none no species The success of foraging behavior of Microplitis wasps is governed by many factors including semiochemicals, experience and learning, as well as physiological state, rearing method etc. This paper summarizes the progress in the study on foraging behavior of Microplitis wasps. Its application in biological control is also discussed.
