2001 journal article

An adaptive benefit of facultative coprophagy in the German cockroach Blattella germanica

ECOLOGICAL ENTOMOLOGY, 26(2), 154–162.

By: R. Kopanic n, G. Holbrook n, V. Sevala n & C. Schal n

author keywords: Blattella germanica; cockroach; coprophagy; nutrient flow; survival analysis
TL;DR: A possible adaptive benefit of coprophagy was investigated in nymphs of the German cockroach Blattella germanica (L.) and it was found thatCoprophagy is an important regulator of immunity in cockroaches. (via Semantic Scholar)

2001 journal article

Attractiveness of insecticide baits for cockroach control (Dictyoptera : Blattellidae): Laboratory and field studies

JOURNAL OF ECONOMIC ENTOMOLOGY, 94(3), 686–693.

By: G. Nalyanya n, D. Liang n, R. Kopanic n & C. Schal n 

author keywords: Blattella germanica; Supella longipalpa; baits; cockroach; attractants
MeSH headings : Animals; Blattellidae / drug effects; Blattellidae / physiology; Female; Insecticides / pharmacology; Laboratories; Male; Pest Control, Biological / methods; Pheromones / pharmacology
TL;DR: It is demonstrated that attractiveness of bait can be dramatically affected by the age of the bait, and that the formulation of bait stations may be critical for retention of attractiveness of baits. (via Semantic Scholar)

2001 journal article

Transfer of ingested insecticides among cockroaches: Effects of active ingredient, bait formulation, and assay procedures

JOURNAL OF ECONOMIC ENTOMOLOGY, 94(5), 1229–1236.

By: G. Buczkowski n, R. Kopanic* & C. Schal* 

author keywords: Blattella germanica; coprophagy; horizontal toxicant transfer; bait
MeSH headings : Animals; Biological Assay / methods; Blattellidae / metabolism; Boric Acids / metabolism; Chlorpyrifos / metabolism; Insect Control / methods; Insecticides / metabolism; Ivermectin / analogs & derivatives; Ivermectin / metabolism; Male; Pesticide Residues; Pheromones / metabolism; Pyrazoles / metabolism; Pyrimidinones / metabolism
TL;DR: In the absence of cannibalism and necrophagy, translocation of baits and secondary kill are most effective with slow acting insecticides in palatable baits that can traverse the digestive tract and be deposited within and around the cockroach aggregation. (via Semantic Scholar)

1999 journal article

Coprophagy facilitates horizontal transmission of bait among cockroaches (Dictyoptera : Blattellidae)

ENVIRONMENTAL ENTOMOLOGY, 28(3), 431–438.

By: R. Kopanic n & C. Schal n 

author keywords: Blattella germanica; coprophagy; horizontal toxicant transfer; bait
TL;DR: It is concluded that aggregating 1st instars are relatively sedentary, and that they depend on conspecific foragers to deliver widely dispersed food, thus facilitating forager-mediated translocation and delivery of slow- acting bait insecticides to inaccessible cockroach aggregations.

1998 journal article

Field and laboratory evaluation of female sex pheromone for detection, monitoring, and management of brownbanded cockroaches (Dictyoptera : Blattellidae)

JOURNAL OF ECONOMIC ENTOMOLOGY, 91(2), 480–485.

By: D. Liang, A. Zhang, R. Kopanic*, W. Roelofs & C. Schal 

author keywords: Supella longipalpa; supellapyrone; sex pheromone; trapping; pest detection; monitoring
TL;DR: The synthetic sex pheromone of the female brown banded cockroach, Supella longipalpa (F), was highly attractive to males in the field and offers a powerful monitoring and pest management tool. (via Semantic Scholar)

1997 journal article

Relative significance of direct ingestion and adult-mediated translocation of bait to German cockroach (Dictyoptera: Blattellidae) nymphs

JOURNAL OF ECONOMIC ENTOMOLOGY, 90(5), 1073–1079.

By: R. Kopanic n & C. Schal n 

author keywords: Blattella germanica; coprophagy; horizontal toxicant transfer; bait
TL;DR: It is concluded that horizontal toxicant transfer is a key factor in suppression of cockroach pest populations, especially 1st instars, which forage infrequently and are least vulnerable to direct contact with insecticides, are most susceptible to this type of insecticide translocation.
