Types of parasitism

3. Parasitism:-
This is a kind of symbiosis in which parasitoid
live at the expense of the host and killing the
host in the process of development. Parasitism
is an act of attack and ovipositioning the egg
with the help of ovipositor by the parasitoid on
the host.

4. Types of parasitism:-
Simple parasitism:-
A single attack of parasitoid
on the host irrespective of the number of egg laid.
E.g. Goniozus nephantidis on larvae of coconut
black headed caterpillar (BHC)
Super parasitism :-
Many individual of same
species of parasitoid attack a single host at a time.
E.g. Trichospillus pupivora on pupae of BHC

5. Multiparasitism :-
Parasitism by different
species of parasitoid on the same host at a time.
E.g. Bracon brevicornis (braconidae) , Eriborus
trochanteratus (ichneumonidae) and Gonizus
nephantidis (bethylidae) on larvae of BHC
Hyper parasitism:-
A parasitoid attack on another parasitoid .
E.g. Pleurotropis sp. Hyperparasitoid on Bracon
brevicornis a primary parasitoid
Asaphes sp. On Aphidilus sp. (parasitoid of aphids)

6. Auto parasitism
(Adelphoparasitism):-
Female develop as a
primary parasitoid, but the male is a secondary
parasitoid through females of its own species. This is
also called as heteronomous hyper parasitoid.
E.g. Encarsia formosa attacking scale insects and
whiteflies
Cleptoparasitism:-
A parasitoid attacking a host,
already parasitized by another species of parasitoid.
E.g. Pine shoot moth attacked by either Eurytoma
pini or Rhyacionia buoliana one followed by
another.

7. Endoparasitism:-
parasitoid developing
within the host body intenally.
E.g. Aphelinus mali on wooly aphid , where only a
single larvae completes its development is called
solitary endoparasitism
E.g. Itoplectis on pine sawfly and many larvae
develop to maturity in single host is called
Gregarious endoparasite
E.g. Apanteles congregatus.
Ectoparasite:-
Parasitoid developing
externally on host body.
E.g. Epiricania melanoleuca on sugarcane pyrilla.
