Abstract
In greenhouse expts. single adult grasshoppers (Melanoplus differentialis), were reared on young corn plants and starved 4-6 hrs. before feeding on tobacco plants infected with tobacco mosaic virus, potato virus X, or tobacco ringspot virus. Feeding time of 1-2 min. was allowed for transmission tests made immediately after the feeding, 15 min. feeding time for tests after 2 and 4 hr. waiting periods, and 30-min. feeding time for tests after 12 and 24 hr. waiting periods. 29.3% of 75 tested insects transmitted tobacco mosaic virus when tested immediately after feeding on the virus source. 46.6% of 15 insects tested after the 2 hr. waiting period transmitted the virus, likewise 29.4% of 34 tested after the 4 hr. waiting period, and 9.5% of 21 individuals tested after the 12 hr. waiting period. No transmission was observed with 58 insects following 24 hr. waiting period. 83.3% of 48 insects tested (waiting period not specified) transmitted the virus after being allowed a more extensive feeding on the test plant. 18% of 100 grasshoppers tested transmitted potato virus X to tobacco plants, and 6% of 100 insects tested transmitted tobacco ringspot virus to tobacco plants.Keywords
