1.通过对1973、1974和1975年受害果样品数据的分析,取得了油橄榄实蝇未熟期的抽样技术(未熟期系指卵期和幼虫期译者注)。2.要求达到一定精确度的样品的数量基本上是一个密度的函数,因此已知油橄榄实蝇未熟期的密度,就可大体确定抽样的数量。3.部分生命表是由油橄榄实蝇连续世代的主要发育期构成,一年的大部分时间产卵的数量,而不是死亡率,决定产生蛹数的多少。4.在9月第3龄幼虫死亡率很高,主要是由于寄生现象,寄生相当大地减少了这段时期产生的蛹数。
1. Through the analysis of the data of victim fruit samples in 1973, 1974 and 1975, the sampling technique of immature fruit fly was obtained (immature refers to the translator note in the egg and larval stages). 2. The number of samples required to achieve a certain degree of accuracy is essentially a function of the density, so that, given the immature phase density of the fruit fly, the number of samples can be generally determined. Part of the life table is composed of the main developmental stages of successive generations of the genus Olea europaeus. The number of spawning, but not the mortality, most of the year depends on the number of pupae. 4. The third-instar larvae mortality was high in September, mainly due to parasitism, and parasitism considerably reduced the number of pupae produced during this period.
