Abstract:
Wheat or maize plants, infected with maize rough dwarf virus (MRDV), when exposed to 36 ° continue to develop the disease symptoms without any apparent heat-induced masking. However, the planthopper vector of this virus, Laodelphax striatellus (Fallén), is unable to transmit the virus normally under such heat conditions. High temperature is shown to affect mainly the phase of virus propagation within the vector's body. Nevertheless, the vector still has the possibility of overcoming the suppressive heat effect in spite of being exposed to 36 ° for the entire latent period of virus propagation in its body. This is attainable by continually feeding on an infected plant, thereby accumulating a sufficient amount of virus in the salivary glands through direct imbibition from the plant source where, contrary to the situation in the insect's body, virus multiplication is not suppressed by such temperature. © 1970.
