North Carolina wine crops face beetlemania

Aug 08 ,General Science


North Carolina grape growers who have dealt with hurricanes, tornadoes, fungi and birds now face another threat: Japanese beetles.

Japanese beetles are most drawn to such crops as apples and sweet corn, but vineyards have been hard hit this year because of above normal rainfall that has helped spawn millions of beetles, the Raleigh (N.C.) News & Observer reported Monday.

The beetles don't eat grapes, since the insects are gone before the grapes ripen. But the beetles "skeletonize" grape leaves, eating everything but the veins, the News & Observer said.

Without leaves the vines cannot make flowers and fruit to reproduce or store energy for winter, so the plants die.

Vineyards in western states don't have the problem, since the Mississippi River seems to have kept the beetles from moving west, the newspaper said. European wine regions also don't have beetle problems.

Ladybugs may look pretty but they also have a dark side. In some places, the polka-dotted insects have become a nuisance by invading homes and crops, including some vineyards. To make matters worse, the bugs produce a foul-smelling liquid that, besides irritating homeowners, can be inadvertently processed along with grapes and taint the aroma and flavor of wine.

The delicate lady bug in your garden could be frighteningly large if only there was a greater concentration of oxygen in the air, a new study concludes. The study adds support to the theory that some insects were much larger during the late Paleozoic period because they had a much richer oxygen supply, said the study’s lead author Alexander Kaiser.

Diversity is valuable socially, economically and now environmentally.
