Third instar larvae expressing TobEY12182 under the control of Scer\GAL4Pxn.PS have a decreased number of sessile hemocytes. The number of hemocytes in circulation is similar to wild type. The dorsal sessile hemocyte department is disrupted. Sessile hemocytes accumulate along the dorsal vessel but do not spread through the cuticle. The lymph gland is not enlarged. Hemocyte shape is normal.
