“…Flonicamid acts in the aphid nervous system, disrupting the function of chrodotonal stretch receptor organs, the target site not defined as yet. Although the insecticidal properties of flonicamid (antifeedant activity) resemble those of pymetrozine, the two insecticides have different MoA (Group 29 vs. Group 9) (Morita et al ., 2007, 2014). In addition, flonicamid is a selective insecticide with null to low toxicity to beneficial arthropods (Jansen et al ., 2011; Morita et al ., 2014), and due to its antifeedant activity it can be used against aphid-transmitted plant viruses.…”

The aphid Myzus persicae s.l. (Hemiptera: Aphididae) is an important pest of many crops worldwide with a complex life cycle, intensely controlled by chemical pesticides, and has developed resistance to almost all used insecticides. In Greece, the aphid exhibits high genetic variation and adaptability and it is a classic example of evolution in the making. We have been studying M. persicae for over 20 years, on different host plants and varying geographical areas, analyzing its bio-ecology and the ability to develop resistance to insecticides. In this review, we present new and historical data on the effectiveness of insecticides from seven chemical groups used to control the aphid in Greece and the incidence of seven resistance mechanisms, including the new fast-spreading R81T point mutation of the postsynaptic nicotinic acetylcholine receptor. Thousands of samples were tested by biological, biochemical and molecular assays. The aphid populations were found to have developed and maintain resistance at medium to high levels to organophosphates, carbamates, pyrethroids and neonicotinoids for decades. In the latter group, a marked increase is recorded during an ~10-year period. The data analyzed and the extensive bibliography, advocate the difficulty to control the aphid making the design and application of IPM/IRM programs a challenge. We discuss principles and recommendations for the management of resistance, including the use of compounds such as flonicamid, spirotetramat, flupyradifurone and sulfoxaflor. We emphasize that resistance is a dynamic phenomenon, changing in time and space, requiring, therefore, continuous monitoring.

“…Additionally, flonicamid is a systemic insecticide and can be readily transported from roots to the leaves of cotton. 26,27 Third, AMF could alter rhizosphere properties, [38][39][40] then directly or indirectly affect the availability of flonicamid, and increase uptake efficiency. Some studies showed that AMF secrete organic substances to change the properties of the surrounding soil and affect the availability of nutrient.…”

“…Flonicamid is a new novel systemic insecticide with high activity against Aphis gossypii Glover and low toxicity to non-target organisms. [25][26][27] Flonicamid can inhibit the feeding behavior of aphids in less than 30 min of treatment, and the antifeeding activity is not recoverable until death 26 Our previous studies showed that flonicamid applied via drip irrigation can be absorbed by cotton roots and easily transported to leaves, resulting in effective control of cotton aphid over a prolonged period. 14 To overcome the loss of active ingredient by soil adsorption, the dosage of drip-applied flonicamid needs to be higher compared with that for a foliar spray.…”

BACKGROUND: Drip application of insecticides has been used for controlling crop pests, but the application doses are usually higher than those used for foliar spray. Arbuscular mycorrhizal fungi (AMF) have been reported to improve root absorption of nutrients from soil, which may also enhance the uptake of drip-applied insecticides, reducing application doses. In this study, greenhouse and field experiments were carried out to determine if AMF could colonize cotton roots, if the colonization could enhance the absorption of drip-applied flonicamid, and if the enhanced uptake could reduce flonicamid application dose, while maintaining control efficacy against cotton aphid. RESULTS: The applied AMF effectively colonized cotton roots and significantly promoted root growth. Fresh weights of cotton roots inoculated with multiple AMF were 28% greater than those of uninoculated plants. Multiple AMF colonization significantly increased flonicamid concentrations in leaves, which were 44.5-139.7% higher than for non AMF-colonized roots, corresponding to 3.7-31.8% increases in corrected mortalities of cotton aphid compared with uninoculated plants. AMF colonization reduced the application rate of flonicamid and the residue level of flonicamid in soil. CONCLUSION: Drip application of flonicamid to cotton roots inoculated with AMF represents a new approach to insecticide application. AMF colonization increased flonicamid uptake, improved aphid control efficacy and reduced flonicamid application rates.

“…The higher efficacy of spinosad and chlorfenapyr may be associated with their modes of action. For example, flonicamid is a selective feeding blocker (IRAC designation 29) causing starvation by inhibiting the ingestion of phloem (Cho et al, 2011;Morita et al, 2014). However, this mode of action may increase the time required to kill western flower thrips adults, especially in cut flowers.…”

The western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), is a major insect pest of greenhouse-grown horticultural crops. Western flower thrips causes direct and indirect damage by feeding on plant leaves, flowers, and fruits, and by transmitting viruses that can result in greenhouse producers experiencing substantial economic losses. Consequently, insecticides are used to suppress western flower thrips populations. However, issues associated with applying insecticides may affect the suppression of western flower thrips populations. Therefore, experiments were conducted under greenhouse conditions to determine the effects of the spray volume applied and application frequency on insecticide efficacy against western flower thrips adults located in transvaal daisy, Gerbera jamesonii, cut flowers. Four spray volumes (5.0, 10.0, 12.5, and 25.0 mL), two application frequencies (one or two spray applications), and three insecticides [spinosad (Conserve), chlorfenapyr (Pylon), and flonicamid (Aria)], each with a different mode of action, were tested. The insecticide treatments had the greatest effects on the mean percent mortality of western flower thrips adults regardless of spray volume or application frequency. However, in Expt. 3, the 5.0- and 10.0-mL spray volumes resulted in a higher mean percent mortality of western flower thrips adults than the 2.5-mL spray volume. Spinosad and chlorfenapyr resulted in a mean percent mortality of more than 72% for western flower thrips adults, whereas flonicamid resulted in mean percent mortality between 40% and 91%. Our study demonstrates that certain insecticides are more effective against western flower thrips adults located in transvaal daisy flowers than others, which will help greenhouse producers effectively manage western flower thrips populations.
