Mature adult female is a robust glossy black beetle, notice that it is larger than most ambrosia beetles. It measures 3.7 millimeters in length |
| 1274030 |
camphor shot borer |
Xylosandrus mutilatus |
Just under the scutellum in a female, you will find the mycangia. The mycangia Is a highly specialized saclike organ of ectodermal origin, which is used by the beetle to maintain and transport fungi during dispersal. Notice the honeycomb appearance of the mycangia. |
| 1274031 |
camphor shot borer |
Xylosandrus mutilatus |
A close look into the ultrastructure of the mycangia yields many fungal spores and segmented hyphae. From (Kajimura and Hijii 1994) and (Kinuura 1995), the primary food source for the larvae and adults is a species-specific fungus in the genus Ambrosiella. |
| 1274032 |
camphor shot borer |
Xylosandrus mutilatus |
The mature adult male is dwarfed and flightless. The sex ratios in ambrosia beetles can be (10:1) to (30:1) female to male. The males are rarely seen. After mating with the mother beetle or late emerging sisters, the male dies. |
| 1274033 |
camphor shot borer |
Xylosandrus mutilatus |
The eggs are ellipsoidal in shape and are white, shiny, and soft. Notice the thickness of the fungi lining the gallery wall. |
