      The interactions and inter-relationships between plant galls and the chalcids with them are often extremely intricate and it is not easy always to assess correctly a given species as a gall former or an inquiline or a parasite of another inhabitant of a gall. The chalcids show complex inter-relationships with other inhabitants of a gall in many instances. The existence of both phytophagy and entomophagy in the same species or in the same individual is an interesting phenomenon met with in some species of chalcids associated with plant galls. The host-finding and host-acceptance behaviour of some of the gall-chalcids are other interesting aspects discussed.

    • An analysis of the superparasitic behaviour and host discrimination of chaicid wasps (Hymenoptera: Chalcidoidea)

      Superparasitism is frequently met with in chalcids. The actual mechanism of suppression of the supernumerary individuals is by mutual combat though exceptions to this general rule may also be seen rarely. Many chalcids are known to discriminate between parasitised and healthy hosts. It is an interesting phenomenon that superparasitism occurs even when a female is capable of discriminating parasitised and unparasitised hosts. Several factors play prominent roles in causing superparasitism and the avoidance of superparasitism by a chaicid is the result of maximisation of its reproductive success.

      More Details Abstract Fulltext PDF

      The Chalcididae represent a large group of parasitic Hymenoptera which parasitise pupal or larval stages of various insects including several pests. Their phylogeny is not so far clearly known, but a Eurytomid—Torymid line of accent could be postulated. There is a general resemblance in their adult behaviour such as emergence, courtship, mating, oviposition, feeding etc. Their hosts belong to Lepidoptera, Diptera, Hymenoptera, Neuroptera, Coleoptera and Strepsiptera.
