| Trichogramma spp. (Hymenoptera: Trichogrammatidae) can control Diaphania hyalinata Linnaeus (Lepidoptera: Pyralidae). On the other hand, pesticides may reduce the efficiency of natural enemies. The objective was to evaluate the side-effects of fungicides used in the production of cucurbitaceous crops on Trichogramma atopovirilia Oatman & Platner parasitizing D. hyalinata eggs. The fungicides used in bioassays were: azoxystrobin (0.08 g active ingredient [ai] L-1), chlorothalonil (2.00 g ai L-1), mancozeb (1.60 g ai L-1), tebuconazole (0.25 g ai L-1) and thiophanate-methyl (0.49 g ai L-1). Cardboards with 30 D. hyalinata eggs previously immersedin fungicide solutions and distilled water (control) were offered separately to 20 newly emerged T.... |
