“…Field populations represent regions with the greatest crop production of apple and peach in Brazil and the orchards were selected based on records of control failure reported by technicians and growers. Larvae were collected from the field during the 2010 to 2012 apple-growing season and reared in the laboratory on an artificial diet according to the procedures described in ARIOLI et al (2010). For each collected population, neonate larvae (0-24 h old, generation F2) were exposed to a diagnostic concentration (based on the values of LC 99 ) of insecticide defined in the joint analysis of the baseline susceptibility data.…”

“…For insecticides susceptibility characterization, we used a reference susceptible population (population of Laboratory) of G. molesta that has been maintained in the laboratory, free from selection pressure by insecticides, for 10 years, reared in the an artificial diet (ARIOLI et al, 2010). To validate the candidate diagnostic insecticide concentrations, we collected larvae from 13 G. molesta populations from orchards located in different municipalities of the state of Rio Grande do Sul, Santa Catarina and São Paulo, Brazil (Table 1).…”

“…For the bioassays, we used the artificial diet proposed by ARIOLI et al (2010), commonly used for rearing G. molesta. After preparation, the artificial diet was kept in bath regulated at 50ºC and, posteriorly, 1.25mL were transferred to 24-well acrylic plates (COSTAR™).…”

“…The control of G. molesta in Brazil has been carried out mainly using organophosphorate insecticides (chlorpyrifos and phosmet) and insect growth regulators (lufenuron and novaluron) (ARIOLI et al, 2010). However, new insecticides (chlorantraniliprole and spinetoram) have been introduced in the Brazilian market for G. molesta management (CHAVES et al, 2014).…”

“…Resistance evolution is a serious threat for the chemical control sustainability of the oriental fruit moth when we consider the high insecticide selection pressure in Brazil (6-8 treatments per season) (BOTTON et al, 2011), its polyphagy (preference for apple and peach) and its high reproductive ability Silva et al (6 generations per year) (ARIOLI et al, 2010). These aspects are an alert for the risk of resistance evolution of G. molesta to insecticides in Brazilian orchards production systems.…”

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 (metaflumizone), 1.2 (chlorantraniliprole), 4.8 (novaluron), 5.1 (tebufenozide), 11.3 (phosmet) and 222.5 (pyriproxyfen). Based on the LC99 (µg a.i./cm2), the diagnostic concentrations of 0.6 (spinetoram), 5.5 (metaflumizone), 5.6 (chlorantraniliprole), 19.6 (tebufenozide), 37.4 (phosmet), 37.8 (novaluron) and 2011 pyriproxyfen) caused high mortality (>95%) of neonates from field populations. These diagnostic concentrations will be used in resistance monitoring programs of G. molesta in Brazil.

Grapholita molesta (Busck) is one of the main pests of apple trees, and lives on their shoots and fruits. In southern Brazil, the insect is also found on old branches and structures similar to aerial roots, so-called burrknots. This study evaluated the development and population growth potential of G. molesta fed on burrknots, compared with apple fruit cultivar. Fuji and a corn-based artiÞcial diet. The study was carried out in the laboratory under controlled temperature (25 Ϯ 1ЊC), relative humidity (70 Ϯ 10%), and photophase (16 h). The biological parameters of the immature and adult stages were determined, and a fertility life table was constructed. Insects fed on burrknots showed a longer duration and a lower survival for the egg-to-adult period (29.3 d and 22.5%) compared with those that fed on apples (25.1 d and 30.0%) and artiÞcial diet (23.9 d and 54.8%). Insects reared on aerial roots had a lower pupal weight (10.0 mg) compared with those reared on either artiÞcial diet (13.7 mg) or apple cultivar. Fuji (12.4 mg). The fecundity and longevity of males and females did not signiÞcantly differ for the three foods. Based on the fertility life table, insects reared on burrknots had the lowest net reproductive rate (Ro), intrinsic rate of population growth (r m ) and Þnite rate of increase (), compared with insects reared on artiÞcial diet and apple fruit. Burrknots support the development of the complete cycle of G. molesta, which allows populations of this pest to increase in orchards.

Oriental fruit moth, Grapholita molesta Busck (Lepidoptera: Tortricidae) is an important fruit pest with a wide range of host in many fruit producing countries. This study was conducted with the purpose of determining the adult population development of G. molesta on different fruit species in different locations in Çanakkale province of Turkey. With this purpose pheromone traps were placed in peach, cherry and apricot orchards in Central, Biga, Lapseki and Bayramiç districts of Çanakkale province. The traps were checked weekly and the number of adult G. molesta in traps were recorded. At the end of the study, the pest is confirmed to exist in all fruit producing areas of Çanakkale province. First adult emergence was at early May with the adult population continuing until October. The pest has 2-3 generations throughout production season, which may change with relation to fruit species and location. According to the statistical analysis of the data, both location and fruit species have significant effects on adult population development of the pest with the highest population occuring in peach as the fruit species and Lapseki disrict as the location. It is thought that, the differences in adult population density and development between orchards with the same fruit species is caused by different fruit cultivars used in orchards, different treatments by farmers and climate differences.
