Commercial Applicator Recertification Training Changes for 2020

–by Frannie Miller

Each year in the fall, I plan trainings and look forward to seeing applicators from across the state as they attend these commercial recertification training programs. This year will look a lot different in terms of training opportunities. Due to the ever presence of Covid, the Kansas State Pesticide Safety Program will be hosting virtual training opportunities through zoom. This will allow the applicator to obtain pest management credits from the safety of his or her home or office. I have heard from some applicators that feel they are technologically challenged, but don’t let that keep you from trying a new way of learning. The team is here to help you every step of the way!

The Kansas State Pesticide Safety Program is hosting training on the following dates:

  • October 20 – 21 (9:20 a.m. – 11:30 a.m.) (1:20 p.m. -3:30 p.m.) Right-of-Way, Industrial Weed, and Noxious Weed Training (Category 6, 7C, & 9A)
  • November 2 (12:30 p.m. – 5:15 p.m.) and November 3 (8:30 a.m. – 11:30 a.m. Stored Product Pests and Seed Treatment (Category 7B & 4)
  • November 4 (9:20 a.m. – 11:30 a.m.) Ornamental, Turf and Interiorscape (Category 3A, 3B, & 3C)
  • November 9 (8:30 a.m. – 5:00 p.m.) Ag Plant (Category 1A)
  • November 10 (8:30 a.m. – 5:00 p.m.) Structural and Public Health (Category 7D, 7E & 8)
  • November 10 (12:00 p.m. – 1:00 p.m.) Core Hour
  • November 12 (8:30 a.m. – 5:00 p.m.) Wood Destroying and Wood Preservation (Category 7A & 7F)
  • November 12 (12:00 p.m. – 1:00 p.m.) Core Hour
  • November 13 (8:30 a.m. – 5:00 p.m.) Forest Pest, Ornamental, Turf and Interiorscape (Category 2, 3A, 3B & 3C)

ID to last week’s bug

–by Frannie Miller

Tiger Beetle: This Punctured Tiger beetle is attracted to ultraviolet light, so I was able to capture this image under the lights of a tennis match. This species tends to be dull colored with a few small spots. Tiger beetles tend to be extremely quick in their movements making it challenging to get pictures. The feeding habits of the adult and larvae stage make them somewhat beneficial.

Soldier Beetles

–by Dr. Jeff Whitworth

Have had several inquiries regarding soldier beetles (please see fig 3 provided by Kaysie Morris). These beetles are quite common throughout Kansas and most commonly noticed in late summer as the adults are highly mobile, relatively large, and are very active searching for and feeding on pollen. Thus, they can be very common on any crop, or weed, that is pollinating, especially sunflowers, sorghum, and cucurbits such as cantaloupes and watermelons. Soldier beetles are often mistaken for blister beetles because of their size and shape but are not in the same taxonomic family and thus, produce no cantharidin, the chemical that causes external blisters in humans and other problems in livestock when ingested. However, soldier beetles are harmless.

Green Cloverworms

–Dr. Jeff Whitworth

Green cloverworms are still feeding on soybean leaves, and therefore still causing some concern, especially in double-cropped soybeans (some fields were being treated with insecticides on 2 Sep). As stated previously, green cloverworms can be very voracious leaf feeders. However, rarely, if ever, do they cause enough damage especially at this time of year (and plant developmental stage) to justify an insecticide application. Plus the soybean canopy usually harbors many different types of beneficials and they will be negatively affected by an insecticide application. Green cloverworms also seem to be very vulnerable to natural controls (please see figs 1 & 2, of fungus-infected green cloverworm larvae, provided by Mr. Tom Maxwell), which often effect great control on green cloverworm populations.

Golden Garden Spider

–by Dr. Raymond Cloyd

This is the time of year when we see the golden garden spider, Argiope aurantia, in landscapes, gardens, and in unmanaged areas. Golden garden spiders are 1.0 inch (25.4 mm) long, with black and yellow markings on the abdomen, and a silvery cephalothorax (combination of head and thorax) (Figure 1). The spider typically hangs with the head positioned downward in the center of a web that has vertical crossed zigzag bands (Figure 2).

Figure 2. Golden garden spider in web. Note the vertical zigzag bands in the web (Raymond Cloyd, KSU)

Golden garden spiders find prey in their webs by sensing vibrations as prey try to escape. Spiders capture grasshoppers in their webs and then wrap them in fine silk (Figure 3). Golden garden spiders typically build webs in open areas instead of inside the canopy of trees and shrubs or inside shelters. The other species in Kansas is the banded argiope spider, Argiope trifasciata, that does not have distinct black markings on the top of the abdomen. However, thin black transverse lines may be present.
