Which group of insect orders includes both pest and beneficial species that attack pest insect species?

The correct choice highlights the insect orders that encompass both pest and beneficial species capable of targeting other pest insects. Hymenoptera, which includes bees, wasps, and ants, is well-known for having many beneficial species that act as natural predators or parasites of pest insects. For example, parasitic wasps are crucial in controlling aphid populations, showcasing the beneficial aspect of this order.

Thysanoptera, which includes thrips, mainly contains pest species; however, certain thrips can also have beneficial roles in pollination and as biological control agents. Heteroptera consists of true bugs, which include both pests like stink bugs and beneficial species that prey on pests.

This combination of orders is strong in pest management due to the significant roles their members play in both pest control and pollination, highlighting their dual nature as both harmful and helpful within ecosystems.

The other options don't encompass a broad enough range of beneficial predator species alongside pest species to fit the requirement of the question. For instance, Coleoptera includes many pests like beetles but is less known for having beneficial pest control species comparable to those in Hymenoptera. Similarly, the presence of primarily herbivorous orders in the other options limits their effectiveness as predator groups for pest
