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.
Smith & Giurcanu (in press) found that an insecticide containing bifenthrin and zeta-cypermethrin (Hero[R], FMC Corporation, Philadelphia PA) suppressed transmission of TYLCV in greenhouse studies on a level similar to flupyridifurone in tomato that were exposed to viruliferous whitefly 3 and 7 days after treatment.
Our results and those published in the literature have not found any onion cultivar to be resistant to IYSV, nor any onion cultivar to be free of the virus after exposing many cultivars to viruliferous
TYLCV C3 primers only produced the expected ~200 base pair PCR product in healthy tomato exposed to viruliferous
Further, insecticidal control of the viruliferous
adults proved ineffective in preventing primary spread of Tomato spotted wilt virus (Momol et al.
First, because western flower thrips can reproduce on many different plants, viruliferous
adults arise from many different sources.
whiteflies were maintained on American cotton, Gossypium hirsutum.
