Abstract

The epidemiology of tomato spotted wilt virus within a greenhouse is affected by: host plant species, environmental factors and pest control products. Native plants and weeds can act as reservoir hosts of the virus/thrips complex. Virus incidence within chrysanthemum cultivars is due to both virus susceptibility of cultivars and the cultivar feeding-preference of WFT. Virus latency occurred in all cultivars and was generally greater in virus-resistant cultivars. Therefore, visual inspection alone will not eliminate sources of virus from a greenhouse. The key environmental factor that affects virus spread is temperature, as it influences virus susceptibility of plant species, thrips population dynamics, and the overwintering ability of WFT. Biorational products have been identified that reduce WFT feeding, reproduction or virus transmission.
