entomology insect behavior- communication, sound

insect movement types

kinesis, taxis

kinesis

unoriented movement in response to stimulus

orthokinesis

slow down when hit stimuli

klinokinesis

tight turns when hit stimuli

taxis

movement directly towards/away from stimuli

stimulus type- chemo

odor

stimulus type- phono

sound

stimulus type- anemo

wind

stimulus type- rheo

water current

stimulus type-telo

sight

stimulus type- thermo

temperature

stimulus type- thigmo

touch

stimulus type- hygro

moisture

stimulus type- geo

gravity

stimulus type- astro

stars, moon, sun

stimulus type- photo

light

releasers

stimuli that can trigger a behavior

FAPs (fixed action patterns)

series of behaviors that occur in a sequence- once started they cannot stop until done

voltinism

the number of generations of an insect species in a year

instar

developmental stage between molts

basic goal of immature instars is…

to eat without being eaten

basic goal of imago instars is…

to reproduce and not be eaten

stridulation

rubbing body parts together to make a sound, usually males do this

how do such small insects make such loud noises?

harp and mirror amplify vibration, leaf holes, burrows, females determine size of male by frequency, ditto males, trash talk

tymbals

special elastic membrane areas in exoskeleton, can produce sound via solid substrates

crepitation

rubbing body parts together to make grating sound

pronotum

the dorsal plate of an insect’s prothorax
