22 Questions
Which order consists of insects that are exclusively predatory?
Odonates
What is a common characteristic of sit and wait predators?
They are camouflaged.
How do parasitoids typically lay their eggs on or in their hosts?
By using specialized ovipositors
What is the main difference between traditional predators and parasitoids?
Parasitoids develop into larvae inside or on the host.
Which development stage of a parasitoid kills the host?
Larva
What is one way insects can prevent parasitoid encapsulation?
Melanizing immune cells to thicken them
What is an exclusive or mostly parasitic species found in many orders?
Strepsiptera
How do Strepsiptera females signal to flying males?
By releasing pheromones
What is the unique behavior of Strepsiptera males during pupation?
They leave the host
Why do females of Strepsiptera never pupate?
They remain as larva-like insects
What is the main factor that drives army ants to move often?
Depletion of food supply
What is the primary mode of communication among blind driver ants?
Pheromones
Which type of ant has queens that are the largest of all ants?
Driver ants
How do army ants forage for food when they dissolve their bivouac?
Foraging columns
What is the predominant strategy employed by army ants while attacking social insect nests?
Swarming
In what way do new queen ants contribute to colony growth?
By laying eggs
What role do hyperparasitoids play in the ecosystem?
They help control pests by feeding on primary parasitoids.
How do dipteran parasitoids differ from hymenopteran parasitoids in host finding?
Dipteran larvae sometimes have morphological modifications for host finding.
What is the main method used by hymenopteran parasitoids to immobilize their hosts?
Using a stinger
In what way do avoidance and suppression differ in relation to parasite-host interactions?
Avoidance hangout triggers encapsulation while suppression interferes with it.
What distinguishes subversion from destruction in terms of host-parasitoid interactions?
Subversion is when the parasitoid is encapsulated but tolerates it, whereas destruction weakens the host.
Why are hymenopteran and dipteran parasitoids considered important selective agents?
They are involved in evolutionary arms races with their hosts.
Explore the concepts of predation, parasitism, parasitoids, and scavengers in insects through an outline of a lecture by Professor Johnson. Learn about the different roles these organisms play in ecosystems and their unique hunting or feeding behaviors.
