The beetles are attracted to the trees’ sap, which they use to feed their larvae.
The Impact of the Shothole Borer
A Threat to the Local Ecosystem
The shothole borer poses a significant threat to the local ecosystem in Santa Clara County. The beetles’ ability to tunnel into trees and introduce a fungus that causes disease has far-reaching consequences for the environment. Here are some of the key impacts:
The Devastating Impact of the Emerald Ash Borer
The Emerald Ash Borer (EAB) is a non-native insect pest that has ravaged the ash tree populations across North America. This beetle’s impact on the environment and economy has been nothing short of catastrophic, with far-reaching consequences for the ecosystem and human societies.
A Brief History of the Emerald Ash Borer
The EAB was first detected in Michigan in 2002, and since then, it has spread rapidly across the continent, reaching as far as Canada and the northeastern United States. The beetle’s rapid spread can be attributed to its ability to lay eggs in the bark of ash trees, which hatch into larvae that feed on the tree’s vascular system, ultimately killing it.
Host Range and Impact
The EAB is capable of killing several species of trees, including:
In addition to these species, dozens of other tree and shrub species are known to host the invasive beetle. The EAB’s impact on the environment is not limited to the trees themselves, but also affects the entire ecosystem.
These holes are usually found on the trunk or branches of the tree, and they can be a sign of a serious infestation.
Identifying the Signs of an Infested Tree
Identifying the signs of an infested tree can be challenging, but there are several key indicators to look out for. Here are some of the most common signs of an infested tree:

Tips for Success
Onions can be planted in the fall or early spring, but the ideal time is in the late summer or early fall, about 8 weeks before the first frost.
Choosing the Right Variety
When selecting an onion variety, there are several factors to consider.
Onions are a cool-season crop, which means they thrive in temperatures between 40°F and 70°F (4°C and 21°C). They can tolerate some frost but are sensitive to extreme heat and humidity.
Preparing the Soil
Before planting onions, it’s essential to prepare the soil. Onions require a well-drained and fertile soil to grow.
