桃树蚜虫越冬卵空间分布规律

2006年以来．在桃树害虫综合治理的实践中发现，桃树蚜虫越冬卵分布很不均匀。为此，从桃树蚜虫越冬卵的分布入手进行了认真细致的调查，把桃树赤蚜、桃粉蚜、桃瘤蚜3种越冬卵作为1个混合体进行研究。并运用生物数学的方法进行运标统计，得出桃蚜越冬卵呈聚集型分布。为桃树蚜虫的测报和防治提供了科学的依据。

The spatial distribution laws of aphids'eggs in peaches living through out the winter

We’ve found out that aphids’eggs in peaches living through winter dirstribute unevenly since we began to synthetically deal with pests in peaches in 2006.We’ve made a careful inverstigation into the distribution of the aphid eggs in peaches living through winter and also carried out standard statistics by the method of biomathematics.Thus,we conclude the distribution of aphid eggs in peaches living through winter.We worked out the scientific basis for prediction and control of aphids in peaches.
