Age and multiple mating effects on reproductive success of Grapholita molesta (Busck) (Lepidoptera, Tortricidae) Rev. Bras. entomol.
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...

Assessment of SPLAT formulations to control Grapholita molesta (Lepidoptera:Tortricidae) in a Brazilian apple orchard. Repositório Alice
ARIOLI, C. J.; PASTORI, P. L.; BOTTON, M.; GARCIA, M. S.; BORGES, R.; MAFRA-NETO, A..
Mating disruption is a technique that uses synthetic copies of sex pheromones to control insect pests. We aimed to control Oriental fruit moth (OFM) Grapholita molesta (Busck) (Lepidoptera: Tortricidae) with formulations of SPLAT Grafo (SG) and SPLAT Grafo Attract and Kill (SGAK) in small (1 ha) apple (Malus domestica Borkh.) orchards. Our experiment was conducted in a commercial orchard with Gala trees (spacing 1.5 × 4.5 m) in Vacaria, Rio Grande do Sul State, Brazil. We evaluated the effect of four treatments on G. molesta population densities: a) SG at 1 kg ha-1 (300 point sources of 3.3 g each), b) SGAK at 1 kg ha-1 (1000 point sources of 1 g each), c) insecticides as recommended by Integrated Apple Production (IAP), and d) untreated control (no...

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...

Mating disruption with low density diffusers for the management of oriental fruit moths (Lepidoptera: Tortricidae) in apple orchards under subtropical climate in southern Brazil Rev. Bras. Frutic.
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 Anais da SEB
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.

Oviposition behavior of Grapholita molesta Busck (Lepidoptera: Tortricidae) at different temperatures Neotropical Entomology
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...

Susceptibility of Grapholita molesta to insecticides in Brazil. Repositório Alice
BATISTA NETO, O. A.; BOTTON, M.; BERNARDI, D.; ARIOLI, C. J.; OMOTO, C..
ABSTRACT: The use of insecticides has been the main tool for Grapholita molesta (Busck) control in Brazil, which is considered one of the most important pests in apple and peach orchards. In order to implement an Insect Resistance Management (IRM) program, studies were conducted to characterize the baseline susceptibility of G. molesta to major insecticides for its control. Then, we conducted an insecticide susceptibility monitoring in thirteen field-collected populations of the pest. Neonates (0-24h old) were exposed to insecticides applied on surface of artificial diet. A high susceptibility was verified when neonates of the Laboratory population of G. molesta were exposed to insecticides with LC50 values (μg a.i./cm2) of 0.1 (spinetoram), 1.0...

Studying the susceptibility of peach trees to Grapholita molesta (Busck) is one of the major steps in the develop- ment of pest-resistant peach varieties. This work evaluated the susceptibility of 55 genotypes of the ? Prunus Rootstock Collection? (?Coleção Porta-enxerto de Prunus ?) of Embrapa Temperate Climate (Pelotas, Rio Grande do Sul, Brazil) to the natural infestation of G. molesta , assessed the oviposition preference of G. molesta in choice and no-choice bioassays, and estimated the biological parameters and the fertility life table on different Prunus spp. genotypes in the laboratory. Genotypes Prunus kansuensis (Rehder), I-67-52-9, and I-67-52-4 were the most susceptible to G. molesta infestation in the field ( > 60% of branches infested),...

Traps and baits for luring grapholita molesta (Busck) adults in mating disruption-treated apple orchards. Repositório Alice
PADILHA, A. C.; ARIOLI, C. J.; BOFF, M. I. C.; BOTTON, M..
Grapholita molesta (Busck) is one of the main pests in apple crops in Brazil, where it is controlled by mating disruption (MD) with the use of the synthetic sex pheromone. However, sex-pheromone-based monitoring is not effective in MD-treated areas and may result in losses in production. This work has defined a trap model and a bait for luring G. molesta adults in MD apple orchards. The experiments were conducted in commercial apple orchards located in São Joaquim, SC, Brazil. Three trap models " McPhail, Pot, and Ajar " and three baits " grape juice (25%) (GJ), sugarcane molasses (25%) (SM), and a solution containing brown sugar (8.69%) and terpinyl acetate (0.05%) (TAS) " were assessed for lur- ing G. molesta adults in areas subjected to the mating...
