(Pierre-AP) -- The state Health Department says 90 to 100 percent of the mosquitoes were killed during aerial spraying in 16 communities last month.

It bases its conclusion on the mortality rate of caged mosquitoes that were exposed to the spray compared to another group of mosquitoes that were protected from the spray.

The state hired a company to spray 110-thousand acres because of the high number of West Nile cases. Mosquitoes spread the disease.

Lon Kightlinger in the Health Department says communities must start planning now for how they'll control mosquitoes next year.

(Yankton-AP) -- The South Dakota Supreme Court will consider arguments today at Yankton in a case involving a tragic graduation party at Winner.

The all-night beer bash in 2000 ended in the death of 18-year-old Caz Welch of Winner -- who had just received his high school diploma hours earlier.

Welch was riding in a van that ran off the road -- pinning him between the seat and roof. He suffocated at the scene.

His grandfather sued the young driver, his mother and a farm couple who allowed the party on their property. But a jury refused to find them negligent.

The justices -- who are meeting today at Mount Marty College for their fall term -- also are considering a case involving two Miner County hunting guides who were caught in an undercover sting.

The guides are challenging their convictions and the 20 days a year that they must spend in jail -- beginning the day before pheasant season.

(Sioux Falls-AP) -- Warm, dry weather last week aided the fall harvest in South Dakota.

The weekly crop report shows 18 percent of the corn, 47 percent of the soybeans and 32 percent of the sunflowers had been harvested as of Sunday. That's equal to or slightly ahead of the ten-year average.

Seeding of winter wheat and winter rye is about normal for this time of year, but the dry weather is slowing emergence of both crops.

Only 25 percent of the state has enough topsoil moisture. An eleven-county area in the southeast is the only part of the state with enough moisture.

(Madison-AP) -- A January 27th trial is scheduled for 55-year-old William C. Rush of Wentworth, who pleaded not guilty to second-degree manslaughter and assault in the death of 72-year-old Bill Newcomb of Madison.

The announcement comes not long after Gateway computer announced that it's cutting jobs at its North Sioux City plant.
