Females expressing Fad2^{dsRNA.Scer\UAS} under the control of Scer\GAL4¹⁴⁰⁷ show a 27% increase in linear saturated hydrocarbons compared to controls. The amount of dienes and pheromones is decreased by 98%, while that of monoenes is doubled.

Wild-type males show altered courtship behaviour towards females expressing Fad2^{dsRNA.Scer\UAS} under the control of Scer\GAL4¹⁴⁰⁷ compared towards wild-type females; there are 12% fewer copulation attempts and 15% less copulation. Courtship, the first copulation attempt and copulation latencies are increased by 65%, 115% and 55% respectively.

Male and female flies expressing Fad2^{dsRNA.Scer\UAS} under the control of Scer\GAL4^OK72, Scer\GAL4^shn-NP5250 or Scer\GAL4^Lsp2.PH show no difference in the total amount of hydrocarbons compared to controls.

Females expressing Fad2^{dsRNA.Scer\UAS} under the control of Scer\GAL4^OK72 show a large decrease in 7,11-HD (-83%) and 7,11-ND (-85%) and an increase in 7-monoenes compared to controls.

Females expressing Fad2^{dsRNA.Scer\UAS} under the control of Scer\GAL4^shn-NP5250 show a significant decrease in diene percentages in favour of monoenes compared to controls.

Expression of Fad2^{dsRNA.Scer\UAS} under the control of Scer\GAL4^Lsp2.PH has no significant effect on the hydrocarbon profile of female flies.

Expression of Fad2^{dsRNA.Scer\UAS} under the control of Scer\GAL4^OK72, Scer\GAL4^shn-NP5250 or Scer\GAL4^Lsp2.PH has no significant effect on the hydrocarbon profile of male flies.

Wild-type males mated to females expressing Fad2^{dsRNA.Scer\UAS} under the control of Scer\GAL4^OK72 show a decrease in the number of copulation attempts and the courtship index and an increase in copulation latency compared to when wild-type males are mated to control females.
