This Þeld survey, the second noting the occurrence and diversity of Þlth ßy pupal parasitoid fauna in Hungary, was performed on beef and dairy feedlots and swine facilities in the southern and eastern parts of the country. The Þlth ßies Musca domestica L. and Stomoxys calcitrans (L.) were the two most commonly parasitized hosts. The three species of Spalangia recovered, in decreasing order of a...

Three flavonoidal aglycones viz; F1 (Chrysin), F2 (Kampferol) and novel F3( 3,7dimethylether quercetin), were isolated from acetone wash of fresh leaves of Datura stramomium L. Isolated compounds were identified on the basis of their physico-chemical properties, Co-TLC, H-NMR, C-NMR and CIMS specrtum. Significant cytotoxic activity against three tumor cell lines (liver, cervix & breast), was re...

Adult specimens of Cochliomyia macellaria, Chrysomya megacephala, Ch. rufifacies, Lucilia sp. (Calliphoridae), Musca domestica (Muscidae), Oxelytrum discicolle (Silphidae) and Sarcophagidae were recovered from 12 human cadavers in Cali, Valle, Colombia. Information regarding these findings is presented.

Adult and immature individuals of many insect species can survive anaerobic conditions for periods ranging from 4 hr. to 4 days, and even in a few cases for longer periods up to 56 days (see Brand, 1946, for numerous references). The present paper describes an investigation into some effects of anoxia on adult Musca domestica. A preliminary account of part of this work has been published (Heslo...

House flies are of major concern as vectors of food-borne pathogens to food crops. House flies are common pests on cattle feedlots and dairies, where they develop in and feed on animal waste. By contacting animal waste, house flies can acquire human pathogenic bacteria such as Escherichia coli and Salmonella spp., in addition to other bacteria, viruses, or parasites that may infect humans and a...

TOTAL of nine house fly mutants which occurred spontaneously or were A induced by X-ray were listed by two Russian investigators, SARKISSIAN (1941) and SEREBROVSKY (1941). These may have been the first attempts at the formal study of the genetics of Musca donestica L. Apparently these-investigators did not continue and extend this work subsequently. Recently, in connection with problems of resi...

1. The ATPase activity of insect mitochondria has been investigated. A comparison was made to determine the distribution and nature of such activity in other isolated fractions of the house fly, Musca domestica L. 2. The ATPase in insect mitochondria is specific in that orthophosphate can be cleaved only from ATP. The Michaelis-Menten constant K(8) = 2.78 x 10(-3)M and V(max.) = 76 micrograms P...
