When feeding on its host plant, both nymphs and adults can acquire viruses if the plant is already infected, then becoming viruliferous
. Even though nymphs can carry viruses inside their bodies, they are unable to disseminate them within important distances, so virus dispersal depends entirely on the adults, which are the mobile stage and also the responsible for selection and colonization of the host plant (Byrne & Bellows, 1991).

whitefly and resistance.
whiteflies were then transferred to 8-10 days old ridge gourd seedlings for IAP of 30 min, 1,6,12 and 24 hr at the rate of 10 per seedling.
Our efforts to compare the efficacy of atplant treatments when plants were exposed to viruliferous
whiteflies at planting versus 2 weeks after planting by protecting plots with row covers met with limited success because virus pressure was very low in the spring trial and the row cover treatment failed in the fall 2013.
For greenhouse evaluation of MSV resistance, 10 seeds were planted and seedlings were thinned to 8 per pot just before infestation with viruliferous
The third set of data concerns the presence or absence of the virus disease Potato virus Y (PVY) (pepper strain, 0 pathotype) on pepper plants Capsicum annuum, spread by viruliferous

behavior for viruses (Jha et al., 2010).
A bulk of Pop 63 SR was planted at IITA, Ibadan (7[degrees]38' N, 3[degrees]93' E), Nigeria and [S.sub.0] plants were infested with viruliferous
leaf hoppers (Cicadulina spp.) about 9 d after planting.
