N,N-Diethylphenylacetamide—A New Repellent for Periplaneta americana (Dictyoptera: Blattidae), Blattella germanica, and Supella longipalpa (Dictyoptera: Blattellidae)

Abstract

The residual repellency of N,N-diethylphenylacetamide (DEPA) was studied against American cockroach, Periplaneta americana (L.); German cockroach, Blattella germanica (L.); and brownbanded cockroach, Supella longipalpa (F.) at various concentrations. DEPA exhibited residual repellency for 4, 3, and 2 wk against American, German, and brownbanded cockroach, respectively, at a concentration of 0.5 mg/cm2.

Safety evaluation of various vector repellents in combination with deltamethrin in Wistar rats

“…[ 27 28 ] The other insect repellents such as Deb (used as creams and gels) and Depa are widely used across Asian regions, especially India. [ 29 30 31 ] It is a notifying feature that people living in tropical areas are very prone to mosquito-borne diseases, such as malaria, dengue, Japanese encephalitis, and filariasis. There are several studies that report the resistance developed by mosquitoes against these agents.…”

Insect repellents - past, present and future

“…Several other compounds have been evaluated for repellent activity, but none have had the commercial success of DEET. For example, N,N-diethylphenyl acetamide (DEPA) is licensed for use as a cockroach repellent in India (Prakash et al, 1990) and Colgate-Palmolive has released in Europe a cockroach repellent floor cleaner, Ajax Expel ® , the active ingredient of which is N-methyl neodecanamide. This product has been shown to cause cockroaches to leave their harborages and cockroaches are less likely to re-infest previously occupied areas after treatment with the cleaner (Brenner et al, 1998).…”

“…Therefore, new methods need to be developed in the control of cockroaches. To manage these pests, some insect repellents (plant essential oils) (Prakash et al, 1990, Paranagama & Ekanayake, 2004Yilmaz & Tunaz, 2013), diatomaceous earth application (Özcan et al, 2018;Alkan et al, 2019) and biocontrol methods are used (Fox & Bressan-Nascimento, 2006;Hernández-Ramírez et al, 2007;Maketon et al, 2010;Tee et al, 2011;Hubner-Campos et al, 2013;Gutierrez et al, 2016;Baggio-Deibler et al, 2018). Also, insecticidal paints can provide useful control of P. americana populations for up to 3 months (Bueno-Marí et al, 2013).…”
