1. The behaviours of monocular and binocular flies are compared with respect to the landing reaction. It is found that landing reaction is elicited through different mechanisms by stimulating the zones of single or of double vision: M onocular stim ulation in the field of single vision evokes reactions with both ipsilateral and contralateral legs; monocular stimulation in the field of double vi...

Houseflies (Musca domestica L.) are a major pest species of livestock units and landfill sites. Insecticide resistance has resulted in an increased emphasis on lure-and-kill control methods, but the success of this approach relies on the effective attraction of houseflies with olfactory or visual stimuli. This study examined the efficacy of olfactory (cuticular hydrocarbons) or visual (colours ...

According to Sacca (1956) the three forms of Musca domestics, M. d. domestica, M. d. nebulo and 1k!. d. vicina constitute a cline. Of these only the last two are found in India. They are characterized by having four well defined dark stripes on the thorax but while all stripes are complete in vicina, the two submedian ones are incomplete in nebulo (Figure 1). This offered an opportunity to stud...

Five field populations of Musca domestica L. collected in poultry farms were bioassayed in order to detect possible resistance to the larvicide cyromazine in Brazil. The concentrations used were 0, 0.5, 0.1, 0.2, 0.4, 1, 2, 4 and 8 ppm. Three populations (Petrópolis, RJ, Montes Claros, MG and Promissão, SP) were resistant, while the other two populations (Ibiuna, SP and Monte Mor, SP) were more...

Nature has evolved an astonishing variety of genetic and epigenetic sex-determining systems which all achieve the same result, the generation of two sexes. Genetic and molecular analyses, mainly performed during the last 20 years, have gradually revealed the mechanisms that govern sexual differentiation in a few model organisms. In this review, we will introduce the sex-determining system of Dr...

—Linnaeus described 37 species of flower flies (Diptera: Syrphidae). His collection was studied, and the current status of all his flower fly names is given. Six new synonyms are established (Scaeva annulipes Zetterstedt = Eriozona erratica (Linnaeus), Musca citrofasciata DeGeer = Xanthogramma /estiva (Linnaeus), Xylota curvipes Loew = Chalcosyrphus femoratus (Linnaeus), Chrysogaster chalybeata...
