Abstract The juxtaposition and functional relationship of the sperm storage organs in Anastrepha ludens (Loew) is described. The spermatheca squash technique has been used to determine mated status in tephritid fruit flies, and thus as a measure of compatibility and coverage for sterile insect technique programs. Female A. ludens have four seminal storage organs: three spermathecae and a ventral receptacle. By interrupting coitus at set intervals, it is shown that the ventral receptacle fills first and after 15–30 min the spermathecae begin to fill. Among wild captured flies, all mature (gravid) females had semen in the ventral receptacle, but only 40 – 60% had sperm in at least one spermatheca. Therefore, examination of the ventral receptacle rather than the spermathecae alone is the more reliable method for determining mated status.

Ranked by citation count — the same ordering the engine uses when summing log1p(Cq) over citers.
DataRank blends this paper's own citation count with the influence of the papers that cite it. Here, roughly 55% comes from its base citations and 45% from the citation network (9 citing papers contributed measurable signal).
Citers are pulled from OpenAlex sorted by cited_by_count:descand capped per paper, so when the cap binds we keep the highest-signal references and the score is reproducible across reruns.
