Vector relationship of Graminella nigrifrons to maize dwarf virus.
In laboratory colonies where the ratio of males to female was normally 2:1, 34-35% of adult Graminella migrifrons trynsmitted maize chlorotic dwary virus (MCDV). There was a statistically significant difference between the rate of MCDV transmission by female (46%) and that by males (29%). After that they began to reacquire the virus from the same test plants. This transmission data from tests involving transziers at intervals of more than 3 days may suggested that MCDV is being transmitted by G. nigrifrons in a persistent manner. In reality, all aspects of the transmission process reveal a realtionship between MCDV and G. nigrifrons that is not persistent and is best described as transient or transitory.
