下班前看了一下，如果根据文章想要表达的意思，第一句完全可以省略，这样更简洁。
An underground pest may affect their overground allies through the damaged plants. Here, we used the Vicia faba L to study effects of underground root damage by Bradysia odoriphaga Yang et Zhang on two types of overground color Acyrthosiphon pisum.

在上面的基础上稍微改了一下。
Plants provide a communication network for the underground and overground insects despite their geographic segregation. Hence, an underground pest may affect their overground allies through the damaged plants. Here, we used the Vicia faba L to study effects of underground root feeding by Bradysia odoriphaga Yang et Zhang on two types of overground color Acyrthosiphon pisum.

Our results demonstrated that B. odoriphaga larvae changed the nutrition composition of faba, including fresh to dry weight ratio, soluble protein and saccharide, trehalose, and free amino acids. After feeding of faba leaves from damaged plants, both red and green aphids exhibited an extended nymphal development due to their dramatically prolonged first instar. However, only the red type displayed an increased third instar. Meanwhile, mortality rates elevated on both types of aphids compared with their control groups. The green nymphs had a higher mortality rate on the first and second instar while the reds increased on the second, third, and forth instar. Further, both types of color aphids showed trends to increase their average generation time and significant decreases in multiple aspects, such as daily offspring production, accumulated nymphs of 10 days per female, net reproductive rate, intrinsic rate of increase, finite rate of increase, relative growth ratio, body length and weight.

Conclusion：
The changes on the growth and development of pea aphids suggested an indirect negative effect of B. odoriphaga through the damaged faba plants.
