Potential resistance of crape myrtle cultivars to flea beetle (Coleoptera: Chrysomelidae) and Japanese beetle (Coleoptera: Scarabaeidae) damage.
Field and laboratory studies were conducted to identify potential resistance among crape myrtles, Lagerstroemia spp., to Japanese beetle, Popillia japonica Newman and to flea beetles, Altica spp. Damage ratings revealed variation among cultivars in susceptibility to beetle feeding. Cultivars with Lagerstroemia fauriei Koehne in their parentage exhibited the least amount of damage in choice and ...
متن کاملInsights Into Flea Beetle (Coleoptera: Chrysomelidae: Galerucinae) Host Specificity From Concordant Mitochondrial and Nuclear DNA Phylogenies
Flea beetles in the genus Altica are herbivorous, urban agricultural pests that are morphologically difÞcult to distinguish. Host plant associations, therefore, have been used as an important species character in Þeld studies. Indigenous weeds in the Onagraceae, genus Oenothera, are known to serve as developmental hosts for the ßea beetle Altica litigata Fall. Although host plant speciÞcity in ...
متن کاملGenetic diversity of Lagerstroemia (Lythraceae) species assessed by simple sequence repeat markers.
Lagerstroemia (crape myrtle) are famous ornamental plants with large pyramidal racemes, long flower duration, and diverse colors. However, little is known about the genetic structure and diversity of germplasm in Lagerstroemia. We genotyped 81 L. indica cultivars, five other species of Lagerstroemia, and 10 interspecific hybrids using 30 simple sequence repeat markers; 275 alleles were gen...
متن کاملScreening of molecular markers linked to dwarf trait in crape myrtle by bulked segregant analysis.
Plant height is one of the most important traits of plant architecture as it modulates both economic and ornamental values. Crape myrtle (Lagerstroemia indica L.) is a popular ornamental woody plant because of its long-lasting mid-summer bloom, rich colors, and diversified plant architecture. These traits also make it an ideal model of woody species for genetic analysis of many ornamental trait...
متن کاملSusceptibility of brassicaceous plants to feeding by flea beetles, Phyllotreta spp. (Coleoptera: Chrysomelidae).
Crucifer-feeding flea beetles, Phyllotreta spp., are chronic insect pests in Canadian prairie canola production. Multiple laboratory and field feeding bioassays were conducted to determine the susceptibility of a wide range of crucifer species, cultivars, and accessions to feeding by flea beetles with the goal of discovering sources of resistant germplasm. In 62 bioassays of 218 entries, no con...
