Fragrant Fix Smell-Based Pheromones Offer
Pesticide-Free Bug Control
Semios, a Vancouver, Canada, provider of real-time agricultural information and preci- sion pest management tools, has been given U.S. Environmental Protection
Agency approval for the first aerosol pheromone-scent products shown ef- fective in disrupting the mating of the codling moth and oriental fruit moth by attracting males to the females’ scent in spots devoid of mates. Pheromones are natural chemicals that many animals use to communicate within their species. Unlike pesticides that kill a wide
variety of insects, each pheromone targets a single pest species, leaving beneficial pollinators like bees and predators such as ladybugs unconfused and unharmed. One dispenser is hung in each acre and nothing is sprayed directly on the fruit. Phero- mones don’t affect any other organisms, including humans, and can be used by both organic and conventional growers. David Knight, owner of Knight’s Ap-
pleden Fruit, Ltd., in Colborne, Ontario, has used the Semios system for two sea- sons as part of a regulatory trial. He says, “I could see this technology becoming completely mainstream in our industry in the next five or six years.” Traditional insecticides are expen-
sive to buy and time-consuming and labor-intensive to apply. Because they’re toxic, workers can’t enter the orchard for a specified number of days after spraying. Knight adds that fruit growers that rely heavily on pollinators to produce their fruit are also keenly aware of the environ- mental risk posed by pesticides and wel- come a natural and less costly alternative; only tiny amounts are needed. Kirk Hillier, Ph.D., a biologist at
Canada’s Acadia University, in Nova Scotia, who studies how insects com- municate with pheromones, confirms that such scents have also been shown to be effective in both controlling a wider variety of agricultural and household pests and monitoring insects destructive to forests.

Bright Future Upbeat Forecast for Long-Term Emissions
New data from the U.S. Department of Energy shows that overall domestic energy consumption is slowing and isn’t expected to grow much over the next 25 years, despite a growing economy and population. Usage is forecast to rise 0.3 percent annually between now and 2040, or just half the expected population growth rate, and dramatically less than the 2.4 percent projections for economic growth through 2040. Greenhouse gas emissions from burning fossil fuels are expected to increase only 0.1 percent in the same period. Thanks to a public embrace of energy efficiency, residen-
tial fuel consumption may not grow at all over the next quarter-century. With more Americans driving electric and other energy-efficient vehicles, energy use in the transportation sector will decline slightly and gasoline consumption is expected to drop more than 20 percent by 2040. Industrial energy use is expected to grow at less than 1 percent.
To: Email: College students nationwide are supporting the reported progress by conduct-
ing divestment campaigns at universities, including Divest Harvard. At a recent event, alumni, including Bill McKibben, founder of
350.org, and former Colorado Senator Tim Wirth, joined students in protesting any investment of the school’s huge endowment fund in fossil fuel companies.
