人工繁殖天敌释放到田间后的生存率估计

Estimation on field survival of artificial released natural enemies.

针对人工繁殖释放的天敌在田间的生存率等问题进行建模 ,提出了一种研究天敌生存率的着色标记统计方法 ,应用 L ogistic线性模型给出了不同性别和年龄天敌生存率的极大似然估计 。

Based on color marking approaches, survival models of artificially released natural enemies in the field were constructed. Using logistic linear models, maximum likelihood estimations of survival probabilities of natural enemies of different gender and different age were provided. The methodology is a sound foundation for determining the optimal numbers of natural enemies to achieve the effective control of target pests in the field.
