UAS regulatory sequences drive expression of a short inverted repeat.
Expressing btlHMS02656 under the control of Scer\GAL4Hml.Δ or Scer\GAL4srp.D.cCa leads to wasp-infested larvae to develop fewer melanotic spots than controls.
The expression under the control of Scer\GAL4srp.D.cCa, under control conditions, leads to a decrease in the number of Pxn+ cells. Upon wasp infestation, larvae show an increase in total number of hemocytes, and an increase in the number of Hml+ crystal cells. and a decrease in the number of lamellocytes.
