我们构建了一个博弈理论模型来预测个体躺在他人巢穴和自己巢穴中的系统中的最佳产卵模式。我们发现，减少产卵序列内的位置对鸡蛋的价值的影响，应导致减少寄生。事实上，只有当蛋对它的生物学父母的价值随着在那个巢中产下的蛋的总数而下降时，寄生才能蓬勃发展。此外，我们发现，增加鸡蛋生产的内在成本应导致同种育雏寄生的倾向增加。该模型还预测，在宿主拒绝寄生卵的能力的变化对寄生的影响很小，直到这种能力得到很好的发展。版权所有2002年。
We constructed a game theoretical model to predict optimal patterns of egg laying in systems where individuals lay in the nests of others as well as in their own nests. We show that decreasing the effect of position within an egg-laying sequence on the worth of an egg should lead to reduced parasitism. Indeed, parasitism can only flourish if the worth of an egg to its biological parent declines with the total number of eggs laid in that nest. Further, we found that increasing the intrinsic costs of egg production should lead to an increased propensity for conspecific brood parasitism. The model also predicts that variation in hosts' ability to reject parasitic eggs has little effect on parasitism until this ability is well developed. Copyright 2002.
