Symptoms of O. rhabdota View in CoL damage in M. conifera and M. mediocris trees
Orientozeuzera rhabdota was associated with tree damage and stem or branch breakage. Infested M. conifera and Mi. mediocris trees have circular holes with a diameter of 0.2–0.6 cm in the boles ( Fig. 2a, d View Figure 2 ) or branches ( Fig. 2b View Figure 2 ), located 15–380 cm above the ground. There are many droppings around the base of the damaged trees ( Fig. 2a View Figure 2 ). Droppings are discrete, semi-circular faeces, white at first, then brown, and gray. The tunnels go directly into the boles and then straight down the middle of the stems, then back up again. The tunnels are 60–80 cm long and 0.7–1.1 cm in diameter. There are webs of mixed wood mulch blocking the openings of the entrance holes ( Fig. 2f View Figure 2 ).
Last instar larvae and prepupae make exit holes just above the entrance holes ( Fig. 2h, i View Figure 2 ) but retain the thin bark of the tree for protection. Before maturing, the pupae push at the thin bark at the exit holes and squeeze out one third of the pupa’s head ( Fig. 2i View Figure 2 ). Severely damaged trees can have 6– 12 larvae in the bole and branches, and the damaged trees ( Fig. 2b View Figure 2 ) or branches are easily broken during strong winds.
