Abstract A semi-field method was developed to evaluate the effects of pesticides on the hoverfly Episyrphus balteatus (Diptera, Syrphidae). The effects of deltamethrin and phosalone were tested on 2 to 3-day-old larvae, on young potato and broad bean plants. Trials were carried out indoors at 20 deg C and outdoors under cover. The analytical quantification of pesticide residues using chromatographic analysis was an original component of this work which required the collaboration of biologists and chemists. The results suggest that in these experimental conditions the larvae are exposed to less residue than in laboratory trials with larvae confined in Petri dishes or other small arenas.
