occur on and in many Texas trees; however, rarely does one infestation lead to
permanent damage or death. Insect populations are cyclical. Some years insect
populations are high while other years you may not even notice them. Primary
environmental stresses like heat, drought, flooding, lightning, animal damage,
construction damage, soil compaction and wildfire can expose trees to additional
insect damage. Often the best way to prevent damage from periodic infestations
is to keep trees healthy.
Integrated Pest Management relies on a combination
of common-sense practices. IPM takes advantage of pesticide applications,
mechanical methods and biological controls. Sometimes the appropriate method may
be no control at all. The four steps of IPM are: Set Action Thresholds, Identify
and Monitor Pests, Prevention and Control. More information is available at
Insects and diseases together are responsible for
killing two out of every three trees that die. Healthy trees are much less
susceptible to insect and disease damage. Many times it is the activities of
people that compromise the health of trees and make them vulnerable to insects
and diseases. This is especially true in urban areas.
Insects can be defoliators, borers or sucking
insects and can transmit tree diseases. Defoliator insects or their larvae eat
leaves. Borers attack a tree’s water and nutrient transport system. Sucking
insects feed on plant juices from leaves and twigs. Many insects also feed on
wood; however, this usually happens on already sick, dying or dead trees.
May 2016 - The emerald ash borer beetle
that has killed tens of millions of ash trees across the United States has been
detected in Texas. EAB is a non-native, invasive insect that has the potential
to wipe out all ash species in Texas—seriously
affecting rural and urban ecosystems. Texas A&M Forest Service is helping
people and communities prepare.
