Research Project: Assessing Persistence and Efficacy of New Insecticides in Pistachios

Location: Commodity Protection and Quality Research

Project Number: 2034-43000-040-06-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Mar 1, 2013
End Date: Dec 31, 2016

Investigate spray timing and the adult activity of the new soft insecticides in pistachios that target navel orangeworm (Amyelois transitella).

Pistachios will be sprayed by commercial cooperators using a suggested timing and collected at intervals over a 4-8 week period. These pistachios will be challenged in the lab by infesting them with known numbers of eggs and assessing adult emergence. Additional experiments conducted in the field will assess insecticide efficacy against sentinel eggs and adults. Field infestation estimates will be compared to damage levels determined by the processor. Adult activity will be determined by a combination of studies conducted at industry research farms and by caging adults in the field.
