Research Project: NAVEL ORANGEWORM IN PISTACHIOS--ABUNDANCE, DISPERSAL, AND DISRUPTION OF SEXUAL COMMUNICATION Project Number: 5302-43000-034-04
Project Type: Trust

Start Date: Oct 01, 2007
End Date: Dec 31, 2011

Objective:
1) Compare abundance in and movement between adjacent plantings of almonds and pistachios; 2) compare almond meal and phenyl propionate as female attractants; and 3) characterize minimal grouping of timed aerosol dispensers (puffers) necessary for complete elimination of males captured in traps baited with virgin female navel orangeworm.

Approach:
1) Mark-capture with protein markers and mark-release-recapture with fat-soluble dye will be used in conjunction with grids of traps baited with virgin females (for males) and almond meal (for females) to characterize movement and obtain estimates of adult abundance. 2) Sticky traps and bucket traps containing almond meal and phenyl propionate will be placed in replicated blocks in almonds and pistachios, with each block also including a virgin-baited flight trap for comparison. 3) Two north-south columns of three puffers each will be placed in replicated blocks in pistachios at inter-puffer distances of 209 or 148 feet, and three sticky traps baited with virgin females will be placed in a north-south line equidistant between the two lines of puffers, with the center traps directly between the two middle puffers and the other two traps directly north and south at a distance half that of the inter-puffer distance. Traps will be tended over 9 to 15 weeks between May and August. Documents Trust with Resnick Foundation. Log 34060. Formerly 5302-43000-031-14T (6/2008)
