Pesticides Registered for Mosquito Control in South Dakota

Pesticides alone will not eliminate all mosquitoes. The use of pesticides to control mosquitoes around the home and yard must be part of a multifaceted approach that includes the following non-chemical tactics: • Eliminate standing water. • Fix broken window screens. • Use outdoor bug lights. • Installing carbon dioxide-baited traps. Some mosquitoes will always “get through.” If you will be outdoors, it is recommended that you wear a mosquito repellent of your choice, avoid being outdoors around sunset and sunrise, and cover as much skin as possible with appropriate clothing. For more information on selection and use of insect repellents, refer to FS 920 Personal Mosquito Repellents available at your local Extension office or online at http://sdces.sdstate.edu/westnile/publications.htm. This publication lists the most common insecticides that are registered in South Dakota for use around the house and yard. The products are arranged by the active ingredient. The active ingredient is usually listed prominently in the first section of the label. This section will list the chemical name and/or the common name of the pesticide and also the concentration. This list was current as of June 2004, but label uses and registrations change. Before using any pesticide, be sure to read the entire label to ensure that the product can be used for mosquitoes, can be applied around the home and yard, and to be sure all safety restrictions are followed. For more information, refer to FS 923 Controlling Mosquitoes Around the Home and Yard

Personal Mosquito Repellents Available in South Dakota — 2004

The most commonly available insect repellents contain either DEET or permethrin. This publication provides information on specific repellents that are registered for sale in South Dakota in Spring 2004. Personal mosquito repellents are products that can be applied directly onto the human skin or clothing for the purpose of repelling or killing adult mosquitoes. While repellents containing the chemical DEET can be applied directly on human skin and clothing, products containing the insecticide permethrin cannot. Permethrin must be applied only on clothing or related apparels such as hats,shoes, and overalls several hours before being worn. Organic alternatives to DEET or permethrin are also available for chemically-sensitive individuals. There appears to be a limit in the duration of protection time that increasing DEET concentrations may provide. For example, a product containing 100% DEET may provide no more than 10 hours of protection from mosquito bites. The duration of protection time provided by products containing 35% and 100% DEET may not be significantly differen

The Release of Insects Sterilized by Colbalt 60 to Control a Wild Population of Stable Flies at the SDSU Beef Cattle and Sheep Nutrition Unit in Brookings

Sterile stable flies were released weekly a t the SDSU Beef Cattle and Sheep Nutrition Unit at Brookings from July 24 through September during the summer 1986 season t o eliminate wild populations of insects. Flies that were sterilized were marked with a dye so when recaptured by an insect net or a sticky trap they could be differentiated from wild, normal or fertile flies. A trend toward reduced f l y numbers was observed 3 weeks following the first release. A 1:5 ratio of sterile to wild flies was achieved in 6 weeks

Best Management Practices for Corn Production in South Dakota: Corn Insect Pests

Historically, the major corn insect pests have been corn rootworms (northern and western), European corn borer, and black cutworm. Bt-corn hybrids are effective against most of these pests. However, Bt-corn hybrids are not effective against corn leaf aphid, corn root aphid, sap beetles, corn rootworm adults, grasshoppers, white grubs, wireworms, seed corn beetle, and seed corn maggots. These insect pests can reduce corn yields. This chapter discusses the management and biology of important corn insect pests commonly observed in South Dakota

The dominant Anopheles vectors of human malaria in the Asia-Pacific region: occurrence data, distribution maps and bionomic précis

<p>Abstract</p> <p>Background</p> <p>The final article in a series of three publications examining the global distribution of 41 dominant vector species (DVS) of malaria is presented here. The first publication examined the DVS from the Americas, with the second covering those species present in Africa, Europe and the Middle East. Here we discuss the 19 DVS of the Asian-Pacific region. This region experiences a high diversity of vector species, many occurring sympatrically, which, combined with the occurrence of a high number of species complexes and suspected species complexes, and behavioural plasticity of many of these major vectors, adds a level of entomological complexity not comparable elsewhere globally. To try and untangle the intricacy of the vectors of this region and to increase the effectiveness of vector control interventions, an understanding of the contemporary distribution of each species, combined with a synthesis of the current knowledge of their behaviour and ecology is needed.</p> <p>Results</p> <p>Expert opinion (EO) range maps, created with the most up-to-date expert knowledge of each DVS distribution, were combined with a contemporary database of occurrence data and a suite of open access, environmental and climatic variables. Using the Boosted Regression Tree (BRT) modelling method, distribution maps of each DVS were produced. The occurrence data were abstracted from the formal, published literature, plus other relevant sources, resulting in the collation of DVS occurrence at 10116 locations across 31 countries, of which 8853 were successfully geo-referenced and 7430 were resolved to spatial areas that could be included in the BRT model. A detailed summary of the information on the bionomics of each species and species complex is also presented.</p> <p>Conclusions</p> <p>This article concludes a project aimed to establish the contemporary global distribution of the DVS of malaria. The three articles produced are intended as a detailed reference for scientists continuing research into the aspects of taxonomy, biology and ecology relevant to species-specific vector control. This research is particularly relevant to help unravel the complicated taxonomic status, ecology and epidemiology of the vectors of the Asia-Pacific region. All the occurrence data, predictive maps and EO-shape files generated during the production of these publications will be made available in the public domain. We hope that this will encourage data sharing to improve future iterations of the distribution maps.</p
