Discriminative host sanctions in a fig-wasp mutualism by Wang, Rui-Wu, Dunn, Derek W, Sun, Bao Fa

“…In some mutualisms, cooperation in symbionts is promoted by hosts sanctioning "cheats," who obtain benefits but fail to reciprocate. In fig-wasp mutualisms,…”

Egg load is a cue for offspring sex ratio adjustment in a fig‐pollinating wasp with male‐eggs‐first sex allocation by Zhang, Xiao‐Wei, Dunn, Derek W., Wang, Rui Wu

“…Fig‐pollinating wasps (Agaonidae) only reproduce within fig tree inflorescences (figs). Agaonid offspring sex ratios are usually female‐biased and often concur…”
