Abstract:      Based on the principle of ecological energetics, predatory insects depend completely on their prey to acquire energy. The energy ingested by predatory insects is therefore equivalent to the energy of their prey. According to the population energy dynamics of pest and predatory insects, the biological control of natural enemy insects can be quantitatively evaluated. In this paper, we discuss the principles of ecological energetics and calculation methods. We then use these methods to quantitatively evaluate the biological control value of predatory beetles in cotton agro-ecosystems. Ecological energetic analyses provide a new method to evaluate the biological control value of natural enemy insects in agro-ecosystems.
