Encarsia tricolor Forster (Hym., Aphelinidae) is a facultative autoparasitoid that develops also on the important pest Aleyrodes proletella L. (Hom., Aleyrodidae) in cabbage (Brassica oleracea) in the field. The present laboratory research dealt with development, longevity and parasitization of the white fly parasitoid, E. tricolor at different temperatures in order to collect information for using it against A. proletella in biological control programmes. The results showed that mean duration… 
The cabbage whitefly, aleyrodes Proletella: causes of outbreaks and potential solutions
TLDR
The cabbage whitefly, A. proletella, has in recent years become a primary pest of several brassica crops in Europe, where nymphs, wax deposits and sooty mould caused by honeydew excretion reduce the marketable portion of the crop, particularly later in the year.
Natural enemies associated with the cabbage whitefly Aleyrodes proletella in Germany
TLDR
A 3-year survey of the natural enemies of A. proletella was conducted at five locations across Germany and the only whitefly specialist among the predators was Clitostethus arcuatus Rossi (Coleoptera: Coccinellidae).
Hyperparasitism behaviour of the autoparasitoid Encarsia tricolor on two secondary host species
TLDR
The window of vulnerability, i.e., the duration of the period in which a secondary host is susceptible to hyperparasitism, was largely determined by the occurrence and rate of melanization after the onset of pupation, as well as the effect of autoparasitoids on biological control programs and the consequences for selection and release of an effective, yet ecologically safe agent are discussed.
