“…Malameba locustae is a protazoan parasite of Acrididae. Taylor & King (1937) attempted to infest many species of grasshoppers with this parasite. H. alba was one of only two species that did not become infested.…”

Hypochlora alba (Dodge) is a specialist grasshopper that lives and feeds almost exclusively on the sage brush Artemisia ludoviciana Nutt., a plant mostly avoided by the generalist grasshopper Melanoplus sanguinipes (Fabr.). Analysis of leaves, seed heads, and glandular trichomes by gas chromatography-mass spectrometry revealed 1,8-cineole, camphor and borneol to be the major monoterpenes and achillin the major sesquiterpene lactone. These terpenoids increased over the growing season and were two to five times more concentrated in the seed heads than in the leaves. Gustatory choice tests showed a feeding stimulant(s) for H. alba to be present in extracts of A. ludoviciana and A. carruthii Wood, a closely related species that H. alba will feed upon, but not in a non-host species, A. filifolia Torr. This stimulant activity was found in a fraction containing primarily monoterpene hydrocarbons. Other fractions containing sesquiterpene lactones had antifeedant activity against M. sanguinipes. Tests with achillin showed the average foliar levels (ca. 2~ dry weight) to be above the rejection threshold of the generalist (0.5~ but below that of the specialist (4~ Reproductive tissue contained average levels greater (ca. 7~ than the rejection threshold of either species.

“…The protozoan parasite, Malameba locustae, is endemic in grasshoppers in both South Africa (Lea, 1958;Prinsloo, 1960) and North America (Taylor & King, 1937) and occurs frequently in laboratory colonies of grasshoppers (Henry, 1968).…”

“…The trophozoites in the present form reach a maximum size of 13.5 x 7.0/zm while in Malamoeba locustae originally reported by King and Taylor (1936) and taylor and King (1937) measured 5-10/zm in diameter. Steinhaus and Marsh (1962) who reported the parasite from 3 species of Melanoplus observed that the trophozoites were generally spherical ranging from 4-12 am in diameter in fresh preparations.…”

“…Prell (1926) Melanoplus. Taylor and King (1937) carried out further studies on M. locustae King and Taylor, 1936 and compared with M. mellifica Prell, 1926 and found that P.03)--5 they did not belong to the same genus, because the endosome in Malpighamoeba mellifica divided without fragmenting forming polar caps as in the case of VaMkampfia whereas in the case of Malpighamoeba locustae the endosome disintegrated and chromosomes and fibrils are formed as in Hartmannella. Hence they proposed erection of a new genus Mdlamoeba and designated M. locustae described by them earlier (King and Taylor 1936) as the type species.…”

A new species of histozic amoeba, Malaraoeba indica parasitic in the epithelial cells of the midgut and the lumen of the Malpighian tubules of Poecilocera picta is described. The trophozoites reach a maximum size of 13.5 × 7.0m and divide by binary fission after the endosome breaks down into chromatin masses. The cysts are ellipsoid with an outer thin refractile wall and measure 14.5 x 8.6 ~um in the fresh condition and 13'5 × 7-5/tm in the fixed and stained condition.
