Utilização de Armadilha tipo Pet para Captura de Insetos-Praga na Cultura do Maracujá

Passionflower (Passiflora spp.) hosts a great diversity of insects. Some species can cause injuries that can cause economic damage, reduce fruit production, and even lead to death. The objective of this work was to monitor the main pests of passion fruit through the use of different colored traps.The work was carried out in the field of the Experimental Farm of the Federal Rural University of Amazonia (UFRA) in March 2017. The PET traps were used to carry out the catches, with two different colors (white and green).10598 individuals were captured, and 5 orders were identified; Hymenoptera, Lepidoptera, Coleoptera, Diptera and Hemiptera. The order that showed the greatest abundance was Hymenoptera with 9719 individuals.The Formicidae family presented a great population richness in the two replicates, while in the second repetition (B2 and V2) it was observed a higher population density peak in the family Apidae. The distribution of the most frequent species in the collection intervals indicates a population richness of 137 individuals for bee (T. spinipes) on the second day of collection in trap V2. As for fruit fly (C.capitata and A. pseudoparallela), which are also pests that cause many economic losses for passion fruit producers, the reverse occurred, the greatest wealth found was on the second day of collection in trap B2.These results demonstrated that the new trap model is efficient in catching insects, suggesting a further useful destination for these packages.
