Spiny Rose Gall Wasp – Dioplolepsis bicolor

Spiny rose Gall Wasp (Dioplolepsis bicolor)

Latin Name: Dioplolepsis bicolor

Common Name: Spiny rose Gall Wasp

Appearance:

• Spiny rose gall wasp is a tiny wasp that encourages galls to shape the leaves.
• The spiny rose gall has a hard circular body with several spiky protrusions.

Host plants:

Territory: Throughout North America

Damage caused by spiny rose gall wasp:

A tiny wasp is known as the spiny rose gall wasp causes galls to grow on the leaves. Galls can develop on the leaves, stems, buds, or roots. The wasp’s larva is within the gall. The rugged body of the spiny rose gall is spherical, with numerous spiky protrusions. Buds expand and harden as a result of other gall wasps.

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:

The insect spends the winter as a larva in the gall, and the adult wasp grows and chews its way out in the early spring. It searches for growing leaf tissue on which to lay its eggs. The eggs hatch and the larvae feed on them, causing the gall to develop around them. Every year, a new generation is born.
