutella xylostella (L.), has demonstrated an ability to develop resistance to many different classes of insecticides, including proteins produced by the bacterium Bacillus thuringiensis Berliner (Bt). Recently ...

Seeds of Balanites aegyptiaca stored for one year were germinated using cold and boiling water pre-treatments and different sowing orientations. Whole fruits were soaked in cold water for (18, 24 and 48 hours, respectively), while extracted sun dried seeds were immersed in boiling water for 7 minutes. Seeds of each treatment were sown in three orientations (seeds laid vertically with stalk end ...

Insecticide sprays and dusts are used for controlling bed bugs, Cimex lectularius L. In natural environments, bed bugs have daily access to hosts after they are exposed to insecticides. The established laboratory insecticide bioassay protocols do not provide feeding after insecticide treatments, which can result in inflated mortality compared with what would be encountered in the field. We eval...

Pesticides widely used in the agricultural market led to an increase quality and yield of crops. However, pesticides are a major concern environment as they also harm non-target creatures, because pesticide resistance, mutagenic carcinogenic effects. In this study, we aimed research potential mutagenicity Karate Zeon which is synthetic pyrethroid insecticide. Salmonella typhimurium assay (Ames ...

malaria has recently been resurged in some parts of iran which is bordered with armenia, naxcivan and turkey. an attempt was made to asses the current status of insecticide resistance in the main malaria vector , an.sacharovi. adult engorged mosquitoes were collected from dwellings during the seasonal activity of the vector, which is synchronized in summer 2001. mosquitoes were subjected to the...

BACKGROUND Obligate bacterial symbionts alter the diets of host animals in numerous ways, but the ecological roles of facultative bacterial residents that colonize insect guts remain unclear. Carabid beetles are a common group of beneficial insects appreciated for their ability to consume insect prey and seeds, but the contributions of microbes to diet diversification in this and similar groups...
