Left - Bemisisa tabaci adult; Right - late fourth nymph (eyes exhibiting red pigment diffusion and yellow body pigment of developing adult visible)
Tobacco (Nicotiana tabacum) plants that over-express the MYB transcription factor PAP1 (production of anthocyanin pigment 1}, which activates the phenylpropanoid-biosynthesis pathway. The PAP1 tobacco plants displayed two different pigment patterns. One type had solid purple leaves CAP purple - right), while the other type had primarily purple-veined leaves with a green background (PAP green -left). This transgenic manipulation allowed us to investigate the effect of high levels of phenylpropanoids/flavonoids on the transcriptomic responses, host selection, oviposition, development and survival of Bemisia tabaci.
Monitoring Bemisia tabaci life history traits (egg laying, development, survival) under "real" open-field conditions.
The data collected is incorporated into pest risk assessment and simulation models for developing comprehensive management planning systems of both natural and agricultural ecosystems in response to climate change.
Videotape recording of Bemisia tabaci host selection behavior in homogeneous (two plants/leaves of the same type)
or heterogeneous (two plants/leaves from different types) habitats
Bemisia tabaci courtship and mating behavior.
Left - Wing movement, Middle - Abdominal movement and Body pushing; Right - Copulatory organ contact.
Silencing Bemisia tabaci genes through feeding on transgenic tobacco plants expressing dsRNA of the P450 gene CYP6CM1
Insecticide resistance in Bemisia tabaci.
Binding site model of the complex formed by the detoxification enzyme CYP6CM1 and the insecticide imidacloprid. Imidacloprid (dark green carbon atoms) is bound with its imidazolic group positioned at an average distance of 3.5 A between the putative hydroxylation site and the heme-bound oxygen atom (heme is displayed with yellow carbon atoms)
Monitoring Bemisia tabaci life history traits (egg laying, development, survival) under "real" open-field conditions.
The data collected is incorporated into pest risk assessment and simulation models for developing comprehensive
management planning systems of both natural and agricultural ecosystems in response to climate change.
Routine daily life in the laboratory.
Fluorescent in-situ htbridization (FISH) of Bemisia Tabaci. RNA was labeled with Cy3 (red) probe. Blue - the general DNA stain 4',6-diami dino-2-henylindole (DAPI)
