Longevity of white-backed planthopper ( Sogatella furcifera ) adults at 20°C , 25°C , and 28°C . Samples sizes at 20°C for the viruliferous, non-viruliferous, and control populations were 40, 2, and 28 individuals, respectively (F = 7.2, df = 2, P = 0.0018); at 25°C were 31, 34, and 38, respectively (F = 5.3, df = 2, P = 0.0065); and at 28°C were 41, 24, and 36, respectively (F = 3.7, df = 2, P = 0.0294). Values shown are means ± SE. Different letters above the columns indicate means that differ significantly at the P = 0.05 level by the SNK test.
