Efeito de fatores endógenos na percepção química de Grapholita molesta(Busck) (Lepidoptera: Tortricidae) ao feromônio sexual
Provedor de dados: 82
Autores: 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...

Oviposition behavior of Grapholita molesta Busck (Lepidoptera: Tortricidae) at different temperatures
Provedor de dados: 82
Autores: Silva,EDB da; Kuhn,TMA; Monteiro,LB.
Cultivation of temperate-climate fruits is economically important for Brazil. Grapholita molesta Busck is a pest that causes damage to apples, peaches, plums, and pears growing in different micro-regions of southern Brazil, and understanding its reproductive behavior is essential to develop control strategies. The objective of this study was to ascertain the influence of different temperatures (13, 16, 19, 22, and 25ºC) on the oviposition behavior of G. molesta. Females of G. molesta were placed in individual plastic containers, and the pre-oviposition period and the number of eggs laid were assessed until adult death. Temperature influenced the pre-oviposition period, and females kept at 22º were the first to lay their eggs. Oviposition occurred over a...

Age and multiple mating effects on reproductive success of Grapholita molesta (Busck) (Lepidoptera, Tortricidae)
Provedor de dados: 92
Autores: Morais,Rosana M. de; Redaelli,Luiza R.; Sant'Ana,Josué.
The reproductive success of the oriental peach moth was evaluated in four experiments: 1) assessment of the mating duration, fecundity, fertility and longevity of females paired with virgin and immediately mated males; 2) mating duration, spermatophore size, fecundity, fertility and longevity in females paired with virgin and up to four times mated males; 3) receptivity of females to additional copulations after mating with virgin or mated males, and the effects of this behavior in female fecundity, fertility and longevity; 4) influence of insects age in the reproductive output. Males (33%) could copulate immediately after a previous copula. They were fertile until the fourth mating, but only in the first copula they transferred the longest (1.43 ± 0.10...

Mating disruption with low density diffusers for the management of oriental fruit moths (Lepidoptera: Tortricidae) in apple orchards under subtropical climate in southern Brazil
Provedor de dados: 94
Autores: Monteiro,Lino Bittencourt; Souza,Alexander; Argenton,Jeferson.
The oriental fruit moth, Grapholita molesta Busck, and fruit flies, Anastrepha fraterculus L., are the important apple pests under Subtropical climate in Southern Brazil, and control is normally accomplished with insecticides. An alternative strategy for the control of G. molesta is mating disruption, through the use of pheromones. Mating disruption strategies using a low density of dispensers (20) per hectare were tested in comparison with conventional pesticides for control of G. molesta in commercial Gala apple orchards in Fraiburgo, SC, for a period of five years. The average field efficiency period of mating disruption formulation over five years was 113 days. In this period the mating interruption index on mating disruption plots was 84.8% over five...

Ocorrência e danos de Grapholita molesta (Busck) (Lepidoptera: Tortricidae) em pessegueiros no município de Caldas, MG
Provedor de dados: 44
Autores: Souza,Brígida; Santa-Cecília,Lenira V.C.; Sousa,Luís O.V. de.
This work was carried out to evaluate the damages caused by Grapholita molesta (Busck) in twigs and fruits of peach trees (Prunus persicae) in Caldas, MG, during the growing seasons of 1995/96 and 1996/97. Fruits and twigs from three branches of fifteen plants were examined every 15 days. A great variation in the percentage of twigs damage was obtained throughout each season, especially in the second year, when a peak was observed in the end of January. The averages of the porcentage of damage were estimated in 22,9% and 19,4% in 1995/96 and 1996/97, respectively. The total incidence in fruits was 28,1% during the first year and 21,6% during the second year with peaks well definided in the end of October and beginning of November of 1995/96.
