Interpretive Summary: Tomato yellow leaf curl virus (TYLCV), cucurbit leaf crumple virus (CuLCrV) and sida golden mosaic virus (SiGMV) are economically important whitefly-transmitted viruses infecting vegetable crops in Georgia and Florida. The MEAM1 whitefly predominates in the southeastern U.S. but recently the MED whitefly has also been detected in these states. Relative transmissibility of TYLCV, CuLCrV and SiGMV by these two whitefly types has a direct bearing on crop losses and management decisions. Our research showed that both the MEAM1 and MED whitefly efficiently transmitted TYLCV. However, only the MEAM1 whitefly transmitted CuLCrV and SiGMV. Knowledge of these differential transmission results for these three viruses will help growers, crop consultants, entomologists, virologists and regulatory scientists.

Technical Abstract: The Bemisia tabaci MEAM1 whitefly is the predominant cryptic species found in crop fields in Georgia and Florida. Recently, the B. tabaci MED whitefly cryptic species has also been detected in these states. Assessments of the relative transmission risks of the economically important whitefly-transmitted vegetable-infecting tomato yellow leaf curl virus (TYLCV), cucurbit leaf crumple virus (CuLCrV) and sida golden mosaic virus (SiGMV) by MEAM1 and MED whiteflies were made to evaluate potential crop losses and management options. The MEAM1 whitefly efficiently transmitted TYLCV, CuLCrV and SiGMV. However, the MED whitefly transmitted only TYLCV. Differential whitefly transmission of these viruses is important information for growers and crop consultants, and also entomologists, virologists and regulatory scientists.
