| Flight dispersal enables aphids not only to locate suitable plants but disseminate obligate aphid-pathogenic fungi among hosts. To quantify postflight colonization and fecundity potential of pathogen-infected alates, several hundreds of Myzus persicae and Sitobion avenae alates were infected preflight by a common aphid pathogen Pandora neoaphidis, flown for 0.01-10.2 km in a flight mill system, and individually reared for their performance under laboratory conditions. Cumulative probabilities [P(m凾N)] for the counts of infected alates producing m nymphs per capita (m凾N) before they became mycosed and of those uninfected ones of each aphid species during the same period of colonization fit very well to the logistic model P(m凾N) =1/[1+exp(a+rm)] (r2刣0.98), yielding a solution to the probability of the alates with a specific fecundity, pm=P(m凾N) |
