Mothers use sex pheromones to veil eggs, preventing cannibalism

Species that lay eggs but don't actively keep watch over them often protect their precious eggs from predators by laying them in communal groups or by fortifying them with toxins. However, protecting these eggs from being devoured by their own kind is a completely different game; the catch is that any anti-cannibalistic strategy needs to be an effective deterrent while remaining nontoxic to the cannibals. In a new study published in the open-access journal PLOS Biology on January 10, Sunitha Narasimha, Roshan Vijendravarma and colleagues report how fruit flies (Drosophila melanogaster), which lay eggs communally, use chemical deception to protect their eggs from being cannibalized by their own larvae.

In a new study published in the open-access journal PLOS Biology on January 10, Sunitha Narasimha, Roshan Vijendravarma and colleagues report how fruit flies (Drosophila melanogaster), which lay eggs communally, use chemical deception to protect their eggs from being cannibalized by their own larvae.

Using a multidisciplinary approach, Dr. Roshan Vijendravarma from the Department of Ecology and Evolution, University of Lausanne, Switzerland (currently at Institut Curie, Paris, France) and his team of international collaborators teased apart the chemical, sensory, genetic and mechanistic basis of deception using the Drosophila model system.

The team was intrigued by the observation that fruit fly larvae, despite their predatory nature, seldom attacked eggs in their vicinity even when deprived of food. While testing for various plausible defense mechanisms, the researchers found that the extremely thin wax layer within the egg shell acts as a protective barrier that prevents cannibalism.

Using high-resolution mass spectrometry to identify the specific molecules involved, the team discovered that the wax layer is composed of a bouquet of sex pheromones originating from both parents, and then nailed the protective effect on a female chemical called 7,11-heptacosadiene (7,11-HD); this pheromone, normally used to spice up the adult flies' mating, was incorporated into the egg's wax layer by the mother.

It was already known that the adults need a gene called ppk23 for detecting the 7,11-HD pheromone during mating, so the authors looked to see whether the ppk23 gene played an analogous role in the larvae. They found that the gene was indeed involved in detection of this pheromone in larvae "a different developmental life-stage" but modulates an entirely different behavioral outcome.

Finally, this nontoxic pheromone had an interesting property whereby a coating of 7,11-HD could mask the identity of underlying substances from larvae—even yeast, normally irresistible to fly larvae. In the egg, these maternal hydrocarbons incorporated within the wax layer leak-proofed the egg to prevent desiccation, and by doing so additionally serve as a mask that conceals the egg's identity from cannibal larvae.

the life of a grass sniffer

I just about swoon over the scent of fresh cut grass.. as morbid as that may sound..  with the right perspective, it becomes quite a meaningful(and beautiful) experience... What we smell after mowing the yard are a few out of a handfull of pheramones known as green leaf volitiles (GLVs). They are released when when the blades of grass are damaged, acting as a message to other plants nearby, warning them of the potential danger.  This in turn causes the surrounding flora to change their metabolic state in order to be prepared to protect themselves, should they end up damaged. That smell is a chemical language..  complete with something of an atomic syntax..  the stronger tge scent, the louder the voice.. Plant life is amazing like this.. that fresh cut grass is literally screaming for my bliss.
