Source webinar: Cockroaches, Dr. Dan Suiter, November 10, 2021
Series: Structural Pest Control
Duration: 54:51
CEU Categories: [PENDING: awaiting team confirmation]
Exercises: 3 (8 pairs each, 2 distractors each)
Scope note. Every term, description and distractor comes from this recording. Each Column B list carries two extra items that Suiter did in fact describe, but that match none of the items in Column A, so students cannot work the exercise by elimination.
Exercises
Matching Exercise 1: Cockroach Species and Life Stages
Timestamp Reference: 8:50 – 41:36 (primary coverage area)
Type: Species ID
Instructions: Match each item in Column A with the correct description in Column B. Two items in Column B do not match anything in Column A.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | Eurycotis floridana | a) Originally from Africa, and lives three months on water alone | |
| 2 | Smoky brown cockroach | b) Wings on the male cover about two-thirds of the abdomen; the female is wingless | |
| 3 | American cockroach | c) Stings a cockroach egg capsule and lays about 80 eggs inside it | |
| 4 | Periplaneta brunnea | d) Wingless, heavy, lives in palm trees, and sprays a pungent defensive compound | |
| 5 | Oriental cockroach | e) Three quarters of an inch long, and lives more than a month on water alone | |
| 6 | Turkestan cockroach | f) Originally from Japan, and the most common large roach in Georgia | |
| 7 | German cockroach | g) White band behind the head, white antennal tips, about an eighth of an inch long | |
| 8 | First instar smoky brown | h) Known mainly from the southwestern United States, turned up in Griffin, and outcompetes the Oriental | |
| i) The first thing to arrive on dead insects lying outdoors in the South | |||
| j) Similar to the American roach, but with slightly different biology |
Answer Key:
1 → d, 2 → f, 3 → a, 4 → j, 5 → b, 6 → h, 7 → e, 8 → g
Distractors: c) is the parasitoid wasp that attacks egg capsules (27:03 – 28:12). i) is the fire ant (45:19 – 45:52). Neither is a cockroach.

Matching Exercise 2: Products, Active Ingredients, and Uses
Timestamp Reference: 17:54 – 46:05 (primary coverage area)
Type: Product-Ingredient
Instructions: Match each item in Column A with the correct description in Column B. Two items in Column B do not match anything in Column A.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | Killmaster | a) Granular scatter baits Suiter named for the large roaches | |
| 2 | Allopurinol | b) Poured onto white bread as the attractant in the paint can trap | |
| 3 | Oxypurinol | c) A Dursban paint, white and almost a paste, brushed around the inside edge of a manhole cover | |
| 4 | Indoxacarb | d) A human gout drug fed to cockroaches; the University of Florida patented the use | |
| 5 | Niban and Advion IG | e) Sold as a blue paste applied with a knife, and eaten readily by the large roaches | |
| 6 | Pyrethroid microcap | f) Still active inside the dead cockroach, which turns the body into a fire ant bait | |
| 7 | Advion gel | g) Mixed one to one and used to coat the inside lip of a paint can | |
| 8 | Mineral oil and Vaseline | h) The active ingredient in a commercialized bait that worked at growth regulator speed | |
| i) Put out in a local park trial before the label came through; roaches fed on it that night | |||
| j) Works on a wall or a tree hole, and kills the egg case parasitoids along with the roaches |
Answer Key:
1 → c, 2 → d, 3 → h, 4 → f, 5 → a, 6 → j, 7 → i, 8 → g
Distractors: b) is the cheap beer used in the trap (43:07 – 43:21). e) is the boric acid paste bait Suiter recalled from the era of tub formulations (38:46 – 38:58); he named two products on air and neither name is reproduced here, since the audio is unresolved. Neither item matches a Column A entry.
