The suggested proximate mechanism underlying decision-making in male <i>A. tabida</i>.

<p>While mating a virgin female increases the tendency to stay on the patch, consequently increasing patch residence time, re-mating an already mated female has no impact on the residence time.</p

Estimated regression coefficients (<i>β</i>) and hazard ratios (exp (<i>β</i>)) for covariates of the Cox model on the patch-leaving tendency of males <i>A. tabida</i> in a patch of females.

The main motivation-based mechanisms of decision-making described for female parasitoids.

<p>In the incremental mechanism, motivation level increases with an oviposition while in the decremental mechanism, motivation level decreases with an oviposition, leading to a shorter patch residence time with the latter. In both cases, the organism leaves the patch when its motivation level reaches a threshold.</p
