Finally, one important aspect of IRM is the initial proportion of resistance alleles in a population. 0000067616 00000 n Injection of plant growth regulators or interference with growth regulators during feeding is also reported. Factors affecting economic decisions by the producer cannot be ignored. Sampling for mites in a tomato field has shown that mite populations were highly aggregated and the number of samples required for just 60% precision was too large to be practical (Lange and Bronson, 1981; Park and Lee, 2007; Meck, 2010). Una de las principales características es la producción de hilos de seda en las colonias. So far, resistance has been reported in several countries for compounds such as organophosphates (OPs) (Anazawa et al., 2003; Sato et al., 1994), dicofol (Fergusson-Kolmes et al., 1991), organotins (Edge and James, 1986); hexythiazox (Herron and Rophail, 1993), clofentezine (Herron et al., 1993), fenpyroximate (Sato et al., 2004) and abamectin (Beers et al., 1998).

Las picaduras del ácaro producen una decoloración difusa y mate de la epidermis de los órganos en que vive, hojas, frutos y ramas tiernas. The Tetranychus urticae is a small mite, a polyphyllant plant that attacks different types of plants. Resistencia a Acaricidas en Tetranychus urticae (Koch) Asociada al Cultivo de Fresa en Zamora, Michoacán, México. Asimismo, lo invitamos a revisar nuestro calendario de eventos de capacitación para 2019. 0000028284 00000 n ; Rodríguez, M.J.C. The pest feeds mostly on the underside of the leaf, and the eggs are laid there, so it is crucial that miticide coverage be adequate there. AGROCIENCIA, 16 de agosto - 30 de septiembre, 2018 896 VOLUMEN 52, NÚMERO 6 las variables. If a more favorable alternative host is present and the pest can access it, this should weaken selection for resistant pests (Cantelo and Sanford, 1984). Also the insensitivity of AChE to demeton-S-methyl, ethyl paraoxon, chlorpyrifos oxon and carbofuran was identified in a German laboratory strain of T. urticae and a field collected strain from Florida (Stumpf et al., 2001). \�'���4l������W�"֧q. }; These environmental factors can convert plants which might be only poor hosts into very good hosts, resulting in mite population increase and crop damage. The body of a spider mite is separated into two distinct parts: (1) the gnathosoma and (2) the idiosoma. Necrosis, desiccation and detachment from the plant are thus manifested. Dominic J.

Además es importante acompañar esta estrategia con las medidas culturales y el control biológico para aumentar significativamente la eficacia del control de la plaga. 0000008926 00000 n In addition, there can be a delay in the response of some phytoseiids to phytophagous mites while the predators adapt to the glandular trichome defense of tomatoes (Drukker et al., 1997; Sato et al., 2011; van Houten et al., 2013). productos  de acuerdo a su modo de acción (MoA),  es la mejor estrategia para el control químico del ácaro. 0000070521 00000 n Intagri. (Fuente: INRA) Trips de las flores. The attacks of this small mite that can be very strong in the summer (with high temperatures and humidity), decrease with low temperatures around 10 degrees and in periods of rain. This releases cellular content of the epidermal cells which the mite sucks up using its rostrum. In optimal conditions, it reaches a high population density with considerable damage in all parts of the world where it is present. Citricos Cancrosis de los citricos . Serie Fitosanidad Núm. 0000154093 00000 n 0000002242 00000 n 0000003496 00000 n Damage can be seen as chlorosis of the leaves where the mites have been feeding. Gold fleck is thought to be a response to certain stresses the plant encounters during the season, such as high temperatures and humidity or TSSM or thrips feeding (De kreij et al., 1992; Ghidiu et al., 2006; Brust, 2014), or too high a level of calcium in the fruit as it is ripening (Den Outer and Van Veenendaal, 1988). Following this activity the leaves progressively show discoloration due to loss of pigment and chlorophyll, with consequent loss of photosynthetic capacity that leads to the death of the leaf. 0000004843 00000 n Previo a la liberación de P. persimilis hubo di- ferencias significativas entre las variedades con respecto a la abundancia de T. urticae por cm2, pero no, en el contenido de clorofila y porcentaje de daño.
