杨鹏长难句X1

Namelessone~UID: 3111489

Since large bees are not affected by the spraying, these results add weight to the argument that spraying where the pollinators are sensitive to the pesticide used decreases plant fecundity.

杨鹏译：由于大蜜蜂不受喷洒杀虫剂的影响，这些结果增加论点力度，该论点是在传粉昆虫对杀虫剂敏感区域喷洒杀虫剂，会减少果实的结识性。

有两个疑问：
1、大蜜蜂不是不受影响吗？怎么还是“decrease”的效应？
因此，原句是否该理解为“因为不受影响，所以增加一个论证力度，即‘blabla会decrease sth’”   (此处argument应指对某一观点的争论辩驳，而不是“论点”-一个观点)
2、plant fecundity 不是“植物的产量”吗
--
请教这两点，是我理解有误，还是翻译错了。多谢。

文章讲的是对杀虫剂敏感的传粉昆虫会在被喷杀虫剂后，花会减产

研究讲到减产大部分发生在用小蜜蜂和某一类苍蝇来传粉的植物中
然后讲了2中植物
其中一种就是和这句话相关的植物，用大蜜蜂来传粉的，没有减少产量
因为大蜜蜂不受杀虫剂影响（即对杀虫剂不敏感），所以这个证据也就支持了上面的观点，杀虫剂敏感的传粉昆虫会在被喷杀虫剂后，花会减产

Species interdependence in nature confers many benefits on the species involved, but it can also become a point of weakness when one species involved in the relationship is affected by a catastrophe. Thus, flowering plant species dependent on insect pollination, as opposed to self-pollination or wind pollination, could be endangered when the population of insect-pollinators is depleted by the use of pesticides.
　　In the forests of New Brunswick, for example, various pesticides have been sprayed in the past 25 years in efforts to control the spruce budworm, an economically significant pest. Scientists have now investigated the effects of the spraying of Matacil, one of the anti-budworm agents that is least toxic to insect-pollinators. They studied Matacil’s effects on insect mortality in a wide variety of wild insect species and on plant fecundity, expressed as the percentage of the total flowers on an individual plant that actually developed fruit and bore seeds. They found that the most pronounced mortality after the spraying of Matacil occurred among the smaller bees and one family of flies, insects that were all important pollinators of numerous species of plants growing beneath the tree canopy of forests. The fecundity of plants in one common indigenous species, the red-osier dogwood, was significantly reduced in the sprayed areas as compared to that of plants in control plots where Matacil was not sprayed. This species is highly dependent on the insect-pollinators most vulnerable to Matacil. The creeping dogwood, a species similar to the red-osier dogwood, but which is pollinated by large bees, such as bumblebees, showed no significant decline in fecundity. Since large bees are not affected by the spraying of Matacil, these results add weight to the argument that spraying where the pollinators are sensitive to the pesticide used decreases plant fecundity.
　　The question of whether the decrease in plant fecundity caused by the spraying of pesticides actually causes a decline in the overall population of flowering plant species still remains unanswered. Plant species dependent solely on seeds for survival or dispersal are obviously more vulnerable to any decrease in plant fecundity that occurs, whatever its cause. If, on the other hand, vegetative growth and dispersal (by means of shoots or runners) are available as alternative reproductive strategies for a species, then decreases in plant fecundity may be of little consequence. The fecundity effects described here are likely to have the most profound impact on plant species with all four of the following characteristics: a short life span, a narrow geographic range, an incapacity for vegetative propagation, and a dependence on a small number of insect-pollinator species. Perhaps we should give special attention to the conservation of such plant species since they lack key factors in their defenses against the environmental disruption caused by pesticide use.
