Parasitoid insects are veritable serial killers, and they play a major role in the regulation of insect populations. Scientific research on the lines of a criminal investigation reveals how these killers behave and what remarkable capabilities they have. In basic research, parasitoids make excellent models for behavioral ecology studies. They are also used in applied research, notably for biological control, where they can serve as precious auxiliaries for controlling crop pests. Parasitoids still have many secrets to reveal, and new research avenues are opening up.

Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the Cyclops is swept over a waterfall and becomes trapped inside a plastic bottle, which turns out to be the ideal place to observe aquatic insects inhabiting the white water of the rapids. Part 8 of the Microscopic Monsters Series.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this clip, the Micronauts explore the vast populations of filter feeders in the open waters of ponds. While exploring, they must escape the powerful feeding currents of these filter feeders. During this adventure, they also explore the special adaptations of algae and water fleas. Part 1 of the Microscopic Monsters Series.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the Cyclops is washed out of the pond and tumbles into a rapidly flowing stream. In the rapids, they discover aquatic insects living under rocks. Through their careful observations, the Micronauts learn the insects are adapted for living on water-swept rocks. Part 7 of the Microscopic Monsters Series.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the crew continues to observe a variety of bacteria. They discover that bacteria is the food of choice for large single celled protists in the pond. Their observations lead them to make conclusions about the food chain found in the pond. Part 6 of the Microscopic Monsters Series.
There’s been a lot of research on what happens to a river when dams are built, but what happens when a dam is torn down? With support from the National Science Foundation, Dartmouth College geographer Frank Magilligan is researching the impact of dam removal. His lab has been at the relatively small Homestead Dam, built more than 200 years ago along the Ashuelot River in New Hampshire. He and his team have collected data on the ecology and geology of the Ashuelot River both before and after the Dam removal. Now, they’ll be documenting the processes of ecological restoration and how the path of the river is changing.
One of the oldest, most successful arthropods on Earth, horseshoe crabs have existed for over 350 million years. But in recent years their populations, have crashed by 75% from overfishing, resulting in moratoriums on catching them. Few of us know that most human lives depend on the valuable, shockingly blue blood of these "living fossils." Even more surprising, a tiny shore bird, the red knot, is so dependent on them that the crabs' population crash may make these long-distance flyers extinct. This mystery of mutual dependencies emerges from filmmakers and scientists revealing a disturbing ecology story ranging from the Arctic regions to the southern tip of the Americas.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the Cyclops crashes into the bottom of the pond and discovers an ooze populated by bacteria. After gathering some, the Micronauts begin to investigate the chemical method the bacteria uses to decompose organic material. In the end, the bacterial also helps the crew escape the bottom of the pond so they can continue to explore. Part 5 of the Microscopic Monsters Series.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. While navigating the dense aquatic weed forest of the pond, the Cyclops is pulled off course by a hydra. After escaping its tentacles, the crew begins to study how the hydra reproduces, captures its food, and digests its prey. One of the Micronauts takes a journey inside the hydra’s digestive system to get a first-hand account of the digestive process. Part 4 of the Microscopic Monsters Series.
