Resumen

ELIZONDO SILVA, Ana Ibis  y  MURGUIDO MORALES, Carlos A. Spirotetramat, New Insecticide for Sucker Insects in Potato Cultivation. Fitosanidad [online]. 2010, vol.14, n.4, pp.229-234. ISSN 1818-1686.

Different insecticides are applied for the control of pests that cause damages on potato crop (Solanum tuberosum L.) during their development cycle. The consecutive use of these substances causes the appearance of secondary plagues, insect-resistance development, natural enemies destruction and affectations to the atmosphere, among other problems. For this causes is advisable the evaluation of new more efficient products for the control of the pest complex in this crop. Active ingredient spirotetramat is an insecticide that belongs to new group of cetoenols which stands out for its systemic bidirectional effect and wide action spectrum against sucker insects, as aphids, trips and white flies, among other, particularly against juvenile states. In order to evaluate the effectiveness of this insecticide in the control of Myzus persicae Sulzer, Bemisia tabaci Gennadius and Thrips palmi Karny a field experiment was developed on potato cultivation. Results indicate that the effectiveness of spirotetramat at doses of 0.5 and 0.6 L/ha were acceptable on the three plague species respect to production standard. It was found also that this new insecticide had no effect on bioregulators associated with pests, since they completed their cycles and were observed until the end of the experiment.

Palabras clave : spirotetramat; chemical control; potato; insecticides.
