Prospecting wasp, ant and bee venom for active bio-molecules has gained considerable interest among researchers in recent years. Collecting sufficient quantity of venom from solitary wasps without sacrificing them is often difficult. Here we describe a non-invasive technique for collecting venom from a solitary wasp Delta conoideum Gmelin (Red-backed potter wasp). Venom was milked by presenting an agar block to a single female wasp for stinging. The venom was extracted from the agar block using ACN: water solvent system. The total protein in venom was estimated quantitatively and the presence of peptides in the venom was confirmed by MALDI-TOF analysis. The proposed technique is non-invasive and pure venom can be repeatedly 'milked' using this method from other wasps and also bees without the need for sacrificing a large number of individuals.
