Reduced Incidence of Lesser Peachtree Borer and Leucostoma Canker in Peach-Almond Hybrids

Influence of Prunus spp., peach cultivars, and bark damage on oviposition choices by the lesser peachtree borer (Lepidoptera: Sesiidae).

An examination of oviposition choices by the lesser peachtree borer, Synanthedon pictipes (Grote and Robinson) (Lepidoptera: Sesiidae), showed that wounded peach, Prunus persica (L.) Batsch, bark was attractive to females for oviposition. Females responded to bark that was injured mechanically (e.g., hammer blows, knife cuts, pruning wounds), infested by lesser peachtree borer larvae or injured...

BIOLOGICAL CONTROLÐMICROBIALS Susceptibility of the Lesser Peachtree Borer (Lepidoptera: Sesiidae) to Entomopathogenic Nematodes Under Laboratory Conditions

The lesser peachtreeborer, Synanthedonpictipes (Grote andRobinson), is an important pest of Prunus spp.We determined the susceptibility of S. pictipes to six entomopathogenic nematode species:Heterorhabditis bacteriophoraPoinar,H. indicaPoinar, Karunakar andDavid,H.marelatusLiu and Berry, Steinernema carpocapsae (Weiser), S. feltiae (Filipjev), and S. riobrave Cabanillas, Poinar and Raulston.

Genetic Variation of the Lesser Peach Tree Borer, Synanthedon pictipes (Lepidoptera: Sesiidae) in Arkansas

The lesser peach tree borer, Synanthedon pictipes (LPTB), belongs to the economically important Lepidopteran family Sesiidae. No studies on genetic variation or population structure on the genus Snyanthedon have been previously published. We examined DNA sequence variation in a 603 bp region of the mitochondrial cytochrome oxidase I gene (COI), tRNA-leu and cytochrome oxidase II gene (COII) fro...

Evolutionary Genomics of Peach and Almond Domestication

The domesticated almond [Prunus dulcis (L.) Batsch] and peach [P. persica (Mill.) D. A. Webb] originated on opposite sides of Asia and were independently domesticated ∼5000 yr ago. While interfertile, they possess alternate mating systems and differ in a number of morphological and physiological traits. Here, we evaluated patterns of genome-wide diversity in both almond and peach to better unde...
