J Chem Ecol. 2017 Jan;43(1):53-65. Qualitative and Quantitative Differences in Herbivore-Induced Plant Volatile Blends from Tomato Plants Infested by Either Tuta absoluta or Bemisia tabaci. Among headspace volatiles released by tomato plants exposed to herbivory by T. absoluta (TA), B. tabaci (BT), or no herbivory (control, C), a total of 80 VOCs were assigned, of which 68 compounds were present in all treatments, whereas 75 compounds were detected in at least one of the herbivory treatments (Table 1).
Control plants emitted 70 of these VOCs, BT-infested plants 75 VOCs and TA-infested plants 80 VOCs. Table 1 Volatile compounds detected in the headspace of tomato plants without herbivore infestation (C), tomato plants infested with Bemisia tabaci (BT) and tomato plants infested with Tuta absoluta (TA) according to their elution order in a chromatographic window Qualitative differences were found for three VOCs (31, 42, 54) that only occurred in headspace samples from TA-infested plants. Major quantitative differences were found for many VOCs among plants exposed to one of the two herbivory treatments (Table 1). Table 2.

SCIENCEMAG 14/12/16 Genome sequence reveals why the whitefly is such a formidable threat to food security. ITHACA, NY–Researchers have sequenced the genome of the whitefly (Bemisia tabici), an invasive insect responsible for spreading plant viruses worldwide, causing billions of dollars in crop losses each year.
Advertisement The genome study, led by Associate Professor Zhangjun Fei of the Boyce Thompson Institute (BTI), offers many clues to the insect's remarkable ability to resist pesticides, transmit more than 300 plant viruses, and to feed on at least 1,000 different plant species. Published today in the journal BMC Biology, the study will serve as a foundation for future work to combat this global pest. "Whitefly is an economically important pest for agriculture crops. It causes direct damage and also is a major vector for viruses, like Tomato yellow leaf curl virus, Cassava mosaic virus and Cassava brown streak virus, so it creates huge crop losses and poses serious threats to food security, especially in Africa and other parts of the developing world," said Fei. BMC 14/12/16 The draft genome of whitefly Bemisia tabaci MEAM1, a global crop pest, provides novel insights into virus transmission, host adaptation, and insecticide resistance.
Genome sequencing, assembly, and annotation Genomic DNA was isolated from approximately 6500 haploid male individuals from a B. tabaci MEAM1 colony established from a single female collected at the USDA-ARS in Charleston, SC, USA in April 2013, as described in Chen et al. .
The colony was validated as MEAM1 using primers specific to the mitochondrial cytochrome oxidase I (MtCOI) gene. Pakistan J. Zool., vol. 47(6), pp.1511-1515, 2015.

Abstract Since Panayiotis Gennadius first identified the whitefly, Aleyrodes tabaci in 1889, there have been numerous revisions of the taxonomy of what has since become one of the world's most damaging insect pests.
Most of the taxonomic revisions have been based on synonymising different species under the name Bemisia tabaci. It is now considered that there is sufficient biological, behavioural and molecular genetic data to support its being a cryptic species complex composed of at least 34 morphologically indistinguishable species. The first step in revising the taxonomy of this complex involves matching the A. tabaci collected in 1889 to one of the members of the species complex using molecular genetic data. To do this we extracted and then amplified a 496 bp fragment from the 3′ end of the mitochondrial DNA cytochrome oxidase one (mtCOI) gene belonging to a single whitefly taken from Gennadius' original 1889 collection.

ECOLOGICAL ENTOMOLOGY 14/07/16 Natural enemy impacts on Bemisia tabaci (MEAM1) dominate plant quality effects in the cotton system. 1.
Plant quality (bottom-up effects) and natural enemies (top-down effects) affect herbivore performance. Furthermore, plant quality can also influence the impact of natural enemies. 2. Lower plant quality through reduced irrigation increased the abundance of the cryptic species from the Bemisia tabaci complex [hereafter B. tabaci Middle East Asia Minor 1 (MEAM1)], but not its natural enemies on cotton. It was therefore predicted that lower plant quality would diminish the impact of natural enemies in regulating this herbivore.

(Hemiptera: Aleyrodidae) was observed to have completed its reproductive cycle from the egg to the adult on maize (Zea mays L.). Field and screenhouse studies were carried out to investigate the durability of this putative and unprecedented adaptation to a grass host. Analysis of the mitochondrial COI gene sequence identified the maize-associated B. tabaci as the exotic B biotype (major clade North Africa–Mediterranean–Middle East). Results showed that whiteflies migrated from soybean crops and successfully established in maize plants. Females exhibited a preference for oviposition primarily on the first and second leaves of maize, but were also able to colonise developing leaves. This is the first report of the B biotype completing its development on maize plants. J Virol. 2015 Oct;89(19):9791-803.

The Panel was also requested to identify risk management options and to evaluate their effectiveness in reducing the risks to plant health posed by these organisms. After consideration of the evidence, the Panel reached the following conclusions: With regard to the assessment of the risks to plant health: Viruses can enter with infected plant material and with insects carrying the viruses (viruliferous insects).

The silverleaf whitefly, Bemisia tabaci, is a species complex comprising several biotypes/cryptic species. It has over 500 host plants, to which damage is caused by the adult flies feeding, but they also vector a range of plant viruses. Control of the whitefly is principally by insecticide spraying, which can be of limited effectiveness as the pest develops resistance, and chemical modes-of-action or withdrawn from use. This project will seek to develop genetic tools for new management strategies against this pest. Current genetic control approaches involve development of transgenic strains showing a self-limiting trait.
For instance, engineered genetic sexing allows the production of male-only cohorts, which after release in the field will mate with wild counterparts, producing no female adult progeny and thereby reducing the pest population. Working with Bemisia tabaci, the student will develop transformation methods and test construct components.
