Rose Blister Gall Wasp(Dioplolepsis rosaefolii)Latin Name: Rose Blister Gall Wasp
Common Name: Dioplolepsis rosaefolii
Appearance:
Diplolepis rosaefolii the gall consists of tissue layers, enclosing a centrally located larval chamber.
The larval stages of the cynipid wasp Diplolepis rosaefolii cause single‐chambered, lenticular galls on the leaves of the wild shrub rose, Rosa Virginiana.
The formation of Dioplolepsis rosaefolii galls is substantially different from that of other Diplolepis galls researched since it involves several traits that are unique to this gall. Hosts plants: creates round galls on cottonwood, poplar and aspen petioles; damage primarily aesthetic
Territory:
Throughout North America
Damages caused by Rose Blister Gall Wasp:
The genesis of D. rosaefolii galls is notably different from that of other Diplolepis galls examined.
Description about Leafminers:
Leafminer adults are tiny flies with yellow sections on their thorax, legs, and abdomen. They are 0.1 inches (2.5 mm) long, black to blue, and have yellow portions on their thorax, legs, and abdomen. There is generally a visible yellow patch at the base of the wings. The tiny white eggs are hidden behind the leaf’s epidermis and develop in 4 to 6 days. Pupation takes happen underground or in mines. During the summer, the life cycle takes around 23 days. Every year, three to five generations pass. Leafminers infrequently afflict beans. The majority of the time, their quality deteriorates after the harvesting season. Large whitish blotches or, in the case of serpentine leafminers, thin, white, winding paths into the leaf’s core occur from the larvae eating between the upper and lower leaf surfaces.
Life History and Habits:
Rosaefolii Dioplolepsis In the spring, females lay their eggs in plant buds, and galls are completely formed late summer. The larvae feed on the leaf bud tissue inside the galls, and the pupae stay there until the following spring.
