This research sought to identify the aphid virus vector species associated with lettuce and broccoli crops in Spain, and to determine their population dynamics and ability to transmit Lettuce mosaic virus (LMV). Green tile traps and Moericke yellow water-pan traps were used to monitor aphid flights ...

Cucumber mosaic virus (CMV) causes a serious disease of narrow-leafed lupin (Lupinus angustifolius). It is seed-borne in lupin and seed-infected plants act as the primary virus source for secondary spread by aphid vectors within crops. Infection with CMV causes yield losses of up to 60% in epidemic ...

The acquisition of tospoviruses by thrips vectors is restricted to a well defined time period during the first and early second larval stages, when there is a temporary association between mid-gut, visceral muscles and salivary glands. This association is the result of a displacement of the brain...

Three genera of plant viruses, Begomovirus (Geminiviridae), Crinivirus (Closteroviridae) and Ipomovirus (Potyviridae), contain members that infect sweet potato (Ipomoea batatas) and are transmitted by whiteflies. The begomoviruses, Sweet potato leaf curl virus (SPLCV) and Ipomoea leaf curl virus...

Aphid species were counted on citrus trees in orchards in Valencia, Spain, in the spring and autumn of 1997, 1998 and 1999. Moericke yellow water traps, the 'sticky shoot' method and counts of established colonies were used in extensive surveys in which 29 502 aphids were recorded and identified. ...
