چکیده

Concerns about traditional chemical pesticides has led to increasing research into novel mosquito control methods. This study compared the effectiveness of 2 different types of polystyrene beads for control of mosquito larvae in south-east Islamic Republic of Iran. Simulated field trials were done in artificial pools and field trials were carried out in 2 villages in an indigenous malaria area using WHO-recommended methods. Application of expanded polystyrene beads or shredded, waste polystyrene chips to pool surfaces produced a significant difference between pre-treatment and post-treatment density of mosquitoes (86% and 78% reduction respectively 2 weeks after treatment). There was no significant difference between the efficacy of the 2 types of material. The use of polystyrene beads as a component of integrated vector management with other supportive measures could assist in the control of mosquito-borne diseases in the Islamic Republic of Iran and neighbouring countries. 1School of Public Health and Institute of Health Research; 2Centre for Environmental Research; 3Digestive Diseases Research Centre, Tehran University of Medical Sciences, Tehran, Islamic Republic of Iran (Correspondence to H.

La présente étude a comparé l'efficacité de deux types de billes de polystyrène dans la lutte contre les larves de moustiques dans le sud-est de la République islamique d'Iran. Les études de simulation du terrain ont été réalisées dans des bassins artificiels alors que les essais sur le terrain ont été conduits dans deux villages d'une zone où le paludisme est autochtone, avec des méthodes recommandées par l'Organisation mondiale de la Santé. L'application de billes de polystyrène expansé ou de copeaux de polystyrène recyclé sur la surface des bassins a entraîné une différence significative entre la densité des moustiques avant et après le traitement (86 % et 78 % de réduction respectivement après deux semaines de traitement). Il n’y avait pas de différence significative entre l'efficacité des deux types de matériaux. L'utilisation de billes de polystyrène en tant que composante de la gestion intégrée des vecteurs avec d'autres mesures d'appui pourrait contribuer à lutter contre les maladies transmises par des moustiques en République islamique d'Iran et dans les pays voisins. 06 Field efficacy of expanded polystyrene fc.indd 1042 10/9/2012 1:03:14 PM طسوتلما قشرل ةيحصلا ةلجلما شرع نماثلا دلجلما شراعلا ددعلا

Expanded polystyrene (EPS) floats for surveillance of Ochlerotatus japonicus.

Blocks of expanded polystyrene (EPS) were placed in a variety of habitats to investigate their potential as an egg-collection device for container-dwelling Aedes and Ochlerotatus species. Eggs from Ochlerotatus japonicus, Oc. triseriatus, Oc. hendersoni, and Aedes albopictus were collected with EPS floats. The float provides an inexpensive, low-maintenance alternative to the Centers for Disease...

Potential use of scrap expanded polystyrene beads for the control of Aedes triseriatus.

The potential use of expanded polystyrene (EPS) beads for control of Aedes triseriatus was tested in the laboratory and the field. Laboratory studies showed that beads present in amounts which persisted throughout a season significantly reduced the emergence of Ae. triseriatus adults by preventing normal eclosion from the pupae. In the field, tree holes containing EPS beads had significantly fe...
