Abstract

The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is an economically important agricultural pest globally that costs growers billions of dollars to control. Given the pest status of B. tabaci and its propensity for invasiveness, a detailed work to resolve the prevalence of B. tabaci genetic groups is warranted. Hence, we analyzed mitochondrial cytochrome oxidase I sequences from 71 samples of B. tabaci to determine the prevalence of genetic groups on various host plants in India. Results revealed the prevalence of the 4 previously existing genetic groups, namely Asia-I, Asia-II-7, Asia-II-8, and Middle East Asia Minor-1 (MEAM-1), and of a new group called Middle East Asia Minor-K, which is genetically close (92.6%) to MEAM-1.

 

Resumen

La mosca blanca Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) es una plaga económicamente importante para la agricultura a nivel mundial que cuesta miles de millones de dólares a los productores en controlar. Dado el estatus de plaga de B. tabaci y su propensión para invadir, se justifica un trabajo detallado para resolver la prevalencia de los grupos genéticos de B. tabaci. Por lo tanto, se analizaron las secuencias mitocondriales de citocromo oxidasa I de 71 muestras de B. tabaci para determinar la prevalencia de grupos genéticos en varias plantas hospederas en la India. Los resultados revelaron que la prevalencia de los 4 grupos genéticos ya existentes, Asia-I, Asia-II-7, Asia-II-8 y Asia de Medio Oriente Menor-I (MEAM-I) y de un nuevo grupo llamado Asia de Medio Oriente Menor-K, que es genéticamente cercano (92.6%) al MEAM-1.
