1. Chitturi, Anitha. Thrips tabaci (Thysanoptera: Thripidae) and Iris yellow spot virus (genus: Tospovirus, family: Bunyaviridae) in onions: biology and transmission studies.

Degree: PhD, Entomology, 2010, University of Georgia

Thrips vectors of tospoviruses were surveyed in onions and other vegetable crops in India and in onions in Georgia, USA. The only known vector species of Iris yellow spot virus (IYSV) collected both in the USA and India was Thrips tabaci (Thysanoptera: Thripidae). In onions in Georgia, the two dominant species of thrips during this survey were Thrips tabaci and Frankliniella fusca. Competition studies between these two thrips species revealed that T. tabaci reproductively outcompeted F. fusca in onions. Distribution studies on T. tabaci in onions indicated that adult settling and oviposition are skewed towards the base of the plant. Field studies on the distribution of thrips and IYSV in onions demonstrated similar distributions of eggs and virus skewed towards the base of the plant. Transmission studies of IYSV indicate that T. tabaci can inoculate onion plants very efficiently, achieving 64% successful transmission in 15 minutes. Thrips tabaci appeared to be the main thrips vector of IYSV in both Georgia and India. Advisors/Committee Members: David Riley.

2. Skarlinsky, Thomas L. Interactions between Frankliniella Bispinosa (Morgan) and Frankliniella Cephalica (D. L. Crawford) in Florida.

Degree: MS, Entomology and Nematology, 2016, University of Florida

Frankliniella bispinosa (Morgan) and Frankliniella cephalica (D.L.Crawford) are morphologically similar species found on the flowers of Romerillo, Bidens alba (L.) DC. in Florida. The actual B. alba/flower thrips distribution in Florida is poorly understood as a result of misidentification of the two similar thrips species and near absence of previous study. To determine the distribution and abundance of the two thrips species on B. alba and if it is a host of the congener species, flowers of B. alba were sampled at 10 mile increments from the southern extreme of the Florida Keys to near the northern border of Georgia. Adults and larvae were identified to species and a morphological instar II larval key was developed. Other plant species were sampled at three distant locations to determine the abundance and distribution of F bispinosa and F. cephalica on B. alba compared to different plant species. Non-destructive DNA template extraction, polymerase chain reaction and sequencing of the cytochrome oxidase c subunit one mitochondrial gene of specimens from the three sample locations were conducted. Three distinct latitudinal regions in Florida were found to have either a single congener species or both congeners on B. alba flowers. Both species utilized B. alba for Advisors/Committee Members: FUNDERBURK,JOSEPH E (committee chair), STOUTHAMER,RICHARD (committee member), ADKINS,SCOTT T (committee member).
