In this series, learn a bit more about who these entomologists are, what inspired them to get into the field, and discuss some of their most recent research.https://talking-bugs.captivate.fmnoepisodicBiological Control with Dr. Gerben Messelink, Wageningen UniversityBiological Control with Dr. Gerben Messelink, Wageningen UniversityDr. Messelink is a Special Professor in Biological Pest Control in Greenhouse Production Systems and Senior Research Entomologist at Wageningen University in the Netherlands. He has an extensive background in conducting research using predators and parasitic wasps to manage common pests in greenhouse production.

We discuss one of his recent publications looking at using a generalist predator to manage two key pests (whiteflies and thrips) on gerberas.

Dr. Anjel Helms, Chemical Cues in Plant DefensesDr. Helms investigates questions regarding chemical cues between predators, herbivores, and their plants, and how their interact both below and above-ground. In this interview, we learn more about a specific study that looked at how chemical cues from a below-ground predator could potentially 'prime' plant defenses against above-ground herbivores.

He made his way there through studying plant viruses that are vectored by insects. In this episode, we learn about what motivated Dr. Rydzak, how he learned about opportunities to work for the F.B.I., and his recent research that used a combination of multiplex PCR and high-resolution melting to discriminate between several viruses found in cereals.

Using a technique referred to as electrical penetration graph or electropenetrography, sucking insects are integrated into a low-voltage circuit. Upon feeding, the insect completes the circuit and different electrical signal patterns indicate different types of feeding behavior.

Dr. Brent Sinclair is known for his research in low and high temperature tolerance of arthropods, such as fruit flies and crickets. Some insects can tolerate being completely frozen and thawing out alive, whereas others cannot. This is the second part of a two-part episode with Dr. Sinclair.
