Abstract:
The toxicity of the fungicides captan, dodine, mancozeb, metiram and myclobutanil to adults, nymphs and 0–24 h eggs of Amblyseius fallacis was evaluated in the laboratory. Dodine and mancozeb reduced egg hatch significantly in comparison with water controls and dodine was the most toxic to the nymphs. Captan and metiram had no effect and the remaining fungicides were of intermediate toxicity. None of the fungicides affected the longevity and the fecundity of young females.
