Expressing bnl^HMS01046 under the control of Scer\GAL4^Hml.Δ, Scer\GAL4^lz-gal4 leads to wasp-infested larvae to develop fewer melanotic spots than controls. In the setting of Scer\GAL4^Hml.Δ-driven expression, the larvae that can melanize wasp eggs display a reduction in melanotic mass size and a reduction in the number of Hml+ cells around the wasp eggs; unlike in controls, there are a few crystal cells around the wasp eggs. In the setting of Scer\GAL4^Hml.Δ-driven expression there are also decreases in the numbers of total hemocytes, Hml+ plasmatocytes and lamellocytes after wasp-infestation, but not under control conditions.

Expressing bnl^HMS01046 under the control of Scer\GAL4^bnl.PU occasionally leads to stunted air sac primordium development, compared to controls.

Expressing bnl^HMS01046 under the control of Scer\GAL4^NP2211 leads to absence of, or stunted, air sac primordium in the wing disc.
