Abstract
Six insect pests of potato, green peach aphid,Myzus persicae (Sulzer); potato leafhopper,Empoasca fabae (Harris); Colorado potato beetle,Leptinotarsa decemlineata (Say); tarnished plant bug,Lygus lineolaris (Palisot de Beauvois); red-legged grasshopper,Melanoplus femurrubrum (DeGeer); and southern army worm,Prodenia eridania (Cramer), were tested for their ability to transmit potato spindle tuber viroid (PSTV). PSTV infection was determined by a gel electrophoretic assay made 6 weeks after transfer of insects from infected to non-infected plants of the cultivar, ‘Katahdin.’ Plants grown from tubers of the original non-infected hosts were also assayed. PSTV was detected in only 2 of 183 test plants; these 2 plants had been infested with the tarnished plant bug. These results suggest that the insect species studied are relatively insignificant as vectors of PSTV.
Resumen
Seis insectos plagas de la papa: el pulgón de la papa,Myzus persicae (Sulzer); el saltahojas de la papa,Empoasca fabae (Harris); el escarabajo de Colorado,Leptinotarsa decemlineata (Say); el chinche manchado,Lygus lineolaris (Palisot de Beauvois); el grillo de patas rojas,Melanoplus femurrubrum (DeGeer); y el gusano ejército del surProdenia eridania (Cramer), fueron enzayados para determinar su capacidad de transmitir el viroide causal del tubérculo ahusado de la papa (PSTV). Infección por PSTV fué determinado con analisis de “gel electrophoresis” hecho seis semanas después de la transferencia de los insectos de plantas infectadas a no-infectadas, de la variedad “Katahdin.” Plantas nacidas de tubérculos huéspedes originales no-infectados fueron analizados también. PSTV fué detectado en unicamente 2 de las 183 plantas probadas; estas 2 plantas habían sido infectadas conLygus lineolaris. Estos resultados implican que las especies de insectos estudiados son relativamente no-significantes como vectores de PSTV.
