ABSTRACT.
lant domestication by selective breeding may reduce plant chemical defense in favor of growth. However, few studies have simultaneously studied the defensive chemistry of cultivated plants and their wild congeners in connection to herbivore susceptibility. We compared the constitutive glycoalkaloids (GAs) of cultivated potato, Solanum tuberosum, and a wild congener, S. commersonii, by liquid chromatography coupled to mass spectrometry. We also determined the major herbivores present on the two species in field plots, and tested their preference for the plants and their isolated GAs in two-choice bioassays. Solanum commersonii
had a different GA profile and higher concentrations than S. tuberosum. In the field, S. tuberosum was mostly attacked by the generalist aphids Myzus persicae and Macrosiphum euphorbiae, and by the specialist flea beetle Epitrix argentinensis. In contrast, the most common herbivore on S. commersonii was the specialist sawfly Tequus sp. Defoliation levels were higher on the wild species, probably due to the chewing feeding behavior of Tequus sp. As seen in the field, M. persicae and E. argentinensis preferred leaf disks of the cultivated plant, while Tequus sp. preferred those of the wild one. Congruently, GAs from S. commersonii were
avoided by M. persicae and preferred by Tequus sp. The potato aphid performed well on both species and was not deterred by S. commersonii GAs. These observations suggest that different GA profiles explain the feeding preferences of the different herbivores, and that domestication has altered the defensive capacity of S. tuberosum. However, the wild relative is still subject to severe defoliation by a specialist herbivore that may cue on the GAs.

RESUMO
A lagarta-das-fruteiras Argyrotaenia sphaleropa (Meyrick) tem causado prejuízos significativos em frutíferas cultivadas no Sul do Brasil com destaque para o caquizeiro, pessegueiro e videira. Neste trabalho, apresenta-se a resposta de machos de A. sphaleropa a diferentes formulações e doses do feromônio sexual sintético e a longevidade das formulações mais eficientes no campo. As formulações contendo Z11,13-14Ac + Z11,13-14Al + Z11-14Al (4:4:1), Z11,13-14Al + Z11,13-14Ac (9:1) e Z11,13-14Ac + Z11,13-14Al (9:1) (1,0 mg/septo) foram as mais eficientes na captura de machos quando comparadas com fêmeas virgens. A dose de 1,0 mg/septo foi significativamente superior a 0,1 mg na captura de A. sphaleropa para as três formulações. A formulação Z11,13-14Ac + Z11,13-14Al + Z11-14Al (4:4:1), na dose de 1,0 mg/septo, foi eficiente por pelo menos 75 dias, enquanto que a Z11,13-14Ac + Z11,13-14Al (9:1) por até 60 dias. Para futuros trabalhos visando o monitoramento de A. sphaleropa com feromônio sexual na cultura do caquizeiro, recomenda-se o emprego das formulações Z11,13-14Ac + Z11,13-14Al + Z11-14Al (4:4:1) na dose de 1,0 mg/septo, substituindo os septos de borracha a cada 75 dias.
ABSTRACT
Argyrotaenia sphaleropa (Meyrick) has been leading to significative damage in cultivated fruits such as persimmon, peach and grape in Southern Brazil. In the present work, the response of A. sphaleropa males to different formulations and doses of the synthetic sexual pheromone was evaluated, as well as the duration of the most efficient formulations under field conditions. Formulations containing Z11,13-14Ac + Z11,13-14Al + Z11-14Al (4:4:1), Z11,13-14Al + Z11,13-14Ac (9: 1) and Z11,13-14Ac + Z11,13-14Al (9: 1) (1.0 mg/ dispenser) were the most efficient as male attractants when compared to unmated females. The concentration of 1.0 mg/ dispenser was significantly more attractive than the 0.1 mg/ dispenser for the three formulations. The formulation Z11,13-14Ac + Z11,13-14Al + Z11-14Al (4:4:1), at 1.0 mg/dispenser, was efficient for at least 75 days, while the attractiveness of Z11,13-14Ac + Z11,13-14Al (9:1) lasted 60 days. Further field
experiments should employ the formulation Z11,13-14Ac + Z11,13-14Al + Z11-14Al (4:4:1) at 1.0 mg/dispenser, being dispensers replaced at 75-days intervals. MenosRESUMO
