Descripción
Lettuce crops, Lactuca sativa, organically produced in La Plata, Argentina, were sampled in order to determine the prevalence of fungal diseased aphids. Nasonovia ribisnigri was the only aphid detected and its occurrence was highly variable. The fungal pathogen Pandora neoaphidis (Entomophthoromycotina: Entomophthorales) was the only pathogen detected. We recorded a maximum of 34.2 aphids per plant and the highest rate of fungal prevalence was 56.6% (n = 30) (aphids infected/total aphids). Infected aphids were observed in all sampling sites. No differences of infection rates were detected between the center and the edge of crops. Host density was an important factor determining infection. The majority of host population was comprised of nymphs which were the most infected in terms of individuals per habitat unit (lettuce plant), but considering the proportion of infected aphids per stage of development, the prevalence of infection in nymphs and adults was similar.
