“…Results show that spinetoram is more toxic to R. indifferens than spinosad, as measured by fly kill using the protocol here, and that all age groups of flies are similarly affected. Spinetoram is also more toxic than spinosad against many insects (Dripps et al 2008a,b; Abdel-Latif and Abdu-Allah 2011; Hamm et al 2015; Siebert et al 2016; Andreazza et al 2017), but possibly not against all (Besard et al 2011, Athanassiou and Kavallieratos 2014, Bhatta et al 2016), including fruit flies (Schutze et al 2018). For nontarget insects, whether spinetoram is more toxic than spinosad appears to depend on the insect taxa (Lefkaditis et al 2017).…”

“…Spinosad and spinetoram in soil drenches were similarly effective in preventing emergence of three tropical fruit fly species (Stark et al 2013). In a recent study, spinosad was found to be 2–36 times as toxic as spinetoram when combined with different hydrolyzed proteins against South American fruit fly Anastrepha fraterculus (Wiedemann) (Schutze et al 2018). However, as alluded to, the role of protein bait in affecting the efficacies of spinosyns is unknown.…”

Western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), is a major quarantine pest of cherries (Prunus spp.) in western North America that is often managed using the organic insecticide spinosad, but there is a question of whether its semisynthetic relative spinetoram is more toxic and better to use for controlling the fly. Here, spinosad and spinetoram effects on R. indifferens kill and oviposition were determined by exposing 3-4, 7-10, or 14-18 d old flies to dry spinosad and spinetoram (0.21 or 0.33 mg active ingredient [a.i.] per dish) and untreated cherries or to insecticide-treated cherries at 15.6, 22.5, and 29.4°C. Kill was not affected by fly age. Spinetoram killed more female flies by day 1 than spinosad at all temperatures. In both treatments, kill was lower at 15.6°C than 22.5 and 29.4°C, although a difference between 22.5 and 29.4°C was detected more often in spinosad treatments. Both insecticides killed 3-4 d old flies quickly enough to prevent oviposition, but neither prevented oviposition by 7-10 and 14-18 d old flies. Significantly, oviposition by flies exposed to spinosad and spinetoram did not differ at any temperature. Results indicate spinetoram is more toxic to R. indifferens than spinosad. However, this higher toxicity is not needed to prevent oviposition by younger flies. Furthermore, spinetoram residues are not sufficiently toxic to kill older flies quickly enough to reduce oviposition more than spinosad. Taken together, these conclusions imply that spinosad and spinetoram are equal for controlling R. indifferens infestations.

Toxic bait is an alternative to manage fruit flies (Tephritidae) in orchards and in wide-area programmes. The mortality caused by different dilutions of spinosad baits on adults of Ceratitis capitata (Wied.) and Anastrepha grandis (Macquart) (Tephritidae) were compared with a hydrolysed protein (BioAnastrepha) and water in laboratory. Females and males of C. capitata and A. grandis were exposed to Success® 0.02CB (GF-120 NF Naturalyte fruit-fly, 0.02% spinosad) diluted in distilled water (v/v) at 1:1.5; 1:4.5; 1:9.0 and 1:18.0. Spinosad dilutions at 1: 1.5 and 1: 4.5 showed similar effects and provided 100% adult mortality 24 hours after exposure to the baits. Anastrepha grandis was more susceptible to spinosad baits than C. capitata. Females of C. capitata were less susceptible to spinosad diluted at 1: 1.5, 1: 4.5 and 1: 90, than C. capitata males and both sexes of A. grandis. The values of lethal times (LT50) varied for the different dilutions of spinosad for both fruit-fly species; however, with different patterns for each species. The LT50 values of the two highest concentrations (1: 1.5, 1: 4.5) of spinosad bait were similar for fruit flies of both sexes of each species, but a significant difference was observed between species, with higher LT50 values for C. capitata. In general, the cumulative mortalities of spinosad baits increased at 240, 360, 480 minutes and 24 hours after exposure. BioAnastrepha was shown to be toxic to both species, especially for A. grandis, killing 82% of females and 72% of males at 24 hours after exposure. Spinosad bait may be used in different dilutions to manage C. capitata and A. grandis, with similar toxicity for the two highest spinosad concentrations.

“…Spinosyns (spinosad and spinetoram), neurotoxic insecticide agonists of acetylcholine, have received attention because they are more selective to beneficial insects, when compared to organophosphates (Crouse et al 2001, Sparks et al 2001, Galm & Sparks 2015, Schutze et al 2018, and have, therefore, become alternatives for the management of the Mediterranean fruit fly. Spinosad is a naturally occurring metabolite that is formed through the anaerobic fermentation of the Saccharopolyspora spinosa Mertz & Yao bacterium, and is composed of two microcyclic lactones, spinosyn A and spinosyn D. This metabolite is the lethal agent employed in the commercial toxic bait Success ® 0.02 CB (Hsu & Feng 2006, Akmoutsou et al 2011, Markussen & Kristensen 2011, Vontas et al 2011, Galm & Sparks 2015.…”

The use of toxic baits with spinosyns (spinosad and spinetoram), along with the parasitoid Diachasmimorpha longicaudata, is a sustainable alternative for the management of Ceratitis capitata. This study aimed to evaluate the lethal concentration (LC) and lethal time (LT) of spinosad and spinetoram, associated with the food lures sugarcane molasses at 7 %, Biofruit at 3 %, Ceratrap® at 1.5 %, Flyral® at 1.25 %, Isca Samaritá® and Samaritá Tradicional® at 3 %, on C. capitata, under laboratory conditions, as well as their effect, at the concentration of 96 mg L-1, on D. longicaudata. For the lethal time data, mortality was assessed at 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 36, 48, 60, 72, 84 and 96 h after the exposure to the toxic baits. The lowest lethal concentrations (LC50 and LC95), to spinetoram (0.5 mg L-1 and 3.7 mg L-1, respectively) and spinosad (0.8 mg L-1 and 7.8 mg L-1, respectively), corresponded to the association with Samaritá Tradicional® at 3 %. The lowest lethal time (TL50), in hours, for the spinosad insecticide, corresponded to the formulation containing Biofruit at 3 % (6.6), and, to spinetoram, Samaritá Tradicional® at 3 % (7.9). For D. longicaudata, the formulations that caused the lowest mortality corresponded to the association of Biofruit® at 3 % with spinosad (4.7 %) and Samaritá Tradicional® at 3 % with espinetoram (3.5 %). The toxic baits formulated with spinosad and espinetoram, associated with Isca Samaritá® at 3 %, caused a mortality rate of more than 60 % to the parasitoid D. longicaudata.
