Baseline susceptibility of Bemisia tabaci (Genn.) biotype B in southern Florida to cyantraniliprole

Cyantraniliprole: a valuable tool forFrankliniella occidentalis(Pergande) management

“…Consistently, the anticipated labelled rate of cyantraniliprole as a drench application (2.90–4.41 mg AI plant −1 ) caused no mortality to adults of either F. fusca or F. occidentalis after 3 days of exposure . Similarly, a slightly greater toxicity for nymphs than for adults has been suggested in Bemisia tabaci , but in this case the difference was lower than twofold.…”

“…The results reported from laboratory bioassays with other agricultural pests showed LC 50 values of 0.22–0.80 mg L −1 ( Myzus persicae ), 0.11–2.47 mg L −1 ( Aphis gossypii ), 0.01–0.06 mg L −1 ( Bemisia tabaci , southern Florida), 0.01–0.19 mg L −1 ( Bemisia tabaci , Arizona), 0.011–0.116 mg L −1 ( Bemisia tabaci , Mediterranean Basin) and 0.27 mg L −1 ( Diaphorina citri ) . These data suggest that, even for larvae, the LC 50 range of cyantraniliprole values in F. occidentalis is considerably higher than for many other agricultural pests.…”

An EPG Study of the Probing Behavior of Adult <I>Bemisia tabaci</I> Biotype Q (Hemiptera: Aleyrodidae) Following Exposure to Cyantraniliprole

“…In addition, cyantraniliprole is not affected by commonly occurring resistance mechanisms that are known to confer resistance to other insecticide chemistries. In laboratory tests, both biotypes B and Q showed susceptibility to cyantraniliprole on B. tabaci populations from Arizona and Florida that are resistant to imidacloprid and pyriproxyfen (Li et al 2011, Caballero et al 2013. The same results were obtained in the European strain of B. tabaci biotype Q (Bielza et al 2011).…”

“…Based on the above results, cyantraniliprole is expected to be effective within an integrated approach to virus management. Its unique mechanism of action and the absence of cross-resistance with neonicotinoids (Bielza et al 2011, Li et al 2011, Caballero et al 2013) make it a useful tool for plant protection in integrated resistance management and integrated pest management programs.…”

“…Another new insecticide active against B. tabaci with no cross-resistance to neonicotinoids is cyantraniliprole (DuPont Cyazypyr), an anthranilic diamide (Li et al 2011, Caballero et al 2013. It is a ryanodine receptor agonist, causing impairment of insect muscle function (Cordova et al 2006), that results in rapid interruption of feeding, and consequently has the potential to reduce TYLCV transmission in the Þeld (Castle et al 2009).…”
