Interplay of Cucurbit Yellow Stunting Disorder Virus With Cucurbit Chlorotic Yellows Virus and Transmission Dynamics by <i>Bemisia tabaci</i> MED

Cucurbit chlorotic yellows virus (CCYV) and cucurbit yellow stunting disorder (CYSDV) are two closely related criniviruses that often coinfect cucurbits associated with disease. Both viruses distributed worldwide transmitted in a semipersistent manner by the whitefly vectors Bemisia tabaci MED or MEAM1. The major goal of this study was to provide insight into interaction CCYV CYSDV cucumber effect on transmission B. MED. titers both were estimated single- dually infected plants via reverse transcription PCR assays. In mixed infections, accumulation significantly decreased. When adults placed viruses, their simultaneous efficiency higher, whereas each individual low. Moreover, nonviruliferous whiteflies preferentially settled crinivirus-infected plants, viruliferous attracted healthy plants. Finally, titer calculated five commercial hybrids, followed subsequent experiments. Our results show although lower infections cucumbers, increased.
