[Laboratory and field tests about the transmission of Erysimum latent virus by Phyllotreata species (Chrsomelidae) (author's transl)].
Erysimum latent virus (ELV) proved to be transmissible by Phyllotreta atra, P. nemorum, P. nigripes, and P. undulata. From them P. nemorum is a new discovered vector. The acquisition of the virus by the beetles was possible within a feeding time of less than 10 minutes. Because virus transmission could be performed within 30 to 60 minutes immediately after virus uptake there exists apparently no latent period in the vector. The retention or persistence of ELV in the Phyllotreta species amounted up to 3 days. Trials to induce infectivity of Phyllotreta species by injection of the virus were unsuccessful. ELV was transmissible by Aphis frangulae gossypii, Brevicoryne brassicae, and Myzus persicae neither in short nor in long feeding times. Field tests showed that the Phyllotreta species are able to spread ELV under natural conditions.
