Factores involucrados en la respuesta del picudo del agave hacía el compuesto feromonal 2-metil-4-octanona y su manejo con agave fermentado e insecticidas sintéticos. Colegio de Postgraduados
Azuara Domínguez, Ausencio.
El picudo del agave Scyphophorus acupunctatus produce una feromona de agregación que atrae ambos sexos. Sin embargo, la respuesta es baja debido a diferentes factores que interfieren, por lo que es necesario un mejor conocimiento de los factores participantes, así mismo, buscar nuevas alternativas de control. En la presente investigación se plantearon los siguientes objetivos: 1) Determinar la participación del sexo, edad y de la estructura genética en la respuesta electrofisiológica y de comportamiento de búsqueda de S. acupunctatus al compuesto principal de su feromona de agregación. 2) Evaluar la eficiencia de la planta de agave tequilero en estado fermentado en el trampeo del picudo e identificar los compuestos volátiles atractivos para este insecto....

Behavioral and olfactory antennal responses of Solenopsis geminata (Fabricius) (Hymenoptera: Formicidae) workers to their dufour gland secretion Neotropical Entomology
Brindis,Yolanda; Lachaud,Jean P.; Gómez Y Gómez,Benigno; Rojas,Julio C.; Malo,Edi A.; Cruz-López,Leopoldo.
Behavioral and electrophysiological tests were performed to evaluate the responses of workers of the ant Solenopsis geminata (Fabricius) from different size categories to Dufour gland extracts. Morphometric measures based in head widths across eyes were used to determine worker sizes. Trail following response of different worker sizes to Dufour gland extract from workers of different sizes was assessed. For each worker size category olfactory responses to Dufour gland extracts were determined using electroantennography (EAG). Gas chromatography and mass spectrometry (GC-MS) were used to determine the chromatographic profile of Dufour gland secretion for each worker size. Morphometric measures permitted to classify the workers of S. geminata as large,...

Efeito de fatores endógenos na percepção química de Grapholita molesta(Busck) (Lepidoptera: Tortricidae) ao feromônio sexual Neotropical Entomology
Altafini,Deisi L; Sant'Ana,Josué; Redaelli,Luiza R.
The oriental fruit moth, Grapholita molesta (Busck), stands out as one of the most important pest in Rosaceae orchards in Brazil. During feeding, caterpillars bore into shoots, branches and fruits, impairing the commercial production. This work aimed to study the effect of endogenous factors in the chemical perception and in the species chemotactic behavior, seeking to optimize monitoring and the behavioral control of this pest. We evaluated male electroantennographical (EAG) and chemotactical (olfactometry) responses to the synthetic sex pheromone in different ages, virgins or mated and fed or unfed. The EAG responses of males did not differ for all evaluated factors. Nevertheless, the chemotactical behavior of males seems to decrease with age, not...

Identification and field evaluation of a new blend of the sex pheromone of Hypsipyla grandella PAB
Blassioli-Moraes,Maria Carolina; Borges,Miguel; Laumann,Raul Alberto; Borges,Rafael; Viana,Amanda Rodrigues; Thomazini,Marcílio José; Silva,Cleonor Cavalcante Alves; Oliveira,Márcio Wandré Morais de; Boff,Mari Ines Carissimi.
Abstract: The objective of this work was to identify and carry out a field testing of the sex pheromone composition of the mahogany shoot borer, Hypsipyla grandella, from a population in Southern Brazil. Abdominal glands of H. grandella females were excised and extracted using n-hexane; the gland extracts were analysed by gas chromatography (GC-FID and GC-MS). Wind-tunnel and electrophysiology experiments were conducted to evaluate the role of gland compounds in the mating behavior of H. grandella males. In the field, pheromone traps containing the identified pheromone were tested. In addition to the two previously identified compounds - (9Z,12E)-tetradecadien-1-ol and (9Z,12E)-tetradecadienyl acetate -, in insects from Central America populations, two...
