Identify the Species
There are a range of black bugs that can infest cherry trees, making it necessary to identify them prior to taking action. In the USA, both Wooly and Oblique-banded Cherry Fruitworms have been known to cause significant damage to cherry trees. The Wooly Cherry Fruitworm is small, greenish and is covered in hairs. On the other hand, the Oblique-Banded Cherry Fruitworm has pinkish speckled markings along the body.
To ensure that the correct species is being treated, it is important to seek advice from a local extension office or Fruit Growers Association. They will be able to provide more information regarding the species that are present, life cycles and the likely damage that they can do.
Using Chemical Treatments
Chemical treatments can be an effective way of eliminating black bugs from cherry trees. Tree-based products may be applied early in the season, typically in late winter or early spring, to kill the black bug larvae during their growing season. These treatments need to be applied as outlined on the product instructions, as over application of these chemicals may damage the tree.
In order to get the best results from chemical treatments, it is important to understand the local tree population, as well as the season in which the black bugs are present. For example, it is easy for a large colony to emerge shortly after treatment and begin feeding on the cherry tree.
Using Organic Pesticides
Organic pesticides can also be used to get rid of black bugs on cherry trees. There are a range of products available which are designed to kill both larvae and adult black bugs. These products contain natural ingredients, such as neem oil, that quickly break down in the environment and are generally considered to be safe for both the environment and human health. When it comes to organic pesticides, it is important to read and understand the instructions on the product before application, as different organic treatments may have different effects on the tree.
Organic Insect Controls
Organic insect controls can be used to help reduce the number of black bugs on cherry trees. These include methods such as manually removing black bugs from the tree, using sticky traps and using beneficial insects such as lady beetles to feed on black bug larvae.
Manual removal of black bugs requires careful attention and is generally not suitable for large infestations. This is because the bug population can quickly rebound when left unattended. Sticky traps can also be set up around the tree in order to capture adult black bugs.
Beneficial insects such as lady beetles are natural predators of black bugs, and may be released into the environment in order to reduce the number of these pests. However, it is important to note that this should only be done in consultation with an expert in order to ensure that the lady beetles do not cause further damage to the tree.
Update Pruning & Growing Practices
By updating pruning and growing practices, it is possible to reduce the risk of black bug infestations on cherry trees. Pruning should be done correctly, removing dead or dying branches, in order to reduce the amount of harbourage areas for black bugs. Mulching around the tree also helps to reduce the attraction of black bugs, as they are attracted to moist, warm conditions.
It is also important to ensure that cherry trees are provided with adequate water and nutrients in order to ensure that they remain healthy. Healthy trees are far less likely to be affected by black bug infestations.
Monitor & Preventative Measures
In order to prevent an infestation of black bugs on cherry trees, it is important to monitor the tree’s health regularly. This should include a regular inspection of the foliage and branches for signs of black bug presence and damage.
If any black bugs are spotted, it is important to take action immediately in order to prevent a full infestation. Planting natural predators of black bugs, such as lady beetles, around the tree can be an effective tool for keeping infestation levels in check.
Conclusion
In order to get rid of black bugs on cherry trees, it is important to first identify the species of black bug present. This will help inform the decision-making process when it comes to selecting an appropriate treatment for the infestation.
Chemical and organic treatments can both be effective ways of eliminating black bugs from cherry trees, but it is important to ensure that the instructions on the product are followed carefully and to use them in combination with other measures such as manual removal and beneficial insect predators.
Finally, it is important to monitor the trees regularly and to update pruning and growing practices in order to reduce the chances of further infestations. With the right management techniques, it is possible to keep black bug infestations at bay.
