What Happens When Japanese Beetles Eat Tomato Plants

Many homeowners and gardeners wonder if Japanese beetles eat tomato plants. So, what happens if they eat the plants?

As we already know, Japanese beetles love to eat the leaves of tomato plants. They attack the veins of the leaves. As a result, they create several unhealthy brown patches on the leaves. This can severely damage the whole plant.

When adult Japanese beetles attack your tomato plants, you will notice a lace-like pattern on the leaves. This happens because the beetles feed on the tissue that lies between major leaf veins.

As a result, they end up skeletonizing the tomato leaves. This damages the structure and health of the leaf. In the end, they may turn brown and fall off. At the same time, Japanese beetle grubs mostly attack the roots.

So, the ability of the tomato plant to take enough water and nutrients from the soil faces disruption. Many times, serious damage to the root can cause the plant to fall off. Your tomato plants will struggle to develop or sustain themselves when too many grubs attack their roots.

The damage caused by Japanese beetles on your yard, garden, and lawn can go as far as hindering their sustenance.

Especially if the infestation is too large, you will need to call in professionals to help you get rid of them. Tomato plants are herbs.

That is, they have soft and fragile stems. So, Japanese beetles can easily attack the leaves, resulting in the plant dying.
