Pink Hibiscus Mealybugs
Texas Department of Agriculture (TDA) collected 20 suspect mealybug
samples from approximately two square miles surrounding a Pearland
home. Of these 20 samples, six were confirmed as the pink hibiscus
mealybug. TDA will initiate a similar survey around a southwest
Houston home where the other mealy bug was detected to determine
the extent of infestation.
Once infestation is determined, inspectors will control the pest
using a biological method – parasitic wasps. Research has
shown these parasitic insects are the best method to control mealybugs,
resulting in a 90 percent success rate. The tiny wasps will only
attack the mealybugs, not humans or pets.
Treatment for mealybugs should avoid using insecticides, as they
are usually ineffective and could harm beneficial insects. Instead
prune off the most heavily infested plant parts, place in sealed
bags and dispose in garbage.

Chili thrips An inspection
of the MD Anderson Cancer Center in Houston revealed chilli thrips
or signs
of chilli thrips damage at each bed. Inspection of a bed of Knock
Out roses a couple of miles away from the Medical Center also found
chilli thrips. Scott Ludwig of Texas AgriLife Extension is updating
a homeowner information fact sheet on chilli thrips to include the
latest efficacy results from the work he is conducting with USDA-APHIS.
He is also working on management recommendations for professional
landscapers. This information will be available at http://chillithrips.tamu.edu/.
Dr. Ludwig will address this topic during a session at the the educational
lounge at the Nursery/Landscape
Expo.
