Abstract
Potter wasps belong to the subfamily Eumeninae of the family Vespidae. Potter wasp is a common name given for a group of caterpillar hunting wasp which builds the pot-shaped mud nests. Initially the wasp constructs the nest and then starts hunting for its prey, the caterpillars. The prey is stung and paralyzed by the wasp then brought to the nest. It is perhaps a very highly specific behavior of these wasps. The female wasp lays her egg on the prey. The egg is firmly attached to the prey and the larva hatching out sucks the haemocoel which oozes out from the prey. In the present study, the biochemical changes in the haemolypmh of Helicoverpa armigera (Lepidoptera: Noctuidae), before and after stinging by the potter wasp were observed. There is considerable change in the nutritional physiology of parasitized prey. The successful development of the parasitoid depends on the concentration of the host haemolymph. Hosts do not survive and thus parasitoids play an important role in regulating the population of the hosts

Insect parasitoids are highly efficient at manipulating the physiology, metabolism, and endocrinological state of their hosts
Summary
The Order Hymenoptera (Latin for “membrane wing”) is a vast assemblage of insects. Hymenoptera has around 115,000 species and is well represented by the ants, bees and wasps. Hymenopterans inhabit a wide variety of habitats, and show an incredible diversity in size, behavior, structure and color. They have a typical way of living on the ground utilizing the environments fully and at the same time controlling other insects [1]. The wasps studied for our observation were Eumenes conica which are known as potter wasps. Potter wasps belong to the subfamily Eumeninae of the family Vespidae. It is a widely distributed subfamily which includes about 3,000 species in more than 150 genera [3]. The best-known Eumeninae are the potter wasps (Eumenes). All the known eumenine species are predators; most of them solitary mass provisioners, though some isolated species show primitive states of social behaviour and progressive provisioning
