Monthly preventive sprayings and dustings for cockroaches and ants are among the pest control industry's biggest businesses. Experts agree that ridding homes and restaurants of cockroaches would cut down the incidence of food poisoning. "If (cockroaches) were to walk over a sewer or over a dead animal, and they were to walk into your house, they would carry certain organisms" on their feet, said Frank Hall, a vermin expert with the Los Angeles County Department of Health Services.

Re "Frog eggs head up the hill," March 13 Efforts to reintroduce red-legged frogs to the Santa Monica Mountains are crucial to assuring the future of these California natives once common in the state. The population of red-legged frogs has declined by more than 90%. Since red-legged frogs gained federal Endangered Species Act protection, we've learned much about threats to our struggling amphibian populations, none more prevalent than the 200 million pounds of pesticides applied to California crops annually, some of which drifts into the frogs' mountain habitats.

Read the comments of the president of California Citrus Mutual (letter, June 5). Farmers still defend the use of pesticides and soil chemicals, but the fact remains that they are hazardous! Consumers are becoming increasingly health and safety conscious and want no risks! No one knows each person's tolerance level, or how much poison he actually consumes each day. The intelligent decision is to avoid pesticide consumption! ELSA COSLETT Woodland Hills

SACRAMENTO - California farmers markets want to get tough with interlopers who don't sell what they grow. They're backing a bill to crack down on vendors who falsely claim to offer pesticide-free or locally grown fruits, nuts and vegetables. "Californians are fortunate to have the highest concentration of farmers markets in the nation," said the bill's author, Assemblyman Roger Dickinson (D-Sacramento). The bill, AB 1871, he said, would "increase consumer protections and accountability at our certified farmers markets, protect local farmers and help this growing sector of the economy continue to thrive.

New research pointing to a possible link between pesticides and Parkinson's disease validates citizens' concern that we examine with greater care any chemical that is released into our atmosphere--especially near our homes, schools and workplaces. Our young people in Ventura County are extremely vulnerable, with active agricultural fields right up to the borders of school grounds. In the case of Rio Mesa High School, the Environmental Working Group states that more than 100,000 pounds of pesticides prohibited from use in organic farming were used within 1 1/2 miles of the school in 1995--and the chemical use is increasing at an alarming rate.

The plight of bees is headed to a courtroom. A coalition of beekeepers, environmentalists and consumer groups filed a lawsuit against the Environmental Protection Agency this week, contending the agency has not done enough to protect bees from pesticides, which they say are linked to the increasing bee-colony collapse problem. The suit, filed by the Center for Food Safety, says the class of insecticides known as neonicotinoids are improperly regulated. The group calls for halting the use of the  pesticide until more is known about the effects on bees and other pollinators.

An environmental group resigned in frustration from a White House panel studying how to phase out use of toxic pesticides. The Environmental Working Group, a nonprofit organization, said the panel "has produced absolutely nothing" to reduce the health risks of pesticides for the nation's children. The panel was appointed by Vice President Al Gore after farm and industry groups complained that the EPA was moving too quickly to ban pesticides.

Some environmentalists say: Certain herbicides and pesticides used to kill weeds and bugs on lawns are potentially hazardous to humans as well as to pets. Heavy exposure during agricultural use has been linked to neurological and reproductive problems in humans, to liver and kidney disease and sometimes to cancer. Of 232 ingredients registered for use on lawns, about 60 have the potential to cause serious bodily harm, depending on length of exposure and concentration.

In Kevin Postema's Apartment Life column of July 16, there was a letter from an apartment dweller who was unhappy that his/her landlord would not apply pesticides. It goes to show you a landlord can't please everybody. Chemically sensitive, ill or anti-pesticide tenants would equally object if pesticides were used. The letter-writer needs to recognize that there are many people who do not want to have their apartments clouded with pesticides and should learn the many methods to fight insect pests without pesticides.

Scientists have discovered a link between DDT and Alzheimer's disease. In a small but intriguing study, researchers found that, on average, people with Alzheimer's disease had more of the DDT metabolite DDE in their blood serum than a control group in a similar age range. "DDE can last in the body for a number of years," said lead author Jason Richardson of Rutgers-Robert Wood Johnson Medical School. "When you are looking at DDE levels, it is basically a snapshot of a person's lifetime exposure to DDT as well as DDE in the environment.

We're not exactly sure why two Los Angeles councilmen are proposing a ban on growing genetically engineered crops or selling the seeds in the city. Maybe that's because they don't seem all that clear on the matter themselves. So far as anyone knows, there are no plants grown in the city whose DNA was tinkered with in a laboratory, according to spokesmen for the two council members, Paul Koretz and Mitch O'Farrell. Nor does anyone have plans to grow them. Bioengineered seeds are generally sold to large agricultural operations, the type that an urban center doesn't have.

Americans might soon need to get used to apple or grape juice as their breakfast drink of choice - unless, that is, they're willing to pay exorbitant prices for orange juice. Or maybe scientists, plant breeders and farmers will manage to save the day, using two critical but often-disparaged technologies: chemical pesticides in the short run and genetic engineering in the longer term. The pestilence that is devastating Florida citrus is a disease called citrus greening. It is caused by a bacterium, Candidatus Liberibacter asiaticus , which is spread by small insects called psyllids.

NEW DELHI - The principal at an Indian elementary school where 23 children died last week after eating free lunches contaminated with pesticide was arrested Wednesday on murder and criminal conspiracy charges after eight days on the run. Principal Meena Devi, 35, was caught in Chhapra, the city where the tragedy occurred in India's impoverished northern state of Bihar. On July 16, about 50 children - most younger than 10 - attending Dharmasati Gandaman Primary School complained of feeling sick after eating their lunch, which was provided free under a national government program that feeds an estimated 120 million children.

Pesticides sprayed on crops could be making honey bees susceptible to a fatal parasite and contributing to recent declines in bee populations, according to a study. Researchers found 35 pesticides, some at lethal levels, in the pollen collected from bees servicing major food crops in five states, including California, according to the study published online Wednesday in the journal PLOS One. Levels for two chemicals were above the dose that would kill half a population within two days, according to the report.

The illegal marijuana-growing operations that have proliferated in remote areas of the Sierra Nevada appear to be taking a toll on the fisher, a forest animal whose numbers are dangerously low. Researchers studying fishers in the Sierra National Forest in the southern Sierra found that mortality rates were significantly higher for females living in areas with a number of marijuana-growing sites. Liberal amounts of pesticides and anticoagulant rodent poison are commonly used at the operations, tainting small prey the fisher eats.

State officials in Oregon are temporarily restricting the use of more than a dozen pesticide products following the deaths of an estimated 50,000 bumblebees in the Portland area this month. The measure, effective immediately, will last for 180 days while the Oregon State Agricultural Department investigates incidents of a mass bee die-off in the Portland suburb of Wilsonville , and a much smaller die-off in neighboring Hillsboro. Eighteen pesticide products containing the active ingredient dinotefuran and used for ornamental, turf and agricultural applications have been banned for now. “I have directed the agency to take this step in an effort to minimize any potential for additional incidents involving bee deaths connected to pesticide products with this active ingredient until such time as our investigation is completed and we have more information,” the agency's director, Katy Coba, said in a statement released Thursday.

A pesticide used to control aphids has been singled out as the cause in this week's deaths of tens of thousands of bumblebees in a retail parking lot in Oregon, state officials said Friday. At least 25,000 bees were found dead and more were dying in a  Target  parking lot in Wilsonville, about 18 miles southwest of Portland, in what experts have described as the largest known die-off of bees in the United States. Witnesses reported bees falling from trees and littering the ground.
