| identification of mealybug pest species (hemiptera: pseudococcidae) in egypt and france, using a dna barcoding approach. | pseudococcidae (mealybugs) is a large taxonomic group, including a number of agronomic pests. taxonomic identification of mealybug species is a recurrent problem and represents a major barrier to the establishment of adequate pest management strategies. we combined molecular analysis of three dna markers (28s-d2, cytochrome oxidase i and internal transcribed spacer 2) with morphological examination, for the identification of 176 specimens collected from 40 mealybug populations infesting various ... | 2012 | 22360997 |
| molecular and morphological identification of mealybug species (hemiptera: pseudococcidae) in brazilian vineyards. | mealybugs (hemiptera: pseudococcidae) are pests constraining the international trade of brazilian table grapes. they damage grapes by transmitting viruses and toxins, causing defoliation, chlorosis, and vigor losses and favoring the development of sooty mold. difficulties in mealybug identification remain an obstacle to the adequate management of these pests. in this study, our primary aim was to identify the principal mealybug species infesting the major table grape-producing regions in brazil, ... | 2014 | 25062012 |
