“…Such high levels of resistance to these insecticides, which have similar modes of action, could be caused by long‐term selection with residual pyrethroid insecticides. The observed resistance to fipronil (∼37‐fold) could be attributed to previous selection by older fipronil‐containing gel baits or cross‐resistance conferred by earlier cyclodiene selection 9, 33–35…”

A two-tiered susceptibility monitoring strategy was developed that includes testing field populations at diagnostic concentrations and doses in first-tier vial LC bioassays and second-tier gel bait matrix LD bioassays. The vial method facilitates rapid identification of field strains with reduced susceptibility. The feeding bioassay effectively simulates field exposure to Advion(®) and therefore has utility for secondary confirmation of susceptibility shifts and identification of behavioral resistance (i.e. bait aversion).

“…German cockroaches are resistant to all major groups of insecticides ( Cornwell 1976; Cochran 1995). Most reports of B. germanica resistance involved dose–response bioassays ( Bennett & Spink 1968; Batth 1977; Rust & Reierson 1991; Zhai & Robinson 1991), but do not detail underlying resistance mechanisms.…”

The possible insecticide resistance mechanisms of four Malaysian field-collected strains of the German cockroach, Blattella germanica (Linnaeus) (Dictyoptera: Blattellidae), were characterized with biochemical assays and native polyacrylamide gel electrophoresis (PAGE). Elevated esterase activity (at low to moderate frequency) and altered acetylcholinesterase (low frequency) were detected in all field strains, while elevated glutathione S-transferase levels were present in only two strains. Seven esterase bands were separated by native PAGE; a greater intensity occurred in three bands in the resistant strains compared to the susceptible strain. Inhibition studies using specific inhibitors on polyacrylamide gels suggested that the slowest of these three esterases is a cholinesterase, while the other two are carboxylesterases with a preference for beta- over alpha-naphthyl acetate.

“…Historically, German cockroaches have been able to develop extensive resistance to different insecticides (Cochran 1995). Insecticide resistance in laboratory and field-collected German cockroaches has been reported for decades (Bennett and Spink 1968; Koehler and Patterson 1986; Cochran 1987; Umeda et al 1988; Cochran 1989; Hemingway et al 1993a, 1993b; Valles and Yu 1996; Lee et al 1996; Scharf et al 1997; Scharf et al 1998; Wei et al 2001; Holbrook et al 2003; Gondhalekar et al 2011, 2013; Ko et al 2016a; Naqqash et al 2016). In total, German cockroaches have shown resistance to 43 active ingredients (AIs) (Whalon et al 2016), and therefore, resistance management has become a priority in any cockroach IPM program.…”

Insecticide resistance in German cockroaches (Blattella germanica (L.)) has been a barrier to effective control since its first documentation in the 1950s. A necessary first step toward managing resistance is to understand insecticide susceptibility profiles in field-collected strains so that active ingredients (AIs) with lowest resistance levels can be identified. As a first step in this study, diagnostic concentrations (DCs) were determined for 14 insecticide AIs based on lethal concentrations that killed 99% or 90% of the individuals from a susceptible lab strain (JWax-S). Next, cockroaches were collected from two low-income multifamily housing complexes in Danville, IL, and Indianapolis, IN, and used to establish laboratory strains. These strains were screened against the 14 AI-DCs in vial bioassays, and susceptibility profiles were determined by comparing percent mortalities between the field strains relative to the JWax-S strain. Results revealed lowest resistance of field strains to boric acid, abamectin, dinotefuran, clothianidin, thiamethoxam, and chlorfenapyr. For the AIs hydramethylnon and imidacloprid, field strains did not display survivorship different than the lab strain, but >90% mortality was never achieved. Lastly, both field strains displayed resistance to indoxacarb, fipronil, acetamiprid, beta-cyfluthrin, bifenthrin, and lambda-cyhalothrin, but at varying levels. These results satisfy two objectives. First, baseline monitoring DCs were established for 14 insecticides presently registered for use against cockroaches, which represents a useful resource. Second, our findings reveal insecticide AIs with lowest resistance levels for use in forthcoming field studies that will investigate impacts of different insecticide deployment strategies on resistance management and evolution in cockroach field populations.
