Silverleaf whitefly (SLW) (Bemisia argentifolii Bellows and Perring) feeding on tomato (Lycopersicon esculentum Mill.) plants induces a disorder in thefruitknown as irregular ripening. The effects of silverleaf whitefly feeding on ripening of tomatofruitboth attached to and detached from the plant are described. ‘Florida Petite’ tomatoes free of SLW, attached to the plant, began an ethylene climacteric between 40 and 45 days after anthesis (DAA), coincident with a rapid increase in red color and loss of firmness. The ethylene climacteric began between 45 and 50 DAA in tomatofruitfrom plants infested with SLW, and thefruitdeveloped less red color and softened less than didfruitfrom plants free of SLW.Fruitharvested 45 DAA from plants free of SLW reached the respiratory and ethylene climacteric peak 3 days after harvest, developed normal red color, and softened similar tofruitripened on the plant. In contrast, fruitharvested 45, 50 or 55 DAA from SLW-infested plants showed no respiratory or ethylene climacteric, had poor color development, and did not soften to the same extent as didfruitfrom plants free of SLW.
