FALLS Interesse besteht werde ich den Hb wieder aktiv weiter fĂĽhren.
Development
A. sexdens, like all ants, has four stages of development: egg, larva, pupa, and adult. They are, like all hymenopterans, haplodiploid, meaning males are haploid (one of each chromosome) and females, including workers, are diploid (a pair of each chromosome). Sex is determined by the type of egg laid. Unfertilized eggs will turn out to be males, which are strictly used for mating and are short-lived. Fertilized eggs produce females. The caste of the resulting adult depends on environmental cues.[citation needed]
Three to four weeks after being laid, the egg hatches and a larva emerges. In Atta ants, the larvae are fed by secretions from gardener-nurse ants and trophic eggs (unfertilized eggs used as food). The larvae, after an additional three to four weeks, spin cocoons around themselves and pupateThe larvae, after an additional three to four weeks pupate. After three to four more weeks, the pupae hatch into adult workers.
A. sexdens larvae grow embedded in the fungal garden. Despite being surrounded by food, they are incapable of feeding themselves. Their adult sisters constantly feed and clean them. This is not a primitive feature. On the contrary, only the most advanced ant societies can expend such lavish care to their offspring as required by Atta larvae.[citation needed]
All eggs are identical when laid. The caste of the resulting worker is determined by the conditions, which are in turn regulated by adult workers. The most important factor is the quantity of food. The largest amount of food results in virgin queens, while slightly less food creates soldiers. A shortage of one caste causes the workers to produce more ants of that caste. A drastic reduction in the work force may cause the colony to revert to the caste structure of a young colony, which does not have soldiers.[citation needed]
Development
Ants in general progress through four stages of development: egg, larva, pupa, and adult. Atta sexdens, like all hymenopterans are haplo-diploid, meaning males are haploid (one of each chromosome) and females are diploid (a pair of each chromosome). Sex is determined by the type of egg is laid. Unfertilized eggs will turn out to be males, which are strictly used for mating and are short-lived. Fertilized eggs produce females.
Three to four weeks after being layed, the egg hatches and a larva emerges. In Atta ants, the larvae are fed by secretions from gardener-nurse ants and trophic eggs (unfertilized eggs that are used as food). The larvae, after an additional 3-4 weeks, spin cocoons around themselves and pupate. After 3-4 more weeks, the pupae hatch into adult workers, ready to serve the queen and colony.
