“…Most of the contact between the stylet bundle and plant tissue is with the mandibular stylets; small barb-like ridges at the apex of the mandibular stylets are believed to aid the piercing process, and to anchor the stylets into the plant tissue during feeding (Fig. 4.14b) (Rosell et al 1995;Hunter et al 1996). The mandibular stylets contain a pair Rosell et al 1995; in the original, the mandible on the right was displaced and in this modification was put back in its correct position relative to the stylet bundle; also delineation between the two maxillary stylets is enhanced in this modification) (TEM).…”

“…The posterior wall of the cibarial pump is the hypopharynx and is shaped as a longitudinal trough with its concave surface facing anteriorly (Harris et al 1996b;Hunter et al 1996). The anterior wall of the pump is the epipharynx, which is opposite the concave surface of the hypopharyngeal wall, and abuts against it when at rest.…”

“…The anterior wall of the pump is the epipharynx, which is opposite the concave surface of the hypopharyngeal wall, and abuts against it when at rest. The cibarial dilator muscles originate on the inner surface of the postclypeus, and insert in a longitudinal apodeme on the anterior side of the epipharyngeal wall (Harris et al 1996b;Hunter et al 1996) (Fig. 4.17).…”

“…4.17). The proximal part of this channel is the cibarium (referred to as the pharynx by Weber 1935) and forms the sucking pump; the distal part is the precibarium (Hunter et al 1996), also referred to as the hypocibarium (Harris et al 1996b), which connects the maxillary food canal to the cibarial pump.…”

“…A valve (termed precibarial by Hunter et al 1996, and cibarial by Harris et al 1996b) at the proximal end of the precibarium regulates the direction of fluid flow as the cibarial dilator muscles cycle between contraction and relaxation. The valve consists of a thickening of the epipharyngeal wall that is opposite a shallow depression in the hypopharyngeal wall (Fig.…”

A microscopic analysis of the morphology and ultrastructure of the digestive, salivary, and reproductive systems of adult Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) B type was conducted using light, scanning, and transmission electron microscopy. The internal anatomy of B. tabaci was found to be similar to that reported for Trialeurodes vaporariorum. In a microscopic analysis of the salivary glands, we have shown that each primary salivary gland is composed of at least 13 cells varying in morphology and staining differentially, while the accessory salivary glands are composed of four morphologically similar cells. We analyzed the course of the alimentary canal in B. tabaci, demonstrated the internal morphology of the organs, and clarified the location of the filter chamber relative to other organs in the whitefly. Our observations confirm that the pair of structures extending from the connecting chamber are caeca that may aid in fluid movement through the midgut and are not Malpighian tubules, as previously suggested. We confirm an earlier finding that the whitefly lacks Malpighian tubules, having instead specialized Malpighian-like cells within the filter chamber at the juncture with the internal ileum. Finally, we provide the first scanning electron microscopic analysis showing the reproductive organs of B. tabaci. Our investigation provides clarified terminology for several components of the digestive and excretory system. We also provide drawings and micrographs that will aid future researchers in localizing the internal organs of B. tabaci. We expect our analysis to provide a valuable tool for studying B. tabaci / plant virus interactions and physiological and biological aspects of this insect.

Ipomoviruses (genus Ipomovirus) are whitefly-transmitted viruses assigned to the family Potyviridae. They are characterised by filamentous flexible particles and a positive-sense single-stranded RNA (+ssRNA) genome. The viral genome is translated into a polyprotein precursor, which is processed into mature proteins and a short overlapping open reading frame. The genus Ipomovirus contains four accepted species and one unapproved species, and two other tentative members have recently been characterised. Ipomoviruses cause serious economic losses in many important crops, including cassava, sweet potato, cucurbits, tomato and aubergine. These viruses are transmitted by whiteflies in a non-circulative, semi-persistent manner, the virions being retained on the external surface of the vectors' mouthparts for a few days or weeks. Comparison of the available complete genome sequences of different ipomoviruses revealed differences in their genome organisation and a considerable variation in their proteins and conserved motifs that may reflect functional differences. This review summarises the current knowledge of the members within the genus Ipomovirus, focusing on genome organisation, taxonomic classification and the mechanism by which they are transmitted.
