Abstract:Bemisia tabaci (Gennadius) biotype B has become a severe economic pest in recent years worldwide and infests more than 600 host plant species. In tomato it causes irregular fruit ripening and induces plant physiological disorders via transmitted geminiviruses such as Tomato yellow leaf curl virus. As a result, tomato yields are severely reduced. Presently, it is the most important pest of greenhouse-grown tomato plants in China. Previous researchers found that some wild tomato species were resistant or tolerant to B. tabaci. However, the effect of these wild species on growth of B. tabaci and the different responses among wild tomato species and cultivars are not well known. In this research, B. tabaci biotype B, reared on cabbage, was transferred to eight tomato accessions (three Solanum habrochaites, four S. lycopersicum and one S. pimpinellifolium). Oviposition, body size, rate of development, longevity, and survivorship were investigated. Bemisia tabaci deposited lowest eggs on accession LA1777 (S. habrochaites) and highest on 9706 (S. lycopersicum) from 10:00 to 14:00 on a sunny day (14 and 164 eggs, respectively). After egg-laying, the adults of B. tabaci were moved to a incubator maintained at 25°C and 60% RH with a 16/8 h (light/dark) photoperiod, and all life parameters were investigated. The first, second and fourth instars were larger on S. habrochaites than on the other accessions. However, the third instars were largest on accession 9706. The development time of B. tabaci from egg to adult was longest (29 days) on Lichun (S. lycopersicum) and shortest (21.5 days) on 9706. The longest development time from first to fourth instars was 16 days on Moneymaker (S. lycopersicum) and the shortest time was 10 days on Zaofen No.2 (S. lycopersicum). From egg to first instar, the development time was longer on 9706 (14 days) than on LA2329 (S. habrochaites; 9 days). The survivorship of B. tabaci from egg to adult was significantly higher on LA1777 (88.28%) than on Lichun (53.25%). Survivorship in the pupal stage was significantly higher on LA1777 (96.56%) than on 9706 (84.51%), and the other accessions did not differ significantly from 9706. Survivorship in the first instar was higher on 9706 (98.58%) than on To937 (S. pimpinellifolium; 91.08%); there was no significant difference between the other accessions and To937. Survivorship in the second and third instars did not differ significantly among all accessions. In fourth instar, survivorship was higher on PI134417 (S. habrochaites; 97.10%) than on 9706 (80.13%). After eclosion, the longevity of female B. tabaci on LA1777 was significantly shorter (5 days) than on Moneymaker (22 days). Oviposition on LA1777 was significantly lower (7 eggs/female) than on Zaofen No.2 (S. lycopersicum; 95 eggs/female). The results indicate that cultivated tomato is a better host plant for B. tabaci, whereas S. habrochaites accessions such as LA1777 and LA2329 show better resistance or tolerance to B. tabaci. The latter are useful germplasm for tomato breeding. There were consistent and significant differences in the life parameters, oviposition, female longevity and oviposition (after eclosion), but not in body size, rate of development and survivorship, between wild species and cultivars. Therefore, these three parameters are useful for evaluating resistance/susceptibility to B. tabaci in tomato.
