The leafminer Tuta absoluta (Meyrick) is a major pest of the tomato crop and its development rate is known to decline when nitrogen availability for crop growth is limited. Because N limitation reduces plant primary metabolism but enhances secondary metabolism, one can infer that the slow larval development arises from lower leaf nutritive value and/or higher plant defence. As an attempt to stu...

Melon is one of the most exported fruits from Brazil. The leafminer fly, Liriomyza sativae (Blanchard) (Diptera: Agromyzidae), major problems that negatively interfere in productivity increase this crop. Chemical control adopted method for pest; however, producers have reported reduced susceptibility to insecticides. Thus, study aimed evaluate L. larvae abamectin, cyromazine, and cyantranilipro...

The objective of this work was to characterize the sexual behavior of the citrus leafminer, Phyllocnistis citrella Stainton, as the foundation for the isolation, identification, and synthesis of the complete sex pheromone of this species. Mating occurred in a time window of 2h, starting 1h before the onset of photophase. The large majority of tested insects mated in the first two days after eme...
