PARASITES AND OTHER ORGANISMS ASSOCIATED WITH NESTS OF AMEGILLA FRIESE (HYMENOPTERA: ANTHOPHORINAE)

i Amegilla (Amegilla) pulchra (Smith) (Anthophorinae, Anthophorini) is parasitised by Thyreus caeruleopunctatus (Blanchard) (Anthophorinae, Melectini), Miltogramma sp. (Sarcophagidae), Zonitis sp. (Meloidae), and fungus, and information is given on the habits of the parasites and the number of cells parasitised. A specimen of Thyreus nitidulus (Fabricius) was seen working in a nest. Trogoderma apicenne Reitter (Dermestidae) and Lasioderma serricorne (Fabricius) (Anobiidae) were reared on debris in old cells. Amegilla (Asarapoda) sp. is parasitised by Thyreus lugubris (Smith). Pyemotes ventricosus (Newport) (Acarina, Pyemotidae) killed pupae of both species of Amegillain open cells. A. (A.) pulchra is the first hymenopterous host recorded for an Australian Meloid
