What is the Japanese beetle?

Japanese Beetle or Dopillia japonica is a member of the Beetle family, which has increased in the United States as a pest. Although the Japanese beetle has many predators who keep their numbers under control in native Japan, there are no natural predators in America. This lack of natural predators caused the Japanese beetle the ability to cause more than $ 450 million (USD).

Adult Japanese beetle is about 1/2 inch (11 mm) and a little below 1/4 inches (6 mm) wide. The body of the beetle is a deep metal green color, while the wings are polished copper. There are six white hair stains on each side of the abdomen on the Japanese beetle. The larvae are white, with long brown hair and short backbone. The life cycle of the Japanese beetle is between one and two years.P for about 300 types of plants. Adult beetles feed on different flowers, plant plants and other various leaves. In the larvae stage, Japanese beetles feed on a large number of roots and grasses. Combined habitY feeding Japanese beetle, from larvae to adults, giving him the ability to cause confusion in his habitat.

Common host plants for adult Japanese beetles include, but are not limited to plants carrying asparagus, some types of beans, citrus fruits, plums, raspberries, corn and maple trees. Other host plants include grass lawn, walnuts and Sassafras. The Japanese beetle usually primarily damages the leaves of the above plants and leaves only the frame of the leaf after feeding. The larvae will feed the roots of grass and other plants and damage the plants the ability to absorb nutrients and water. A common indicator of Japanese Beetle larva is dead grass spots or other leaves.

As with most invasive species, there are several methods to remove the infestation of the Japanese beetle. Specific application of these methods can have different degrees of success. For localized contamination can beBeetles physically removed from the plant. Traps can be placed that attract and kill beetles, but if they are used incorrectly, they can be more devastating than useful. Since most commercially available Japanese beetles are attracting beetles, they can also lead to a greater degree of contamination.

are available pesticides that are highly toxic to Japanese beetle. These pesticides bring different results. Since pests are very resistant to both poisons and physical damage, many previously successful pesticides have been considered unusable in recent years.
