“…Test statistic, U (df = 34) = 28.5 presence of very dense hairs on the leaf surfaces, physically preventing the whitefly from effectively probing. Erb et al (1994) attributed the greater resistance of L. pennellii to T. vaporariorum to toxic exudates from glandular trichomes. Firdaus et al (2012) also suggest that the resistance found in L. pimpinellifolium is based upon the presence of type IV trichomes.…”

“…glabratum used in the study (those tested at 14 weeks rather than 8) displayed enhanced resistance, which has interesting implications for the present study in that the apparent resistance observed in L. pimpinellifolium in the present work at the 3-4 leaf stage (∼3 weeks old) may increase as the plants age. Erb et al (1994) studied the potential of another wild tomato species, Lycopersicon pennellii, to act as a source of resistance traits against T. vaporariorum. Hybrids produced using this species supported the fewest eggs and were the least attractive hosts of the whitefly.…”

The glasshouse whitefly, Trialeurodes vaporariorum, is an important pest of many crop plants including tomato, Solanum lycopersicum. Many wild tomato species exhibit a higher resistance to whiteflies. Therefore, locating the source of this enhanced resistance and breeding it into commercial tomato species is an important strategy to reduce the impact of pests on crops. Here, we assessed the pest resistance of Lycopersicon pimpinellifolium by comparing oviposition and feeding data from T. vaporariorum on this wild tomato species with data collected from a susceptible commercial tomato, S. lycopersicum var. 'Elegance'. The location of resistance factors was examined by use of electrical penetration graph (EPG) studies on these tomato species. Results show that whiteflies preferentially settled on the commercial tomato more often in 80 % of the replicates when given free choice between the two tomato species and laid significantly fewer eggs on L. pimpinellifolium. Whiteflies exhibited a shorter duration of the second feeding bout, reduced pathway phase probing, longer salivation in the phloem and more non-probing activities in the early stages of the EPG on the wild tomato species compared to the commercial tomato. These findings evidence that a dual mode of resistance is present in this wild tomato against T. vaporariorum: a post-penetration, pre-phloem resistance mechanism and a phloem-located factor, which to the best of our knowledge is the first time that evidence for this has been presented. These findings can be used to inform future breeding strategies to increase the resistance of commercial tomato varieties against this important pest.

“…The life history traits and/or population growth of T. vaporariorum have been studied on tomato (Solanum lycopersicum) in order to investigate the resistance of various tomato cultivars, breeding lines and hybrids to this pest (Romanow et al, 1991;Bas et al, 1992;Erb et al, 1994;Lucatti et al, 2010). In spite of the economic importance of T. vaporariorum, we found no published data on the life history of this pest on the most widely grown tomato genotypes in Serbian greenhouses.…”

“…Erb et al (1994) found a reduced number of laid eggs and F2 adults on two interspecific hybrids between S. lycopersicum and wild tomato species. In a five-day no-choice bioassay, Lucatti et al (2010) found the oviposition rate of T. vaporariorum to range from 0.2 eggs/day on a wild line S. habrochaites to 4.4 eggs/day on a S. lycopersicum breeding line resistant to root knot nematodes.…”

“…In that context, the interaction between host plants and T. vaporariorum can be an important element in the improvement of integrated pest management programs. Host plants (species, cultivars or hybrids) are known to affect the development, reproduction and population growth of T. vaporariorum (Erb et al, 1994;Fancelli and Vendramim, 2002;Kakimoto et al, 2007;Manzano and van Lenteren, 2009;Baldin and Beneduzzi, 2010) and their susceptibility to insecticides (Liang et al, 2007;Castle et al, 2009;Xie et al, 2011). In this bioassay, we evaluated the survival, reproduction, development and population growth of T. vaporariorum on five tomato genotypes popular on the Serbian market as a foundation for research that should improve programs of integrated management of this pest.…”

SuMMARYThe effects of five tomato genotypes (cv. Narvik and hybrids NS-6, Tamaris, Alliance and Marko) on the survival, reproduction, development and population growth of the greenhouse whitefly Trialeurodes vaporariorum were examined. A laboratory population of T. vaporariorum had been reared on tobacco plants for three years before the study. Females that laid eggs on the genotype Marko lived significantly longer and their offspring needed significantly shorter periods to develop than females on the genotype Narvik. The highest gross and net fecundity rates were found in females on the genotype Marko (36.74 eggs/ female and 27.93 eggs/female, respectively) and they differed significantly from the corresponding rates of females living on the genotype NS-6 (18.55 eggs/female and 15.33 eggs/ female), who had the lowest fecundity rates. The highest gross and net fertility rates were also found in females on the genotype Marko (31.24 adults/female and 23.73 adults/female), and they were significantly higher than those of females living on NS-6 (14.85 adults/female and 12.53 adults/female). Besides, net fertility rate of the females living on the genotype Narvik (13.80 adults/female) was also significantly lower than the rate of females on Marko. The instantaneous rates of increase showed no significant difference over a 10-day interval following the start of oviposition, while the increase rate was significantly higher on the genotype Marko after 12, 14 and 16 days, compared to the genotype NS-6. Eighteen, 20 and 22 days after the beginning of oviposition, the instantaneous rate of increase on the genotype Marko was significantly higher than it was on NS-6 and Narvik. Our data provide a basis for further research aiming to improve programs of integrated management of greenhouse whitefly.
