Japanese beetles are a destructive species of insect that feed on the foliage of many types of plants. Unfortunately, tomato plants are susceptible to Japanese beetle damage. The beetles feed on the leaves and flowers of tomato plants, leaving behind skeletonized foliage and damaged fruit. Fortunately, there are steps that can be taken to control and prevent Japanese beetle damage on tomato plants.Japanese Beetles feed on the leaves, flowers, and fruits of over 300 species of plants. They are especially fond of roses, grapes, lindens, and crepe myrtles. They are also known to feed on beans, raspberries, and various shrubs.
What Damage Do Japanese Beetles Cause?
Japanese beetles are a destructive pest that can cause significant damage to plants in gardens and landscapes. The adult beetles feed on the foliage, flowers, and fruits of over 300 different plants, including trees, shrubs, vegetables, and ornamental plants. The larvae (grubs) feed on the roots of grasses and other plants. Japanese beetle damage includes skeletonizing of leaves, which means that only the veins remain; complete defoliation; and a hairy appearance caused by the larvae. The damage caused by Japanese beetles is often more severe on weakened or stressed plants.
The presence of Japanese beetles can also have an aesthetic effect on plants and gardens, making them unsightly. In addition to feeding damage, adult beetles can cause physical damage by mating and laying eggs in turfgrass areas. Female beetles will chew small holes in turfgrass to lay their eggs; this is known as “windowpane injury” because it leaves a characteristic window-like pattern on the turfgrass.
How To Identify Japanese Beetles
Japanese Beetles are a common pest found in the United States and Canada. They have a unique shape and color, making them easy to identify. The Japanese Beetle has a metallic green body with copper-colored wings. It has six white tufts of hair along the outer edges of its body and four tufts of white hair along its underside. Its legs are short and black, and its antennae are long and thin.
When identifying Japanese Beetles, it is important to look for their characteristic markings. They have a distinctive oval shape with ridges along the upper surface of their body. The head is rounded, and there are two small bumps at the tip of each antennae. They also have rows of small white spots along their back that form an irregular pattern.
Japanese Beetles can be found in gardens, fields, orchards, woodlands, grassy areas, and other outdoor locations where there is plenty of foliage to feed on. They often feed on flowers, fruits, vegetables, and shrubs during the day and hide in nearby vegetation at night. When infested with Japanese Beetle larvae, plants may become defoliated or suffer from root damage or dieback due to heavy feeding by the larvae.
The best way to control Japanese Beetles is to inspect plants regularly for signs of infestation and to remove any beetles you find by hand or with a vacuum cleaner. You can also apply insecticides that are specifically labeled for use against Japanese Beetles when necessary. Contact your local Extension office for more information about management options for controlling this pest in your area.
By understanding how to identify Japanese Beetles and taking steps to keep them from damaging your plants or garden, you can help keep your plants healthy and thriving all season long!
Prevent Japanese Beetles From Eating Tomato Plants
Japanese beetles can be a destructive pest that can wreak havoc on your beloved tomato plants. While it may seem like an insurmountable task to prevent them from eating your plants, there are several steps you can take to reduce their impact and keep your tomatoes safe.
One of the most effective methods for preventing Japanese beetles from eating your plants is to use insecticide sprays or granules.

Natural Remedies For Treating Japanese Beetle Infestations
The Japanese beetle is an invasive species of insect that can wreak havoc on gardens and crops. The larvae feed on the roots of grasses and other plants, while the adult beetles feed on the leaves, flowers, and fruits of many plants. If you are dealing with a Japanese beetle infestation, there are several natural remedies you can use to get rid of them without resorting to chemical pesticides.
One of the most effective methods for controlling Japanese beetles is to introduce beneficial insects into your garden or landscape. Ladybugs, lacewings, and predatory mites all feed on Japanese beetle larvae and adults, helping to keep their populations in check. You can purchase these insects from garden centers or online retailers.
Another natural remedy for Japanese beetle infestations is to use traps that lure the beetles in with a sweet-smelling bait. These traps should be placed away from your garden or landscape so that they don’t attract more beetles than you can handle. Once the traps are full, dispose of them in a sealed plastic bag in a garbage can or compost bin.
A third option is to use beneficial nematodes as a natural way to control Japanese beetle populations. Beneficial nematodes are microscopic worms that feed on the larvae of many types of insects, including Japanese beetles. They can be purchased online or at garden centers and should be applied to your soil according to package directions for best results.
Finally, hand-picking is an effective way to reduce adult Japanese beetle populations in your garden or landscape. Wear gloves when picking up any beetles you find so you don’t get stung by their spines. Once collected, drop them into a container filled with soapy water; this will kill them quickly and effectively without using any chemicals.
Using these natural remedies can help you get rid of any existing Japanese beetle infestation without resorting to chemical pesticides that may harm other beneficial insects in your garden or landscape.
Chemical Solutions For Controlling Japanese Beetles On Tomato Plants
Controlling Japanese beetles on tomato plants can be a challenge. Fortunately, there are a few chemical solutions that can help eliminate these pests. One of the most effective is Sevin, a broad-spectrum insecticide that targets Japanese beetles. When applied to the foliage of tomato plants, it will kill both adult and larval stages of the pest. It is important to note that Sevin must be reapplied every seven to ten days as long as the beetle activity persists.
Another option is Malathion, an insecticide that targets numerous species of insects and mites. When used on tomato plants, it will kill adult Japanese beetles as well as any eggs that may have been laid in the soil around the plant’s roots. Malathion must be applied every seven to ten days until activity has ceased.
Finally, Neem oil is a natural solution for controlling Japanese beetles on tomato plants. Neem oil is derived from the seeds of the neem tree and contains active compounds that act as an insect repellent and disrupts the life cycle of many types of insects including Japanese beetles. To use neem oil for controlling Japanese beetles on tomato plants, it should be applied every seven to ten days until activity has stopped or decreased significantly.
Removing Japanese Beetles By Hand
Removing Japanese beetles by hand is an effective way to reduce the infestation of these pests in your garden or lawn. The first step is to locate the areas where they are present and then carefully remove the beetles using gloved hands. It is important to be careful when removing them as they can easily be crushed and spread their larvae further. Once you have removed the beetles, you can dispose of them in a sealed container or trash bag. This will prevent them from returning to your garden or lawn.
It is also important to note that Japanese beetles can lay eggs on plants, so it may be necessary to remove any larvae that may be present as well. To do this, you can use a pesticide or insecticide specifically designed for controlling Japanese beetle larvae. Additionally, you may need to prune back any affected plant parts in order to fully eradicate the infestation.
Finally, it is important to keep a close eye on your garden or lawn for signs of future infestations. If you see any new adults flying around, then you should immediately begin removing them by hand again. Regularly checking for signs of Japanese beetle activity will help prevent larger infestations from occurring in the future.
Overall, removing Japanese beetles by hand is an effective way of controlling their presence in your garden or lawn. If done regularly and diligently, it can effectively reduce their numbers and help keep your plants healthy and free from damage caused by these pests.
Are There Any Beneficial Insects That Eat Japanese Beetles?
Yes, there are several beneficial insects that eat Japanese Beetles. These include the larval stages of ladybugs, ground beetles, and green lacewings. Ladybugs, also known as ladybird beetles, feed on aphids and other soft-bodied insects like caterpillars. Ground beetles feed on small insect larvae and pupae, while green lacewings feed on aphids, whiteflies, mites, and other small insects. All of these beneficial insects can help to reduce the population of Japanese Beetles in your garden or yard.
In addition to predatory insects, there are also parasites that can be used to control Japanese Beetle populations. Parasitic wasps lay their eggs inside of the beetle larvae or pupae and when the eggs hatch the wasp larvae feed on the beetle larvae or pupae until they reach maturity. This type of biological control is a safe and effective way to keep Japanese Beetle populations in check without using chemical pesticides.
It is important to note that while beneficial insects can help reduce Japanese Beetle populations in your garden or yard, they should not be considered a replacement for proper pest management techniques such as hand-picking or using chemical insecticides when necessary. However, with proper care and maintenance these beneficial insects can provide a natural way to reduce the number of pests in your garden or yard.
