“…However, even for the same plant species, whitefly preference is not the same across different cultivars. Trialeurodes vaporariorum is highly attracted to some commercially available tomato cultivars as compared with wild tomato species ( Solanum habrochaites and Lycopersicon pimpinellifolium L.) (Lucatti et al, 2010; McDaniel et al, 2016). This variable attraction may depend on the VOC properties of the eggplant and tomato cultivars, as the chemical compounds manipulating the behavioral responses of T. vaporariorum are less known except their attraction studied for the sexual pheromone (Yin and Maschwitz, 1983) and tomato leaf volatiles (Tsueda et al, 2014).…”

The behavior of the greenhouse whitefly, Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae), is known to be affected by plant volatile cues, but its attraction or repellent to specific volatile cues has not been deeply studied yet. Therefore, the aim of our study was to identify the most attractive plant among cultivars of tomato (Solanum lycopersicum) and eggplant (Solanum melongena) to evaluate the volatiles of plants to identify the chemical compound(s) that attract T. vaporariorum. We speculated that whitefly–host plant interaction primarily depends on plant volatile emissions and that once the plant is damaged, it might attract more whiteflies. Three intact (uninfested) tomato, four intact eggplant cultivars and whitefly infested plants of the most whitefly attractive tomato and eggplant cultivars were examined by behavioral assay experiments for attractiveness to T. vaporariorum and headspace volatile were determined by solid-phase microextraction (SPME) and gas chromatography-mass spectrometry. Whiteflies had the highest preference for the intact eggplant Kuai Yuan Qie (KYQ) among the eggplant and the tomato plant cultivars in bioassay experiments. Although both male and female whiteflies were significantly more attracted to infested KYQ plants than to intact plants, whitefly females did not select conspecific-infested YG plants. The volatile emissions among different plant cultivars in individual species and infested versus intact plants were significantly different. Among these volatiles, identified major green leaf volatiles [(Z)-3-hexen-1-ol] and terpenoids [α-pinene, (E)-β-caryophyllene, α-humulene, azulene] showed a constitutive relationship with the most whitefly preference plants. Our findings provide new insights into the chemical compounds that attract or repel whiteflies.

“…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. The adult survival rates ranged from 0.0 females/day to 0.8 females/day.…”

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.

“…En estudios realizados por Lucatti et al (2010) con genotipos de Solanum lycopersicum L., sugirieron que la variación entre sus poblaciones a la incidencia de la mosca blanca posibilita la selección de genotipos con cierta resistencia al insecto para el mejoramiento genético y la obtención de variedades resistentes. Aquellos genotipos que mostraron menor incidencia de T. vaporariorum podrían ser utilizados en el mejoramiento genético de gerbera para desarrollar variedades resistentes o tolerantes a esta plaga, lo que implicaría una disminución en el uso de insecticidas destinados a su control.…”

La existencia de variación natural a diferentes niveles de infestación de mosca blanca (Trialeurodes vaporariorum) en genotipos de gerbera (Gerbera hybrida) posibilita la existencia de diferentes niveles de resistencia o susceptibilidad al insecto. En esta investigación se evaluó la variación natural de gerbera a la incidencia de T. vaporariorum. En un diseño de bloques completos al azar, se analizaron diez genotipos de gerbera en diferentes etapas fenológicas sin incidencia (SI) y con incidencia (CI) de mosca blanca. Se contabilizaron ninfas, en un cm2 al centro del envés de las hojas y total de adultos por hoja. Se midieron el contenido relativo de clorofila (USPAD), el contenido de compuestos fenólicos (Cf), la actividad enzimática de las peroxidasas (AePOX) y la capacidad antioxidante DPPH (Caox). Los genotipos de gerbera mostraron diferencias significativas en la incidencia de la mosca blanca (p≤ 0.01), así como en Cf, AePOX y Caox, tanto en SI como CI (p≤ 0.01), lo cual sugiere diferencias en la preferencia del insecto a su hospedero y en la capacidad de respuesta de los genotipos a la mosca blanca. En CI respecto a SI, incrementaron el contenido de Cf (1.4 veces), la AePOX (4 veces) y la Caox (12 veces). USPAD disminuyó en el genotipo con la mayor incidencia del insecto (-4%). Las correlaciones significativas entre número de insectos (ninfas) con Cf (-0.71**) y AePOX (-0.65**) y Caox con Cf (-0.73**) y AePOX (-0.76**), mostraron que la alimentación del insecto interfiere en el metabolismo de sus hospederos y desencadena respuestas integrales en el mecanismo de defensa de las plantas, con diferencias en resistencia aprovechables en mejoramiento genético.
