Timing is everything when it comes to effective pest management. Knowing when a pest is susceptible to which kind of pesticide is the key for successful control. Coupled with OBLR phenology, Dr. Jones identified four windows in time when OBLR control is effective: 1) 90 degree-days (DD) – larvicide application, when overwintering larvae are becoming active in spring, 2) 720 DD – ovicide application (e.g. oil), when eggs of the first summer generation are being deposited, 3) 900 DD – larvicide + oil application, when eggs and young OBLR larvae are abundant, and 4) 1800 DD – larvicide + oil application, when eggs and young OBLR larvae of the second summer generation are abundant.
