Japanese beetles are one the most devastating pests of urban landscape plants in the Eastern United States. Obion County University of Tennessee Extension Service office director Tim Smith said, ?EUR??,,????'?????<????????Droves of these insects are devastating our plants.?EUR??,,????'?????<???????? Tenessee resident Margie Smith reported that she has killed enough Japanese beetles to almost fill a garbage can. She said she sprayed an insecticide one day and as soon as the ones that she sprayed died, there were more to take their place.
Japanese beetles feed on about 300 species of plants, devouring leaves, flowers and overripe or wounded fruit. They usually feed in groups, starting at the top of a plant and working downward. The beetles are most active on warm, sunny days and prefer plants that are in direct sunlight. A single beetle does not eat much; it is group feeding by many beetles that results in severe damage.
Many insecticides are labeled for use against adult Japanese beetles. It is important to check the ingredients and make sure that the insecticide will rid your landscape of the beetles, but at the same time be safe enough to use on your plants.
