This can be caused directly, through girdling of the root cambium, or indirectly as the weakened host becomes susceptible to disease. [1], Pupation occurs near the soil surface in a cell constructed of soil and root material. A mature larva of these species is often three inches or more in length. [2] A synthetic mixture of all four possible isomers of 3,5-dimethyldodecanoic acid is highly attractive to male P. californicus in field trials.
