Entomol. Viruses 9:E4. Absolute quantification of cassava brown streak virus mRNA by real-time qPCR. Phytopathology 101, 1191–1201. doi: 10.1002/ps.3793, Legg, J. P., Somado, E. A., Barker, I., Beach, L., Ceballos, H., Cuellar, W., et al. A technique for electronically recording aphid feeding and salivation. Mean durations of individual waveform events. Out of 60 cassava cuttings obtained from the field, one tested positive for UCBSV and was not planted. For the comparative study on the effects of wire thickness, 12.5 μm thick and 2 cm long gold wires (EPG Systems, Wageningen, The Netherlands) were used in the same brass nail-copper wire configuration. An investigation of the effect of using 12.5 μm gold wire instead of the thinner 2.5 μm platinum wire on SSA1-SG3 whiteflies feeding on cassava showed large and statistically significant differences. . Springerplus 3:641. doi: 10.1186/2193-1801-3-641. doi: 10.1046/j.1570-7458.2003.00093.x, Johnson, D. D., and Walker, G. P. (1999). doi: 10.1111/jen.12197, Tajebe, L. S., Guastella, D., Cavalieri, V., Kelly, S. E., Hunter, M. S., Lund, O. S., et al. 65, 219–237. Manihot flabellifolia Pohl, wild source of resistance to the whitefly Aleurotrachelus socialis Bondar (Hemiptera: Aleyrodidae). Consistently high incidence of Wolbachia in global fig wasp communities. Exp. Agric. Prevalence and genetic diversity of endosymbiotic bacteria infecting cassava whiteflies in Africa. Insecticide Resistance Monitoring in Whitefly (Bemisia tabaci) (Hemiptera: Aleyrodidae) in Oman. Appl. Soc. The sweetpotato whitefly, Bemisia tabaci (Gennadius), is a worldwide pest of numerous agricultural and ornamental crops. Their identity is assumed to be SSA1-SG3 since they came from the pure colony on cassava. 72, 47–57. Comparison between the MED and IO showed no significant differences. RNAi-mediated resistance to whitefly (Bemisia tabaci) in genetically engineered lettuce (Lactuca sativa). Genome Biol. Control of However, recent studies using more comprehensive techniques, such as genome-wide single nucleotide polymorphism (SNP) markers, indicate that mtCOI is not the best taxonomic marker as it does not accurately represent the genetic differences between populations of cassava-colonizing whiteflies (Wosula et al., 2017). Sci. In addition, there is a great risk of spread to West Africa, the biggest cassava producing region in Africa, where a CBSD epidemic would have devastating consequences on food security (Legg et al., 2014a,b). After the first studies established the EPG technique for whiteflies it has subsequently been used on B. tabaci in studies focusing on virus transmission, host resistance factors and insecticide effects (Walker and Perring, 1994; Jiang et al., 1999, 2000, 2001; Johnson and Walker, 1999; Jiang and Walker, 2001, 2003; Johnson et al., 2002; Rodríguez-López et al., 2011, 2012; Liu et al., 2012, 2013; Civolani et al., 2014; Zhou, 2014; Prado Maluta et al., 2017). View the article PDF and any associated supplements and figures for a period of 48 hours. Mean duration of the phloem ingestion events (E2) was also significantly lower on cassava (Table 1), as well as the number of those events (Table 2). Comparing the regional epidemiology of the cassava mosaic and cassava brown streak virus pandemics in Africa. . Entomol. Phytopathology 56, 1127–1131. (2017). Furthermore, not all MED whiteflies had sustained (>10 min) phloem ingestion (E2) resulting in the mean number of 0.8 sustained phloem ingestion (E2) events in 12 h, while on sweet potato they had 3.1 (Table 4). Years of research concluded that B. tabaci and changes in its populations play the main role in driving the outbreaks and spread of both CMD and CBSD. Keywords: cassava, EPG, whitefly, sweet potato, Bemisia tabaci, feeding behavior, Citation: Milenovic M, Wosula EN, Rapisarda C and Legg JP (2019) Impact of Host Plant Species and Whitefly Species on Feeding Behavior of Bemisia tabaci. Electronic recording of penetration behaviour by aphids. In addition to directly feeding on plants, it also acts as a vector of plant viruses of cultivated and uncultivated host plant species. Biol. Interestingly, different E2 waveform variants as described by Zhou (2014) were also occasionally observed in this study. Isolation and Classification of Fungal Whitefly Entomopathogens from Soils of Qinghai-Tibet Plateau and Gansu Corridor in China. Transmission and host range of the tomato yellow leaf curl virus. Genetic diversity of Bemisia tabaci species colonizing cassava in Central African Republic characterized by analysis of cytochrome c oxidase subunit I. PLoS ONE 12:e0182749. Bemisia tabaci nomenclature: lessons learned. Each phloem ingestion (E2) event was preceded by a phloem salivation waveform (E1). Host Plant Affects Symbiont Abundance in Bemisia tabaci (Hemiptera: Aleyrodidae). Feeding Experience of Bemisia tabaci (Hemiptera: Aleyrodidae) Affects Their Performance on Different Host Plants. The varieties of host plant, their distribution and the dominant species of natural enemies of B. tabaci in different regions of China are discussed. Comparison of biological parameters between the invasive B biotype and a new defined Cv biotype of Bemisia tabaci (Hemiptera: Aleyradidae) in China. doi: 10.1023/A:1015843219849. We also thank the Agris Mundus masters program which through the Erasmus Mundus EU project which financially supported the study. Selected detailed EPG parameters describing whitefly-plant interactions. “Albert” is known to be preferred by whiteflies, while the tomato cultivar—Moneymaker—is extensively used in the scientific literature. The most commonly used taxonomic character is a segment of the mitochondrial gene for cytochrome oxidase I (mtCOI) which divides the species complex into at least 34 major species (Boykin et al., 2012; Boykin and De Barro, 2014).

The effect of this method was examined by Walker and Perring (1994) and they showed that thicker wire significantly impairs the mobility of whiteflies, although this effect was not quantified.
