“…Os danos causados por esta mosca em videira estão relacionados à queda de bagas (Zart et al, 2011) e, também, ao transporte e à inoculação de patógenos como Cladosporium spp., Botrytis cinerea Pers., Colletotrichum spp. e Penicillium spp., que são favorecidos por puncturas para oviposição feitas pela mosca-das-frutas sul-americana (Machota Junior et al, 2013). Assim, é importante, também, saber se os danos causados pela mosca-das-frutas sul-americana, durante a oviposição, pode favorecer a infestação pela D. suzukii.…”

Resumo -O objetivo deste trabalho foi avaliar a suscetibilidade de genótipos de videira à drosófila-da-asamanchada, Drosophila suzukii (Diptera: Drosophilidae), em bagas de uva intactas e em bagas infestadas após a ocorrência de puncturas, causadas pela oviposição da mosca-das-frutas sul-americana [Anastrepha fraterculus (Diptera: Tephritidae)] ou por danos mecânicos (alfinetes). Os experimentos foram realizados em laboratório, a 22±1°C, umidade relativa de 65±10% e fotófase de 12 horas. A suscetibilidade foi avaliada para 18 genótipos de videira, em bagas intactas submetidas às fêmeas de D. suzukii. O potencial de interação foi verificado em bagas de uva 'Italia', cuja epiderme foi danificada por puncturas de A. fraterculus ou por alfinete, em comparação a frutos de morango 'Albion'. As cultivares de Vitis labrusca 'Niagara Rosada' e 'Concord' não foram infestadas por D. suzukii, e cinco dos oito genótipos que foram infestados são cultivares melhoradas. A infestação de D. suzukii em bagas de uva 'Italia' com danos mecânicos, feitos com um alfinete ou pela oviposição de A. fraterculus, foi semelhante à de bagas íntegras. Há baixa adequação hospedeira de videiras a D. suzukii, mesmo com a presença de danos. As cultivares 'Benitaka', 'BRS Vitória' e 'BRS Morena' são as mais suscetíveis a D. suzukii.Termos para indexação: Anastrepha fraterculus, Vitis labrusca, Vitis vinifera, drosófila-da-asa-manchada, mosca-das-frutas. Susceptibility of grape vine genotypes by the infestation of Drosophila suzukii (Diptera: Drosophilidae)Abstract -The objective of this work was to evaluate the susceptibility of vine genotypes to the spotted wing drosophila, Drosophila suzukii (Diptera: Drosophilidae), on uninjured grapes and on infested grapes after the occurrence of puncture sites, caused either by the oviposition of South American fruit fly [Anastrepha fraterculus (Diptera: Tephritidae)] or by mechanical damage (pins). The experiments were carried out in laboratory at 22±1°C, 65±10% relative humidity, and 12-hour photophase. Susceptibility was evaluated on intact grapes of 18 genotypes subjected to D. suzukii females. The interaction potential was assessed on 'Italia' grapes, whose epidermis was damaged either by punctures caused by A. fraterculus or by pins, in comparison to 'Albion' strawberries. The 'Niagara Rosada' and 'Concord' Vitis labrusca cultivars were not infested by D. suzukii, and five out of the eight infested genotypes are improved varieties. Infestation of D. suzukii on 'Italia' grapes, with mechanical damage made by a pin or by A. fraterculus oviposition, was similar to that on undamaged grapes. There is a low suitability of host vines to D. suzukii, even with the presence of previous injuries. The 'Benitaka', 'BRS Vitória', and 'BRS Morena' vine cultivars are the most susceptible genotypes to D. suzukii.

An example of this is the work of Machota et al (2013) who examined the external body parts of adult Anastrepha fraterculus Wiedemann and showed that they contained various fungi causing rot of bunches of grapes. Most reports are concerned with special structures of the fly that house the symbionts or the presence of the pathogen within the fly midgut, which is the site of nutrient digestion and absorption into the hemolymph.…”

The objective of this work was to assess the lethal concentration and lethal time (LC and LT) of spinosad and spinetoram, combined with different food lures, and their residual effects on South American fruit fly (Anastrepha fraterculus). The toxic baits were offered in eight concentrations (2, 6, 14, 35, 84, 204, 495, and 1,200 mg L-1), combined with the following food lures: 7% sugarcane molasses, 3% Biofruit, 1.5% CeraTrap, 1.25% Flyral, 3% Samaritá Bait, and 3% Samaritá Tradicional; diluted food lures in water were used as controls. The residual effect of the formulations at 96 mg L-1 concentration were evaluated for 21 days and were compared with that of the commercial bait Success 0.02 CB. Both insecticides were toxic to adults of A. fraterculus, and mortality varied with the food lure used. The LC50and LT50ranged from 15.19 to 318.86 mg L-1and from 11.43 to 85.93 hours, respectively. Spinosad was 2 to 36 times as toxic as spinetoram when combined with different hydrolyzed proteins. Toxic baits formulated with spinosad and spinetoram (96 mg L-1) caused mortality equivalent to the one by Success 0.02 CB (90.2%), when assessed on the day of application. Toxic baits formulated with 3% Biofruit + spinosad and 3% Samaritá Bait + spinetoram are effective for managingA. fraterculusand provide up to seven days of residual effect in the absence of rain; however, only Success 0.02 CB caused more than 80% mortality for up to 21 days.
