ABSTRACT.-
Population changes of Scaghytopius spp., possible vectors of Blueberry Stunt Disease (9880), were monitored during 1989, 1990 and 1991 using yellow sticky traps and a D?VacR aspirator. WW, S. frontaljs and S. mshowed two population peaks, one after petal fall stage and a larger second peak in late summer to early fall. Healthy, cv. Bluecrop highbush blueberry plants were placed under stunt-diseased bushes in the field for 2-wk periods during 1989 and 1990. These plantsmand some of the leafhoppers trapped during 1990 and 1991 were tested for MLO infection with a DNA probe (pAY22) that detected BBSD-MLO. The percentage of plants and the number of Seagnxtggiug spp. That were MLO?positive tended to follow the same bimodal distribution found in the population studies. BBSD transmission tests were performed with We spp. collected from the field. MLO transmission was achieved with 5. masstalmie. 5. scum. and S. tw-n 11' .
