|---|---|
| Predatory arthropods are commonly used as biological control agents (BCAs) released in commercial vegetable greenhouses as primary elements of the integrated pest management (IPM) programs for some of the most devastating pests on pepper and tomato in South Eastern Spain. Emamectin benzoate is a macrocyclic lactone insecticide derived from the avermectin family of natural products, which is being developed for the control of Lepidoptera pests on a variety of crops in Europe including vegetables. The compatibility of emamectin benzoate with the predatory BCAs, Amblyseius swirskii Athias-Henriot and Orius laevigatus (Fieber) in field trials (direct spray and aged residues), and Macrolophus pygmaeus (Rambur) and Chrysoperla carnea (Stephens) in semi-field studies was determined. RESULTS: Emamectin benzoate at the highest recommended rate (14.25 mg L-1) was compatible with A. swirskii and O. laevigatus when applied 3 d before the introduction of the arthropods, but toxic when directly sprayed, whereas M. pygmaeus and C. carnea adults survived to direct spray applications. CONCLUSIONS: Emamectin benzoate can be considered as a compatible (harmless) insecticide with A. swirskii and Orius laevigatus when applied 3 days before the predator introduction, and with M. pygmaeus and C. carnea in direct spray application. | |
