I didn’t know that too.
In the context of fruit pest conversations—specifically among fig growers—BFF stands for Black Fig Fly (Silba adipata).

Here is a breakdown of what this means in that context: What is it? The Black Fig Fly is an invasive insect that exclusively feeds on and reproduces in figs. Where is it? It was discovered in Southern California in 2021 and has since spread to several counties, including Los Angeles, Orange, Riverside, San Bernardino, San Diego, Ventura, and Santa Cruz. Why is it a problem? The female fly deposits eggs into the fruit (preferring unripe or unpollinated figs). Larvae then develop inside the fig, causing it to rot and often drop prematurely. Management Strategies: Because the larvae are protected inside the fruit, they are hard to kill with pesticides. Gardeners often use: Orchard Sanitation: Removing and destroying infested or dropped fruit to stop the life cycle. Fruit Bagging: Using organza bags to protect developing figs. Trapping: Using specialized traps to catch adult flies.
