A mild winter and heavy spring rains across much of the country have led to predictions that the mosquito-borne West Nile virus, which killed 284 Americans last year, will be even worse this summer. But while West Nile prevention and surveillance programs are heating up around the country, mosquito breeding depends on capricious factors like local ecological systems, making it difficult to tell how bad this year's infestation will ultimately be. But West Nile — bearing mosquitoes are hardly the only pests looking to have a big summer.

MORMON CRICKETS The worst cricket year in decades is devastating millions of acres of farmland in Utah and other Western states. Snowplows are out clearing roads made as slick as ice with crushed insects
