Crisicoccus pini (Kuwana, 1902) - (Kuwana pine mealybug)
This mealybug is found in eastern Asia (Japan, Korea, parts of China, Taiwan) and has been introduced into other regions like North America (recorded in several parts since the 1960s) and Europe (first record in 2006). It mainly infests pine species like Pinus densiflora and Pinus thunbergii, but can also develop on several other conifers of Abies, Keteleeria and Larix species.
Heavy infestations result in yellowing, premature dropping of needles, dieback and even tree death. There are typically 2 generations per year, with nymphs of the 2nd generation overwintering in cracks of the bark.
Mature females are light reddish brown and have an oval shape with a size of about 4 x 2 mm. The wax filaments on the last abdominal segment are short, compared to many other mealybug species. Females are surrounded by cottony wax secretions.
For a review see the EFSA Panel on Plant Health report (2021).
