Females lay their eggs in necrotic material
So, my guess is that the necrotic decomposition phase is able to host all life cycles of the eggs. However, why do they still lay eggs on fresh items and food if it has not started through the decomp phase?
From its first use in the laboratory in the early 1900s until the present day, Drosophila melanogaster has been central to major breakthroughs in genetics.
I had no clue how big of a role the fruit fly plays in genetic research. As i read more, I find out just how much they are studied in the lab versus in the wild.
holometabolous,
Other insects that are considered holometabolous include some common ones such as: house flies, mosquitoes, gnats, monarch butterflies and some moths. Both the larvae and adults occupy the decaying source at different time frames which allows the interactions between the microbes.
D. melanogaster do not live alone. Their decaying host resources are also home to many microbes, as well as to other arthropods, including other Drosophila species, all of which they interact with (see Video 1, 2). Some microbes in the decaying material themselves provide food for D. melanogaster, being selectively consumed by larvae or adults
The microbes not only live in this environment, but also serve as a food source for the flies. This explains how the D. melanogaster depend on other organisms in their habitat.
We hypothesize that these dynamic interactions, coupled with the potentially high metabolic cost of toxins (Nisani et al., 2012), have driven the evolution of a distinct venom composition in each developmental stage.
Interesting when reading up on this particular section, each pupal phase creates its own set of venom mixtures which helps it to balance energy and stay protected!
recombinant form
This refers to the biological molecule which is usually RNA, DNA or protein that is combined artificially from different sources. It is considered genetic engineering.
