Winter prevalence of obligate aphid pathogen Pandora neoaphidis mycosis in the host Myzus persicae populations in southern China: modeling description and biocontrol implication

Abstract

Pandora neoaphidis overwintering had been investigated by monitoring its prevalence in Myzus persicaepopulations in open fields. Cabbage plants in field plots were weekly taken after mycosis initiation, to count and examine the living and dead aphids infected by P. neoaphidis. Based on the field data, infection levels (I) varied with field temperature (T), relative humidity (RH) and aphid count
