“…Nutrient contents in potato leaves vary along with plant and leaf physiology (Hare, 1983;Domek et al, 1995), which results in changes of the phloem-sap composition from a predominantly carbohydrate content in younger leaves to greater quantities of amino-nitrogen compounds in the older senescent ones (Thomas & Stoddart, 1980). It has been shown that the population dynamics of the peach-potato aphid are associated with potato physiology, the growth rate being greater on older leaves than on younger foliage (Bradley, 1952;Shands et al, 1954;Taylor, 1955Taylor, , 1962Mack & Smilowitz, 1981;Jansson & Smilowitz, 1985).…”

Transgenesis developed in the last 20 years offers new possibilities for crop protection. The transgenic process, however, requires the use of marker fusion genes to select and visualize the transformed tissues. Although the expression products of these marker genes are stably expressed in crops, little attention has been given to assess the eventual risks of these recombinant proteins on phytophage populations. Three independent transgenic potato ( Solanum tuberosum ) clones from the cultivar Désirée (DG5, DG18, and DG20) carrying the commonly used nptII-gus gene construct and exhibiting different β -glucuronidase activity (0.843 ± 0.011, 0.576 ± 0.096, and 0.002 ± 0.000 pmol min − 1 .mg − 1 , respectively) were evaluated to determine the impact of the encoded proteins on the behaviour, development, reproduction, and demography of the peach-potato aphid, Myzus persicae , under laboratory-controlled light and temperature. Our results revealed that the transgenic event can alter aphid physiology or behaviour. Experiments showed a probiotic effect of one transgenic line, the DG5, resulting in reduced prereproductive period and mortality, and enhanced daily fecundity, which was expressed in a greater population growth potential (r m = 0.205 vs. r m = 0.174 of the control). In contrast, aphids fed with the DG18 line exhibited reduced adult survival and reproductive period but no alteration of their demographic parameters (r m = 0.176). Finally, no physiological alteration was induced in aphids fed on a DG20 diet (r m = 0.170). Behavioural experiments conducted in a 4-choice olfactometer demonstrated that insects were significantly more attracted by the odour of transgenic DG18 potato plant than that of Désirée non-transformed plant, spending twice as much time in the DG18 plant odour. The two other transformed clones (DG5 and DG20) were as attractive as the non-transformed cultivar. It is concluded that the β -glucuronidase expression in potato plants might be responsible for the probiotic effect measured on the feeding aphids, whereas alteration of the foliage odour would result from a pleiotropic effect.

“…Important outbreaks of potato intoxications in humans have occurred in several areas of the world in the 1900s, with most victims only mildly affected (Lee 2006a). The concern about the toxicity potential of potatoes extends to the ingestion of the foliage and stems because of the economic desire to make use of this potential forage, which has reasonable crude protein for livestock (15 -18% in young plants of the Kennebec variety), and because of the consumption of potato greens by certain ethnic groups (Domek et al 1995;Phillips et al 1996). However, young dairy cattle experimentally fed 6.8 -13.6 kg sprouted potatoes or 0.9 -2.7 kg of sprouts daily for 6 -7 weeks failed to develop adverse effects (Dice 1931).…”

“…O autor constatou que os adultos mostraram preferência para se alimentar em folhas mais novas desta planta, o que resultou também em maior fecundidade. Folhas senescentes foram também menos preferidas pelos adultos.Folhagem de batata com três idades fisiológicas diferentes ( < 3 dias, 5 a 7 dias e 15 a 21 dias de idade), foram analisadas porDomek et al (1995) visando desenvolver uma dieta sintética para criação do crisomelídeo Leptinotarsa decemlineata (Say). A concentração de aminoácidos e o conteúdo de proteína foram maiores nas folhas mais novas em relação às mais velhas, enquanto que as concentrações de amido e de minerais foram maiores em folhas mais velhas.…”
