Lecture-21-23 Life in the Undergrowth Episode 4

Video: Life in the Undergrowth: Episode 4: Intimate Relations

Ever since they came onto land, the tiny creatures of the undergrowth have been forming alliances and partnerships with each other and with plants. Many of these relationships are staggeringly complex. While some clearly benefit both partners, others most certainly do not. Meet the bot fly which uses smaller house flies as unwitting couriers to carry its eggs to cows, where they hatch and bore into the unsuspecting animal's flesh.

Lecture 21-22 Insects as Food for Humans

Aubrey Moore — Wed, 10 Nov 2021 02:45:00 GMT

Marcel Dicke wants us to reconsider our relationship with insects, promoting bugs as a tasty — and ecologically sound — alternative to meat in an increasingly hungry world.

Video: Life in the Undergrowth 3. The Silk Spinners

Silk is the secret weapon of the undergrowth. From the protective stalks of lacewing eggs, to the hanging threads of glow-worms, insects use it in an amazing variety of ways. Silk is stronger than a steel thread of the same diameter but, unlike steel, it's elastic. Witness the spiders who have taken the use of this extraordinary material to its extremes.

Lecture-21-17 Review for EXAM2

Aubrey Moore — Mon, 25 Oct 2021 02:45:00 GMT

Topics Covered Since Exam 1

Chemical ecology

Insects rely heavily on semiochemicals to get information from the environment.
Insects use pheromones for intraspecific communication. There are many types of pheromones: sex pheromones, aggregation pheromones, alarm pheromones, trail-following pheromones, etc.
Synthetic pheromones extensively in insect pest control for monitoring, population reduction (attracticides), and mating disruption.
Insects use kairomones for finding food: host plants, nectar, prey and host insects.

Mimicry and Camouflage

Batesian mimicry: a non-harmful species (mimic) has evolved to look like a harmful species (model)
Mullerian mimicry: two or more unrelated noxious, or dangerous, organisms exhibit closely similar warning coloration (usually patterns often yellow, red and black stripes)
Camouflage

Population dynamics

Exponential model
Logistic model
Carrying capacity (k): maximum population size that can be sustained by the environment
r-selected and k-selected species
Lotka-Voltera model for population dynamics of interacting species

Invasive species

An invasive species is alien and causes harm.
Invasive species readily establish on tropical islands because they have "escaped from natural enemies", weather is benign (no winter, high humidity), and there is usually plenty of food and water.
Fifty percent of Guam's invasive insects belong to Order Hemiptera.

Applied entomology

Pest control based solely on pesticide application is limited because of pesticide resistance and nontarget effects.
Integrated pest management (IPM): one or more pest control tactics are selected based on knowledge of the current situation gained from pest monitoring.
IPM tactics include pesticide application, sanitation, biological control, physical control, cultural control, and "do nothing".
Economic threshold level (EIL): the population density at which pest control should be initiated to prevent economic damage.
If possible, broad spectrum pesticides should be avoided because they may kill beneficial insects which will lead to an uncontrolled resurgence of pests.
