“…In chrysanthemum, large genetic variation in thrips resistance was shown for all measured parameters. This corresponds to the results of other authors, who found the same range of variation in 'silver' damage among chrysanthemum cultivars (Broadbent et al, 1990;van Dijken, 1992). In spite of a high thrips pressure during ten weeks, plants without any feeding damage were present.…”

In a choice‐experiment, 42 chrysanthemum cultivars were screened for resistance to Frankliniella occidentalis (Pergande). Oviposition preference, two types of feeding damage and thrips numbers per flower were recorded as measures of resistance. A large genetic variation in thrips resistance was found among the cultivars screened. The amount of feeding damage was strongly determined by oviposition preference. Besides, a positive correlation was found between the oviposition preference in non‐flowering chrysanthemums (number of eggs) and flowering chrysanthemums (number of thrips per flower). Thrips feeding on young, developing tissues, causes growth damage because affected cells are unable to expand and leaves become distorted. Thrips feeding on older, expanded leaves causes cells to become filled with air, resulting in ‘silver’ damage. The amounts of growth‐ and ‘silver’ damage were negatively correlated suggesting that thrips chose either young or older leaves to feed on. The order of resistance among cultivars did not change during the experiment. In order to get more insight in resistance mechanisms the influence of some plant‐ and flower characters on resistance was examined. The plant characters height, number of leaves, flower production and flower weight were all negatively correlated with resistance. It is suggested that tall chrysanthemum cultivars with many and large flowers may invest less in defence than smaller cultivars, and therefore are more damaged by thrips.

“…These results stressed the importance of tomato plants as potential sources for newly infected thrips, and suggested that the removal of the TSWVinfected plants in a crop could have positive effects in the general control of the disease. Similar differences in transmission efficiencies of TSWV isolates due to acquisition host species have been reported for other hosts (Broadbent et al, 1990;Ullman et al, 1992b;Wijkamp et al, 1995) and have been related to the differential distribution of TSWV in host tissues (German et al, 1992) or to differential feeding preferences of the thrips (Lewis, 1973). Although it has been suggested that TSWV can cause pathological effects on WFT (Robb, 1989), it should be emphasized that the transmission data compared in this paper were not biased by possible deleterious effects of TSWV in the thrips.…”

The abilities of different isolates of tomato spotted wilt tospovirus (TSWV) collected from northeastern and eastern Spain to infect 10 host species, and to be acquired and transmitted by the western flower thrips (WFT), Frankliniella occidentalis were compared. Two isolates of TSWV from a single source plant could be separated according to the different type of local lesions they induced in Nicotiana glutinosa. Host ranges of the studied TSWV isolates were very similar, but differences were found in the symptoms induced and in their capacity to infect specific hosts systemically. Lycopersicon esculentum and Datura stramonium were evaluated for their potential as virus acquisition host species. The proportion of transmitter adult thrips obtained from WFT larvae fed on L. esculentum was greater than from D. stramonium. No differences were detected between TSWV isolates in their ability to be acquired and transmitted by WFT. No evidence was obtained of alterations in TSWV particles which could affect WFT transmissibility due to the repeated mechanical transfers used to clone the isolates. Our findings do not support the existence of pathological effects of TSWV on WFT.

“…Transmission of TSWV by T. tabaci also seems to be affected by the host on which the virus is acquired. Effects of the acquisition host on transmission have been observed in many studies (Sakimura, 1939;Broadbent et al, 1990;Roca et al, 1997). Acquisition from D. stramonium resulted in better transmission than that from E. sonchifolia, although the second species has been reported as a good virus source for T. tabaci (Sakimura, 1963) and F. occidentalis (Bautiste et al, 1995).…”

The transmission of tomato spotted wilt tospovirus (TSWV) by Thrips tabaci collected from leek was studied using the petunia local-lesion leaf-disc assay. After an acquisition-access period of 72 h given to newborn larvae up to 8 h old, the efficiency of transmission by adults was determined in three inoculation-access periods of 48 h. This efficiency varied for six T. tabaci populations from 0·7 to 11·6% in experiments using the Greek TSWV isolate GR-04. Males were more efficient transmitters than females (19 out of 176 versus five out of 494). Frankliniella occidentalis transmitted the same virus with a higher efficiency (34·8%). The transmission rate differed also among TSWV isolates, as shown in tests with four T. tabaci using two isolates. The virus was more efficiently acquired from infected leaf material of Datura stramonium than from that of Emilia sonchifolia. Plants of the latter species were more susceptible than Nicotiana tabacum in thrips transmission tests.
