Insecticide resistance in the currant–lettuce aphid, Nasonovia ribisnigri (Hemiptera: Aphididae) in the UK

Abstract

Bioassay data for a reference strain of Nasonovia ribisnigri (Mosely), exhibiting similar responses to proven susceptible strains of Myzus persicae (Sulzer) and Aphis gossypii Glover, were used to assess insecticide resistance in two suspected resistant strains and nine field strains of N. ribisnigri originating from lettuce in the UK. Results showed widespread but varied levels of resistance to pirimicarb, lower and also varied resistance to pyrethroids and organophosphates, and no significant differences in response to imidacloprid. In some strains, resistance was associated with an intensely-staining esterase band disclosed by polyacrylamide gel electrophoresis (PAGE). However, no direct relationship between esterases and resistance has yet been established. There was no biochemical evidence of an altered acetylcholinesterase contributing to pirimicarb resistance in these strains.

Inheritance of L1014F and M918T sodium channel mutations associated with pyrethroid resistance in Myzus persicae

“…(c) Determination of resistance phenotypes The pyrethroid-resistant phenotype of aphid progeny was assessed using leaf-dip bioassays with apterous adult aphids (Barber et al 1999). A single representative clone of each kdr and super-kdr genotypic combination was tested with at least six concentrations of lambda-cyhalothrin ('Hallmark', 50 g l K1 EC; Syngenta) ranging from 0.01 to 1000 ppm.…”

Paecilomyces niveus Stolk & Samson, 1971 (Ascomycota: Thermoascaceae) as a pathogen of Nasonovia ribisnigri (Mosley, 1841) (Hemiptera, Aphididae) in Brazil

“…N. ribisnigri is found throughout the lettuce head, even in the developing leaves at the center, whereas other species prefer external leaves (Liu and McCreight, 2006;Scorsetti et al, 2010). Chemical pesticides are the primary means of aphid control (Barber et al, 1999;Dedryver et al, 2010). However, N. ribisnigri is resistant to some insecticides (Martin et al, 1996;Rufingier et al, 1997;Barber et al, 1999;Dedryver et al, 2010).…”

One alternative to the use of insecticides to reduce the occurrence of this pest is integrated pest management involving the application of entomopathogenic fungi (Dorschner et al, 1991;Zaki, 1998;Steinkraus, 2006;Asman, 2007;Díaz et al, 2010;Scorsetti et al, 2010Scorsetti et al, , 2012Skinner et al, 2012).…”

Side effects of flonicamide and pymetrozine on five aphid natural enemy species

“…However, this product was particularly harmful to hoverfly larvae (Poehling and Dehne 1986;Storck-Weyhermuller 1989;Niehoff and Poehling 1995;Jansen 2000) and was therefore of limited interest for IPM where hoverflies must be preserved. In addition, several economically important aphid species, for example Aphis gossypii Glover and Myzus persicae Sulzer, have developed resistance against this insecticide (Field et al 1997;Barber et al 1999;McLoon and Herron 2009).…”
