In the lifespan assays, we also observed similarly prolonged survival of Tau*C2A (mean lifespan about 60 days) and Tau*S2A flies (mean lifespan about 63 days), when compared with Tau flies (mean lifespan about 30 days).
We discovered that while perching on plants, the male flies emit large quantities of a putative sex pheromone, attractive to female flies (mean ~70±2020 μg 24 h−1; [ 15]).
Since PG flies were smaller than FG flies (mean ± SD weight, 70.8 ± 2.2 mg and 129.2 ± 3.8 mg, respectively), we supplied PG males with two PG flies to provide approximately the same mass of prey.
Fifty L1 larvae were placed in a vial and a tally made of all fully eclosed adult flies, mean values were calculated and plotted as a percentage of the total number of larvae picked.
Fifty first instar larvae were placed in a vial and a tally made of all fully eclosed adult flies, mean values were calculated and plotted as a percentage of total number of larvae picked.
Being rigged for silent flying means they can also hear their prey better.
With most airspace under military control and little spare capacity in civilian airspace, getting permission to fly means applying up to five days in advance, which rather undermines a big reason for owning a private jet, namely greater flexibility.
That makes it far cheaper to run than a plane of equivalent size, while the fact that it is flying means it is far faster at 80-100 knots—than a ship of any size.
Lars von Trier drives from his home in Denmark to the Cannes film festival every year, and his refusal to fly means that all his films – even those ostensibly set in America – are filmed in Denmark or Sweden.
