Zoophytophagous predator sex pheromone and visual cues of opposing reflectance spectra lure predator and invasive prey.

ABSTRACT:

Introduction

In sub-Saharan Africa, the invasive South American leafminer Phthorimaea absoluta is the most damaging tomato pest. Females of the pest can reproduce both sexually and through parthenogenesis and lay their eggs on all tomato plant parts. The mirid predator Nesidiocoris tenuis, a biological control agent for the pest, is also a tomato pest when prey population is low. To date, however, no study has developed an eco-friendly solution that targets both the predator and its host in a tomato farming system.

Objective

To develop a bio-based management system for both pest and predator based on the combined use of sexual communication in the predator and visual cues.

Methods

We collected volatiles from both sexes of the Kenyan population of the predator N. tenui
