Entomology Study Guide 2007 Insect structure and life histories What are the other major classes in the Arthropoda Compare their tagmosis with that of insects What are the major innovations that occurred during the evolution of the Insecta How do these relate to the phylogenetic tree of the insect orders Contrast hemimetabolous and holometabolous life histories What are the advantages and disadvantages of each What are the components of insect cuticle What parts of the body would make use of rigid cuticle Of exible cuticle What events occur during molting in insects and how do hormones control molting and metamorphosis Insect Physiology What is the structure and function of the respiratory systems in insects and how has this impacted the structure and function of the circulatory system What is the role of the circulatory system in thermoregulation For example during ight on warm or cool days in moths or for brooding young in bumblebees How is the digestive system of insects adapted for dealing with different types of food eg liquid versus solid and plant versus animal What is the structure of generalized insect mouthparts and how have they been modified for different diets For example the sucking mouthparts in bugs and mosquitoes or the siphon mouthparts of Lepidoptera Explain the roles of the Malpighian tubules and hindgut in insect excretion Reproduction What are the differences between R and K strategies in insect reproduction and give a good example of each What are the functions of the different components of the male and female reproductive tracts What are some physiological and behavioral adaptations developed by insects that show parental care of their young Insect Diversity What are the characters that distinguish the immature and adult stages of the major orders of insects What is the benefit for aphids to shift between sexual and parthenogenetic strategies How is sociality manifest in aphids and thrips What do the eusocial species in these very different orders share in common How can beetles like bombardier beetles make defensive sprays that are extremely toxic or hot without either poisoning or cooking themselves How do bark beetles overcome the defenses of trees What are differences between the adults and larvae of the Apocrita versus the Symphyta What is meant by polyembryony and why aren t all of the members of the clone identical What is the defining difference between a butter y and a moth Insect Sensory Systems How do insect mechanoreceptors work and how are they used for making a complex sensory structure such as an ear What is the structure and function of the main types of sensory receptors visual mechanosensory olfactory in insects Discuss the roles of light sound and odor in insect communication Provide an example of how each is exploited to the detriment of the sender Insect Flight Provide a possible hypothesis for the evolution of wings in the insects In the context of flight know the relationship between muscle contraction thorax movement and wing movement Also the difference between synchronous and asynchronous systems How have different orders modified their fore and hind wings Diapause and Migration What are the strategies that diapausing insects use to avoid being killed by freezing temperatures in the winter What characterizes homeostatic versus dynamic migration Know how to interpret a photoperiodic response curve Discuss the relationship between reproduction and migration in insects The Cleanup crew What insects are diagnostic for different phases of succession on dead animals What is the structure of termite societies and how is the proper composition of castes maintained Compare the problems of insects involved with removing bodies and waste from animals versus plant bodies e g logs Predators and Parasites What are some of the major strategies used by predatory insects and provide examples of each What are some of the strategies that parasitoids use to overcome the defenses of their hosts Insects that slam into spider webs are not always caught Give an example of how an insect might avoid being captured and then of a spider that has devised a way around this defense Plantinsect Interactions What are the types of beneficial interactions between insects and plants giving the benefits to both partners and the adaptations each show to facilitate this mutalism How might one of the partners cheat What is the special relationship between fig wasps and figs Why would a plant have an extrafloral nectary Insects and agriculture What factors could cause a particular insect species to become a pest How do economic thresholds and economic injury levels relate to insect control strategies How does traditional Bt work and why is it selective to lepidopteran caterpillars What are the advantages and disadvantages of GM plants such as Bt corn as a strategy for insect control Which do you consider the most serious Social Insects What defines eusociality What are factors that favor its evolution Compare sociality in bees and ants Medical Entomology How are fleas involved in the dissemination of plague Discuss the interaction between insect pathogen and host for either malaria sleeping sickness or filariasis
