This research was carried out in a citrus nursery of orange 'Valência' to study the effect of products to control the citrus leafminer, Phyllocnistis citrella. The products (active ingredient) and amounts of commercial product/100 I water, were: imidachloprid (150 g), Bacillus thuringiensis (200 g), lufenuron (75 ml), abamectin + mineral oil (25 ml + 250 ml), fention (100 ml), and a check. The statistical design was a randomized block, with six treatments and four replications. Each treatment consisted of 20 plants (five in each block), and 10 leaves per plant were collected. The treatments were evaluated 7 and 14 days afta product application. The most efficient products were: imidachloprid, lufenuron and abamectin + mineral oil; Bacillus thuringiensis presented moderate control and fention was not efficient.
