5.6.2 ORQNISHS ASSOCIATED WITH MIE NESTS <strong>OF</strong> FU14GUS-GMWING TMMTLS - Many different types of organisms arefound associated with termites, p4including the ýhcrotermltinae)j living within their nests and in some cases specifically associated with the fungtts comb&'- The physical protection and relatively controlled environmental conditions found in tho mounds attract many animalst mostly Insects, to spend part or all of their lives In association with termites* and these are known an termitophiles (14a and Wood 197JL)- nePtilest mar=aln and birds also live in termite'tunuids or use them an nest siteng and species of parasites (ftmg1t protozoal nematodest mites and insects) and predators (especially ants) are also found there., At Wwa the foodstores of the Hacrotemes bellicosus mounds investioated were found In particular to contain nematodes and larvae of the dipteran Tricyclea deepln2i Zx=pt. Mites were present on the fungus combso The degree of-association between fungi and the Macrotermitinae in variable and an attempt Ix made here to classify those relationships$- (1) Mutuallstic and obligate symblontse TermltomXcex species grow on the fungus combs In InhAbited nests* They may also be carried as conidia In the gut of workersand alates In some termite species (692)9 Fruit bodies develop either by punhing through the soil or nest, from the fungus comb to the surface (a, go Ancintrotem, ell app)l or by 4developing from fungus comb scattered on the surface by the termites (e9go Odontotermes BPPe)- (2) Parasites. - Metarhizium ftd! onliae Varo anisonliag Uas found on Macratermas- subhyallnus alates. Parasiten 251, are found associated with
all species of termitest and Smay be azoociated with other Insectso They may be endoparanites or ectoparasites 1952al and Coroomycetop2is ofadiMs (e. go Termitari_aq Dakshi 1962t 1181in 1952a) (e. go Antennol! nio on Reticulitermes flavip",, Heim Obligate saprophytess (Blackwell and Kimbrough 1976)s (a) on the fungus combs of the Macroteraitinae.
