| carposina sasakii (lepidoptera: carposinidae) in its native range consists of two sympatric cryptic lineages as revealed by mitochondrial coi gene sequences. | the genetic differentiation and genetic structure of the peach fruit moth, carposina sasakii matsumura (lepidoptera: carposinidae), was investigated in china, where the moth is native. the mitochondrial cytochrome c oxidase i (coi) gene of 180 individuals from 16 collections were sequenced and analyzed. the results showed that two sympatric and cryptic mtdna lineages existed within c. sasakii in china. the genetic differentiation has significant correlation with the geographical distance, but ha ... | 2015 | 26136498 |
| emergence of the overwintering generation of peach fruit moth (carposina sasakii) depends on diapause and spring soil temperatures. | survival rate and emergence timing of the overwintering generation of many temperate agricultural pests is expected to affect their population dynamics and damage potential. however the impact of fluctuating winter and spring conditions on the successful emergence of insects post-diapause is generally poorly known. here we characterize diapause responses in the peach fruit moth (pfm) pest, carposina sasakii matsumura, which overwinters at the larval stage in soil. temperatures at a depth of 5 cm ... | 2016 | 26724748 |
| development and characterization of novel microsatellite markers for the peach fruit moth carposina sasakii (lepidoptera: carposinidae) using next-generation sequencing. | the peach fruit moth carposina sasakii is an economically important pest on dozens of fruits from rosaceae and rhamnaceae in northeast asia. we developed novel microsatellite markers for c. sasakii from randomly sequenced regions of the genome using next-generation sequencing. in total, 95,153 microsatellite markers were isolated from 4.70 gb genomic sequences. thirty-five polymorphic markers were developed by assessing in 63 individuals from two geographical populations. the allele numbers rang ... | 2016 | 26999103 |
| warming accelerates carbohydrate consumption in the diapausing overwintering peach fruit moth carposina sasakii (lepidoptera: carposinidae). | climate warming provides a challenge for small insects persisting in cold seasons through diapause because they fail to accumulate and maintain adequate reserves to complete this stage successfully. one way of understanding this challenge is to follow physiological changes in these insects under higher temperatures, including the consumption and allocation of energy reserves during and after diapause. we simulated autumn and spring warming conditions to study carbohydrate consumption dynamics du ... | 2016 | 27426722 |
| sublethal concentration of beta-cypermethrin influences fecundity and mating behavior of carposina sasakii (lepidoptera: carposinidae) adults. | the purpose of this study was to evaluate the sublethal effects of the beta-cypermethrin on calling behavior and fecundity of a major fruit-boring pest of apple, carposina sasakii matsumura. the mating rate, fertility (total number of eggs laid per female), and adult longevity of adults were remarkably decreased as compared with that in control when the adults were exposed to 10% lethal concentrations (lc10) of beta-cypermethrin (lc10♀ × lc10♂), and the age-specific survival rate (lx) was also n ... | 2016 | 27498114 |
| morphological and ultrastructural characterization of carposina sasakii larvae (lepidoptera: carposinidae) infected by beauveria bassiana (ascomycota: hypocreales: clavicipitaceae). | the aim of this study was to better understand the pathogenesis of the entomopathogenic fungus beauveria bassiana (balsamo) strain tst05 observed on the peach fruit moth (carposina sasakii (matsumura)), an important orchard pest. the morphological and ultrastructural characterization of the mature larvae of c. sasakii infected by b. bassiana was investigated by using light, scanning and transmission electron microscopy. the results of the study show that b. bassiana tst05 infected the host larva ... | 2013 | 22940571 |
