J. Econ.Entomol.78: 722-724 (1985) ABSTRACT A residue on glassexposure technique was compared with topical application as a method of assessingpermethrin resistance in a house fly (Musca domestica L.) population. Multiple levels of treatment permitted development of significant dosage-mortality lines with both techniques. Average resistance factors were ca. 150 with the topical application tech...

Soil samples (n=500) collected from different areas of Pakistan were screened for various species of Bacillus by Gram staining, spore staining and by a number of biochemical tests. Seven identified species i.e. B. thuringiensis, B. sphaericus, B. brevis, B. firmus, B. coagulans, B. stearothermophilus and B. megaterium were then administered to the house flies, Musca domestica to ascertain and e...

The phototactic choice of some pairs of colored lights by Musca domestica and Lucilia sp. after a rise in intensity of the non-preferred light in spontaneous responses was studied. In the range of spectrum where no preference in spontaneous responses is noted, the brighter light was chosen after its intensity was increased. It is difficult or even impossible to change the preferences of insects...

A current debate within the cognitive development literature addresses how best to characterize conceptual change. Within one proposal, development primarily consists of a series of radical conceptual shifts or restructurings in which the most current understanding is inexplicable within (incommensurate with) prior conceptual structure. Alternatively, development is discussed as more gradual en...

A chitin synthesis inhibitor, novaluron, was evaluated under laboratory conditions for its larvicidal activity against a field population of the housefly, Musca domestica L. (Diptera: Muscidae), by feeding and dipping methods. The concentrations used were 1, 2.5, 5, 10 and 20 mg a.i./kg in both methods. The product caused >80% larval mortality at 10 and 20 mg a.i./kg. Of the two methods, feedin...

Neonicotinoids are currently the fastest-growing class of insecticides. In 2004, imidacloprid (a neonicotinoid) was registered for house fly control in the United States. This study was undertaken to examine the relative susceptibility of laboratory strains of house flies to imidacloprid using a feeding assay, to determine the relative susceptibility of field collected house flies before imidac...

House flies, Musca domestica L., developed in 200 cm3 of coarse sand containing just 1 ml (0.47%) of dairy manure solids and 10 ml (4.74%) of moisture. At these levels, development was slow (21.5 d from 1st instar to adult), adult survival was low (7.5%), but successful development did occur. At higher manure and moisture levels, rates of development and survival were similar to those reported ...

A sex pheromone isolated from the cuticle and feces of the female house fly attracts the male fly; it has been identified as (Z)-9-tricosene. Chemical and biological comparisons of the natural and synthesized compounds show that they are identical.
