Three hundred forty female jewel wasps were reared as larvae on blowfly pupae and then separately exposed as adults to varying numbers and combinations of previously parasitized and unparasitized housefly pupae. Each adult was tested with 6 fresh housefly pupae. Only foraging experience on unparasitized housefly pupae increased host acceptance for subsequent housefly pupae, producing curvilinea...

The oxidation of 3,5-di-tert.-butylphenyl N-methylcarbamate (Butacarb) has been studied in the flies Musca domestica and Lucilia sericata, grass grubs Costelytra zealandica and the mouse. In all species eleven oxidation products, which were formed by hydroxylation of the tert.-butyl groups and the N-methyl group, were detected.

Twenty-seven species of calyptrate muscoids (Muscidae and Sarcophagidae) were collected from December 1993 to November 1994 with wind oriented traps (W.O.T.) baited with decomposing beef liver at the Rio de Janeiro Zoo. The most abundant species found were Musca domestica (57.84%), Peckia chrysostoma (28.16%), Ophyra aenescens (17.11%), Oxysarcodexia thornax (17.82%), Synthesiomyia nudiseta (13...

We present a probe-based, phase-referenced low coherence interferometer in which the reference field is provided by a fiber end reflection. A gradient-index microlens focuses light onto a sample and collects reflected light. We use the probe interferometer to measure surface profiles of the compound eye of a housefly (Musca domestica) and measure nanometer-scale vibrations in a test sample.

Comparison of prestomal teeth of adult Chrysomya megacephala, Chrysomya rufifacies, Chrysomya nigripes, Lucilia cuprina, Parasarcophaga dux and Musca domestica was accomplished by use of scanning electron microscopy. The prestomal teeth of C. megacephala, C. rufifacies, L. cuprina and P. dux are all similar in appearance in having various degrees of bifurcation at their tips. In contrast, the t...

Spatial genetic variation was assessed in the common house fly Musca domestica. Allozymes at three gene enzyme system unraveled ten loci which revealed seventeen alleles in house fly populations. F statistics revealed that except ACPH-1 and EST-3 all the other loci show inbreeding (Fis>Fst). Persistent heterozygosity was observed in ACPH-1(Fis= -0.140) which indicate random mating for this locus.

Reproduction and longevity of Supputius cincticeps (Stål) (Heteroptera: Pentatomidae) fed on Zophobas confusa Gebien, Tenebrio molitor L. (Coleoptera: Tenebrionidae) or Musca domestica (L.) (Diptera: Muscidae) larvae were studied during two generations at 24.7 ± 1.1oC, 70 ± 10% R.H. and 12 h of photophase. Body weight of newlyemerged adults, oviposition period, number of egg masses, total numbe...

An insect grwoth regulator (IGR), Thompson-Hayward TH 6040 (N-(4-chlorophenyl)-N'-(2,6-difluorobenzoyl)urea), incorporated in the feed of rhinoceroses at rates of 1 and 0.1 mg/kg inhibited development of Musca domestica L. and Stomoxys calcitrans (L.) in the feces.

Most rhabdomeres in the eye of the fly (Musca domestica) are fluorescent. One kind of fluorescent emission emanates from a photoproduct of the visual pigment, other kinds may be ascribed to photostable pigments. These phenomena provide not only a means of spectrally mapping the retina but also a new spectroscopic tool for analyzing the primary visual processes in vivo.
