  abstract = {{B}iocontrol of exotic insect pests can be achieved by introducing natural enemies from the native range. {T}his method has been successful in controlling many pests worldwide, but negative effects on local non-targets have sometimes occurred. {B}efore the introduction of exotic macro-organisms useful for crop protection, a risk assessment is mandatory under {EU} regulations. {I}n this study, we assessed the non-target risks of the larval parasitoid {C}otesia typhae ({H}ymenoptera, {B}raconidae), a potential agent for inundative biocontrol of the {M}editerranean corn borer {S}esamia nonagrioides ({L}epidoptera, {N}octuidae), both natives to {S}ub-{S}aharan {A}frica. {T}he effects of {C}. typhae on 8 non-target species was determined by sequential analysis under laboratory conditions, including tests of acceptance, development monitoring, olfactory attractiveness and in planta parasitism test. {T}he results varied considerably between species. {B}y multiplying the probability of outcome of the successive steps of the parasitism process, we estimated that non-target species had lower average risks of {C}. typhae development (1 % of non-target larvae at risk) and of induced mortality (5 %) compared to {S}. nonagrioides larvae (41 and 42 % respectively). {T}he highest mortality risk in planta was observed for the cattail stemborer, {N}onagria typhae (9 %), although it was still lower than for the target species (33 %). {T}hese host range results and the low survival capacity of the parasitoid at winter temperatures, suggest a low long-term environmental risk, which is supported by the estimation of the global risk index proposed by van {L}enteren et al. (2003). {T}he host range and impact of {C}. typhae in field conditions will soon be determined.},
