Ranked by relevance and common usage.
Keep "siblicide" when the sentence already sounds natural, when a synonym would add unintended emphasis, or when readers need the most familiar wording. A synonym should clarify or sharpen the message, not simply make the sentence look more varied.
If two options seem close, choose the one that best matches the audience and purpose of the sentence.
Choose a synonym only if it keeps the core idea of "siblicide" intact in the sentence you are editing.
Check whether the replacement sounds more formal, casual, emotional, technical, or forceful than the original word.
Read the full sentence after the swap. Keep the synonym only when the sentence becomes clearer or more precise.
Review note: Synonym lists are ranked with lexical data and reviewed for practical writing value. Use the comparison notes, sentence evidence, and source labels together; a high-ranking synonym can still be wrong when the audience, register, or grammar changes.
After choosing a replacement for "siblicide", read the sentence once for meaning and once for rhythm. The best synonym should feel natural in the full sentence, not only accurate in a word list.
If the synonym makes the sentence slower, vaguer, or more dramatic than intended, keep "siblicide" or choose a simpler alternative from the closest-match group.

I still have not seen data to support "siblicide" as a strategy.

[…] Adelphophagy, literally eating one's brother, is also known in sharks as intrauterine embryonic cannibalism[…].

Obligate siblicide is best known in various eagles, boobies, and pelicans. All lay two eggs, hatching is asynchronus, and usually the elder sib kills its younger sib soon after hatch. From the parent's perspective, the second egg/chick serves as insurance against the unexpected failure of the first[…]. Interestingly, obligate siblicide seems to be independent of prevailing food at the time of the junior sibling[']s demise.

If siblicides are victim-based, a mother clearly cannot improve her fitness by producing fewer eggs. Less obviously, mothers may eventually be able to gain by laying more, until eventually they are constrained by the costs of eggs.
