“…More recent works have revealed behavioral and electrophysiological responses to host plant volatiles (Pickett et al, 1992;Visser et al, 1996;Pickett and Glinwood, 2007), which presumably assist host-alternating aphids during their migration and return to seasonal hosts. Similar observations were made with whiteflies (Vaishampayan et al, 1975b;Mellor and Anderson, 1995;Bleeker et al, 2009) although, as in aphids, the simultaneous application of visual stimuli was often required to elicit chemotactic responses to host plant odors.…”

Most innate responses to color stimuli lead herbivorous insects to orient to "green" and "yellow" surfaces. Early research showed that aphid orientation to plants is influenced by foliar pigments and leads them to alight on leaves of a specific physiological state regardless of whether or not it is their actual host. In this study, we quantified the color preferences of four psyllids specialized on young to recently expanded leaves of different Eucalyptus hosts presenting distinct between (inter-specific) and within canopy (ontogenic) optical characteristics. Color preferences of Ctenarytaina eucalypti and C. bipartita were similar to those observed in aphids with more frequent selection of yellow and green stimuli, consistent with the coloration of their host leaves. However, attraction of Anoeconeossa bundoorensis and Glycaspis brimblecombei to a red stimulus contrasts strongly with the literature for hemipteran and herbivorous insects generally for which attraction to red is peculiar. Interestingly, both red-attracted species occur on the same host eucalypt, which expresses anthocyanic (red) young leaves. Our experiments demonstrate that these two species are sensitive to long wavelength radiation. Behavioral responses and modeling of putative "aphid-like" photoreceptors were conducted to investigate whether achromatic vision mediates perception of "red." Our results do not provide strong evidence for an intensity-dependant type of attraction. Nevertheless, the current knowledge of photoreceptors in Hemiptera identifies the achromatic pathway as the most likely mechanism for detecting long wavelengths. Thus, our findings highlight the need for physiological work with Psylloidae to elucidate the mechanisms responsible for such atypical responses. We discuss the ecological implications of our work in relation to red foliar pigments in expanding leaves of perennial plants which differs greatly from the thoroughly studied aphid-autumnal leaves system involving senescing foliage.

“…Furthermore, whiteflies can discriminate between different qualitative conditions in host plants, for example, differences in nitrogen fertilization, leaf position, aphid colonization and virus infection . Moreover, the ultrastructure of certain antennal sensilla of B. tabaci , T. vaporariorum and Aleyrodes proletella indicates an olfactory function . Odorant‐binding and chemosensory proteins have been detected in B. tabaci using transcript analysis, and certain volatile compounds have been shown to bind to chemosensory proteins of B. tabaci .…”

Prospects for management of whitefly using plant semiochemicals, compared with related pests

Whitefly (Hemiptera: Sternorrhyncha: Aleyrodidae) pests, including the tobacco whitefly, Bemisia tabaci, and the greenhouse whitefly, Trialeurodes vaporariorum, are important economically in agriculture. Whiteflies are controlled mainly by synthetic insecticides but resistance to these is evolving rapidly. A semiochemical‐based management strategy could provide an alternative to the use of insecticides, by exploiting natural volatile signalling processes to manipulate insect behaviour. Whitefly behaviour is affected by differences in plant odour blends. Selected compounds have been suggested as putative semiochemicals, but in only a few studies have potential volatiles been characterized by electrophysiology or olfactometry. Application of antennal preparation methods from closely related families, the aphids (Hemiptera: Aphididae) and psyllids (Hemiptera: Psyllidae), may help to facilitate whitefly electroantennography. Behavioural bioassays are essential to identify the repellent or attractant effect of each semiochemical. The relevance of semiochemicals in whitefly management needs to be evaluated in the respective cultivation system. Although the value of semiochemicals against whiteflies has not been demonstrated in the field, there is an emerging range of possible field applications and some promising prospects. Overall, the olfactory system of whiteflies needs to be elucidated in more detail. © 2018 The Authors.

“…In phloem feeders, host plant selection may be divided into four consecutive steps: (1) prelanding behaviour, (2) leaf surface exploration and probing of subepidermal tissues, (3) deep probing of plant tissues and (4) evaluation of the phloem sap . The cues that whiteflies can use for assessing the suitability of plants as hosts prior to landing are limited by the sensory apparatus that they possess, the olfactory sensillae on their antennae . In B. tabaci , plant volatiles are likely to play an important role in host selection prior to landing, as Jing et al showed that the insect can recognise several plant odours in Y‐shaped olfactometers, without any visual references.…”

Bemisia tabaci females from the Mediterranean (Q) species detect and avoid laying eggs in the presence of pyriproxyfen, a juvenile hormone analogue

Pyriproxyfen caused reduced oviposition and enhanced mature oocyte accumulation in pyriproxyfen-resistant and pyriproxyfen-susceptible females. These findings can be explained by two alternative mechanisms: pyriproxyfen-regulated physiological arrest of oviposition, involving hormonal regulation of myotrophic factors, or the hierarchy-threshold behavioural theory of host choice, in which pyriproxyfen-treated plants are defined as low-quality hosts. Aspects of application are discussed.
