With the recent extraordinarily cold nighttime temperatures though, degree-days are not accumulating very fast. What this will translate to in terms of worm populations is not known, because there are many factors that cause larval mortality including cold temperatures, rain and fog, diseases and predators. Microbial pesticides are most effective when applied approximately 400-550 degrees after moths begin flying, when the population consists primarily of 1 st and 2 nd instar larvae. See your Citrus IPM manual or guidelines for details of how to sample.
