Evaluation Of Pierce’S Disease-Resistant Grapevine Cultivars In Upstate South Carolina, Annie Bruno

All Theses

Interest in wine grape production is increasing in South Carolina, but Pierce’s Disease (PD) caused by the xylem-limited bacteria Xylella fastidiosa (Xf) is a major limiting factor. Xf is spread by sap-sucking insect vectors in the Cicadellidae family such as sharpshooters. In the United States, Xf has become endemic to the southeast as global temperatures rise, causing winter temperatures to increase, which allows the bacteria to survive year-round. However, PD-resistant grapevine hybrid cultivars have become available through breeding V. vinifera genes with native American Vitis species that are resistant to Xf. In this study, the PD-resistant grapevine …

Feeding Behavior Of Sweet Potato Weevil, Cylas Formicarius (Fabricius) (Coleoptera: Brentidae) On Three Sweet Potato, Ipomoea Batatas L. Cultivars Grown In Tarlac, Philippines, Jerah Mystica Novenario, Flor Ceballo-Alcantara

The Philippine Agricultural Scientist

Sweet potato is grown in tropical countries for its edible tubers, which have become an essential food source. It is usually propagated through vine-cutting, which can be obtained from harvested plants or nurseries intended for cutting production only. The recurrent use of vines may cause increased weevil infestation. The crop is known to be infested with insect pests. More importantly, the sweet potato weevil, Cylas formicarius, targets the tubers, thus, causing the economic losses. Sweet potato farmers in Tarlac claim that only one sweet potato cultivar is being attacked by C. formicarius, however, it was found in this experiment that …

Taxonomy Of Cassava (Manihot Esculenta Crantz) Mealybugs (Hemiptera: Pseudococcidae) - 1: Identification And Local Distribution Of The Predominant Species On Witches’ Broom-Diseased Plants In The Philippines, Ireneo L. Lit Jr., Cristian Lucañas, Joanne Langres, Lolita Dolores, Ruby Ana Laude, Merdelyn Caasi-Lit

The Philippine Agricultural Scientist

Samples of cassava (Manihot esculenta Crantz) plants infected with witches’ broom disease were gathered from 13 provinces in the Philippines. Mealybugs were observed to occur in nine out of the 13 cumulative samples. The most predominant among several mealybug species observed was identified as Pseudococcus jackbeardsleyi Gimpel and Miller. P. jackbeardsleyi is not yet known to transmit phytoplasma, especially the one causing cassava witches’ broom (CWB). However, its occurrence in almost 70% of the CWB-infected samples provides circumstantial evidence that it may be related to the spread of the pathogen.
