Quando estás quente, exageras no perfume logo fico inibido e não te polinizo.

Assim como não quer a coisa, o Figueiras enviou um enigmático mail à Teresinha: " Each day, between 11am and 3pm, the temperature of the cones, particularly the male ones, shoots up by more than 12 degrees. The increase in temperature makes the cone uncomfortable for the thrips. It`s also accompanied by a million-fold surge in the production of an odorous chemical called beta-myrcene. At low levels, thrips find the smell attractive, which helps to lure them, but at higher concentrations it smells repugnant and drives them out. The insects then abandon their feast and seek refuge in the surrounding bushes. But by mid-afternoon the cones have cooled again, and the concentration of beta-myrcene drops, encouraging the thrips to return, along with their pollen. And since the male and female cones both look and smell alike, the insects flock back to both, carrying pollen into the female cones and fertilising them." O desfecho foi contrário ao esperado pois a Teresinha nunca mais lhe falou.
