I Haven't Seen These Yet, But They're Only A Mile Away, Or So, So I Will

A well-established and reproducing population of brown marmorated stink bugs (BSMB) has been found in a Midtown Sacramento neighborhood, reported Chuck Ingels, UC Cooperative Extension advisor for Sacramento County. The infestation seems to be centered around 13th St., south of Capital Park. This is the first reproducing population in California outside Los Angeles County.

...“This is the worst invasive pest we’ve ever had in California, but there is no funding to attempt to eradicate it, nor is there a mandate to do so,” Ingels said.

Brown marmorated stink bug affects many different crops and is a serious residential problem. It moves around easily, so can be expected to spread. It can fly up to a half mile at a time and also travels long distances by hitching rides in vehicles or inside furniture or other articles when they are moved, often during winter months. As a result, most new infestations are found in urban areas.

Brown marmorated stink bugs are native to China, Japan and Korea. They were first documented in the United States in Pennsylvania in 2001, but was likely established there several years earlier. ... The pest has been present in Los Angeles County for 6 years.

BMSB feeds on dozens of California crops, including apples, pears, cherries, peaches, melons, corn, tomatoes, berries and grapes. Feeding on fruit creates pock marks and distortions that make the fruit unmarketable.

...In addition to the damage caused by the BMSB feeding, the “true bug” can cause disturbing problems for homeowners in the winter. When the weather cools down, bugs migrate in droves to sheltered areas, including inside homes and buildings.

...“Because they are strong fliers, it’s just a matter of time before they reach farms,” Ingels said.

The pest can be distinguished from ordinary brown stink bugs by its larger size, marble-like coloring on its shield and white markings on the extended edge of the abdomen. BSMB also has distinctive white bands on the antennae and legs.
