This is not good, looks like Fusarium. A new beetle that vectors a Fusarium dieback on avocado trees has been discovered in and near Los Angelesin 2013. Symptoms of Fusarium dieback disease Look for a single entry/exit hole with surrounding white powdery exudate that is either dry, or surrounded by wet discoloration of the outer avocado tree bark. During the early stages of colonization, there may not be any visible injury to the bark. Scrape off bark around an infected area or entry/exit hole to look for brown discolored necrosis caused by the fungus. The entry hole on an avocado tree is about 0.033 inches wide. The beetle larvae live in galleries within the tree and feed on the fungus. Examine the area around the gallery for the discolored necrosis caused by the fungus.

Many fruit trees (and maybe other plants, too) are alternate bearers - they alternate between a big crop one year and a smaller one the next, then repeat the cycle. Japanese persimmons and olives are two that I have experience with. Sometimes you get two bang-up years in a row; I had about 250-300 fruit on my Fuyu persimmon last year and this year looks about the same. Avocado may follow the same pattern. They look yummy!
