Development of a sequential sampling plan for classifying Thrips tabaci (Thysanoptera: Thripidae) populations in onion fields.

Onion thrips, Thrips tabaci Lindeman, is a global pest of onion crops, causing substantial economic damage by diminishing bulb yields and transmitting plant pathogens. Insecticides are used to manage T. tabaci infestations with control decisions traditionally based on action thresholds that require visually counting thrips on a fixed, predetermined number of onion plants per field.

Identifying Onion Fields at Risk of in New York.

(IYSV) poses a significant threat to dry bulb onion, L., production and can lead to substantial yield reductions. IYSV is transmitted by onion thrips, (Lindeman), but not via seed.

Spatiotemporal Patterns of Iris Yellow Spot Virus and Its Onion Thrips Vector, , in Transplanted and Seeded Onion Fields in New York.

Onion thrips, (Lindeman), transmits iris yellow spot virus (IYSV) and is one of the most important pests of Allium crops. IYSV is a member of the species in the genus of the family . This virus typically reduces overall onion bulb quality and weight but can also prematurely kill onion plants.

A Survey of Declining Palms (Arecaceae) With 16SrIV-D Phytoplasma to Evaluate the Distribution and Host Range in Florida.

The 16SrIV-D phytoplasma was first identified in Florida in 2006. Since its discovery, it has spread throughout most of the state. It is most prevalent in the central part of Florida, from Hillsborough County on the west coast to St.

Detection and Quantification of the 16SrIV-D Phytoplasma in Leaf Tissue of Common Ornamental Palm Species in Florida using qPCR and dPCR.

Lethal bronzing disease (LBD) is a lethal decline of various palm species caused by the 16SrIV-D phytoplasma. The disease was described in Texas in 2002 but found in Florida in 2006. Since its introduction, the phytoplasma has spread throughout much of the state.

Bee Community of Commercial Potato Fields in Michigan and Bombus impatiens Visitation to Neonicotinoid-Treated Potato Plants.

We conducted a bee survey in neonicotinoid-treated commercial potato fields using bowl and vane traps in the 2016 growing season. Traps were placed outside the fields, at the field edges, and 10 and 30 m into the fields. We collected 756 bees representing 58 species, with spp.
