In it, the authors argue that insects provide a plausible and effective explanation for the slow, inexorable decline and eventual extinction of dinosaurs over many thousands of years. This period is known as the famous “K-T Boundary,” or the line between the Cretaceous and Tertiary Period about 65 million years ago. There is evidence that some catastrophic events, such as a major asteroid or lava flows, also occurred at this time — but these provide no complete explanation for the gradual decline of dinosaur populations, and even how some dinosaurs survived for thousands of years after the K-T Boundary.

最近科学界对恐龙绝种有一项新的理论，不是因为流星或火山爆发，而是因为昆虫的原因。这个理论说起来也合理，因为恐龙不是在短时间内灭绝的，而是经过好长一段时间才逐渐消失。专家指出这可能是因为昆虫的攻击，以及病毒的传播而导致恐龙绝种。当然昆虫不一定是唯一的原因，要造成一个物种的灭绝自然有很多其它的因素。昆虫在地球生物的进化过程中也扮演了很了不起的角色。
