Pine bark beetles


There are numerous species of Ips Engraver and Dendroctonus, Bark Beetles, that infest conifers throughout North America. Adults tunnel through the bark, mate and lay eggs in the phloem (inner bark). The larvae develop in the phloem and cambial region; pupal development is completed in the inner or outer bark. Adults develop from pupae and emerge by boring out through the bark. Multiple generations a year are possible


Symptoms of infestation include: pitch tubes, reddish boring dust, adult exit holes, and yellowing foliage. The beetles commonly attack drought stressed trees. High number of attacks to trees are possible, which can result in extensive vascular injury and ultimately, tree death.


TREE-äge ® Insecticide (containing 4% Emamect in  Benzoate ) is the recommended treatment for Bark Beetles including Ips Engraver Beetles, Mountain Pine Beetles, Southern Pine Beetles, Spruce Beetles and Western Pine Beetles. TREE -äge provides 2 years of control for labeled Bark Beetles. The TREE I.V. system is recommended for treating Bark Beetles due to the nature of the host trees.

Dosages are based on the Diameter (in inches) of the tree at Breast Height (DBH”). Resinous Conifers: In resinous conifers, such as pine and spruce, start the injection immediately after drilling into the sapwood. A prolonged delay may reduce uptake on account of resin flow into the opening.


Effective injection treatment is favored by a full canopy (i.e., leaves) and a healthy vascular system. Once these tissues are compromised by insect damage (adult and larval galleries) an effective and uniform application of TREE-äge may be difficult to achieve and subsequent control may be poor. Optimally, treatment should be made preventively at least 2 to 3 weeks before Bark Beetles historically infest the host tree.

TREE-äge may also be effective as a remedial treatment against some pests, such as those with slower development or if multiple life stages are susceptible to TREE-äge


Research studies using TREE-äge (containing 4% Emamectin Benzoate) have demonstrated effective results against conifer bark beetles, depending on the pest species targeted. You can expect TREE-äge to be systemically distributed throughout the tree and provide protection from Bark Beetle pests for up to 2 years.

3 Considerations When Adding a Tree to Your Landscape

1.)How Trees Are Measured and Sold

Trees are typically measured for sale using 3 different methods: “Pot/Container size” (in gallons), “Height” (in feet; or in inches for small trees), and “Caliber” (in inches). Caliber is the diameter of the tree trunk, measured at about 6 inches off the ground. Sometimes trees are also measured using the Diameter at Breast Height (also known as “DBH”), but typically DBH is used for tree analysis purposes.

Trees are often sold in ball and burlap form or “B&B”. B&B trees can be measured using height or caliper. Trees are also sold in containers or pots which can be “container-grown” or “containerized.” Usually trees in containers are measured by the number of gallons their potholds. However, it is also perfectly normal for tree farms or nurseries to measure their trees in containers using caliper or height.

The industry standard for most trees would be 6 feet tall, 1-1.5” caliber, or a 15-gallon container. Rarely is anything easy to compare when dealing with plants. Actual sizes, heights, and caliberscan significantly vary based on species, grower, supply/demand, recent weather events, and many more factors.

2.)The Best Time to Plant Trees in Missouri

The best time to plant trees in Missouri is usually October through March. That said, most trees in our area can be planted all year long. Summer planting can create more difficulty establishing the roots of the tree, but proper watering is all it takes to keep trees alive.

3.)Placement & Space Requirements

Some trees grow different heights and widths based on the region in which they are located. It is important to know the mature size of your trees. Certain trees should not be planted nearoverhead power lines, concrete driveways/sidewalks, or the house’s foundation. On the other hand, some trees are small enough to grow under power lines, near concrete, and next to a house.

Locating trees in a spot with adequate space relative to their growth habit is essential to long-term health and wellness. Too much competition can prevent a tree from acquiring appropriate amounts of nutrients, water, and oxygen due to restricted areas for root growth and nutrientuptake. This lack of space leads to extra stress on the plant. Plant stressors can facilitate insect infestation and disease development. Adequate space and airflow make a significant difference in the quality of life for a tree.

Putting plants too close together also limits airflow. The lack of air movement prevents foliage and roots from drying out, which increases the plants susceptibility to fungal diseases

Emerald Ash Borer 2015 Update – Lawn Care Services Springfield MO

Emerald Ash Borer is a type of inset that is known to be suspicious and can infest a county. While they affect a county, there are multiple homeowners that are affected in their infestation process. Because of this we offer many lawn care services to homeowners within counties that have been affected by Emerald Ash Borer. The following insect information comes from a 2015 Insect & Disease Workshop (in January) and is compliments of Rob Lawrence, Forest Entomologist at the Missouri Department of Conservation:

Emerald Ash Borer (EAB) Information:





To Report EAB Suspicions for your county in Missouri, take the following steps:

1.) Check the map of known EAB infested counties @  www.eab.missouri.edu

If your county is already known to be infested, you can stop there.  If not, continue on to step 2.

2.) Compare EAB signs and symptoms from brochures available at the Missouri Conservation Department or www.eab.missouri.edu

If your signs and symptoms match those of EAB, continue on to step 3.

3.) Report your findings to your local Missouri Department of Conservation forester (See local contact box at http://mdc.mo.gov), by phone toll-free at 866-716-9974, or @ www.eab.missouri.edu
