Doug Landis
and colleagues compared native prairie and savanna plants with non-native
plants for their ability to attract beneficial insects. The team counted
number and kinds of insects visiting each plant species and noted the number
of open flowers along with flower color, nectar quantity and quality, and
pollen availability. If managing habitat can encourage natural predators,
growers can reduce their use of agricultural pesticides.
Since
grass doesn’t fare well under elaborate opening ceremonies at the Olympics,
a team led by
John Rogers designed a portable athletic field for Beijing this
summer. Within 48 hours of the ceremonies, they’ll install thousands of
interlocking four-foot-square sections of turf, each weighing more than 1000
pounds. They’ve also developed a joint education program on turfgrass
management with four Chinese universities.
Corn kernels are the source of most U.S. ethanol;
processing stalks and leaves to make the fuel is difficult and costly.
Mariam Sticklen developed a
series of corn genetic lines that grow the enzymes necessary to break down
cellulose and hemicellulose into simple sugars in their leaves. The Spartan
Corn series promises to make a waste product commercially viable and allow
farmers to sell stalks and leaves as well as kernels.
Photosynthetic
organisms—both plants and bacteria—grow and develop in response to their
environment, including changes in the color of the light. Cells of the
bacterium Fremyella diplosiphon can change from red to green and back
in response to changes from green light to red and back.
Beronda
Montgomery-Kaguri studies the molecular mechanism that controls that
adaptation designed to make the best use of available light.
Coddling moths are a major problem for apple growers,
and pheromones help control them by disrupting mating.
Larry Gut
and colleagues think the male moths spend their time following the synthetic
pheromone trails instead of females. Preventing mating for the first four
days after the moths emerge improves results. Dispersal in wax
droplets—about 100 per tree—proved to be the most effective and economical
application method. |
