Attractiveness of Insecticide Baits for Cockroach Control (Dictyoptera: Blattellidae) - Laboratory and Field Studies

Abstract

Several insecticide bait formulations were evaluated for their attractiveness to cockroaches in olfactometer assays in the laboratory and in trapping experiments in the field. Included in the assays were bait stations, gels, pastes, and a powder that contained one of the following active ingredients: abamectin, boric acid, chlorpyrifos, or hydramethylnon. There were significant differences among the baits in their attractiveness to the German cockroach, Blattella germanica (L.). In trapping experiments, Avert powder (abamectin), Maxforce station and gel, and Siege gel (all hydramethylnon) were consistently attractive to B. germanica adults and nymphs. Laboratory olfactometer assays with adult males confirmed these results and showed that nymphs were as responsive as males whereas females were less responsive. Our bioassays also demonstrate that attractiveness of bait can be dramatically affected by the age of the bait. One week of aging significantly reduced the attractiveness of Avert powder in both laboratory and field assays. Aging, however did not diminish the attractiveness of Maxforce gel, indicating that the formulation may be critical for retention of attractiveness of baits. Baits that were most attractive to the German cockroach were also the most attractive to nymphs and adults of the brownbanded cockroach, Supella longipalpa (F.).

Diet quality affects bait performance in German cockroaches (Dictyoptera: Blattellidae)

“…Bait efficacy is influenced by many factors, including its attractiveness and palatability, 45,46 the toxicity of different active ingredients, 14,15,45 the presence and frequency of resistance alleles within the target insect population, 44,58 -63 its ability to affect secondary mortality 12 -14 and practical considerations such as bait distribution. 64 Here we demonstrate that bait performance could also be affected by a predictable interaction between the nutritional condition of the German cockroach, which is a consequence of its nutritional history, and bait macronutrient composition.…”

Efficacy of Maxforce and Avion gel baits containing fipronil, clothianidin, and indoxacarb against the German cockroach (Blattella germanica)

“…Cockroaches were attracted to all gel baits investigated in the present study, although they were more attracted to the bait containing indoxacarb than to baits containing clothianidin and those containing 0.05% or 0.01% fipronil. Previous studies have also reported significant differences in gel bait attractiveness for German cockroaches (Durier & Rivault 2000;Nalyanya et al 2001). In the present study, mortality of German cockroaches was observed 2 h after eating gel baits, and the mortality rate increased throughout the 40-h 0.0001 0.0001 0.0001 0.0001 0.0001 0.0001 †Based on positive ranks.…”

“…for growing and mating, determine their food preference. 5,11 While wandering for food, especially in a dirty place, its body might have contact with many typr of infectious agents.

“…any places related or connected with waste water such as waste water pipe, cesspits, septic tanks, sewers, rubbish dumps, refuse tips, dustbins and cupboards, drawers, underneath chairs, tables, water-sinks, water-baths and beds, behind refrigerators, cooking stoves, among (dirty) stacked dishes and even in almost any dark place available. [1][2][3][4][5][6] all of these related to their nitrogen metabolism, and their needs of this macro-nutrient(nitrogen) and other type of micro-nutrient and other electrolyte can be fulfilled thru waste water. 17 The association of cockroaches with various enteric pathogens, especially food-borne parasite, e.g protozoan and helminths, and also with bacterial pathogens have been extensively reported, but their prevalence varied, depend on the location.…”
