“…Treatments 1 (0.0 m), 2 (0.40 m), 3 (0.80 m), 5 (1.60 m) and 6 (2.00 m) had low captures due to the flight height of these insects. The fly trap height had also been reported as a factor that affects the number of captured insects in persimmon trees (BAVARESCO et al, 2005) and cabbages (MICHEREFF et al (2000). Moreover, Teixeira et al (2008) evaluated the capture of M. domestica with traps installed at 1.00 m of height from the ground, due to the flight height of these flies.…”

The insect Cochliomyia hominivorax (Diptera: Caliphoridae) causes primary cutaneous myiasis, and the use of traps is an alternative to monitor this fly in the field. Thus, the objective of this work was to develop a low-cost trap for collecting C. hominivorax in the field. Three experiments were conducted, with six replications, in the experimental field of the Brazilian Agricultural Research Corporation (Embrapa -Agropecuária Oeste), in Ponta Porã, State of Mato Grosso do Sul, Brazil. Traps were developed using two-liter polyethylene terephthalate (PET) bottles cut in half, with 30 grams of bovine liver and water covering 90 % of the liver mass placed in the bottom half, using the upper half as a cover funnel to keep the captured flies in the bottom half. The experiments consisted of evaluations of different opening diameter of the trap entrance (3, 4, 6 and 7 mm) with traps installed at 1.16 m from the ground (Experiment 1), heights of installation of the traps (0.00, 0.40, 0.80, 1.20, 1.60 and 2.00 m from the ground) (Experiment 2) and bottle colors (yellow, blue, white, green, red and transparent) (Experiment 3). The collected data were subjected to Tukey's test (p < 0.05). The ideal traps for collecting C. hominivorax in the field were those with opening diameter of 6 mm, height installation of 1.20 m from the ground, using transparent PET bottles.

“…Por apresentar aberturas em todas as direções, favorece a formação da pluma do feromônio (Cardé & Elkinton 1984), resultando em maior atração dos machos. De acordo com Michereff et al (2000), devido ao conjunto de anteparos típicos de armadilhas aladas, o modelo Wing Trap também dificulta a saída dos insetos atraídos pelo feromônio, favorecendo a sua captura na superfície adesiva.…”

“…Não foram observadas diferenças significativas (F = 1,40; gl = 4, 95; P > 0,05) entre as alturas de posicionamento das armadilhas no intervalo de 0,5 a 2,5 m (Tabela 2). Embora este fator possa interferir na eficiência das armadilhas iscadas com feromônio sexual (Aliniazee 1983, Ahmad 1987, Bhardwaj & Chander 1992, Michereff et al 2000 sendo considerado de fundamental importância para o sucesso na captura de insetos (Cardé & Elkinton 1984, Vilela & Della Lucia 1987, informações de outros países sugerem que para G. molesta, as mesmas devem ser dispostas entre 1 a 4 m acima do nível do solo (Rothschild & Minks 1977, Rice et al 1982.…”

Monitoring of Grapholita molesta (Busck) (Lepidoptera: Tortricidae) on Peaches with Synthetic Sexual Pheromone ABSTRACT -Oriental fruit moth, Grapholita molesta (Busck), is one of the most important peach pests. In Brazil, two commercial formulations of sexual pheromone for oriental fruit moth are used in delta traps to monitor this pest in peach orchards. The traps are positioned at 1.6 to 1.8 m of height from the ground level with replacement of the lures every 6 weeks. However, this information was adapted from other countries and no local research was done to validate these recommendations. Therefore, we conducted field experiments to evaluated the influence of the format, coloration and position the traps baited with synthetic sexual pheromone of oriental fruit moth, as well as the effectiveness time of two commercial formulations [

This population monitoring in IPM could lead to fewer sprayings in comparison to conventional systems.…”

Diamides have been used worldwide to manage the diamondback moth (DBM), Plutella xylostella L. (Lepidoptera: Plutellidae), however some strains showed resistance to these molecules. Also, pheromone traps could be used to manage this pest, hence reducing the use of insecticides in the field. Resistant DBM strains may have biological disadvantages in comparison to susceptible strains in areas without sprays, including reduction in fitness or behavioral changes. Therefore, the aim of this study was to investigate whether DBM strains resistant to chlorantraniliprole showed adaptive costs that could alter male attraction to the sex pheromone, in comparison to susceptible strains in the laboratory and semi-field conditions. First, the LC1, LC10, LC25, and LC50 of DBM to chlorantraniliprole were established, which were 0.003, 0.005, 0.007, and 0.011 mg a.i. liter−1, and 5.88, 24.80, 57.22, and 144.87 mg a.i. liter−1 for the susceptible and resistant strains, respectively. Development and reproduction of DBM strains subjected to those concentrations were compared. Later, male response to the sex pheromone was investigated in a Y-tube in the laboratory and in a greenhouse to pheromone traps. Resistant DBM strain showed an adaptive cost in comparison to the susceptible strain that can result in a delay in population growth in the field when selection pressure is absent. Conversely, resistant males have no olfactory response alteration in comparison to susceptible males, consistently at 3 (P = 0.6848) and 7 days (P = 0.9140) after release, suggesting that pheromone traps continue to be a viable alternative to manage DBM in an IPM system.
