Mosquitoes carrying West Nile virus and a strain of malaria have developed a resistance to insecticides because of a single-letter mutation in their genetic code, scientists said. Researchers at the University of Montpellier II in France said the alteration could be the cause of 25 years of resistance to insecticides among insects that carry the disease. The mutation makes a key enzyme in the mosquitoes less sensitive to ingredients in some insecticides.

The San Bernardino County town of Colton is the only city in the nation with an official, federally designated fly preserve. Hard as it may be to believe, this is not a distinction sought by city leaders, who can't imagine that the 10-acre, chain-link-ringed habitat of the tiny Delhi Sands flower-loving fly will ever challenge Mt. Slover, a 300-foot limestone peak owned by a cement company, as the city's major landmark.

"Opossum Killings Test Limits of Cruelty Cases" (July 29) did not educate enough about how harmless to humans opossums are and why they are desirable to have around our yards and homes. They are nocturnal, so coming across one in the dark is scary. They hiss and show their teeth when they are frightened, but they don't bite humans. Indeed, if humans get too close, they freeze and appear to be dead, i.e., "play possum." This actually is an involuntary, shock-like state. I decided not to bother with traps or any efforts to remove them from hanging around my yard in the middle of Los Angeles when I learned that they dine on insects, cockroaches, snails, mice, rats and occasionally snakes.

This is a story about a bug, a bird and a tree. The bug is a tiny caterpillar, the western spruce budworm, eating its way through eastern Washington forests. The tree is the Douglas fir, the budworm's favorite meal. The bird is the northern spotted owl, a federally protected species that frequents the same forests the budworms are devouring. Put them together and you get another story--a story about how hard it is to correct the damage when humans tamper with Mother Nature.

Bayer said Tuesday that it has agreed to buy Aventis CropScience for about $4.9 billion in cash to become the biggest maker of insecticides and help replace lost income from the withdrawn cholesterol treatment Baycol. The purchase from Aventis and Schering will yield annual savings of about 500 million euros with an elimination of 4,000 jobs, Bayer Chief Executive Manfred Schneider said at a news conference. The company also will assume $1.

Cracking down on illegal insecticide sales, the Environmental Protection Agency on Wednesday announced more than $200,000 in fines against 15 stores that sold toxic pest killers that look like candy and blackboard chalk. Many are Asian markets, and six are in Los Angeles County. "In the case of some of the mothballs, they literally look like big bubble gum balls," said Leo Kay, a spokesman in the federal agency's San Francisco office.
