Comparative Efficacy of Residual Insecticides against the Turkestan Cockroach, Blatta lateralis, (Blattodea: Blattidae) on Different Substrates

Abstract

The Turkestan cockroach, Blatta lateralis (Walker) is an invasive urban pest prevalent throughout the Southwestern United States. Despite the presence of this cockroach in peridomestic areas, there is limited information on strategies that can be utilized by pest management professionals (PMPs) to effectively manage populations of this pest. We evaluated the efficacy of dry residues of liquid insecticides commonly used for household and structural insect pest control: Tandem (0.10% thiamethoxam, 0.03% lambda-cyhalothrin), Transport GHP (0.05% acetamiprid, 0.06% bifenthrin), Temprid SC (0.10% imidacloprid, 0.05% beta-cyfluthrin), Demand CS (0.06% lambda-cyhalothrin), Talstar P (0.06% bifenthrin), and Phantom (0.5% chlorfenapyr) on three different substrates against Turkestan cockroach nymphs. Except for Phantom and Talstar P, all insecticide formulations killed 100% of the cockroaches on concrete, 89–100% on tile, and 77–100% on wood within 4 days. The rate of cockroach mortality varied according to the substrates to which they were exposed. Temprid SC and Transport GHP killed cockroaches faster on tile than wood. Tandem provided a faster mortality rate than Transport GHP and Temprid SC on concrete. Demand CS and Tandem killed cockroaches at similar rates on the three substrates. This study provides information to guide PMPs in their selection of insecticide formulations for the management of Turkestan cockroach infestations.

Measured efficacy, bioaccumulation, and leaching of a transfluthrin‐based insecticidal paint: a case study with a nuisance, nonbiting aquatic insect

“…Outdoor pyrethroid applications are subject to a range of physical surface conditions and environmental variables that govern their efficacy, persistence, and mobility. [50][51][52][53] Here, we demonstrate the impact of UV exposure and substrate texture on the long-term efficacy of a TFL paint formulation. Variability in insect responses among treatments were not apparent until 240 days after the initial application.…”

“…Wash‐off potential is a complex process. Critical factors that influence the off‐site transport of pyrethroids post‐application ( e.g ., time‐based precipitation intensity, cumulative rainfall post‐application, time between irrigation or precipitation events) are rigorously modeled for the urban environment in California 53 . Several studies have documented their prevalence and distribution in aquatic habitats adjacent to urban development 22,23,66 .…”

A Review of Alternative Management Tactics Employed for the Control of Various Cockroach Species (Order: Blattodea) in the USA

“…Several tools and strategies have been recently proposed for management of infestations of Turkestan cockroaches. Recently, laboratory studies showed that most of the liquid insecticides labeled for peridomestic cockroaches are highly effective against Turkestan cockroach nymphs when applied as residues to common harborage materi-als [144]. Since most of the effective insecticide formulations against Turkestan cockroaches contain pyrethroids, a known repellent chemical class [145], liquid sprays could be applied to potential harborage areas to "cockroach proof" them.…”

Potential use of synthetic and natural aromatic mixtures in prevention from Shelfordella lateralis сockroaches

“…Pesticides are currently routinely utilized to control synanthropic insects such as cockroaches. This method is both efficient and cost-effective (Gaire & Romero, 2020). On the other hand, pesticides pose a substantial toxicological threat to people when abused or overused (Mille & Peters, 2004;DeVries et al, 2019).…”
