Fall Webworm
Fall webworm lives as a group of caterpillars that spin a
communal silk web. This silk nest typically encloses the end of the branch and
associated leaves. The caterpillars remain in the webbing, feeding on these
enclosed leaves. When the leaves inside the web are eaten, the silk webbing is
expanded to include more leaves.

Turf Insecticides and Pollinators
Insecticides, particularly neonicotinoids, have been
receiving some heavy hits recently about effects on honey bees and other
pollinating insects. Other pollinating insects include bumblebees, sweat bees,
ground bees, flower flies, bee flies, butterflies, moths, and various beetles.
Last week, I attended the National Turfgrass Entomology Workshop held in South
Kingston, Rhode Island where this topic came up.

Turfgrass Rust
Turf rust outbreaks are commonly seen in late summer to
early fall as moderate temperatures and long evening dew periods occur. Rust
diseases are most severe on slow growing turf stressed by drought, summer heat,
low-fertility, shade or compaction. From a distance, severely infected turf
appears thin and tinted yellow, red, or brown. Closer inspection will reveal
individual blades with numerous yellow orange pustules.

New Plant Diagnostic Sample Submission App
The Plant Diagnostic Sample Submission App is a joint
effort to provide a way to easily submit digital images of plant problems or
pests on the go. This App is available for iOS and available for free download
in the iTunes store. Farmers, homeowners, greenhouse and nursery growers,
agricultural specialists and others now have a new mobile application resource
to identify plants, plant diseases, insect pests and other plant problems.

Modified Growing Degree Days (Base 50°F, March 1
through August 22)
Insect development is temperature dependent. We can use
degree days to help predict insect emergence and activity.

Invasive Species Roundup
Spotted wing drosophila, brown marmorated stink bug, and
thousand cankers disease are discussed this week.
