Pest News Alert for Week of June 23rd


From: Steve Frank, Extension Entomologist

Flea Beetles

Redheaded flea beetles, Systena frontalis, have become a serious pest of nursery stock over the past several years. They are an especially damaging pest because they feed on roots and leaves. They overwinter as eggs in the soil. Larvae hatch in spring and begin feeding on roots. The larvae are elongate and creamy-white. Heavy infestations may reduce root mass or girdle plants. Adult redheaded flea beetles are small, shiny black, beetles with reddish to dark colored head and long antennae. They are about 1/16 of an inch long and, as the name suggests, jump when they are approached. There are at least two generations in Delaware and may be more in North Carolina.

Adults and adult feeding damage are present now. The favored hosts are Itea, hydrangea, forsythia, and knockout roses and many perennials like joe-pye weed. Adult management has been frustrating for growers who find that even frequent insecticide applications do not reduce adult abundance and damage to acceptable levels. Part of this has to do with not controlling larvae since even if you kill all the adults present in a crop (which you won’t) more adults are emerging from the soil every day. Research thus far in Delaware and grower reports indicate that Talstar, Sarfari, and Flagship provide good efficacy as foliar applications, but do not have long residual activity.

- One Western NC note-  typically these alerts are earlier than expected emergence here but this pest is very active on Knockout Roses this year and has been for over 10 days. 

Columbine Leafminer

The first round of flowering is about over for my native columbine, Aquilegia canadensis. Columbine is a great early spring flower that flowers profusely and spread easily by seed. Spring bees and humming birds visit columbine flowers particularly in early spring when it is one of the only flowers present.

The columbine leafminer, Phytomyza aquilegivora, overwinters as pupae. Adults emerge in early spring and oviposit in new columbine leaves. Small white maggots mine the leaves creating white or grey serpentine pathways. Often entire leaves are discolored. Larvae pupate after about 10 days on the underside of leaves. Columbine leafminer has at least 4 overlapping generations per year in North Carolina. There are at least 13 species of parasitoids that become more abundant as the summer progresses.

Braman et al. (2005) reported that the native species, A. canadensis, is more resistant to leafminers than many other species of cultivars. Removing and destroying infested leaves before adults emerge may help reduce damage to subsequent leaves. Leafminer control is often best to left the parasitoids become established and just accept some damage. If you are a grower, there are several insecticides available to help reduce leafminer damage.

New industry articles on spider mite and thrips management for greenhouses.

Periodically I publish articles in industry magazines such as Greenhouse Grower, GrowerTalks, and American Nurseryman. The two most recent articles discuss spider mite and thrips management. You can find these and all industry articles at:

Japanese Beetles

This pest feeds on roses, grapes, flowering plums and other plants during the mid summer and will begin to lay eggs fairly soon after the adults emerge.  Once the eggs are laid we can expect the Juvenile stage; white grubs to hatch within 2 weeks.   Adult beetles are already flying in large numbers in WNC.   Landscapers should consider applying an insect for the adults NOW!.  But turf grass managers need to consider starting applications of insects for the grubs in about 3 weeks.  A couple of very safe products can be considered; Acelepryn (an IGR from Sygenta) and the beneficial nematode- Heterorhabditis 
bacteriophora  can be used.  Both products will need multiple applications from mid July through September.   Mach 2 and Merit are also two very good insecticides however use caution when applying either of these due to potential for damage to pollinators.

IPM Workshop for Nursery Folk

IPM 2-day Workshop, Raleigh, NC. June 25-26, 2014.

The Southern Nursery IPM (SNIPM) Working Group recently received funding from the Southern IPM Center to present a hands-on, 2-day, professional development workshop focused on integrated pest management (IPM) for nursery crops to save resources, reduce pest damage and pesticide use, and create a safer working environment for employees.  The training costs $15, which includes snacks, lunch and beverages for two days, as well as training materials described below.


Horticulture Headhouse & Greenhouse Complex at the Horticultural Field Lab located behind the J.C Raulston Arboretum
Directions to Horticulture Headhouse & Greenhouse Complex

Wednesday     25 June 8:30 a.m. to 5 p.m.
Thursday        26 June, 8 a.m. to 5 p.m.

Training will include integrated management of diseases, arthropod pests, weeds, as well as cultural practices that influence pest management, and training on utilization of the IPMPro mobile device app.  Attendees will be taught insect, disease and weed identification techniques using live samples. 
Participants will receive a copy of IPMPro, Weeds of the Northeast, Weeds in Containers, and copy of the newly printed IPM for Shrubs in Southeastern U.S. Nursery Production, as well as other lecture handouts.  Those things alone are worth $200.
All participants will be given a pre- and post-workshop survey as well as a post-season survey (Nov 2014) to gauge learning, comprehension, and adoption of IPM practices. 
The training has been developed by the Southern Nursery IPM (SNIPM) Working Group - the same team that produced the IPMPro app, IPM Manual for Deciduous Trees, and the IPM Manual for Shrub Production.  Instructors will include Joe Neal, Steven Frank and Anthony LeBude from NCSU; Matthew Chappell and Kris Braman from Univ. of Georgia,  Sarah White and J.C. Chong from Clemson, and Nicole Gauthier from Univ. of KY.  We are all grateful for the assistance from the Southern Region IPM Center.

Pest News for week of June 9th


From: Steve Frank, Extension Entomologist

Gloomy Scale Crawlers are Active

Gloomy scale, Melanaspis tenebricosa, is an armored scale that is found on maples and other tree species. It becomes very abundant on landscape maples and can cause branch dieback and tree death in some cases. It is not unusual to find trees with nearly 100% of their trunk covered in scale. Street trees are particularly prone to gloomy scale. I have never found one that didn’t have it! Crawlers of this scale are active now and can be seen on bark and under scale covers. Control of this scale is complicated be-cause crawlers emerge over 6 to 8 weeks so it is impossible to treat all the crawlers at once with horticultural oil or other contact insecticide. This is as opposed to scale such as euonymus scale in which all crawlers are produced within a narrow window of two weeks or so. However, horticultural oil can still be applied to kill gloomy scale. We have tested several products against gloomy scale with mixed results. None provides consistent high levels of control. Products including Safari, TriStar, and Distance can provide some suppression. It is important to note that imidacloprid (e.g., Merit) is not effective on armored scale. More information on armored scale control can be found here (http://www.ces.ncsu.edu/depts/ent/notes/O&T/shrubs/note157/note157.html). Our home page (http://ecoipm.com/) has more information on our gloomy scale research program and a recent blog post. To see an overview of gloomy scale on urban trees watch our short video (https://www.youtube.com/watch?v=1Fg-ZPkJwRA&feature=youtu.be).

Crapemyrtle Aphids

Crapemyrtle aphids are one of the most common pests of crape myrtle, but rarely require treatment. Small populations are present in Raleigh and have been building over the past couple weeks. Feedings by these aphids result in leaf yellowing and distortion, leaf drop, and honeydew deposits which of course lead to sooty mold. Crapemyrtle aphids are generally kept in check by natural enemies. When scouting for them I often find almost as many lacewing eggs, lady bug larvae, and other predators as aphids. Interestingly, there are no known parasitoids of this exotic aphid. A variety of chemicals are available should these aphids reach unacceptable levels in nurseries or landscapes. Some of the same chemicals recommended for aphids such as imidacloprid can be applied as a drench to protect against Japanese beetles later in the year. For more information on this pest including control options, visit http://ecoipm.com/ and Ornamentals and Turf Insect Note ENT/ort-31 at http://www.ces.ncsu.edu/depts/ent/notes/O&T/shrubs/note31/note31.html.
