Potyvirus transmission is not increased by pre-acquisition fasting of aphids reared on artificial diet

Abstract: Aphids (Myzus persicae), fasted after removal from healthy rearing plants, transmitted tobacco etch potyvirus (TEV) more efficiently than unfasted aphids whether virus acquisition was from infected leaves or through membranes. There was no difference in uptake of lZSl-labelled TEV by fasted or unfasted aphids as measured by liquid scintillation counting. When aphids acquired lZSl-labelled TEV, label was retained in the stylets (as determined by autoradiographic light microscopy) by 51% of 272 fasted aphids, as… Show more

“…While a 1–2 hour starvation period for the aphid vectors has no influence on subsequent plant-to-plant transmission of CaMV [25], which we confirm here, transmission of TuMV and of potyviruses in general is increased significantly under these conditions [26], [27]. Here, we were not able to observe an impact of pre-acquisition fasting of aphids on transmission of TuMV.…”

“…MDMV has a short acquisition access period (AAP) of 10–30 s [ 58 ]. Aphid transmission of the virus is closely correlated to the retention of the virus in stylets [ 59 ]. Berger et al [ 60 ] also discovered that retention of MDMV was much longer when increasing the time of acquisition time.…”

“…Some cultural control measures were reported to have positive results in affecting aphid flight thereby contributing towards a reduction in the spread of non-persistently transmitted viruses. These include reflective surfaces of aluminum foil (Smith et al 1964), weed removal (Duffus 1971), insect repellents (Gibson et al 1982), intercropping with a nonsusceptible crop (Thresh 1982), conventional insecticides mixed with mineral oils (Gibson and Rice 1986;Wang and Pirone 1996;Fereres 2000), floating row covers (Avilla et al 1997), UV-absorbing plastics (Antignus 2000) and the use of barrier crops as border plants (Fereres 2000). Nevertheless, no evidence has been reported regarding the effectiveness of any of the measures to control the transmission of potyviruses.…”
