时态疑问：句中应该用动词bite还是bites

When there is an allergic reaction or when insects like mosquito bite, the itch receptors of that region send itch signals to the brain.

句中应该用bites吗？ 即when insects like mosquito bites ?

when insects like mosquito bite

你不想一想，主语是什么名词？mosquito为可数名词，这里用单数为错误，应该为复数。但主语insects为复数，mosquito单数错误也不影响谓语动词用复数形式。

你犯的是低级错误。
