“…The amounts of (Z)-9-tricosene on males gradually increased and those on females decreased in the course of time, which suggests that transfer of (Z)-9-tricosene from females to males took place due to physical contact between the sexes. This agrees with the results of Ahmad et al (1989) who showed that during copulation an average of 4.1% topically applied radiolabelled (Z)-9-tricosene on the abdomen of a female was transferred to the body of a male. A similar effect can be observed for the most abundant hydrocarbon in males, (Z)-9-heptacosene.…”

Using gas chromatography the relative amounts of (Z)‐9‐tricosene (muscalure) and some other hydrocarbons on the cuticle of 1‐ to 20‐day‐old houseflies (Musca domestica L.) from different strains were determined. Flies from a WHO strain, in culture since 1961, and first‐generation laboratory‐cultured flies from two wild‐type strains from a poultry breeding and a cow‐house with pigsty, respectively, were compared. On WHO females hydrocarbons with 23–25 C atoms constituted about 65% of the total hydrocarbons, whereas on wild‐type females less than 2% of these compounds was present. (Z)‐9‐tricosene comprised up to 20–30% of the total hydrocarbons on 5‐ to 20‐day‐old WHO females, whereas less than 0.5% (Z)‐9‐tricosene was present on the wild‐type females. We also compared the amounts of (Z)‐9‐tricosene and some other hydrocarbons on female houseflies, kept in culture in the laboratory for several generations. It appeared that whereas on first‐generation wild‐type females hardly or no (Z)‐9‐tricosene could be detected, the amounts of this substance had increased considerably after some tens of generations in the laboratory. It is suggested that this was due to selection in subsequent generations of high‐density populations. Production of (Z)‐9‐tricosene and of tricosane was shown to be closely linked. Selection did not affect the production of other cuticular hydrocarbons by the females. It is suggested that in mixed populations (both sexes together in a cage) in the course of time (Z)‐9‐tricosene is transferred from females to males and (Z)‐9‐heptacosene from males to females. It is concluded that reproductive ability of houseflies does not primarily depend on the amounts of (Z)‐9‐tricosene on females, although higher amounts of this substance may increase contacts between males and females.

“…The virulence in our study also seemed greater than that recorded in a recent study where 10 Mexican fungi isolated from soil of dairy farms were tested by aspersion at a dose of 1×10 Although females might be infected by conidia from the inside of the chambers, unknown amounts of conidia also might have been transferred from males to females during the long copulations exhibited by M. domestica. Copulation by a healthy male lasts an average of 90.5 ± 21.8 with a range of 30-145 minutes (Ahmad et al 1989). An earlier study also confirmed that a female that copulated less than 30 minutes required additional mating (Murvosh et al 1964).…”

“…The greatest increase was observed in populations from California, where the mean daily temperatures are higher and the humidity is much lower than Minnesota or Georgia. Studies with colonized, laboratory-reared house ßies (that have more uniform and higher levels of muscalure relative to wild ßies) have demonstrated this increase with age (Dillwith et al 1983, Ahmad et al 1989, Mpuru et al 2001, Darbro et al 2005), but to our knowledge, this is the Þrst Þeld study to do so. Ahmad et al (1989) determined an increase in (Z)-9-tricosene content from Ͻ1 g in 2-d-old colonized females to 4 g in 6-d-old females.…”

Gonotrophic Development and Survival in Field Populations of <I>Musca domestica</I> (Diptera: Muscidae) at Dairies in California, Minnesota, and Georgia, and the Relationship of Fly Age to Relative Abundance of (<I>Z</I>)-9-Tricosene (Muscalure)

Adult female Musca domestica L. were collected in 2004 and 2005 from dairies in California, Minnesota, and Georgia. Relative abundance of (Z)-9-tricosene (muscalure) among the dominant eight hydrocarbons was determined. Fly heads then were removed to quantify pterin levels and estimate fly age, abdomens were dissected to score gonotrophic development and parity (follicular relics), and spermathecae were examined for sperm. Daily survival was assessed using two estimates of time required to become gravid: laboratory-based degree-day (DD) estimates and estimates based on pterin values in field-collected flies matched to their stages of gonotrophic development. Among newly emerged females (oocyte stage 1) with detectable muscalure, it comprised < approximately 1.5% of cuticular hydrocarbons. In muscalure-positive flies, muscalure comprised a higher proportion of cuticular hydrocarbons in older flies from California and Minnesota (6-9% when gravid) versus flies from Georgia (<2% when gravid). Females mated in early-intermediate stages of egg development. Life expectancy, using laboratory-derived estimates of time needed to become gravid, ranged from 3.6 to 10.6 d. Using equivalent pterin-based time estimates, life expectancy ranged from 4.0 to 19.5 d. Mean DD ages (12 degrees C threshold) of gravid flies varied widely (53-95 DD) and were congruent with laboratory-based estimates (52-57 DD) in only 7 of 12 farm-year combinations. Thus, house flies under natural conditions often required more time to develop eggs than laboratory models would predict, extending daily survival estimates based on gonotrophic age by 11-74%.
