Antifeedant and sublethal effects of imidacloprid on Asian citrus psyllid, Diaphorina citri

Abstract

Sublethal concentrations of imidacloprid negatively affect development, reproduction, survival and longevity of ACP, which likely contributes to population reductions over time. Also, reduced feeding by ACP adults on plants treated with sublethal concentrations of imidacloprid may potentially decrease the capacity of ACP to successfully acquire and transmit the HLB causal pathogen.

Susceptibility of Asian citrus psyllid, Diaphorina citri (Hemiptera: Liviidae), to the insecticide afidopyropen: a new and potent modulator of insect transient receptor potential channels

“…In a similar investigation, cyantraniliprole reduced the oviposition, nymph development, and adult emergence of D. citri at 0.25 AI ng/μL (Tiwari and Stelinski 2013). D. citri maintained on plants treated with an aqueous solution of imidacloprid (0.1 AI ng/μL) exhibited reduced fertility, fecundity, and nymph survival as compared with controls (Boina et al 2009). Sublethal effects on D. citri have also been observed with pyriproxyfen, buprofezin, and diflubenzuron, which caused reduced development of eggs, nymphs, and adults (Boina et al 2010;Tiwari et al 2012).…”

“…A leaf dip bioassay as described in Boina et al (2009, and Prabhaker and Toscano (2007) was also used to evaluate the activity of afidopyropen against D. citri adults. Finally, an additional comparison was made with a topical application technique described in .…”

Differential Efficacy of Insecticides According to Crop Growth: The Citrus Psyllid on Citrus Plants

“…Although either imidacloprid or methidathion was not effective if they were applied on grown trees in field (Ichinose et al, 2010b), it has been reported that imidacloprid effectively control psyllid populations in field (cf. Srninivasan et al, 2008;Boina et al, 2009;Gatineau et al, 2010). Thus, the application of imidacloprid and methidathion in field was examined also in this study.…”

“…Many studies have been performed to examine the efficacy of various insecticides on the control of psyllids, revealing that neonicotinoids such as imidacloprid or thiamethoxam are very effective on the psyllid (Hayashikawa et al, 2006;Yasuda et al, 2006;Srinivasan et al, 2008;Gatineau et al, 2010;Ichinose et al, 2010a). These insecticides are characterised by their long-continued residue effect on the pest, up to several months (Yasuda et al, 2007), and their reducible effects on the psyllid population can continue even after the concentration of the insecticides is decreased below the lethal level (Boina et al, 2009). Important issues in the use of insecticides are 1) how frequently an insecticide should be applied in year, 2) how much the insecticide should be used in each application, and 3) when the insecticide application should be performed in the year.…”

The invertebrate pharmacology of insecticides acting at nicotinic acetylcholine receptors

“…These parameters combined with bioavailability, concentration, distribution and biotransformation (production of active/inactive metabolites) determine delivery of the ultimate pathophysiological effects -anti-feedency and neurotoxicity. 94,95) 2.1.4. Acetamiprid and thiacloprid Acetamiprid and thiacloprid possess a cyanoamidine pharmacophore.…”
