"Spatial , temporal and individual parasitoid responses to heterogeneous environment relevant to biological control"@en . "We will analyze spatial, temporal and individual components of interactions between the aphid parasitoid Aphidus colemani Viereck and its host, green peach aphid, Myzus persicae Sulzer, on pepper plants. The problems we address are: (1) which types of spatial distribution of host mortality are in the field; (2) when is the temporal component of host regulation in the field a property of an ensemble rather than a result of stabilizing mechanisms occurring within a local population; (3) which is the influence of individual variability on parasitoid life history characteristics and sex allocation; (4) which are the possible practical consequences of individual variability? The problems solved are vital for elucidating of basic stabilizing mechanisms of natural populations and for improving success rates of biological control programmes."@en . . . . . . . .
