Abstract

Polyphagous natural enemies can mediate a variety of indirect interactions between resource populations. Such indirect interactions are often reciprocally negative (i.e. apparent competition), but the sign of effects between resource populations can be any combination of positive (+), negative (-), or neutral (0). In this article we focus on parasitoids to illustrate the importance of natural enemy-mediated indirect interactions in predicting risk and efficacy in biological control. We review recent findings to illustrate how an improved understanding of parasitoid behavioral ecology may increase model accuracy.

摘要

多食性天敌可以介导资源种群之间的多种间接相互作用。这种间接相互作用通常是相互负面的（即明显竞争），但资源种群之间的效应的符号可以是正 (+)、负 (-) 或中性 (0) 的任意组合。在本文中，我们专注于寄生蜂来举例说明天敌介导的间接相互作用在预测生物防治中的风险和效果方面的重要性。我们回顾了最近的发现，以说明对寄生蜂行为生态学的更好理解如何提高模型的准确性。
