| Relation | Central Utah Project; Western Waters Digital Library; to a depth of over eight inches 20 cm and holding the depth over a complete growing season would prevent more than one brood of floodwater flood water mosquitoes aedes species from being produced the deeper water is less conducive to production of permanent water mosquitoes culex and culiseta Culi seta species than shallow water less than eight inches 20 cm in depth 8 A delay in flooding large saltgrass salt grass areas until the middle of september would eliminate the most serious mosquito producing problem along the wasatch front when these areas are flooded earlier in the year if they could be kept covered with water throughout the remainder of the mosquito breeding season only one brood of aedes mosquitoes would be produced that year large numbers of culex and culiseta Culi seta mosquitoes could be produced throughout the remainder of the breeding season in this habitat if water depths were eight inches or less 9 saltgrass Salt grass alone or mixed with other vegetative types is generally associated with the worst mosquito producing habitat in utah elimination or prevention of saltgrass salt grass either through water management or physical removal often results in significant reduction in mosquito production and allows growth of more desirable vegetation for wildlife use saltcedar Salt cedar is also associated with extreme mosquito production and difficult control control of saltcedar salt cedar is difficult but it is generally associated with fluctuating water levels and moist soil 10 maintenance of stable water levels during july through september concentrates the larvae and pupae of deer and horse flies along well defined shorelines the concentration of exposed pupae prior to emergence of adults results in increased predation losses to birds and other natural predators if a control program is started for these flies chemical spraying of shore line areas is one measure that will have to be considered its su success ccess access will depend upon concentrating the population in narrow shore line zones that are relatively easy to define and treat 4 15 |
