A new insect has been found in Minnesota

The Minnesota Department of Agriculture (MDA) has reported the first case of the purple carrot seed moth (Depressaria depressana), an invasive plant-feeding insect in the carrot family.

In a press release from MDA the insect says, “It feeds on plants in the carrot family, such as dill, fennel, and coriander.”

“I live nearby” Still water The insect was first noticed on dill plants and reported to the MDA. ”

“Second report from Montgomery Came a few days later. With help from the University of Wisconsin Diagnostic Laboratory, the scientists were able to establish the identity from the images.”

“The moth is native to Western Europe, Russia and China. It was first discovered in North America in 2008. It has been documented in southern Canada, Michigan, Indiana and Illinois. It was most recently discovered in Wisconsin in 2018 and Iowa in 2020.”

“The effect of this insect is currently unknown but because it is associated with flowers and not plant roots on carrots, the effect of celery and parsnip should be minimal,” says Engin Amborne, supervisor of the pest detection unit at MDA.

“Crops typically grown for seed such as fennel, dill and coriander may be where we see the greatest impact.” she says.

The MDA news release continues, “Purple carrot seed larvae are dark, distinctive and can be green or reddish with many white spots on their bodies. The larvae feed on flowers but also attach the flower parts to a webbing and can render herbs such as dill unusable.

The larvae are excreted in the belt and appear after a short period as small grayish-purple months.

“Because this is the first reported discovery of the purple carrot seed moth in Minnesota, MDA would like to better understand where this insect is in the state and how important this problem is to local gardeners.”
