“… Mann et al (2009) also observed a similar phenomenon and concluded that a shift in attraction to healthy plants over time facilitated the increased virus spread. The early attraction of the whiteflies to the diseased plants could be driven by a set of favorable volatile cues emanated from virus-infected plants ( Fereres et al, 2016 ; Wang et al, 2017 ; Shi et al, 2021 ). Previous studies have established that virus-induced host phenotypes entail an elevated emission of volatile blends normally used by vectors for host location.…”

“…Although plant palatability to insects is influenced by the nutritive status of the plant (such as sugars and amino acids), volatile organic compounds (VOCs) play a crucial role in manipulating the behavior of insect vectors. Begomoviruses attenuate plant defense responses and cause dynamic changes in the emission of volatiles between healthy and virus-infected plants ( Shi et al, 2021 ). A complex set of virus-vector interactions modulates the behavior of B. tabaci ( Mauck et al, 2010 ; Nogia et al, 2014 ; Jaime et al, 2020 ) to ensure efficient transmission.…”

“…A complex set of virus-vector interactions modulates the behavior of B. tabaci ( Mauck et al, 2010 ; Nogia et al, 2014 ; Jaime et al, 2020 ) to ensure efficient transmission. Many studies ( Fereres et al, 2016 ; Wang et al, 2017 ; Shi et al, 2021 ) have demonstrated the varying effects of volatile cues emitted by virus-infected plants on the behavior of the whitefly B. tabaci . Chen et al (2017) stated that odors dictate B. tabaci selection between healthy and Tomato Leaf Curl Virus (TYLCV)-infected plants, wherein virus-infected plants released phenol and 2-ethyl-1-hexanol, leading to the attraction of the vector B. tabaci toward infected plants, while Fang et al (2013) recorded the differential effects of volatiles, namely, β-myrcene, thymine, β-phellandrene, (+)-4-carene, α-humulene and caryophyllene, emitted by Tomato yellow leaf curl virus TYLCV-infected tomato plants on the B and Q biotypes of B. tabaci .…”

Manipulation of insect vector behavior by virus-induced plant volatiles is well known. But how the viral disease progression alters the plant volatiles and its effect on vector behavior remains less explored. Our studies tracked changes in volatile profile in progressive infection stages of cotton leaf curl virus (CLCuV) infected plants and their effect on B. tabaci behavior. Significant differences in virus titers were noticed between progressive infection stages showing distinct symptoms. Whiteflies initially settled on CLCuV infected plants, but their preference was shifted to healthy plants over time. GC-MS analysis revealed subtle quantitative/qualitative changes in volatile organic compounds (VOCs) between the healthy and selected CLCuV infection stages. VOCs such as hexanal, (E)-2-hexen-1-ol, (+)-α-pinene, (−)-β-pinene, (Z)-3-hexen-1-ol, (+)-sylvestrene, and (1S,2E,6E, 10R)-3,7,11,11-tetramethylbicycloundeca-2,6-diene (Bicyclogermacrene) were associated with the infection stage showing upward curling of leaves; (E)-2-hexen-1-ol, β-myrcene, β-ocimene, and copaene were associated with the infection stage showing downward curling. Validation studies with eight synthetic VOCs indicated that γ-terpinene elicited attraction to B. tabaci (Olfactometric Preference Index (OPI) = 1.65), while β-ocimene exhibited strong repellence (OPI = 0.64) and oviposition reduction (66.01%–92.55%). Our studies have demonstrated that progression of CLCuV disease in cotton was associated with dynamic changes in volatile profile which influences the behavioural responses of whitefly, B.tabaci. Results have shown that VOCs such as (+)-α-pinene, (−)-β-pinene γ-Terpinene, α-guaiene; 4- hydroxy- 4 methyl-2- pentanone and β-ocimene emitted from Begomovirus infected plants could be the driving force for early attraction and later repellence/oviposition deterrence of B. tabaci on virus-infected plants. The findings of this study offer scope for the management of whitefly, B. tabaci through semiochemicals.

Bemisia tabaci (Gennadius) is an important global invasive pest, which damages plants by feeding on phloem sap and causes great losses to agricultural production. At present, the management of B. tabaci still relies on insecticides. Based on the emergence of the insecticide resistance and the pursuit of environmental friendliness, more green control methods have been generated. Insects rely on odorant-olfactory proteins to identify specific volatiles and locate hosts, and these volatiles can be exploited in agricultural pest control. This study evaluated the control efficacy of d-limonene, a common volatile in three avoidant plants. Our results showed that d-limonene had a repelling effect on B. tabaci, and the LC50 value of d-limonene was 81.623 ppm. Moreover, the LC50 of bifenthrin and flupyradifurone were reduced by 25.2% and 38.7% when mixed with d-limonene. The underlying molecular mechanism of d-limonene recognition by B. tabaci was investigated. Treating B. tabaci with dsBtabOBP3 increased the control effect of d-limonene, and the LC50 of d-limonene, mixture (L+B) and mixture (L+F) were decreased by 32.6%, 38.4% and 33.1%. These results indicated that specific volatiles could directly bind to target genes and therefore enhance the control effect of B. tabaci.
