| description | To update information on whitefly species composition and occurrence of whitefly biotypes affecting annual crops in the Cauca Valley of Colombia, a new survey was coriducted in 2002-2003. Thirty-seven sites in 23 differerit locations were visited. Adult and pupal samples were taken from 11 crops. Differentiation between the species Ilemisia tabaci (Gennadius) and frialeurodes vaporariorurn (Westwood) was based on morphological characteristics of the pupae. Reconfirmation of species identity and differentiation between biotypes A and B was done by means of random amplified polymorphic DNA (RAI D s-PCR analysis). T. uaporariorum, the predominant species in 1997 (present iii 73% of the samples), now occupies a secondary place detected in only 22,7% of the samples. The Biotype A of B. tabaci (15,5% of the samples in 1997) was not found in any samples taken in 2002 2003 On the contrary the incidence of the B biotype increased from 11 S% in 1997 to 62 6% in 2003 Increased incidence of the B biotype was also evidenced by the common occurrence of such physiological disorders as irregular ripening of tomatoes, silver-leaf symptoms on squash and pod chlorosis on snap beans. These disorders had not been recorded in the Cauca Valley before. Snap beans, soybeans, pepper. sweet potato, and grapes were recorded as new host planta for the ¡3 biotype. A mix of T vaporariorum and biotype B was found in 14,6% of the samples The B biotype showed high levels of resistance to conventional insecticides and susceptibility to novel insecticides (neonicotinoids and insect growth regulators) The importance that these changes in species composition and biotypes of whitefly have to the regions agriculture are discussed. |

Para actualizar la informacion obtenida en el año 1997 sobre la composicion de especies y biotipos de moscas blancas en cultivos anuales en el Valle del Cauca, se hizo un nuevo reconocimiento en 37 localidades de 23 municipios del departamento. Se tomaron muestras de adultos y pupas en once cultivos. Por observación de las características morfológicas de las pupas se hizo la diferenciación entre las especies Bemisia tabaci (Gennadius) y Triateurocles vaporariorum (Westwood). La reconfirmación de la identidad de especies y la diferenciación entre los biotipos A y B de B. tabaci se realizó por medio de polimorfismo en ADN amplificado al azar (RAPD-PCR). T. vaporariorum, predominante en 1997 con 73% de las muestras ocupa ahora un lugar secundario con apenas 22 7% de las muestras El biotipo A de B. tabaci (en 1997 con 15,5°k de las muestras) no fue encontrado en ninguno de los muestreos realizados en 2002-2003. Por el contrario, la incidencia del biotipo B se incrementó de 11,5% en 1997 a 62,6% en 2003 Su mayor presencia se evidencio ademas por la comun ocurrencia de desordenes fisiologicos como la maduracion desuniforme en frutos de tomate el plateado de las hojas del zapallo y la clorosis de peciolos y vainas en habichuela que no habian sido senalados en el departamento Habichuela soya pimentón, batata y uva fueron registrados como nuevos hospedantes del biotipo B. En 14,6% de las muestras se hallo mezcla de biotipo B y T vaporariorum El biotipo B mostro altos niveles de resistencia a insecticidas convencionales y susceptibilidad a insecticidas novedosos (neonicotinoides y reguladores de crecimiento). Se discute la importancia que estos cambios en la composición de especies y biotipos de moscas blancas pueden tener para la agricultura de la región. 2005 2014-10-02T08:33:33Z 2014-10-02T08:33:33Z Journal Article https://hdl.handle.net/10568/44297 es Open Access |
