The ambrosia beetle, Euwallacea fornicatus Eichhoff, was first recorded in Israel in 2009. The symbiotic fungus Fusarium sp., carried in mycacangia located in the anterior region of the female head, is responsible for the typical wilt symptoms inflicted on avocado (Persea americana Miller) trees. The beetle–fungus complex has become a serious threat to the future of the avocado industry in Israel.
