Abstract

A series of experiments was carried out in controlled environment cabinets to investigate the effects of SO(2) dose on the mean relative growth rate (MRGR) of pea aphids, Acyrthosiphon pisum, feeding on the pea plant, Pisum sativum. There was a significant linear increase in the MRGR of aphids feeding on SO(2)-fumigated plants, relative to control aphids feeding on plants in charcoal-filtered air. The increase in MRGR reached a maximum of 11% at SO(2) concentrations between 90 and 110 nl litre(-1). MRGR declined at higher SO(2) concentrations until above 220 nl litre(-1) it was below that of the controls. The dose-response curve is discussed in relation to reported changes in the nitrogen metabolism of plants subject to air pollution, the response of aphids to host plant nitrogen and possible toxic effects of high concentrations of SO(2) on the aphid.

摘要

在可控环境箱中进行了一系列实验，以研究二氧化硫剂量对以豌豆（Pisum sativum）为食的豌豆蚜（Acyrthosiphon pisum）平均相对生长率（MRGR）的影响。与在经过活性炭过滤空气的环境中取食植株的对照蚜虫相比，取食经二氧化硫熏蒸植株的蚜虫的平均相对生长率有显著的线性增加。在二氧化硫浓度为90至110 nl升⁻¹之间时，平均相对生长率的增加最大达到11%。在更高的二氧化硫浓度下，平均相对生长率下降，直到超过220 nl升⁻¹时低于对照。结合已报道的受空气污染植物氮代谢的变化、蚜虫对寄主植物氮的反应以及高浓度二氧化硫对蚜虫可能的毒性作用，对剂量反应曲线进行了讨论。
