Plant Viruses Transmitted in Two Different Modes Produce Differing Effects on Small RNA-Mediated Processes in Their Aphid Vector

open access: yesPhytobiomes Journal, 2019
Transmission of plant viruses by aphids involves multitrophic interactions among host plants, aphid vectors, and plant viruses. Here, we used small RNA (sRNA) sequencing to visualize the sRNA response of Myzus persicae to two plant viruses that M ...

ECONOMIC ANALYSIS OF USING A BORDER TREATMENT FOR REDUCING ORGANOPHOSPHATE USE IN SEED POTATO PRODUCTION [PDF]

open access: yes
Recent research shows initial colonization of potato fields by winged green peach aphid is concentrated at field edges. This suggests that insecticides applied only to field margins during initial colonization would largely eliminate a colonizing aphid ...
