A study was made on the predatory responses of spiders to te house fly, Musca domestica vicina, which is an important household pest. In this experiment, 123 spider species belonging to 28 families were used in total. The prey flies were captured by 91 species belonging to 20 families. Among them, 41 species (14 families, 26 genera) were recognized as the useful natural enemies because of their efficiency in capturing flies and abundance in nature. The main families capturing the flies were found to be the following three; Argiopidae, Salticidae and Agelenidae. A series of experiments was conducted to observe the feeding behaviour of the following four species; Heteropoda venatoria, Tegenaria domestica, Plexippus paykulli and Theridion tepidariorum. P. paykulli captured all 20 flies put in a cage for a seven day period. However, H. venatoria captured 15 flies out of 20 for only three day period and showed no feeding behavior after. The mean number of daily capture was 4 or 5 flies for both T. tepidariorum and P. paykulli regardless of the prey density. Whereas, the others showed the increased number of capture according to the increase of prey density. H. venatoria prefered to catch cockroaches rather than flies but P. paykulli captured only flies.
